Running A Full Node - Bitcoin

Feather - free, open-source Monero desktop wallet releasing soon™

For the past year tobtoht and I have been working on the foundations of a new Monero desktop GUI called Feather for Mac OS and Linux platforms (Windows tentative) using Qt5, libwallet, QtWidgets.
The goal of this new wallet is to provide a practical, robust and easy-to-use Monero wallet for every day use. It aims to be beginner friendly, but should also cater to the needs of experienced Monero users with the addition of advanced features like coin control and multisig.
Feather's user interface is inspired by Bitcoin's Electrum wallet, but adapted to fit Monero. Feather is not a fork of Electrum, all of the UI code was written from scratch in C++ / QtWidgets.
Development began in the summer of 2019. We estimate to release a beta version in November or December.

Our primary motivation is to create a wallet that we ourselves would want to use and recommend to friends. There aren't many options when it comes to non-custodial Monero desktop wallets. The CLI is an excellent tool for power-users, but is simply not an option for users that are not familiar with with the terminal. The GUI has a slick user interface, but is demanding on system resources due the use of Qt Quick.
Instead we've taken inspiration from Bitcoin's Electrum and started working on the most basic looking Monero desktop wallet one can imagine. We've gotten rid of a lot of functionality, but also added new functionality. Just focussing on the basics results in a clean, robust, and beginner proof wallet.


In an effort to mitigate unintentional off-chain linking, we have made it harder to reuse addresses by automatically hiding used subaddresses. We find that the primary address leads uninformed users to believe that it is somehow functionally incompatible with subaddresses, or that funds sent to subaddresses can not be spent together. To encourage the use of subaddresses the primary address is hidden by default, and only used for change and coinbase outputs.
Our wallet supports advanced coin control features like freeze/thaw and sweeping a single output. In the future we may add manual transaction input selection.
There is no need to manually setup Tor to protect your traffic, Feather comes bundled with Tor. By default all traffic is routed through Tor with the exception of traffic between wallet and daemon. Wallet synchronization over Tor takes substantially longer than over clearnet, but you can optionally enable to connect to remote nodes over Tor. If your machine already has a Tor daemon running Feather can use the system daemon when instructed.
Just like in the official GUI, Feather essentially has 2 modes of connecting to the Monero network. You either host your node somewhere (localhost/LAN/internet) or we'll provide you one from a list of trusted, stable, community hosted remote nodes (like Cake Wallet). If Feather detects that it's running on Tails or Whonix it will automatically connect to a random .onion remote node.


Feather is built with Qt Widgets, providing native looks and performance. In a recent test™ a wallet with 10k+ transactions only consumed 200 MB ram (before optimizations). In comparison, the official GUI uses 400 MB before a wallet is opened.
GPU power is plenty nowadays so this hardly a problem, however, we are serious about providing an user interface that feels snappy to use. The application itself starts within 1-2 seconds on most machines (Bitcoin's Electrum is more like 4-5 seconds due to their usage of PyQt).

User experience

We have implemented Tevador's 14 word seed scheme with embedded restore height. The same function is used to derive the private view key from the private spendkey, therefore it is possible to convert the 14 word seed into a standard 25 word seed in case you want to restore the wallet using the official wallet software.
Feather connects to a websocket server over Tor to obtain miscellaneous data such as: price information, a list CCS proposals, posts on /Monero, the most recent blockheight, a list of community hosted nodes and the latest version of Feather.
The websocket server itself is open-source and self-hostable. By default Feather will connect to a server hosted by the project maintainers. The websocket connection can be disabled completely, but some functionality will be disabled/broken.
Our target audience are users who want to use Monero without too many issues and we've designed the wallet as such, with lots of convenience features, while routing it all over Tor in the background.
The native look of the application should feel familair to users as it behaves like any other program that runs on their computer. Added benefit for future contributors/developers is that it's very fast to implement/test UI components by borrowing from QtWidget's vast library. This in contrast with the Monero GUI, which uses custom QML components - a tricky and time consuming rendereframework more suited for large teams to create electron-like applications.

Additional information


Work started early summer 2019. We still have some features to finish, prepare CI/CD, etc. As such we expect an alpha or beta release in December 2020. For this we would like the community's approval to allow the milestones defined in GUI CCS to be used for the remainder of this project, paid in full - we can use the support. Consequently all code will be licensed under the Monero Project and features/changes to libwallet or wallet2 will be committed to upstream (Monero GUI/core). Future development and releases will be maintained by dsc__ and tobtoht.

Beta testing

Idle in #feather on if you want to help beta testing in a month or so. You will need Linux, as this is our primary platform for developing the application.
Please let us know what you think in the comments. We're open to suggestions/feature requests/brainfarts.

Funds never received. What did I do wrong?

Sorry if this is a boring or redundant topic, but I just can't find an answer. This is my first attempt at a Monero transaction.
I downloaded and installed the Monero Windows GUI app. I handled the antivirus issues, and the network is showing as connected, with both Daemon and Wallet synchronized.
I used Changelly to exchange Bitcoin to XMR from a Coinbase account.
The transaction seemed to work smoothly, and Changelly is telling me the funds have been moved successfully.
My Monero wallet does not show any received funds.
When I compare the wallet's primary address and the address listed in the confirmed transaction, the appear identical.
What could have possibly gone wrong? How do I debug this?

