Bitcoin Wallets: What You Need to Know About the Hardware

Technical: Taproot: Why Activate?

This is a follow-up on https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/
Taproot! Everybody wants it!! But... you might ask yourself: sure, everybody else wants it, but why would I, sovereign Bitcoin HODLer, want it? Surely I can be better than everybody else because I swapped XXX fiat for Bitcoin unlike all those nocoiners?
And it is important for you to know the reasons why you, o sovereign Bitcoiner, would want Taproot activated. After all, your nodes (or the nodes your wallets use, which if you are SPV, you hopefully can pester to your wallet vendoimplementor about) need to be upgraded in order for Taproot activation to actually succeed instead of becoming a hot sticky mess.
First, let's consider some principles of Bitcoin.
I'm sure most of us here would agree that the above are very important principles of Bitcoin and that these are principles we would not be willing to remove. If anything, we would want those principles strengthened (especially the last one, financial privacy, which current Bitcoin is only sporadically strong with: you can get privacy, it just requires effort to do so).
So, how does Taproot affect those principles?

Taproot and Your /Coins

Most HODLers probably HODL their coins in singlesig addresses. Sadly, switching to Taproot would do very little for you (it gives a mild discount at spend time, at the cost of a mild increase in fee at receive time (paid by whoever sends to you, so if it's a self-send from a P2PKH or bech32 address, you pay for this); mostly a wash).
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash, so the Taproot output spends 12 bytes more; spending from a P2WPKH requires revealing a 32-byte public key later, which is not needed with Taproot, and Taproot signatures are about 9 bytes smaller than P2WPKH signatures, but the 32 bytes plus 9 bytes is divided by 4 because of the witness discount, so it saves about 11 bytes; mostly a wash, it increases blockweight by about 1 virtual byte, 4 weight for each Taproot-output-input, compared to P2WPKH-output-input).
However, as your HODLings grow in value, you might start wondering if multisignature k-of-n setups might be better for the security of your savings. And it is in multisignature that Taproot starts to give benefits!
Taproot switches to using Schnorr signing scheme. Schnorr makes key aggregation -- constructing a single public key from multiple public keys -- almost as trivial as adding numbers together. "Almost" because it involves some fairly advanced math instead of simple boring number adding, but hey when was the last time you added up your grocery list prices by hand huh?
With current P2SH and P2WSH multisignature schemes, if you have a 2-of-3 setup, then to spend, you need to provide two different signatures from two different public keys. With Taproot, you can create, using special moon math, a single public key that represents your 2-of-3 setup. Then you just put two of your devices together, have them communicate to each other (this can be done airgapped, in theory, by sending QR codes: the software to do this is not even being built yet, but that's because Taproot hasn't activated yet!), and they will make a single signature to authorize any spend from your 2-of-3 address. That's 73 witness bytes -- 18.25 virtual bytes -- of signatures you save!
And if you decide that your current setup with 1-of-1 P2PKH / P2WPKH addresses is just fine as-is: well, that's the whole point of a softfork: backwards-compatibility; you can receive from Taproot users just fine, and once your wallet is updated for Taproot-sending support, you can send to Taproot users just fine as well!
(P2WPKH and P2WSH -- SegWit v0 -- addresses start with bc1q; Taproot -- SegWit v1 --- addresses start with bc1p, in case you wanted to know the difference; in bech32 q is 0, p is 1)
Now how about HODLers who keep all, or some, of their coins on custodial services? Well, any custodial service worth its salt would be doing at least 2-of-3, or probably something even bigger, like 11-of-15. So your custodial service, if it switched to using Taproot internally, could save a lot more (imagine an 11-of-15 getting reduced from 11 signatures to just 1!), which --- we can only hope! --- should translate to lower fees and better customer service from your custodial service!
So I think we can say, very accurately, that the Bitcoin principle --- that YOU are in control of your money --- can only be helped by Taproot (if you are doing multisignature), and, because P2PKH and P2WPKH remain validly-usable addresses in a Taproot future, will not be harmed by Taproot. Its benefit to this principle might be small (it mostly only benefits multisignature users) but since it has no drawbacks with this (i.e. singlesig users can continue to use P2WPKH and P2PKH still) this is still a nice, tidy win!
(even singlesig users get a minor benefit, in that multisig users will now reduce their blockchain space footprint, so that fees can be kept low for everybody; so for example even if you have your single set of private keys engraved on titanium plates sealed in an airtight box stored in a safe buried in a desert protected by angry nomads riding giant sandworms because you're the frickin' Kwisatz Haderach, you still gain some benefit from Taproot)
And here's the important part: if P2PKH/P2WPKH is working perfectly fine with you and you decide to never use Taproot yourself, Taproot will not affect you detrimentally. First do no harm!

Taproot and Your Contracts

No one is an island, no one lives alone. Give and you shall receive. You know: by trading with other people, you can gain expertise in some obscure little necessity of the world (and greatly increase your productivity in that little field), and then trade the products of your expertise for necessities other people have created, all of you thereby gaining gains from trade.
So, contracts, which are basically enforceable agreements that facilitate trading with people who you do not personally know and therefore might not trust.
Let's start with a simple example. You want to buy some gewgaws from somebody. But you don't know them personally. The seller wants the money, you want their gewgaws, but because of the lack of trust (you don't know them!! what if they're scammers??) neither of you can benefit from gains from trade.
However, suppose both of you know of some entity that both of you trust. That entity can act as a trusted escrow. The entity provides you security: this enables the trade, allowing both of you to get gains from trade.
In Bitcoin-land, this can be implemented as a 2-of-3 multisignature. The three signatories in the multisgnature would be you, the gewgaw seller, and the escrow. You put the payment for the gewgaws into this 2-of-3 multisignature address.
Now, suppose it turns out neither of you are scammers (whaaaat!). You receive the gewgaws just fine and you're willing to pay up for them. Then you and the gewgaw seller just sign a transaction --- you and the gewgaw seller are 2, sufficient to trigger the 2-of-3 --- that spends from the 2-of-3 address to a singlesig the gewgaw seller wants (or whatever address the gewgaw seller wants).
But suppose some problem arises. The seller gave you gawgews instead of gewgaws. Or you decided to keep the gewgaws but not sign the transaction to release the funds to the seller. In either case, the escrow is notified, and if it can sign with you to refund the funds back to you (if the seller was a scammer) or it can sign with the seller to forward the funds to the seller (if you were a scammer).
Taproot helps with this: like mentioned above, it allows multisignature setups to produce only one signature, reducing blockchain space usage, and thus making contracts --- which require multiple people, by definition, you don't make contracts with yourself --- is made cheaper (which we hope enables more of these setups to happen for more gains from trade for everyone, also, moon and lambos).
(technology-wise, it's easier to make an n-of-n than a k-of-n, making a k-of-n would require a complex setup involving a long ritual with many communication rounds between the n participants, but an n-of-n can be done trivially with some moon math. You can, however, make what is effectively a 2-of-3 by using a three-branch SCRIPT: either 2-of-2 of you and seller, OR 2-of-2 of you and escrow, OR 2-of-2 of escrow and seller. Fortunately, Taproot adds a facility to embed a SCRIPT inside a public key, so you can have a 2-of-2 Taprooted address (between you and seller) with a SCRIPT branch that can instead be spent with 2-of-2 (you + escrow) OR 2-of-2 (seller + escrow), which implements the three-branched SCRIPT above. If neither of you are scammers (hopefully the common case) then you both sign using your keys and never have to contact the escrow, since you are just using the escrow public key without coordinating with them (because n-of-n is trivial but k-of-n requires setup with communication rounds), so in the "best case" where both of you are honest traders, you also get a privacy boost, in that the escrow never learns you have been trading on gewgaws, I mean ewww, gawgews are much better than gewgaws and therefore I now judge you for being a gewgaw enthusiast, you filthy gewgawer).

