Bitcoin - The Currency of the Internet

A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.

Hardware Bitcoin wallet - a minimal Bitcoin wallet for embedded devices

Hardware Bitcoin wallet is a project which aims to implement a minimal dedicated Bitcoin wallet. Its main difference with every other Bitcoin client/wallet out there is its low resource requirements: the binary is currently 25 kilobytes large, it uses less than 2 kilobytes of RAM and requires only 160 bytes of non-volatile storage per wallet. With such low requirements, I reckon a production device would be smaller, more robust and cheaper than any other Bitcoin wallet.
The wallet stores private keys (actually, it only stores a seed for the deterministic key generator), parses transactions and signs transactions. It essentially doesn't do anything else. This is by design - simpler means a smaller attack surface. Private keys are generated on the device and never leave the device, except when doing a wallet backup. Even then, the seed is only displayed - it is never sent over the serial port. My intention is that physical access to a device is required in order to obtain private keys or to spend anything. As an additional layer of security, wallets can be encrypted. An encrypted wallet offers pseudo-two-factor authentication: in order to spend BTC, you need to know the wallet passphrase and you need to have the hardware Bitcoin wallet.

Bitcoin Trezor: Hardware Bitcoin Wallet (new photo)

We are creating a hardware bitcoin wallet, basically a device that is a secure place to store private keys to your bitcoin addresses. Because all transactions are signed in the device itself, the keys never leave the device and thus cannot be stolen by a virus, malicious code or an attacker.
During the last few sleepless weeks we managed to redesign the board so it's 20% smaller in size than the original design and it also has electronic components just from the top side, so we can make the product casing even thinner. Here are the photos of the board and prototype aluminium casing.
Check our website which contains links to Facebook and Bitcointalk where you can follow us for more updates. Thanks!
PS: Our website will get some love soon, but hardware comes first. :-)

[Idea] A $30 hardware Bitcoin wallet

Idea:
  1. Modify Rockbox open source MP3 player firmware adding Bitcoin tx signing functions to it.
  2. Buy SanDisk Sansa Clip Zip MP3 player for $30 (or something similar).
  3. Install custom firmware.
  4. You have a device which can sign Bitcoin transactions, and it costs only $30.
Benefits of using MP3 player hardware:
  1. SanDisk produces it in high quantities, anybody can buy it, anywhere.
  2. It is relatively cheap.
  3. It has relatively good screen, which can be used to display tx details for better security.
  4. It also works as an MP3 player, so people won't be upset about the need to spend money specifically on Bitcoin wallet
Drawbacks:
  1. I don't know if USB connection it has can be used for fast and convenient signing. (I.e. whether it is customizable enough.)

Secalot, a hardware bitcoin wallet with extra features announcement.

I want to announce a project I've been working on for the last year -- a USB dongle that combines a hardware bitcoin wallet, an openPGP smart card, a U2F authenticator and a OTP generator. It is completely open source with all the code and design files available on GitHub, github.com/secalot. A prototype is ready and the plan is to start a crowdfunding campaign on Indiegogo, and I'm collecting opinions on the device.
From the bitcoin perspective it offers a secure storage of bitcoin keys on a secure microcontroller with hardware crypto, all operations are pin protected and a press of a touch button is required to confirm a transaction. From software side it integrates with the Electrum wallet. Full bip39 hierarchical deterministic wallet is offered.
In addition the device works as an openPGP smart card, U2F authenticator and an OTP generator.
More details are available on the website, secalot.com.
What do you think?

Extracting the Private Key from a TREZOR (hardware bitcoin wallet) with a 70 $ Oscilloscope

tldr; its possible to monitor the power utilization of the device with an o-scope and read the bits of the private key out of the device. This is fixed in the most current firmware.