How To Stake/Mine Coinevo

EVO Staking/Evo mining

Evo uses Proof of Stake consensus mechanism, which is different from Bitcoin's PoW (Proof of Work). Evo mining process in PoS system is called staking. The block producer will get 6.5EVO, as well as the transaction fees and gases as block reward. So the real reward is usually more than 6.5 evo in total.
Basic requirements for staking:
  1. Run a Coinevo fullnode, and keep online (Since Coinevo is using PoS, we don't need any mining machine, just PC or even Raspberry Pi can run a fullnode);
  2. Have some EVO in the wallet (fullnode)(Any amount of EVO can be used for staking, more EVO means higher possibility to stake).
If you have no EVO yet, please get some from market before you doing following staking settings.
Currently, Coinevo Core wallet is the only wallet that support Coinevo PoS staking. Note that other wallets like mobile wallet and Evo Electrum are not able to stake for the time being.
Two ways to stake:
Either way works in the same way for staking, so you can choose either method you like.

Method 1:Staking with evod (command line)

1. Run evod

Follow the guidance to run evod :
./evod -daemon 
Staking is default on for evod, so no need for other options if you only want to stake.

2. Send some EVO to your wallet

First you can generate a new address with:
./evo-cli getnewaddress 
This will generate a new address with Prefix '1'. You can send some EVO to this new generated address for staking. You can generate as many addresses as you like, and send arbitrary EVO as you like for staking.
Note:The coin should wait for 500 blocks before being able to stake, i.e. about 17 to 24 hours to MATURE..
After the EVO node syncing to the latest block, you can check current balance with ./evo-cli getbalance or get utxo list with./evo-cli listunspent
Please do following steps after your coin is mature.

3. Check staking info

Check current staking info with:
./evo-cli getstakinginfo 
You might get the result like this:
{ "enabled": true, "staking": true, "errors": "", "currentblocktx": 0, "pooledtx": 0, "difficulty": 3693409.779133397, "search-interval": 1577, "weight": 309584575558555, "netstakeweight": 1948540143266404, "expectedtime": 805 } 
enabled means if your wallet have enabled staking, it should be true by default. staking means if your wallet is currently staking (mining). weight stands for the amount of EVO that is staking right now, with unit 10^-8EVO, here in the example, we have 0.532EVO staking. expectedtime stands for the expected time that you will get a reward, the unit is second.

4. How to stake if the wallet is encrypted?

If your wallet is not encrypted, you can skip this section. However, for security, we recommand you encrypt your wallet.
Coinevo wallet can be encrypted with encryptwallet . However, staking will be stopped when it is encrypted. For example, ./evo-cli getstakinginfo for a encrypted wallet:
{ "enabled": true, "staking": false, "errors": "", "currentblocksize": 1000, "currentblocktx": 0, "pooledtx": 94, "difficulty": 5788429.670171153, "search-interval": 0, "weight": 53206430, "netstakeweight": 2438496688951881, "expectedtime": 0 } 
See staking turns to false , which means wallet is not staking.
You can use walletpassphrase to unlock wallet for staking:
./evo-cli walletpassphrase "" 99999999 true 
After unlocking, you can double check getstakinginfo , it should look the same with previous unlocked result, staking become true.

Method 2: Staking with evo-qt wallet (official PC wallet)

Current supported platform: Mac/Linux/Windows.

1. Open Evo qt wallet

Launch the wallet.

2. Send some EVO to your wallet

If you already have some EVO in your wallet, you might skip this step.
Note:The coin should wait for 500 blocks before being able to stake, i.e. about 17 to 24 hours to MATURE..

3. Check staking status

The flash sign at the bottom of wallet shows staking info :
Solid black flash means it is staking now. For more information, you can put your mouse on the flash, e.g.:
Hollow flash measn it is not staking
Possible reasons for not staking:
No flash sign means staking is disabled

About block reward

The block producer will get more than 6.5 EVO rewards, something to keep in mind:

How to disable staking?

Staking is by default enabled for Coinevo wallet. If you need to disable staking for some reason (for example exchanges are always recommanded to disable staking), you might following anyone of the 3 ways below:
1 Add -staking=false when running Coinevo node:
./evod -staking=false -daemon 
For qt wallet, it is like:
./evo-qt -staking=false 
2 Add config staking=false in evo.conf;
3 Encrypt wallet, since encrypted wallet will automatically stop staking.