Taproot and Your Contracts, Part 2: Cryptographic Boogaloo

Now suppose you want to buy some data instead of things. For example, maybe you have some closed-source software in trial mode installed, and want to pay the developer for the full version. You want to pay for an activation code.
This can be done, today, by using an HTLC. The developer tells you the hash of the activation code. You pay to an HTLC, paying out to the developer if it reveals the preimage (the activation code), or refunding the money back to you after a pre-agreed timeout. If the developer claims the funds, it has to reveal the preimage, which is the activation code, and you can now activate your software. If the developer does not claim the funds by the timeout, you get refunded.
And you can do that, with HTLCs, today.
Of course, HTLCs do have problems:
Fortunately, with Schnorr (which is enabled by Taproot), we can now use the Scriptless Script constuction by Andrew Poelstra. This Scriptless Script allows a new construction, the PTLC or Pointlocked Timelocked Contract. Instead of hashes and preimages, just replace "hash" with "point" and "preimage" with "scalar".
Or as you might know them: "point" is really "public key" and "scalar" is really a "private key". What a PTLC does is that, given a particular public key, the pointlocked branch can be spent only if the spender reveals the private key of the given public key to you.
Another nice thing with PTLCs is that they are deniable. What appears onchain is just a single 2-of-2 signature between you and the developemanufacturer. It's like a magic trick. This signature has no special watermarks, it's a perfectly normal signature (the pledge). However, from this signature, plus some datta given to you by the developemanufacturer (known as the adaptor signature) you can derive the private key of a particular public key you both agree on (the turn). Anyone scraping the blockchain will just see signatures that look just like every other signature, and as long as nobody manages to hack you and get a copy of the adaptor signature or the private key, they cannot get the private key behind the public key (point) that the pointlocked branch needs (the prestige).
(Just to be clear, the public key you are getting the private key from, is distinct from the public key that the developemanufacturer will use for its funds. The activation key is different from the developer's onchain Bitcoin key, and it is the activation key whose private key you will be learning, not the developer's/manufacturer's onchain Bitcoin key).
So:
Taproot lets PTLCs exist onchain because they enable Schnorr, which is a requirement of PTLCs / Scriptless Script.
(technology-wise, take note that Scriptless Script works only for the "pointlocked" branch of the contract; you need normal Script, or a pre-signed nLockTimed transaction, for the "timelocked" branch. Since Taproot can embed a script, you can have the Taproot pubkey be a 2-of-2 to implement the Scriptless Script "pointlocked" branch, then have a hidden script that lets you recover the funds with an OP_CHECKLOCKTIMEVERIFY after the timeout if the seller does not claim the funds.)

Quantum Quibbles!

Now if you were really paying attention, you might have noticed this parenthetical:
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash...)
So wait, Taproot uses raw 32-byte public keys, and not public key hashes? Isn't that more quantum-vulnerable??
Well, in theory yes. In practice, they probably are not.
It's not that hashes can be broken by quantum computes --- they're still not. Instead, you have to look at how you spend from a P2WPKH/P2PKH pay-to-public-key-hash.
When you spend from a P2PKH / P2WPKH, you have to reveal the public key. Then Bitcoin hashes it and checks if this matches with the public-key-hash, and only then actually validates the signature for that public key.
So an unconfirmed transaction, floating in the mempools of nodes globally, will show, in plain sight for everyone to see, your public key.
(public keys should be public, that's why they're called public keys, LOL)
And if quantum computers are fast enough to be of concern, then they are probably fast enough that, in the several minutes to several hours from broadcast to confirmation, they have already cracked the public key that is openly broadcast with your transaction. The owner of the quantum computer can now replace your unconfirmed transaction with one that pays the funds to itself. Even if you did not opt-in RBF, miners are still incentivized to support RBF on RBF-disabled transactions.
So the extra hash is not as significant a protection against quantum computers as you might think. Instead, the extra hash-and-compare needed is just extra validation effort.
Further, if you have ever, in the past, spent from the address, then there exists already a transaction indelibly stored on the blockchain, openly displaying the public key from which quantum computers can derive the private key. So those are still vulnerable to quantum computers.
For the most part, the cryptographers behind Taproot (and Bitcoin Core) are of the opinion that quantum computers capable of cracking Bitcoin pubkeys are unlikely to appear within a decade or two.
So:
For now, the homomorphic and linear properties of elliptic curve cryptography provide a lot of benefits --- particularly the linearity property is what enables Scriptless Script and simple multisignature (i.e. multisignatures that are just 1 signature onchain). So it might be a good idea to take advantage of them now while we are still fairly safe against quantum computers. It seems likely that quantum-safe signature schemes are nonlinear (thus losing these advantages).

[Discussion] Let's talk about CakeWallet and how it's "marketed" here

Hello to all,
First, I want to start this discussion by specifying that I have nothing against CakeWallet, I only want to talk about their marketing on this sub-reddit nothing else.
For the past few months, I've been following this sub-reddit on a regular basis as I'm a big Monero user. I look at a lot of questions and hesitate very regularly to create an account to answer them. In doing so, I often notice new users asking how to switch from Bitcoin to Monero or others asking for a wallet where to store them. I have nothing against CakeWallet "ads" when the person themselves are looking for a place to store them (when it's not excessive) but on the other hand, I find it goes too far when a user asks how to get Monero. This is where I think the dilemma begins.
I see far too many "Use CakeWallet it offers exchange!" messages on this kind of request, if this wallet offered an internal exchange solution where no other third party is involved I would agree with it, but in this case it's not. The 2 exchangers are available online and the exchange can be done WITHOUT the need to download the application and make the exchange on it. In this case, many will say to me "But they need a wallet" or "It's more safe!" but in most cases, these users already use a wallet and don't expect to be given another one just to make an exchange, regarding the fact that it's more "secure", giving a link directly or giving the list of possible exchanges from the official website seems more suitable to me.
Here are some examples of what I am talking about: 1- https://www.reddit.com/Monero/comments/iirl1m/should_i_trust_bitni/g38xq9x/ 2- https://www.reddit.com/Monero/comments/ihl3z2/dumb_question_but/g3296x1/ 3- https://www.reddit.com/Monero/comments/igh5sd/watch_out_fake_morphtoken_website/g2vjb0u/ 4- https://www.reddit.com/Monero/comments/id105b/reverse_xmrto/g265wiy/ | https://www.reddit.com/Monero/comments/id105b/reverse_xmrto/g26zb80/
I agree with advertising in general, especially when it affects Monero, but isn't that a bit too much? Shouldn't Rule 6 come into play in such cases? Knowing that CakeWallet is a company that delivers a product, it should fall under this rule and should be limited, I find that this kind of post is just a loophole to propagate the idea of this wallet. As time goes by, I hardly see "Use the official wallet" or any other such option. Wouldn't it be a good idea to share official documentation about wallets and exchanges in general, which would allow the user to make an unbiased choice? (https://web.getmonero.org/ - Get Started "Choose a Wallet" and "Get Some Coins")
Again, I underline the fact that I have nothing against CakeWallet, I use it myself when I can't access my computer, I just find their way to advertise really excessive and would have liked to talk about it with all of you.
Constructive answers are welcome!