#Reddcoin ($RDD) Core Wallet Release 3.0.1 - PosV v2 SuperMajority Consensus Upgrade at 45.6% - Required Upgrade

Reddcoin (RDD) Core Wallet v3.0.1 - January 09, 2020
Version 3.0.1 is the official release version of Reddcoin Core. It is available for download at Reddcoin Core's Github repository here:
This release features PoSV v2.supermajority activation and new staking ruleset (and minor misc fixes). v3.0.1 is still not yet MacOS Catalina compatible. We are still working and should have that fix issued very soon. Sincere apologies to our Mac-using ReddHeads.
It is particularly important that all users upgrade, as once PoSV v2 is enforced, version 4 blocks will be rejected from the network entirely.
Therefore v3.0.1 is a "strongly recommended" update for all users. Note: If you have already installed v3.0.0, this upgrade is not required. If you have not yet upgraded from v2.0.x or earlier, this is a REQUIRED upgrade. Please install the newest version v3.0.1 to avoid losing functionality during supermajority activation of PoSV v2.
Reddcoin Core version 3.0.1 is now available from: Release Notes are available here and replicated below in this announcement:
This is a new major version release of Reddcoin.
Previously, the original and subsequent versions of Reddcoin were taken from a fork of the Litecoin code base.
With the release of Reddcoin V2.0.0, the code was based directly from a fork of Bitcoin. This allows for better source control and feature implementation from upstream changes into the future
With the release of Reddcoin V3.0.0, the PoSV stake reward has been improved to allow for a target 5% network growth, in process re-incentivizing individual network stakers and providing for integrated dev support.
Upgrading to this release is strongly recommended and required for continued operation. Once a supermajority of 90% is reached, old wallets will no longer accept the new v5 blocks.
Please report bugs using the issue tracker at github:
How to Upgrade
If you are running an older version of Reddcoin, shut it down. Wait until it has completely shut down (which may take a few minutes for older versions). Run the installer (on Windows) or just copy over /Applications/Reddcoin-Qt (on Mac) or reddcoind/reddcoin-qt (on Linux).
Start wallet. All done!
Reddcoin v3.0.0 introduced an updated PoSV method to better distribute staking rewards and target a overall 5% network growth. Staking and relay policy enhancements 
To implement PoSV v2, Reddcoin Core's block templates are now for version 5 blocks only. When PoSV v2 consensus (Supermajority 9000/10000) is reached, only v5 blocks will be accepted by the network.This equates to approximately 90% of blocks being generated over 1 week period. Status at any time may be viewed in node debug.log

AMA/Tutorial: Run a full node on AWS free tier with local LAN storage

AMA/Tutorial: Run a full node on AWS free tier with local LAN storage
This is a tutorial/AMA on how you can be running a full node, in the AWS cloud, for very low cost or even free.
I used to run a node on my local network but there is a problem with this; your public IP is broadcast, and then it gets associated with Bitcoin. Node owners are likely to own Bitcoin, and this raises your personal threat profile, validated against my IDS/IPS logs.
Run a VPN? Many VPNs are automatically blocked, or sketchy. Tor is also blocked on a large portion of the internet. Neither provide you with a real static IP, and that helps out the network.
There is a easy solution to this; run a node on the AWS free tier, and use an elastic IP so you have a static address. Bandwidth is free in, and low cost out, and you can control how much of that you use easily, and control your spent. The problem is that Amazon charges a LOT for online storage and even with a 1MB blocksize, the blockchain is very large and growing steadily! We mitigate this by using a VPN back to your network, where you can store the blockchain on a SMB share.
It is not complicated to do, but there are very many moving pieces to keep track of and configure. In order to fully trust your node, the best way is to build it from scratch. This is my goal in walking you through the process.
There are lots of ways to accomplish this same task; I only want to present one that works, and you can go from there. Once you have access to the blockchain in the cloud for reasonable prices, you can also look at things like the Lightning Network.
This article makes four major assumptions:

  1. That you have a OpenVPN server on your network and know how to configure it. I use pfSense and OpenVPN; others will work just as well, but you'll need to do a little work to figure out the particulars. If you don't know how, do not fret! There are loads of good tutorials for just about every platform. Or ask below. I also limited the user with access to the share at the firewall specifically to the IP hosting the share to lower the threat envelope.
  2. That you have the blockchain downloaded locally and reasonably up to date. If you don't, head on over to and download it for OSX or Windows or Linux, whatever you use for your workstation. Follow the directions to set up the software and download/synchronize it to the network. This will take awhile! Once you've synchronized, copy the data directory to your SMB share you want the AWS instance to access. You could also synchronize everything directly on AWS too, but it will likely take longer and may cost a bit for the bandwidth.
  3. That you're on windows. OSX and Linux will have slightly different processes to connect to the instance via the terminal and SSH. If you need help, ask, and I am sure we can get you fixed up.
  4. That you've read the excellent full node tutorial here:

With that, on with the show!
First: Head on over to and make yourself an account.
Once you've set up you'll need to start the process of creating a virtual machine on AWS. Look for this graphic and click on it:

Start by launching a new machine

Follow the rabbit hole, and you'll be looking to create a plain jane Amazon AMI Linux instance. It looks like this:

Pick the basic AMI instance
Keep in mind you want to pick the x86 version, which is the default.

Continue clicking, you'll want to select the t2.micro instance that is eligible for the free tier for new accounts.

Pick the free tier. You can also upgrade to the smaller tier for more ram, but the micro works for now.
Now, you're going to need a way to connect to your soon-to-be-created node in the cloud. Amazon uses SSH keys to do this, so the next step means you're going to make some. You need to save this file, as if you lose it, you won't be able to access your node anymore. Much like your wallet private keys!

Beware losing your keys!

If you've made it this far, you're almost launched!
Now we need to convert the key to a format that we can use to connect to the instance from Windows. I recommend using Putty! if you don't have it already; if you're on OSX or Linux, you likely have what you need already.
Follow the guide here to get connected:

Next you'll need to set up a opening in the firewall if you want incoming connections. This is done by adding to the security group in the "Network and Security" section; edit it to look like this:

Change the inbound security rules for the instance to accept incoming connections on 8333.

The hard part is over!
Optional: Configuring a static IP. Amazon calls their implementation "elastic" IPs, but it's really a static IP that you can move around between instances very easily. It will ensure your public address on AWS does not change; it isn't required, but it is better if you intend on allowing outgoing connections.
Go back to the main dashboard display.
In "Network and Security", click on "Elastic IPs".
Select Allocate New Address (blue button on top) and then select it in the table. In actions, you will see "Associate Address". Select this then assign the address to the instance you have previously configured. Done!

Next up: Log into your machine, and immediately update everything. Use the IP provided by Amazon, or the Elastic IP if you assigned one to the instance in the last step.
type: "sudo yum update"

Now, let's get the VPN configured.
First step is to install OpenVPN. We need to install the extended package library to do this.
type: "sudo amazon-linux-extras install epel"
type: "sudo yum-config-manager --enable epel"
Now you can install OpenVPN.
type: "sudo yum install openvpn"
You will need your credential file from OpenVPN; it's a file you generate that will have a .ovpn extension. But you're going to need to upload it to the instance. You can do this through the scp command on OSX or Linux, but if you're on Windows, you'll need another utility. Get WinSCP here:
But we'll have to tell it where your key file is so you can login. Select "New Session", then use the same IP and username as you did to connect before. We'll need to tell it about the key file though! Select the "Advanced" tab then under the SSH section, click on "Authentication" and then select your private key file you generated in the tutorial above.
Connect and upload the .ovpn file that you generated when you added a user for the VPN. This step depends on your OpenVPN configuration - ask below if you have problems.
Next, let's verify we can connect to the VPN!
type: "openvpn --config my-configuration-file-made-by-openvpn.ovpn &"
You will be prompted for a password if you configured one.
Verify operation by pinging your LAN router, e.g.
type: "ping" or the address of the SMB server where you shared the information.

Allllrighty! Next up is getting connected to your blockchain. Create a directory where the data directory will be mounted.
type: "mkdir blockchain"
We need to install samba and some utilities to get things mounted.
type: "sudo yum install samba"
type: "sudo yum install cifs-utils"

Now let's mount the folder:
type: "sudo mount -t cifs // ./blockchain -o user=bitcoin,vers=2.0,uid=ec2-user,gid=ec2 user,file_mode=0777,dir_mode=0777"
Where " //" is the address of the SMB server and share where you put the data directory from your initial sync. If you didn't, and just want to sync everything from AWS, then make sure it's a folder where your user has access. In this case, I'm assuming you've made a SMB user with the name "Bitcoin". The command will prompt you for the password to access the share. The other bits ensure you can have read and write access to the share once it's mounted in AWS.

Now we're ready for some Bitcoin! Props to the tutorial here:
But I'll summarize for you:
Download and then re-upload with WinSCP, or download directly to your instance with wget, the most current Bitcoin core. In this case, it's bitcoin-0.18.0-i686-pc-linux-gnu.tar.gz downloaded from
Let's verify it hasn't been tampered with once you have it uploaded to the terminal:
type: "sha256sum bitcoin-0.18.0-i686-pc-linux-gnu.tar.gz"
Then compare that with the hash value that's listed in the SHA256SUMS.asc file on In this case, "36ce9ffb375f6ee280df5a86e61038e3c475ab9dee34f6f89ea82b65a264183b" all matches up, so we know nobody has done anything evil or nefarious to the file.
Unzip the file:
type: "tar zxvf bitcoin-0.18.0-i686-pc-linux-gnu.tar.gz"
There is a warning about a symbolic link; everything seems to work OK regardless, but if anyone knows what or how to fix, please comment.
We'll need to get some missing libraries before we can run it; these aren't in the basic AMI instance.
type: "sudo yum install glibc.i686"
type: "yum install"

FINALLY! We are ready to launch the program. Go to the "bin" directory inside where you unzipped the Bitcoin Core tarball. (e.g. /home/ec2-useblockchain/bitcoin-0.18.0/bin)
./bitcoind -datadir=/home/ec2-useblockchain/data
You will see the program either start to sync and download, or start to read the existing blockchain file that you put in the share from before.


There are a couple extra steps to have it automatically start on reboot, but let's see if anyone gets this far first. I use the "screen" program to do this, but there's also a daemon mode, and some other functionality that is discussed in the hackernoon tutorial.
The primary cost will be outgoing bandwidth. AWS charges $0.10/GB beyond 15GB; You can limit the outgoing bandwidth easily according to your budget:

Hope this encourages people to try running a free, or very low cost, cloud node, with a substantially reduced threat profile.