How to sell xBricks for money (self post for mod approval)

Preface
I've written this guide with those that are unfamiliar with crypto in mind, however it's still a lengthy process. I'm going to try to present this in a way where you don't have to learn how the underlying crypto technology works, but I will add in links to relevant concepts in case you're curious. This process was a lot more complicated before but I made a web interface to simplify it.
At the time of writing this, FortniteBR BRICKs are worth 10 cents a piece. That makes 1000 bricks worth 100 bucks. The liquidity pool is about $14,000 at the time of writing, meaning that there's room in the market for you to hypothetically get $7,000 if you had a lot of BRICKs.
If at any point throughout this process you need help, DM me!
Misc. Resources That Might Be Helpful
What you need
You will need:
Step 1: Setup
On your desktop computer, install MetaMask. This is an Ethereum Wallet which will allow you to interact with the Ethereum Network and its many sidechains. More on this later.
Follow the setup instructions in MetaMask. If you've never done this before, you'll need to create a new seed phrase. Video tutorial if you get stuck.
YOUR SEED PHRASE IS THE KEY TO YOUR WALLET. ANYONE WHO HAS ACCESS TO YOUR SEED PHRASE CAN TAKE YOUR FUNDS. IF YOU LOSE YOUR SEED PHRASE YOU HAVE NO WAY TO RECOVER YOUR FUNDS. WRITE IT DOWN AND STORE IT IN A SAFE PLACE!!! NEVER GIVE IT OUT TO ANYONE - ANYONE THAT ASKS FOR YOUR SEED PHRASE IS TRYING TO SCAM YOU! DON'T FALL FOR IT!
In the MetaMask interface, you'll see "Main Ethereum Network". This process uses two networks. One of them is the Rinkeby Testnet (where the BRICK tokens are natively) and one of them is the xDAI network which is where we will bridge the tokens to in order to exchange them for Dai, a token which is pegged to the price of the dollar.
From the dropdown, select Rinkeby Testnet. If you're in the assets tab, you should see a thing that shows your ETH balance. Below this, you should see an "add token" button. Click it. Go to "Custom Token" at the top. In "token contract address," paste in the following:
0xe0d8d7b8273de14e628d2f2a4a10f719f898450a
The other fields will autofill. Hit next. You'll now see your BRICK balance (which will be 0, you haven't transferred your bricks yet) in MetaMask if you've done everything right.
You'll need Rinkeby Ether to cover transaction fees. Since we're on a testnet, the Ether is worthless which means people hand it out for free. You can get this Ether from a variety of places:
Now it's time to get your BRICKs from your Reddit vault into your MetaMask wallet.
WARNING: ALL CRYPTO TRANSACTIONS ARE IRREVERSIBLE.
Your Ethereum address shows up under Rinkeby. It should be "0x" followed by a bunch of hex characters. Click on it to copy it to your clipboard. You now need to somehow get this to your mobile device. Email it to yourself, text it to yourself, whatever.
On your Reddit mobile app home screen, click on your profile icon and then go to vault. You'll need to set this up and claim your tokens if you haven't already. Be aware that this is also technically an Ethereum wallet. Keep your seed phrase safe.
Send however many BRICKs you want to sell to your MetaMask wallet. Check to make sure the addresses are the same, but don't worry too much about making a typo or whatever. The chances that you'd make a typo that would result in a valid Ethereum address are slim, if you get a character wrong it'll just tell you it's not a real Ethereum address and prevent you from sending.
It may show an error when you try to send. This is somewhat rare but pretty normal. They often run out of testnet Ether. Come back later and try again.
If it works properly, it'll take about a minute to go through. It may take longer than that.
Once the transaction goes through, you'll see that you have an absurd amount of BRICKs in MetaMask. No, there wasn't a glitch. The people who wrote the code for BRICKs made the decimals of precision weird for some reason. It's off by a factor of 1018. This isn't a big deal.
If you see Bricks and Ether (ETH) in your MetaMask wallet, proceed to the next step. If you're having issues, feel free to DM me.
Step 2: Getting Your BRICKs from Rinkeby to xDai
There's a LOT going on under the hood for this part (deets for those interested). Previously this required manually generating contract interactions, which is kind of a pain if you're new to Ethereum. I made a UI to make this easier (it generates the transactions for you, all you have to do is sign them with your wallet). This took way longer to do than you might guess, so feel free to help a homie out at:
0x4BCcC2569DD93C7dF43431A7b70db569dedB6187
Go to my tool. Hit connect. If you're on the Rinkeby network, it should show your balance in BRICKs. Enter the amount you want to bridge (probably all of them). If neither of us have made any mistakes, it should pop up with a request to spend your BRICKs. If there's any issue with this tool, DM me. This allows the TokenBridge contract to take your BRICKs and put them on the xDai network where you can sell them. This is the part where you'll get an error if you don't have any testnet ETH. Set the gas price to 1 (the suggested price is based on the Main Ethereum Network - it's way too high). After you approve that, it'll give you another thing to accept. This is the actual transaction where it'll bridge to xDai. Again, make sure the gas price is set to 1 and confirm the transaction.
Add xDai to MetaMask
Switch to the xDai network. We're going to add another token. Again, go to "add token" > "custom token" > "token contract address". Paste in:
0x2f9ceBf5De3bc25E0643D0E66134E5bf5c48e191
If the transactions have gone through, you should see your xBricks (the name for BRICKs that have been bridged to xDai) in MetaMask. If not, wait a bit for the transactions to go through. Sometimes there are slowdowns that cause bridging to take a while. Shouldn't take too long, though. Once that's done, you're ready for the next step.
Step 3: Trading Your xBricks for xDai
Go to Honeyswap. Hit "select a token." You'll need to paste in the xBrick address again. Here it is:
0x2f9ceBf5De3bc25E0643D0E66134E5bf5c48e191
Click xBrick.
You'll need to flipflop the trade around by hitting the arrow button. xBrick should be on top. Type in the amount of xBricks you want to sell, or hit max to sell all of them. 1 xDai = $1. You'll need to hit approve first. Set gas price to 1 again. Then you can complete the trade by hitting swap. After a bit, the xDai should show up in your wallet.
Step 4: Mainnet
Everything on Mainnet costs actual money to do. It costs about 50 cents to make a transaction and it costs about 3 bucks to use an exchange like the one we just used. If you don't have mainnet Ether, you won't be able to do anything with your mainnet Dai (what xDai is called when it's bridged back to the main Ethereum network). You may be able to find someone to lend you some ETH to make these transactions with. Whatever you do, just be aware.
If you still want to bridge your xDai into Dai, go here and make sure xDai is on the left. If it's not, go in the top right and select xDai chain. Enter the amount of xDai you want to bridge to mainnet and then hit transfer. Follow the prompts. This part may take up to an hour due to recent network congestion. After it's done, if you go back to Main Ethereum Network in MetaMask you should see your Dai.
If you have a few bucks of ETH, you can use UniSwap to convert your Dai to even more ETH. Uniswap tutorial

[Table] IAmA dark web expert, investigative journalist and true crime author. I’ve met dark web kingpins in far flung prisons and delved the murky depths of child predator forums. I’ve written six books and over a dozen Casefile podcast episodes. AMA (part 1/2)