Dogecoin Daemon on Windows Server?

Hey there, I've got a Windows server and am trying to get a pool going on it, but I'm stuck at the daemon. All the documentation on it only talks about compiling the daemon on linux. Is there a way to get the daemon compiled and running on Windows? Thanks in advance.

⚡ Lightning FAQs ⚡

If you can answer please PM me and include source if possible. Feel free to help keep these answers up to date and as brief but correct as possible
Is Lightning Bitcoin?
Yes. You pick a peer and after some setup, create a bitcoin transaction to fund the lightning channel; it’ll then take another transaction to close it and release your funds. You and your peer always hold a bitcoin transaction to get your funds whenever you want: just broadcast to the blockchain like normal. In other words, you and your peer create a shared account, and then use Lightning to securely negotiate who gets how much from that shared account, without waiting for the bitcoin blockchain.
Is the Lightning Network open source?
Yes, Lightning is open source. Anyone can review the code (in the same way as the bitcoin code)
Who owns and controls the Lightning Network?
Similar to the bitcoin network, no one will ever own or control the Lightning Network. The code is open source and free for anyone to download and review. Anyone can run a node and be part of the network.
I’ve heard that Lightning transactions are happening “off-chain”…Does that mean that my bitcoin will be removed from the blockchain?
No, your bitcoin will never leave the blockchain. Instead your bitcoin will be held in a multi-signature address as long as your channel stays open. When the channel is closed; the final transaction will be added to the blockchain. “Off-chain” is not a perfect term, but it is used due to the fact that the transfer of ownership is no longer reflected on the blockchain until the channel is closed.
Do I need a constant connection to run a lightning node?
Not necessarily,
Example: A and B have a channel. 1 BTC each. A sends B 0.5 BTC. B sends back 0.25 BTC. Balance should be A = 0.75, B = 1.25. If A gets disconnected, B can publish the first Tx where the balance was A = 0.5 and B = 1.5. If the node B does in fact attempt to cheat by publishing an old state (such as the A=0.5 and B=1.5 state), this cheat can then be detected on-chain and used to steal the cheaters funds, i.e., A can see the closing transaction, notice it's an old one and grab all funds in the channel (A=2, B=0). The time that A has in order to react to the cheating counterparty is given by the CheckLockTimeVerify (CLTV) in the cheating transaction, which is adjustable. So if A foresees that it'll be able to check in about once every 24 hours it'll require that the CLTV is at least that large, if it's once a week then that's fine too. You definitely do not need to be online and watching the chain 24/7, just make sure to check in once in a while before the CLTV expires. Alternatively you can outsource the watch duties, in order to keep the CLTV timeouts low. This can be achieved both with trusted third parties or untrusted ones (watchtowers). In the case of a unilateral close, e.g., you just go offline and never come back, the other endpoint will have to wait for that timeout to expire to get its funds back. So peers might not accept channels with extremely high CLTV timeouts. -- Source
What Are Lightning’s Advantages?
Tiny payments are possible: since fees are proportional to the payment amount, you can pay a fraction of a cent; accounting is even done in thousandths of a satoshi. Payments are settled instantly: the money is sent in the time it takes to cross the network to your destination and back, typically a fraction of a second.
Does Lightning require Segregated Witness?
Yes, but not in theory. You could make a poorer lightning network without it, which has higher risks when establishing channels (you might have to wait a month if things go wrong!), has limited channel lifetime, longer minimum payment expiry times on each hop, is less efficient and has less robust outsourcing. The entire spec as written today assumes segregated witness, as it solves all these problems.
Can I Send Funds From Lightning to a Normal Bitcoin Address?
No, for now. For the first version of the protocol, if you wanted to send a normal bitcoin transaction using your channel, you have to close it, send the funds, then reopen the channel (3 transactions). In future versions, you and your peer would agree to spend out of your lightning channel funds just like a normal bitcoin payment, allowing you to use your lightning wallet like a normal bitcoin wallet.
Can I Make Money Running a Lightning Node?
Not really. Anyone can set up a node, and so it’s a race to the bottom on fees. In practice, we may see the network use a nominal fee and not change very much, which only provides an incremental incentive to route on a node you’re going to use yourself, and not enough to run one merely for fees. Having clients use criteria other than fees (e.g. randomness, diversity) in route selection will also help this.
What is the release date for Lightning on Mainnet?
Lightning is already being tested on the Mainnet Twitter Link but as for a specific date, Jameson Lopp says it best
Would there be any KYC/AML issues with certain nodes?
Nope, because there is no custody ever involved. It's just like forwarding packets. -- Source
What is the delay time for the recipient of a transaction receiving confirmation?
Furthermore, the Lightning Network scales not with the transaction throughput of the underlying blockchain, but with modern data processing and latency limits - payments can be made nearly as quickly as packets can be sent. -- Source