Questions Answers
Have you ever gotten into legal trouble by exploring the dark places of the internet? Like, "sorry, officer, I was only surfing drug markets and child molester forums for my next journalism piece..." Do you worry about that? Do you have to take extra steps to protect yourself? I'm very careful not to go anywhere that it is illegal to visit. You will hear loads of stories about how easy it is to "stumble upon" child porn, but the fact is that those sites usually have names like "Preteen cuties" so you know exactly what they are, and in order to access them you have to register. So you have to make a very deliberate choice to log into them. I have no interest whatsoever in viewing any child abuse material, so I don't go into those places. When I was researching The Darkest Web, I went to the discussion forums that didn't allow any images (though they did link to sites that did), and even there I turned off images.
As for the drugs, weapons etc, there is nothing illegal about surfing them and looking around.
I do get a bit nervous every time I visit the US, especially when I was invited to a "friendly" lunch with Homeland Security once (it was reasonably friendly as it turns out, it was also terrifying)
the below is a reply to the above
Why did homeland security want to talk to you? They said it was about the murder-for-hire stuff, but some of the questions leaned toward something else
Is there anything that really concerns you about the dark web? Some of the things already discussed are beyond barbaric and that is only the stuff that has been found out about and been picked up by the media and your fantastic work. Do you think the public should expect worse and more horrific revelations from the dark web or is it just "more of the same" for lack of a better term and do you think the authorities are getting better in shutting this inhumanity down and catching the people responsible? I am definitely not against people taking back their online privacy and I actually think that buying drugs from the darknet markets is a safer and more sensible option than buying them from the dodgy dealer down the road. However the one thing that is really disturbing is that the dark web has provided a place for child predators to find each other and form communities where they support and egg each other on. Imagine a few years ago, someone who was into hurtcore could never tell anyone else and would be unlikely to ever come across another person with the same perversions. Now it is as simple as finding the relevant site on the dark web. When there are suddenly hundreds of people who all think and act in the same way, it normlalizes what they are doing.
One of the guys who got caught, Matthew Falder, was a sadist who used to crowdsource "ideas" for torturing the children and teens he was blackmailing into doing heinous things for him online. But apparently he was a "normal" intelligent popular guy
the below is a reply to the above
But how does everyone participate in those illegal sites without getting caught? You said in other comments that you tried to stay away from underaged sites because they were illegal. Can't they be tracked down, even with tor and a vpn? The thing that I don't understand is that even on the dark web people say you should stay away from illegal sites, but how are pedos not getting caught? they are getting caught, but the way they are getting caught is through painstaking detective work, looking for clues in photos, befriending them online and getting them to reveal things about themselves (what is known as social engineering). It takes a long time and many resources.
I say don't go there because (a) it is illegal and (b) you really shouldn't want to go there
Iirc you attended the trial of the person behind the horrific hurt core website that was exposed a few years back. I was wondering if there was anything in particular that happened during the trial that particularly shocked or horrified you that isn't really public knowledge or talked about? Reactions from the judge or perpetrator during the trial etc. As I remember it the guy was a fairly young loner who lived with his parents but would probably never have been expected to be behind the horrific vile things which he was found to be. Also, how did you get into investigative journalism/writing? I wrote in one of the other replies above about the little mute girl that has stayed with me. Also, at the insistence of the prosecution, the judge had to watch "Daisy's Destruction" which was a video of torture of a toddler. He put it off for two days and when he came back he was white. He didn't have the sound on, which is considered the worst part, but he still looked shell-shocked. I don't envy him.
I'll cut'n'paste re your last question: I was in London, working for one of the most conservative law firms in the world when the Global Financial Crisis hit. I liked the job but it struck me when people were losing their livelihoods that I was working for the bad guys. I'd always wanted to be a writer so when I came back to Australia I quit law and enrolled in a writing course planning to be a novelist, but I discovered I was better at journalism. I first wrote for newspapers here about Silk Road and it grew from there
the below is a reply to the above
Thanks for the reply.. that really must've been horrific for all involved from investigation to trial and for all of the victims (apart from the scum responsible of course). I guess it would be naive to assume that the end of this site did anything other than drive this depraved community even further underground. That is the part which is really scary to me but I suppose all we can do is have faith that the authorities are always close on the tail. Thank you for your work on reporting on this and raising this stuff more into the public consciousness and making people more aware of what kind of evil still lurks. It was the most disturbing two days of my life, made all the worse because they read out hours of interactions from the site where the children still had not been identified or the predators caught.
Hurt2theCore was not the last site of its kind and there are still hurtcore sites to this day on the dark web. The one hopeful thing is that there are international task forces that seem to work together really well (unlike when it comes to drugs and every law enforcement agency wants to take the lead and they all withhold info from each other). There are a lot of resources allocated to identifying predators and their victims. Sometimes this has involved some very controversial tactics, such as taking over the sites and letting them run, so that they can use social engineering techniques to identify those who are using the sites and who are actually abusing children
the below is another reply to the original answer
So daisy's destruction is real? Was it referred to by that name court? I always thought it was a myth Yes, Daisy's Destruction is real, it was referred to by name in court and the judge had to watch the 12 minutes of it that were hosted on Hurt2theCore.
The "myth" part is that it shows a murder. The toddler, Daisy, lived, though she suffered such horrific injuries she will never be able to bear children. Hopefully she was young enough that she will grow up without the memory.
However, Scully did murder at least one child, whose body was found under the floorboards of his house. it is not known whether he filmed her murder as no video evidence of it has come to light.