Bitcoin Stack Exchange Answer
How would the lightning network work between exchanges?
Each exchange will get to decide and need to implement the software into their system, but some ideas have been outlined here: Google Doc - Lightning Exchanges
Note that by virtue of the usual benefits of cost-less, instantaneous transactions, lightning will make arbitrage between exchanges much more efficient and thus lead to consistent pricing across exchange that adopt it. -- Source
How do lightning nodes find other lightning nodes?
Stack Exchange Answer
Does every user need to store the state of the complete Lightning Network?
According to Rusty's calculations we should be able to store 1 million nodes in about 100 MB, so that should work even for mobile phones. Beyond that we have some proposals ready to lighten the load on endpoints, but we'll cross that bridge when we get there. -- Source
Would I need to download the complete state every time I open the App and make a payment?
No you'd remember the information from the last time you started the app and only sync the differences. This is not yet implemented, but it shouldn't be too hard to get a preliminary protocol working if that turns out to be a problem. -- Source
What needs to happen for the Lightning Network to be deployed and what can I do as a user to help?
Lightning is based on participants in the network running lightning node software that enables them to interact with other nodes. This does not require being a full bitcoin node, but you will have to run "lnd", "eclair", or one of the other node softwares listed above.
All lightning wallets have node software integrated into them, because that is necessary to create payment channels and conduct payments on the network, but you can also intentionally run lnd or similar for public benefit - e.g. you can hold open payment channels or channels with higher volume, than you need for your own transactions. You would be compensated in modest fees by those who transact across your node with multi-hop payments. -- Source
Is there anyway for someone who isn't a developer to meaningfully contribute?
Sure, you can help write up educational material. You can learn and read more about the tech at You can test the various desktop and mobile apps out there (Lightning Desktop, Zap, Eclair apps). -- Source
Do I need to be a miner to be a Lightning Network node?
No -- Source
Do I need to run a full Bitcoin node to run a lightning node?
lit doesn't depend on having your own full node -- it automatically connects to full nodes on the network. -- Source
LND uses a light client mode, so it doesn't require a full node. The name of the light client it uses is called neutrino
How does the lightning network stop "Cheating" (Someone broadcasting an old transaction)?
Upon opening a channel, the two endpoints first agree on a reserve value, below which the channel balance may not drop. This is to make sure that both endpoints always have some skin in the game as rustyreddit puts it :-)
For a cheat to become worth it, the opponent has to be absolutely sure that you cannot retaliate against him during the timeout. So he has to make sure you never ever get network connectivity during that time. Having someone else also watching for channel closures and notifying you, or releasing a canned retaliation, makes this even harder for the attacker. This is because if he misjudged you being truly offline you can retaliate by grabbing all of its funds. Spotty connections, DDoS, and similar will not provide the attacker the necessary guarantees to make cheating worthwhile. Any form of uncertainty about your online status acts as a deterrent to the other endpoint. -- Source
How many times would someone need to open and close their lightning channels?
You typically want to have more than one channel open at any given time for redundancy's sake. And we imagine open and close will probably be automated for the most part. In fact we already have a feature in LND called autopilot that can automatically open channels for a user.
Frequency will depend whether the funds are needed on-chain or more useful on LN. -- Source
Will the lightning network reduce BTC Liquidity due to "locking-up" funds in channels?
Stack Exchange Answer
Can the Lightning Network work on any other cryptocurrency? How?
Stack Exchange Answer
When setting up a Lightning Network Node are fees set for the entire node, or each channel when opened?
You don't really set up a "node" in the sense that anyone with more than one channel can automatically be a node and route payments. Fees on LN can be set by the node, and can change dynamically on the network. -- Source
Can Lightning routing fees be changed dynamically, without closing channels?
Yes but it has to be implemented in the Lightning software being used. -- Source
How can you make sure that there will be routes with large enough balances to handle transactions?
You won't have to do anything. With autopilot enabled, it'll automatically open and close channels based on the availability of the network. -- Source
How does the Lightning Network stop flooding nodes (DDoS) with micro transactions? Is this even an issue?

My first experience using Lightning Network

I figured it was time to see for myself just how easy or difficult it was to use LN, and no better opportunity than to troll with some memes. I figured if there was a light wallet (Eclair) for android, there'd be something similar for Windows or even Linux to patch through Electrum. Well, after some research, there isn't, at least that I can find. If you want to use LN on desktop, you need a full client which means you need a full Bitcoin Core node.
And apparently, if you want LN to work somewhat decently at all, you need a full client, because out of 100 or more tries to push to payment requests on Eclair for android, only a handful succeeded, as connection to the channel is constantly dropping off an on multiple times a minute, even with a channel opened directly to them.
So I thought I'd try the other mobile LN wallet "Bitcoin Lightning Wallet". After funding it and opening a channel with a large hub, I thought I'd be able to route straight to Unfortunately no, it appears you have to open a channel directly with who you want to transact with on this one as well, and it won't even let me open a channel with SP because "Data loss protection is not provided by this peer".
Needless to say, it's pretty ridiculous in order just to have some fun on this stupid website, I'd have to spin up a Linux box, install a full Bitcoin Core wallet (yay, let me sync for a few days), then install a full LN Daemon on top if it which I'll need to keep online for as long as I have a channel open.
The user experience is no where near at the point of SPV Bitcoin wallets, it barely works at all on the "easy methods".