Thanks for answering. I actually watched a really good video on Hurt2theCore on youtube once, I think it was by a guy called Nexpo. It was really detailed and informative about the whole case - I forgot those details. Thanks again for replying, this AMA is really informative! I think I recall that one, it was from a few years ago.
An excellent podcast that came out recently is "Hunting Warhead", highly recommend a listen. It is a tough listen, but exceptionally well-told and respectfully handled
How do you detach yourself from your work? I'm an investigator for a law firm and I've had a lot of difficult working on wrongful death cases recently. Also, how did you first end up getting published? Any tips for people interested in that field? Thanks! I don't detach. When I was researching hurtcore, it was harrowing and affected me deeply. Writing that part of the book was a very slow process because I just couldn't be in that headspace for very long at a time. Once the book was written I didn't go back there.
I already had a reputation as a blogger and a freelance journalist when i pitched my book on Silk Road. I got an agent and it was auctioned off, with Pan MacMillan getting the rights. At the time, Silk Road was still going strong, and the book I wrote was about this new frontier of drug dealing that was changing the world. I was writing it "from the inside" as I had been an active part of the community for two years. However, right as I submitted the final manuscript to my publisher, Silk Road was busted and Ross Ulbricht arrested, so i had to quickly change the narrative to a "Rise and Fall" thing!
How many times have you approached law enforcement with information and how many times has the approach resulted in action? and... are there times where you know something nefarious is happening but history and the evidence at hand tells you it's not worth the effort? There is no point in approaching law enforcement to say "I have come across this site". If I've found it, you can guarantee law enforcement has found it as well.
The only time I've approached law enforcement was when I had information that they did not, which was when a friendly hacker provided me with a back door into the Besa Mafia murder-for-hire site. I got to see all the messages and orders etc. Of course LE knew about the site, but they did not have the details of the people who had hits taken out on them. We tried desperately to tell police in several countries that real people had paid real money to have other real people killed, but they just weren't interested. We sounded like crazy people talking about dark web hitmen, who were scams anyway and nobody was dead, so why should they be interested? They became much more engaged when one of the people WE HAD PREVIOUSLY TOLD THEM ABOUT later turned up dead
the below is a reply to the above
By law enforcement, do you mean only local or else the big agencies? I feel like I wouldn't tell my local police department because they wouldn't really know what to do. It would have to the the bigger agencies. FBI in US. NCA in UK. AFP in Australia. Nobody was very interested, although the FBI did visit at least one of the targets to let her know she was a target. She still wound up dead
What are some of the most prevalent uses of the dark web that AREN'T all shady and nefarious? We might be getting into semantics here, but people use Tor, which is the most possible darknet that is used to access the dark web, just for private browsing and ensuring that commercial interests aren't following them everywhere to bombard them with ads for some thing they looked up.
Some of the news organizations have a dark web presence so that whistleblowers can upload information safely. Even the CIA has a site on the dark web so that people can anonymously tip off matters of national security.
Other than that, there are just forums, where you don't have to worry that every single stupid thing you post will be saved in posterity forever, to be trotted out years later when you run for congress or something
After everything you've seen, does anything surprise you anymore or are you just numb to it at this point? Do you think there should be more education/exposure about the dark web than there is now or would that just be counter-productive as people would just find another place to hide? I'm curious to hear any favourite stories about the Psychonauts. I am not numb and I hope I never become numb. I really don't visit the horrible dark places very often, unless I'm researching something specific, and even then I don't look at pictures or videos. Most of the crime is pretty benign - I'm not fazed by people wanting a safer way to buy drugs.
I think there needs to be ongoing discussions about online activity and its misuse in general, but most crime still happens on the clearnet. The dark web is not nearly as large or prevalent as people fear.
For a long time, a dealer provided free LSD to anyone who wanted it for personal use (ie not sale) and to any organizations who were doing psychedelic therapy.
One psychonaut got busted and spent time in prison... only he still had bitcoin in a wallet and by the time he was released he was a millionaire. He would have just spent it on drugs otherwise :)
I know law enforcement has to delve into the predator side of the dark web. With what you've seen do you think it should be mandatory or an industry standard that law enforcement officials seek professional help? I couldn't imagine investigating that daily and not thinking less of humanity at some point. I'm pretty sure they do. I worked for Legal Aid for a while, and i know there were pretty strict rules in place for the lawyers who had to defend child abusers.
When I was at the trial for Lux, owner of Hurt2theCore, I met a cop whose job it was to watch all the videos and befriend the predators in an attempt to get them to slip up and reveal something of themselves. She said she had a little filing cabinet in her brain where she put all that stuff, and that making an arrest made it all worthwhile. She had made several arrests personally. She was a sex offender's worst nightmare :)
What’s one of your personal favorite investigations and what made it unique for you? By far the Besa Mafia murder-for-hire case. What made it unique was that, first, I was provided a back door into the Besa Mafia site by a friendly hacker, so i had information that nobody else had. But then I became "friends" for want of a better word with the owner of the site, Yura. Besa Mafia, of course, was not killing anyone, but Yura made a LOT of money scamming would-be murderers out of their money. We entered into a weird relationship over the years where i would report on his activities and he would try every trick under the sun to stop me from doing so, so that he could keep scamming people. He even offered me a job, helping him, because he had become so busy. He also provided me with names and details of people who had hits taken out on them so I could pass them on to law enforcement.
It all became horribly real when one of the people who had a hit put out of them wound up dead. It wasn't Yura of course, but the guy had paid him $13K before giving up on the site and doing it himself. The thing was WE HAD TOLD THE FBI about the hit and the $13K and they visited the victim, but then put it into the too-hard basket when she couldn't think who might have paid that much to kill her.
the below is a reply to the above
Wow. That’s actually pretty cool. Reminds me of an old saying. “Keep your friends close, but your enemies closer.” It's a seriously bizarre relationship. When I was hired as a consultant by CBS for a 48 Hours expose on dark web hitmen, he actually agreed to meet me in London. But he thought that CBS was going to advertise his site as the real deal and he got excited and sent them details of two people who had hits put out on them. CBS sent them straight to the police and very shortly after two arrests were made and it was all over the news, where they called his site a scam. Yura got so pissed about it, he never turned up to our meeting. They had even hired an Academy Award-nominated master of disguise makeup artist to disguise him!
are "red rooms" actually a prevalent thing, or just a widespread misconception or rumor? I ask in part because it's very easy to see, for instance, Mexican cartels dismembering people alive, etc, just on the clearnet. Hell, a couple days ago I saw a video posted of a cartel member cutting out a dude's heart while the guy was alive, and he ATE it. He fucking ATE it. So it seems plausible... The most popular myth of all is Red Rooms, where people – usually women – are tortured to death live on camera while those who have paid to watch type in torture commands in a chat box. Think the movie Hostel, with webcams. In this sense these have never been proven to exist. I get where you are coming from with the cartels, and the recent news item where they found those shipping containers set up with torture rooms freaked me out and made me wonder!
There is some truth to this rumour, but the execution is not like you see in the movies. Most notably, because it involves children, not adults abused on demand for paying pedophiles, but not to the point of death
the below is a reply to the above
The news about those shipping containers really made me speculate, since for every one person who gets caught doing something evil, there must be at least several more people who are very honed in their 'profession' doing the same evil deeds and worse, yet who evade being captured for decades. Anyway, based on morbid things I've seen, karma comes around eventually... I know, right? It really freaked me out, and then when I read that they already had intended victims for them but the police got to them first and put them in protected custody.. IMAGINE SEEING THOSE PICTURES AND KNOWING YOU WERE SUPPOSED TO BE IN THEM!! I would retire to a deserted island somewhere
the below is a reply to the above
Your line of work could easily result in something like C-PTSD down the road a little ways. I have a morbid curiosity, and have seen worse than those shipping containers had to offer. I'm sure you have as well. So one more question from you, if you don't mind: what are some proactive approaches to mental health you take to safeguard your sanity? A lot of wine. Cuddle my dog
Hi, there! This has been fascinating to read; thank you so much for sharing! I'm curious: why do you think so many people who don't want to engage with disgusting and illegal content like hurtcore find it so interesting to read about? Do you have any insight into your readership and the ethics associated with reading about these kind of topics? I think morbid fascination with the dark is exceedingly common - just look at how many people can't get enough about serial killers! In some ways it is probably a self-defense mechanism - the vast majority of true-crime readers are women. People like to be armed with knowledge. We also like to be spooked and scared.
As for my books, I don't really go into much gory detail, but the horror still shines through
Out of all 9-5 jobs out there, why this? What’s your motive? I got disenchanted by being a lawyer and I had wanted to be an author since childhood. The lawyering put me in a strong enough financial position that I could quit to do a uni course for a couple of years. My plan was to become a best-selling novelist, but my first chick-lit novel was nothing special. However, during the course, I found I did really well at journalism and was soon making a living as a freelance journo before I finished the course. My first major feature was on the Silk Road drugs market, which I had discovered thanks to a friend who was using it. Once I got in there I became fascinated by everything about it and started contacting the owner, users, vendors etc asking for stories (I was upfront about who I was). I began the first serious dark web blog - allthingsvice.com - and also became the go-to freelancer for Australian dark web stories. Then I pitched my first book and got a healthy advance for it.
I like working for myself, working from home and delving into things. Right now I have my dream job (though it wouldn't hurt to pay a bit more. I'm certainly not making anywhere near what I used to make lawyering, but I make enough to get by and I live pretty simply)
Did you ever do any writing on Brian Farrell and his role in Silk Road 2.0? I was Brian's cellmate for all of 2017 at Sheridan Federal Prison and heard all of his crazy stories. Was just curious as to the validity of them all. DoctorClu! I did write briefly about him in Silk Road, but it wasn't all positive. I remember being frustrated by the shitshow that was Silk Road 2.0 in the beginning, right after SR1 shut and when DPR2 took off and Defcon got all dramatic. It settled down after a bit and lasted a year, when it was revealed THEY HAD A FUCKING UNDERCOVER HOMELAND SECURITY OFFICER ON STAFF THE WHOLE TIME. But yeah, anyhow, they are probably true. I'd love to hear them :)
Was there ever something on the dark web that made you surprised ( in a good way) and smile ? So many things. Back in the day of the original Silk Road, I became obsessed with the forums, the people behind it, the intelligent discourse about the War on Drugs and philosophy. I found it amusing that drug dealers ran sales and giveaways. There were book clubs and movie clubs.
One of the most important people from that era was Dr Fernando Cauevilla, who became a member of Silk Road as "DoctorX". He was a real doctor who provided genuine, free, non-judgmental advice about drug use to the members of the site. It was quite an amazing time.
the below is a reply to the above
Did Ulbricht get taken down the way we were told in the news? What happened to all the Bitcoins? His arrest went down the way we were told in the news. How they located the server has never been disclosed (other than a fanciful explanation that NOBODY could believe). This explanation may be tested if Variety Jones runs a Fourth Amendment argument at his trial
The bitcoin in the wallet on Ross' computer was auctioned off by the Feds. He may have other bitcoin wallets stashed somewhere but nobody knows
the below is another reply to the original answer
Book/movie clubs on the silk road? Yeah, they would set reading and then everyone would come back and discuss the book, or they would have a time when everyone watched the same movie at the same time and chatted about it in real time
the below is a reply to the above
Haha that's amazing! I don't suppose you remember any of the books in question? They used to be a lot of philosophy books, especially on agorism. A Lodging of Wayfaring Men was one of the books. I remember V for Vendetta on a movie night
You don't seem to be pushing your most recent project and you're actually answering all the questions people ask, so I've got ask...are you some sort of government plant meant to destabilize reddit? This isn't how AMAs are supposed to work. You come in, you half ass a few questions, hawk whatever you're here to hawk, and then leave after 20 minutes. That's how it's done. lol I'm a genuine redditor from way back, and I love talking about the stuff I do. I did find that after I answered a question in an AskReddit thread a while back that blew up, the sales followed. But that was organic and I don't think you can force it to happen - Reddit can spot that a mile awy
What are some of the best things about the dark web? And can anyone get on it? Things you can buy that you can’t buy normally online? I really enjoy some of the forums, especially the psychonaut forums where people who like to trip on psychedelics get together and talk drugs and philosophy. There's a real "be kind to one another" vibe.
Getting on the dark web is easy, but not getting scammed when buying things takes a lot of homework. Yes, you can buy most things, but the most popular things are drugs and digital goods, i.e. things that depend on repeat custom and are easily transferable from seller to buyer
the below is a reply to the question
[deleted] You're doing the Good Work my man. I'd give you one of those awards if i knew how
What would you define the word "Safe" when it come to the internet (both www and dark web) world and are there any tips that I should follow to keep myself safe? It really depends on what YOU mean by safe. Tor, which is the darknet that provides access to the dark web will keep you safe from prying eyes and surveillance.
If you mean keep your information safe, the old-fashioned advice is to never reuse your password and to enable 2-Factor authentication wherever you can. Your information is quite likely somewhere on the dark web thanks to high-profile hacks of major organizations, but provided you don't re-use usernames and passwords, you really don't have to worry too much about it.
If you mean keeping yourself and/or any kid safe from predators, the only thing is to ensure you are educated about the approaches and methods they use.
Has Covid affected the Dark Web in any real way? Also I just read through all of the post comments, what incredible story’s. I would totally buy a book about the Silk Road or Yaru! re covid on the dark web, here's some notes I made for an interview I did recently:
* when Trump first hyped hydroxychloroquine as a potential miracle cure for COVID-19, drug dealers on the dark web seized on the claim.
* Listings quickly popped up on the most popular darknet markets
* A vendor on Whitehouse Market sells 100 Pills for $90, calling it a “Miracle Drug For Coronavirus” and suggesting buyers purchase in bulk to sell at a mark-up locally.
* Another makes the dubious claim “This drug will help people to beat Corona Virus” There are 11 listings on Empire Market currently, although more than half are from the one seller, who is a well-known and trusted vendor on the site.
* There were also people claiming to be selling infected blood or plasma of recovered COVID victims
* The infected blood stuff is just bullshit IMO Just because something is listed doesn’t mean it is genuinely for sale
* There's been some claims to be selling vaccines
* At the beginning there were also loads of listings for PPE
* some just used it as a marketing tactic - “fight off the virus with edible cannabis” or “relax with Xanax” and others as an excuse to raise their prices
* However, sales are low compared to sales of other drugs on the site, so it is difficult to say whether it’s something that will really catch on
* It didn’t take long for complaints to come in and market owners to clamp down on anything claiming to be a miracle cure or vaccine
* users were discouraging other users from profiting off the pandemic and requested markets provide health and safety information
* All the major markets forbid anything being sold as a cure for COVID. They flagged keywords and vendors would be told to take any listings down. They also put out PSAs telling people not to buy
* Monopoly: threatened to ban and.. “You are about to ingest drugs from a stranger on the internet - under no circumstances should you trust any vendor that is using COVID-19 as a marketing tool to peddle already questionable goods”
* It was a business decision. They don’t want anything that will attract attention or that might cause desperate people who wouldn’t normally use the DNMs to find their way there
* The idea behind DNMs generally is educated and responsible drug use. They really don’t want people dying - bad publicity and no repeat custom
* However the dark web is rife with scammers and people willing to prey on the desperate so there are still scams out there
* The only way I could ever see it becoming a thing is if there is a well-known potential cure/vaccine that is not being made widely available and could plausibly find its way onto the black market
Hi Eileen :) My question is about how you construct your Casefile episodes - I assume there is an extensive amount of outlining but do you write the final draft like a script specifically thinking about his voice? And about how long are they as far as - for example - does one hour equal 50-60 pages? Thank you. I initially write them as if I'm writing an article or book, but then go back and edit them to be read out and yes, when I do that, I do have his voice in my head lol. One episode is usually around 12,000 words. It then goes to another editor who edits the episode to be even more "casefileaa' before it finally goes to Casey
Have you been exposed to things in your investigations that have made you second-guess what you do? If so, what has made you keep going back? i've definitely had days where I question everything, but to be honest, I don't really hang around the horrible really dark places much. I did delve into the child predator forums when I was writing The Darkest Web, but I don't make it a habit to go there. The psychonauts are much more friendly
the below is a reply to the above
To continue with that- have you clicked images, links that make you a suspect in certain scenarios? Oh absolutely. Sometimes I go to a "Fresh Onion" site, which is a site that crawls all the .onion addresses (dark web URLs end in .onion rather than .com, org etc) and alerts you to any new ones. Sometimes they don't have any description, so you take a big risk clicking on any of those. The most dangerous button on the dark web is the "Random Onion" button, so I avoid that.
I'm pretty careful about what I click, but the moment something looks questionable I nope the fuck right out of there
the below is a reply to the above
Have you ever felt that you may be a suspect whether it be ok a drug site, a pedo site, etc. Have you ever been contacted by someone regarding your surfing habits? Well my actual surfing habits are protected by Tor, which means they are hidden from prying eyes, so no I haven't been contacted about them. I am very open on the dark web about who I am and what I'm doing there - I use the name OzFreelancer on all of the markets and forums. I don't go to the sites that host child abuse images - you can't un-see that shit and I don't need it in my head.
As noted in another reply, I was contacted by Homeland Security on one of my visits to the US and taken for a "friendly" lunch.
the below is another reply to the original answer
Psychonauts are more friendly than most people. Something about regular mind altering experiences makes you want to be less of a cunt. Yeah, I call The Majestic Garden a little corner of sunshine and rainbows on the dark web :)
the below is a reply to the above
More about The Majestic Garden please? What is grown there? It's a place where people talk about and source psychedelics - most notably LSD, the 2C family, DMT and MDMA. Talk about and sourcing harder drugs is forbidden. In fact the admins snuck in an autocorrect so that any time someone wrote the word "cocaine" it would post as "a raging hardon" :D
Do you fear that seeing all this stuff might turn you emotionally blunt? I'm not watching any of this stuff on purpose (even the clearnet stuff), because I fear that the more you see of it, the more normal it gets, and ultimately, the more it will fuck you up. To quote the movie 8mm... "If you dance with the devil, the devil don't change. The devil changes you." No, I can't even watch "3 Guys 1 Hammer" in its entirety, let alone look at the really dark materials on the dark web. When I was researching The Darkest Web, going into the predator forums did the opposite of making me blunt. It was the shortest section of the book but took the longest to write because it was so emotionally draining
the below is a reply to the above
I have to ask, what is "3 Guys 1 Hammer"? It's a video of two teenagers murdering an innocent man with a hammer that went viral on the gore sites of the regular internet. It's truly horrible.
The teens killed over 20 people. I wrote about them in my book Psycho.com (excuse the plug)
I heard somewhere that you foster dogs. Is that something you do to counter all the terrible humans you encounter in your research - everyone knows how dogs are better than people. How many dogs have you fostered and which one was your favourite? After my dog died I knew I didn't want to have another dog as I wanted to travel more. So I thought fostering dogs would be the answer as you give them love for a few weeks and then they go to their forever home. My first foster, Roy, was a big fat failure and now he lives here and sleeps in our bed and is the most spoiled dog alive
the below is a reply to the above
Did you then just decide to quit travelling? I don't know anything about Roy, but I already think I love him. Nah, he has family he can stay with when I go away, but any major travelling has been thwarted by COVID for now anyway. I'm in a hard lockdown city.
And I'm sure Roy would love you too, u/suckmyhugedong
Given how much you know about the dark web, what kind of crazy awful nightmares have you had? This could be a really good one. Thank you Probably the worst thing was delving into the forums where child predators gathered. I never looked at any videos or photos, but just seeing their discussions sickened me. The one thing that keeps coming back to me came out of the sentencing hearing that I attended of Lux, owner of Hurt2theCore, considered the most heinous website in history. In court they read out a conversation between him and an abuser who made videos of torture of the mute disabled child in his care. They were joking "at least she won't be able to tell anyone" . the abuser wasn't caught, at least by that stage
As an indie author, how have you sourced freelancers? Did you seek out those that have specific expertise or did you work with editors from your time as a traditionally published author? I learned to do everything myself before I started outsourcing.
I work with a professional editor who happens to be a friend of mine from back when we did a writing course together. I've been doing my own covers, but now that I have some royalties coming in, I've engaged a professional cover artist from Reedsy to develop a brand and more professional-looking covers for me. It is the hardest thing to find people you really want to work with and who are in budget.
I still haven't got the hang of email lists, newsletters or a website - they are all in a total mess at the moment and I'd love to find someone who can do them, but again it is that problem of finding the right person who is within budget
is it true that most of the internet is in the "dark web"? if so about how much percent is it? By far the biggest myth is that it 10x larger than the Internet. I mean, this should be common sense anyway, but it gets propagated by tabloid media all the time. It stems a lot from people using the terms "deep web" and "dark web" interchangably when they are different things.
The statement that 90% (or thereabouts) of the internet is hidden is true, and it is called the deep web (not the dark web). The 90% that is hidden is all those pages you won’t get to using google or any other search engines. There’s nothing scary about that – in fact it works in your favour.
The easiest example is your bank. The bank’s major page is available to anyone who searches the web (part of the 10%, also known as the “clearweb”). But once you log in, all those pages you can access that contain your personal details? Not searchable on google. Each one of those pages is part of the 90% of the deep web. Business and government intranets also make up part of the deep web. Honestly, it’s nothing to worry about.
The dark web – the hidden services available through Tor and other anonymising programs – makes up a tiny fraction of the deep web. A really, really tiny fraction. It is infinitely smaller than the clearweb.
Do you think human trafficking happens on the dark web? Last year (I think) there was a really bizarre story here in the UK about a model who was supposedly kidnapped to order, drugged and transported overseas by a group called "Black Death". The official story is that BD doesn't exist, and the kidnapper was a fantasist. Is it likely that humans are bought and sold into slavery over the dark web? There are no slick websites with auctions for slaves on the dark web, but I have no doubt that human traffickers use dark web encryption to communicate.
(here comes the second plug for the thread) - I wrote about the kidnap of Chloe Ayling and the Black Death Group in Murder on the Dark Web
What ever happened to the plural of mongoose storyline? it seems like after he was arrested in the united states, his case just fizzled away. did you ever find out any more information about yuri after he cancelled the interview with a news program? what happened with peter scully's case? i read that there was a fire where a lot of evidence against him was held and it all went up in smoke. are there any character and/or personality storylines that you feel haven't been told or are still a complete mystery? eg. tony76 1. He is still in the MCC in NY and awaiting trial. It has taken a long time because he had terrabytes of information to go through and things would have slowed down due to covid. I understand he is running the Fouth Amendment argument that Ulbricht probably should have run in the first place
2. I last heard from Yura just a few weeks ago. He is still scamming. There are some more programs in the works about him
3. Yes there was a very convenient fire, but he still got sentenced to life and i hope he rots in hell
4. I am madly curious to know what is happening with the extradition of James Ellingson, aka “MarijuanaIsMyMuse”, aka "redandwhite", MAYBE aka Tony76. I would LOVE to know that full story!
the below is a reply to the above
Wow, this shit is a blast from the past. I used to love following the darknetmarket drama. Did you write about PoM and tony76 in one of your books? Ever since reddit shut down /darknetmarket I've been out of the loop. Yes, I wrote about them in The Darkest Web
I was in touch with PoM/Mongoose when he went on a posting rampage on MyPlanetGanja, then visited him in Bangkok prison several times. Wrote all about it :)
This may have been answered by a previous post pertaining to native language barriers to specific sites on the dark web, but in your investigations, did you come across content/pages/forums from warzones? Middle East, Burma, Afghanistan, etc? If yes, what was the most memorable bit? There are loads of sites in foreign languages, but it is too difficult for me (a one-language numpty) to attempt to translate through AI, and it is not worth hiring a translator when they could just turn out to be Cat Facts