MoneroV (XMV) | World's Most Private Cryptocurrency

MoneroV (XMV) | World's Most Private Cryptocurrency

MoneroV (XMV) | World's Most Private Cryptocurrency
MoneroV (XMV)
Website :
MoneroV (XMV) is a private, untraceable, finite and secure cryptocurrency fork of the Monero (XMR) blockchain. MoneroV fulfills the long overdue desire for a truly anonymous, decentralized, finite peer-to-peer electronic currency. Individuals and businesses can transact securely, reliably and anonymously with low fees using MoneroV.
MoneroV is truly anonymous and private. Sending and receiving addresses are obfuscated, as well as all amounts being transferred in all transactions. Your identity cannot be linked or traced to a transaction on the MoneroV blockchain.
Roadmap Paper:
Features:Capped: MoneroV adheres to core Austrian school of economics principles by capping the total MoneroV coins that can be created, parting with Monero’s infinite coin supply structure.Secure: Decentralized peer-to-peer blockchain transaction consensus enables MoneroV to be secure and reliable.Private: MoneroV is truly anonymous and private. Sending and receiving addresses are obfuscated, as well as all amounts being transferred in all transactions. Your identity cannot be linked or traced to a transaction on the MoneroV blockchain.
How can I get MoneroV?The only way to obtain XMV is by Trade (buy/sell) at supporting exchange. MoneroV is now listed on Coin Market Cap. You can See the leading exchanges by xmv volume on CMC here.
How MoneroV is different from Monero?MoneroV has a limited supply of coins (27 Million Max) in contrast to Monero’s infinite coin supply. MoneroV will have an active development fund that would be used for rapid development and feature integration versus Monero's voluntary donation based development process. In addition, MoneroV will implement new protocols that will solve the scaling problems facing Monero and other cryptocurrencies such as Bitcoin.
When will the MoneroV wallet be released?The official MoneroV windows wallet is out, in addition to other dependencies such as the MoneroV daemon is released. Macos wallet, Macos and linux miner, Web wallet is in development will be released.
How can I join the MoneroV development team?Anyone can join the MoneroV open source project. We are looking for talented C++ & Node.js developers as well as front-end developers and DevOps engineers.
Additional info is available on our blog:
Supply & Emission:
Specifications Consensus Mechanism: Proof-of-Work Genesis Date: December 16th, 2019 Block Time: 1 minute Max Supply - Capped at 27 Million XMV. Avaliable supply - Current coins supply (total emission) Block Reward: Maximum of 9 XMV per block at the mainnet start and smooth decrease until 27 million max supply will be reached. Proof of Work - Cuckarood29v (based on Cuckoo and CryptoNote) . Difficulty Retarget - Every block. Block Time - Every 1 minutes. Block Size - Dynamic. Privacy - Ring signature / stealth addresses.

(Updated) [Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B


This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:
The updates
If you would like to tip me
Writing a tutorial like this takes time and effort; tips are appreciated. My Reddcoin address: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.





This video shows how long it takes to start Reddcoin Core.   TL;DR:


Backup your wallet to prevent losing the RDDs in your wallet! There are two methods to backup, do both. Make new backups if you create a new receiving address!
Boot with only 1 USB drive plugged in:
Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly.   If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
Connection issues If you have issues syncing the blockchain because you have 0 network connections, please follow the instructions in this thread.
Start Reddcoin Core easier
Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
Minimization options
Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
Chromium as browser: The updates break Firefox, the browser crashes when you try to run it. Install another browser, Chromium, to solve this issue.
Updates / Upgrades
If Software Updater shows up and tells you that there is updated software available, do not install the updates using Software Updater. Use LXTerminal to update Lubuntu.

(Upvote to the top) > SOLUTION FOR ZCLASSIC Eleos Wallet: "Wallet daemon can not be run. Check if daemon does not already run"

So I noticed a lot of people recently (including myself) are experiencing the error "Wallet daemon can not be run. Check if daemon does not already run" when trying to open up their ZCL Eleos wallet, and people are unable to access their funds or cannot export their private keys as well. A solution to this is now official (thanks to JBrutWhat from the BTCP team for helping me out on this.) Note: Post is being edited as more info becomes available to me.
This solution also works for users who are on the ZClassic Swing wallet experiencing the error "A general unexpected critical error has occurred: error: Couldn't connect to server, see the console output for more detailed error information!."
Eleos Wallet Troubleshooting section
ZClassic Electrum Wallet
  1. Create a new standard wallet and restore the 2FA wallet using your "seed" codes. DO NOT password protect this wallet.
  2. Disable the 2FA feature when presented with the option.
  3. Navigate to C:/Users/YOUR-NAME/AppData/Roaming/Electrum-zcl/wallets. Open the new standard wallet file with Notepad.
  4. You will need to gather the 2 private keys and one public key. To find this easily, press “CTRL+F” and search for “xprv”. Copy the 2 “xprv” values as well as the last “xpub” value. You will need these in a later step.
  5. Create a new “Multi-signature wallet”. Select “From 3 co-signers” on the first slider. Select “Require 2 signatures” on the second slider.
  6. To add the first co-signer, click “Use public or private keys”. Enter the first xprv key in this box.
  7. Add the second co-signer via a private key also.
  8. Add the third co-signer with the public key. Complete the set-up.
  9. Your wallet funds now have the ability to be sent from the multi-signature wallet.
For Users who were already using the Electrum wallet beforehand, you can go to file > new/restore wallet > next > import zclassic private keys and input the private key you obtained from the walletaid tool, and it should import the wallet into the electrum wallet. Then from there, go to file > backup wallet and export a copy of the wallet.dat file onto an offline USB.
Reminder: Backup and delete the private keys file from your desktop pc/hard drive, move it into an offline USB for safekeeping. Do not leave it on an online device.