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake
https://preview.redd.it/b80c05tnb9e51.jpg?width=2550&format=pjpg&auto=webp&s=850282c1a3962466ed44f73886dae1c8872d0f31
Submitted for consideration to The Great Reddit Scaling Bake-Off
Baked by the pastry chefs at Offchain Labs
Please send questions or comments to [[email protected] ](mailto:[email protected])
1. Overview
We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too!
Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know).
To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts.
1.1 Why Ethereum
Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract.
The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both.
Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice.
1.2 Why Arbitrum
While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools.
Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users.
We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth.
2. Arbitrum at a glance
Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes.
Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability.
Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow.
Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below.
Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn.
Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask.
Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract.
Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details).
Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users.
Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum.
Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain.
Limitations
Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals.
As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit).
Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here).
So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality.
3. The recipe: How Arbitrum Rollup works
For a description of the technical components of Arbitrum Rollup and how they interact to create a highly scalable protocol with a developer experience that is identical to Ethereum, please refer to the following documents:
Arbitrum Rollup Whitepaper
Arbitrum academic paper (describes a previous version of Arbitrum)
4. Developer docs and APIs
For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/.
Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release.
5. Who are the validators?
As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators?
Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers.
Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators.
6. Reddit Contract Support
Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain.
Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain.
For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2.
Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios.
In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process.
To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum.
When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) .
The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform.
8. Benchmarks and costs
In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking.
Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here.
Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum.
On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support:
Over a 5 day period, your scaling PoC should be able to handle:
  • 100,000 point claims (minting & distributing points)
  • 25,000 subscriptions
  • 75,000 one-off points burning
  • 100,000 transfers
We provide the full costs of operating an Arbitrum Rollup chain with this usage under the assumption that tokens are minted or granted to users in batches, but other transactions are uniformly distributed over the 5 day period. Unlike some other submissions, we do not make unrealistic assumptions that all operations can be submitted in enormous batches. We assume that batch minting is done in batches that use only a few percent on an L1 block’s gas, and that other operations come in evenly over time and are submitted in batches, with one batch every five minutes to keep latency reasonable. (Users are probably already waiting for L1 finality, which takes at least that long to achieve.)
We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks).
Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c.
We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic.
Our model. Our cost model includes several sources of cost:
  • L1 gas costs: This is the cost of posting transactions as calldata on the L1 chain, as well as the overhead associated with each batch of transactions, and the L1 cost of settling transactions in the Arbitrum protocol.
  • Validator’s staking costs: In normal operation, one validator will need to be staked. The stake is assumed to be 0.2% of the total value of the chain (which is assumed to be $1 per user who is eligible to claim points). The cost of staking is the interest that could be earned on the money if it were not staked.
  • Validator computation and storage: Every validator must do computation to track the chain’s processing of transactions, and must maintain storage to keep track of the contracts’ EVM storage. The cost of computation and storage are estimated based on measurements, with the dollar cost of resources based on Amazon Web Services pricing.
It’s clear from our modeling that the predominant cost is for L1 calldata. This will probably be true for any plausible rollup-based system.
Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.)
9. Status of Arbitrum Rollup
Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade.
Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet.
10. Reddit Universe Arbitrum Rollup Chain
The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo.
If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access.
11. Even more scaling: Arbitrum Sidechains
Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide.
While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic.
The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout.
Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator.
Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol.
Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest.
We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help.
While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined).
12. How Arbitrum compares
We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects.
Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
  • As outlined throughout the proposal, we believe that the entire draw of Ethereum is in its rich smart contracts support which is simply not achievable with today's zero-knowledge proof technology. Indeed, scaling with a ZK-Rollup will add friction to the deployment of smart contracts that interact with Community Points as users will have to withdraw their coins from the ZK-Rollup and transfer them to a smart contract system (like Arbitrum). The community will be best served if Reddit builds on a platform that has built-in, frictionless smart-contract support.
  • All other Rollup protocols of which we are aware employ a centralized operator. While it's true that users retain custody of their coins, the centralized operator can often profit from censoring, reordering, or delaying transactions. A common misconception is that since they're non-custodial protocols, a centralized sequencer does not pose a risk but this is incorrect as the sequencer can wreak havoc or shake down users for side payments without directly stealing funds.
  • Sidechain type protocols can eliminate some of these issues, but they are not trustless. Instead, they require trust in some quorum of a committee, often requiring two-third of the committee to be honest, compared to rollup protocols like Arbitrum that require only a single honest party. In addition, not all sidechain type protocols have committees that are diverse, or even non-centralized, in practice.
  • Plasma-style protocols have a centralized operator and do not support general smart contracts.
13. Concluding Remarks
While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components.
But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.

Cryptocurrency Staking As It Stands Today

Cryptocurrency Staking As It Stands Today
Everyone and his grandma know what cryptocurrency mining is. Well, they may not indeed know what it actually is, in technical terms, but they have definitely heard the phrase as it is hard to miss the news about mining sucking in energy like a black hole gobbles up matter. On the other hand, staking, its little bro, has mostly been hiding in the shadows until recently.
by StealthEX
Today, with DeFi making breaking news across the cryptoverse, staking has become a new buzzword in the blockchain space and beyond, along with the fresh entries to the crypto asset investor’s vocabulary such as “yield farming”, “rug pull”, “total value locked”, and similar arcane stuff. If you are not scared off yet, then read on. Though we can’t promise you won’t be.

Cryptocurrency staking, little brother of crypto mining

There are two conceptually different approaches to achieving consensus in a distributed network, which comes down to transaction validation in the case of a cryptocurrency blockchain. You are most certainly aware of cryptocurrency mining, which is used with cryptocurrencies based on the Proof-of-Work (PoW) consensus algorithm such as Bitcoin and Ether (so far). Here miners compete against each other with their computational resources for finding the next block on the blockchain and getting a reward.
Another approach, known as the Proof-of-Stake (PoS) consensus mechanism, is based not on the race among computational resources as is the case with PoW, but on the competition of balances, or stakes. In simple words, every holder of at least one stake, a minimally sufficient amount of crypto, can actively participate in creating blocks and thus also earn rewards under such network consensus model. This process came to be known as staking, and it can be loosely thought of as mining in the PoS environment.
With that established, let’s now see why, after so many years of what comes pretty close to oblivion, it has turned into such a big thing.

Why has staking become so popular, all of a sudden?

The renewed popularity of staking came with the explosive expansion of decentralized finance, or DeFi for short. Essentially, staking is one of the ways to tap into the booming DeFi market, allowing users to earn staking rewards on a class of digital assets that DeFi provides easy access to. Technically, it is more correct to speak of DeFi staking as a new development of an old concept that enjoys its second coming today, or new birth if you please. So what’s the point?
With old-school cryptocurrency staking, you would have to manually set up and run a validating node on a cryptocurrency network that uses a PoS consensus algo, having to keep in mind all the gory details of a specific protocol so as not to shoot yourself in the foot. This is where you should have already started to enjoy jitters if you were to take this avenu entirely on your own. Just think of it as having to run a Bitcoin mining rig for some pocket money. Put simply, DeFi staking frees you from all that hassle.
At this point, let’s recall what decentralized finance is and what it strives to achieve. In broad terms, DeFi aims at offering the same products and services available today in the traditional financial world, but in a trutless and decentralized way. From this perspective, DeFi staking reseblems conventional banking where people put their money in savings accounts to earn interest. Indeed, you could try to lend out your shekels all by yourself, with varying degrees of success, but banks make it far more convenient and secure.
The maturation of the DeFi space advanced the emergence of staking pools and Staking-as-a-Service (SaaS) providers that run nodes for PoS cryptocurrencies on your behalf, allowing you to stake your coins and receive staking rewards. In today’s world, interest rates on traditional savings accounts are ridiculous, while government spending, a handy euphemism for relentless money printing aka fiscal stimulus, is already translating into runaway inflation. Against this backdrop, it is easy to see why staking has been on the rise.

Okay, what are my investment options?

Now that we have gone through the basics of the state-of-the-art cryptocurrency staking, you may ask what are the options actually available for a common crypto enthusiast to earn from it? Many high-caliber exchanges like Binance or Bitfinex as well as online wallets such as Coinbase offer staking of PoS coins. In most cases, you don’t even need to do anything aside from simply holding your coins there to start receiving rewards as long as you are eligible and meet the requirements. This is called exchange staking.
Further, there are platforms that specialize in staking digital assets. These are known as Staking-as-a-Service providers, while this form of staking is often referred to as soft staking. They enable even non-tech savvy customers to stake their PoS assets through a third party service, with all the technical stuff handled by the service provider. Most of these services are custodial, with the implication being that you no longer control your coins after you stake them. Figment Networks, MyContainer, Stake Capital are easily the most recognized among SaaS providers.
However, while exchange staking and soft staking have everything to do with finance, they have little to nothing to do with the decentralized part of it, which is, for the record, the primary value proposition of the entire DeFi ecosystem. The point is, you have to deposit the stakable coins into your wallet with these services. And how can it then be considered decentralized? Nah, because DeFi is all about going trustless, no third parties, and, in a narrow sense, no staking that entails the transfer of private keys. This form of staking is called non-custodial, and it is of particular interest from the DeFi point of view.
If you read our article about DeFi, you already know how it is possible, so we won’t dwell on this (if, on the off chance, you didn’t, it’s time to catch up). As DeFi continues to evolve, platforms that allow trustless staking with which you maintain full custody of your coins are set to emerge as well. The space is relatively new, with Staked being probably the first in the field. This type of staking allows you to remain in complete control of your funds, and it perfectly matches DeFi’s ethos, goals and ideals.
Still, our story wouldn’t be complete if we didn’t mention utility tokens where staking may serve a whole range of purposes other than supporting the token network or obtaining passive income. For example, with platforms that deploy blockchain oracles such as Nexus Mutual, a decentralized insurance platform, staking tokens is necessary for encouraging correct reporting on certain events or reaching a consensus on a specific claim. In the case of Nexus Mutual, its membership token NXM is used by the token holders, the so-called assessors, for validating insurance claims. If they fail to assess claims correctly, their stakes are burned.
Another example is Particl Marketplace, a decentralized eCommerce platform, which designed a standalone cryptocurrency dubbed PART. It can be used both as a cryptocurrency in its own right outside the marketplace and as a stakable utility token giving stakers voting rights facilitating the decentralized governance of the entire platform. Yet another example is the instant non-custodial cryptocurrency exchange service, ChangeNOW, that also recently came up with its stakable token, NOW Token, to be used as an internal currency and a means of earning passive income.

What’s next?

Nowadays, with most economies on pause or going downhill, staking has become a new avenue for generating passive income outside the traditional financial system. As DeFi continues to eat away at services previously being exclusively provided by conventional financial and banking sectors, we should expect more people to get involved in this activity along with more businesses dipping their toes into these uncharted waters.
Achieving network consensus, establishing decentralized governance, and earning passive income are only three use cases for cryptocurrency staking. No matter how important they are, and they certainly are, there are many other uses along different dimensions that staking can be quite helpful and instrumental for. Again, we are mostly in uncharted waters here, and we can’t reliably say what the future holds for us. On the other hand, we can go and invent it. This should count as next.

Why i’m bullish on Zilliqa (long read)

Edit: TL;DR added in the comments
 
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
 
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction
 
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
 
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
 
Decentralisation
 
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. The faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time-stamped so you’ll start right away with a platform introduction, roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
 
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships
 
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!

Coinbase - How to Find your Bitcoin wallet address - YouTube How To Send Bitcoin Wallet to Wallet Transfer - YouTube How to Send Bitcoin and Other Cryptocurrencies from One Wallet to Another How To Transfer Bitcoin From Coinbase To Your Own Wallet ... How To Access & Sell Your Bitcoin Cash - Trezor

Here, you can find, per option, how to access your BCH. Full Node Wallet. Our first recommendation was to use a full node wallet, like Bitcoin Core or Bitcoin Knots. These wallets store your private keys in a dedicated folder on your computer. You can make a backup of this folder using the menu in your wallet, and select: “Backup wallet”. Receiving Bitcoin. Open your Bitcoin.com wallet app and select Receive. Choose which wallet you want to receive Bitcoin to. Make sure you select a BCH wallet if you are receiving Bitcoin Cash or a BTC wallet if you are receiving Bitcoin. Your chosen wallet will generate an address that lets you receive coins.