Getting frustrated with Ubuntu. Are my experiences the norm for a Linux user?

Let me start off by saying that I'm not a total newb, but still pretty green. I like to believe I'm capable with computers, and know enough to figure out most issues. I also have a pretty solid general understanding of how they function. Been a Windows user most of my life, but decided to make the switch to Linux a few years back.
My experiences thus far are making me reconsider the switch, despite the fact that I've really become opposed to using Windows. I'm curious if I should expect more of the same indefinitely, or if my experiences up to this point are unusual, and I should expect to reach a point where I can just use the OS, instead of spend hours trying to perform every task.
It all started when I downloaded Ubuntu about three years ago. I easily got it installed as a dual boot on a Windows machine. Had to start by allocating disk space in Windows for the new Linux install, prepared a live usb, went through the install, cake. Then I started trying to do stuff, like use a printer. Well HP doesn't make a driver for Linux and, probably, 2-4 hours of research led to me still not having a working printer. I found a driver, but the process to get it installed did not work as it was supposed to. I forget the specifics, but I followed a tutorial to the T, but ran into unforeseen installation issues, and never could figure out how to get the process complete.
After that I started running into issues with the FireFox browser. I've alwasy used FF on Windows with no issues. On Ubuntu it ran slower than dial-up from the mid-90's. Again, 2-4 hours worth of research and several changes to things like FF settings, disabling add-ons, etc., and I still had no fix.
Still I wasn't deterred. Then the dual boot broke. I tried boot repair. No dice. Tried for several hours to get it working. Asked about it on forums, sent in results of boot repair (where I forget) only to get no response, and finally I threw in the towel.
I also struggled to get Bitcoin Armory working, with some very frustrating success, but I didn't count that against Linux, since it was very new software, and I wasn't surprised it was buggy.
Fast forward to today. I've been using Windows for a couple years, with few attempts made to use Linux, except for trying to retrieve a very small amount of BTC from Armory, which consumed about three weekends of my life to finally achieve.
Now I've decided to give it another go. I downloaded UbuntuStudio b/c I'd like to use some of the music production software that comes with it.
Following some tutorials online, I tried to connect my midi keyboard to the computer using QJackCtl. I couldn't remember the issue that I ran into when starting to type this up, so I tried to repeat the process, only to have the program crash during start up, three times. The computer had literally just restarted 20 minutes ago, so I doubt a reboot would work, but maybe. It's almost funny at this point. I'm really disappointed that I can't get the audio software that came with the distro working "fresh out of the box." Maybe with a few hours, or weekends, worth of research?
I've also been getting a system error message every time I login. I posted a query on the Ubuntu forums. That issue has yet to be sorted out.
I hesitate to include this next part, because it involves software that is really still in it's early stages, and I'm trying to be realistic in taking the perspective that any problems I encounter are with the new software, not Ubuntu, but the fact that I had zero problems getting the same stuff to work in Windows just adds to my frustration with Ubuntu.
Everything I'm about to describe is involved with installing monero mining and wallet software. The exception is the AMD drivers needed for the GPU I'm using to mine. Those I expected to work without issue. I followed the directions for installing the AMD drivers for Ubuntu on the AMD website, and the program would not work. After, you guessed it, 2-4 hours of research, I finally, almost by accident, installed an older version of the driver software. Boom, it worked. WTF man?! When I installed the Windows version it took 2 minutes.
Moving on, I tried getting the xmr-stak mining software working. This took me several hours, spread over several days to sort out. Same with the monero-gui wallet, which actually I've only got half-way working. In fact, I've tried installing the monero-gui by two different ways. In the process I've inadvertently got the monerod daemon running, but not the gui. Actually, the monerod daemon starts with the computer and I haven't even started trying to figure out how to turn that off, since what's the point of having it run if I can't use the gui?
In Windows I had all of this up and running in a couple of hours. And in saying that I'm prepared for the "if you like Windows so much then use that!" or "you're just too thick to figure it out!", but I don't like Windows, and I don't think it's a matter of not figuring it out. It seems to me that the reason I've spent dozens of hours just trying to get things to work in Linux is that nearly every time I've tried to do something, there is inevatably some error along the way where following the directions isn't good enough, and sorting out the issue is a feat in and of itself.
I just want to know if this is unusual, or if this is how it's going to go forever if I keep using Linux. Is my experience typical?
TL;DR: I've had a litany of issues and spent countless hours trying to fix them using Linux. Is this rare, and I've just had an unusual experience, or actually pretty common, and I should just accept it as the cost of using an open source OS?
