The 21 Bitcoin Computer

  • The 21 Bitcoin Computer is the first computer with native hardware and software support for the Bitcoin protocol
  • It is designed for developers to easily build Bitcoin-payable apps, services and devices
  • Operate it as a standalone computer, or connect it to any Mac, Windows, or Linux machine
  • Has a suite of pre-configured Bitcoin-dependent software, and includes a 128 GB SD card loaded with a full copy of the Blockchain
  • Includes all the items you need to get started – including a WiFI adapter, laptop-to-device cable, Raspberry Pi 2, and power supply

The 21 Bitcoin Computer is the first computer with native hardware and software support for the Bitcoin Protocol.

It allows you to:

  • Buy digital goods and services with a stream of bitcoin mined by a 21 Bitcoin Chip
  • Sell your digital goods and services for bitcoin with the built-in 21 Micropayments Server
  • Easily build bitcoin-payable apps, services, and devices
  • Operate it as a standalone computer, or connect it to any Mac, Windows, or Linux machine
  • Mine small amounts of bitcoin to facilitate development of Bitcoin applications and to purchase digital goods. See “What is the 21 Bitcoin Computer” below for more details

It includes:

  • A command line interface and Python 3 library
  • A 128 GB SD card loaded with a full copy of the Blockchain
  • A suite of pre-configured Bitcoin-dependent software
  • All the items you need to get started – including a WiFi adapter, USB-to-laptop cable, and power supply

The 21 Bitcoin Computer was produced with funding from Qualcomm, Cisco, and Andreessen Horowitz.


The First Bitcoin Computer

Mine Bitcoin on demand with the 21 Bitcoin Computer.
Then buy and sell digital goods and services at the command line.

What is the 21 Bitcoin Computer?

The 21 Bitcoin Computer is the first computer with native hardware and software support for the Bitcoin protocol. That means the hardware to mine a stream of small amounts of bitcoin for development purposes, and the software to make that bitcoin useful for buying and selling digital goods.

Developers use the 21 Bitcoin Computer to quickly add Bitcoin-based monetization to any app, service, or device. Please note: the satoshis you mine provide a source of readily-available bitcoin for application development, but are not intended to be used for investment purposes.

How do you use it?

You can use the 21 Bitcoin Computer with your keyboard and monitor as a standalone Linux box, or plug it in to provide bitcoin over the Internet to any existing Mac, Windows, or Linux machine. Either way, the embedded 21 Bitcoin Chip gives you a stream of mined bitcoin to use at the command line and in your code. Now you can programmatically interact with the Bitcoin network as easily as you can connect to the Internet.

What does it let you create?

The 21 Bitcoin Computer is ideal for buying and selling digital goods and services. You can use it to create bitcoin-payable APIs, set up your own personal digital goods store, pay people to share your content online, or host online games of skill. For example, you can provide translation services for bitcoin, sell your photos online, pay people to share links to your product on social media, or host a game of skill in which your friends win real money.

In terms of physical goods, you can also use the 21 Bitcoin Computer to rent out any Internet-accessible device on a per-use basis. So you can allow people to submit paid print jobs to printers and 3D printers for bitcoin. Or you can set up a smart lock that accepts bitcoin to open a door. Because the 21 Bitcoin Computer is a full computer, you can make essentially any Internet-accessible device Bitcoin-rentable.

Free, as in Free Market

The micropayments server built in to each 21 Bitcoin Computer allows true peer-to-peer commerce. Any buyer can now directly connect with any seller anywhere in the world. As such it’s a tool for both learning Bitcoin, and for becoming an entrepreneur by selling access to your digital goods and services for Bitcoin. If you can code it, you can sell it.

About 21

Describe your product in 3 words.

First Bitcoin Computer

Where did you get the inspiration for your product?

We’re all about the individual entrepreneur. The Internet meant that everyone became a publisher, even if their full time job title wasn’t “reporter”. Bitcoin will similarly mean that everyone becomes an entrepreneur, even if they don’t quit their day job. The 21 Bitcoin Computer is our contribution to this transformation.

What differentiates your product from similar products out there?

The 21 Bitcoin Computer allows anyone to sell anything over the internet for bitcoin just by plugging a device into the wall and typing a few commands. We think that is fairly unique.

Tell us about the best and most challenging parts of the creation process.

It is hard to identify a single most challenging part as this kind of product is just inherently difficult to build. We redefine the concept of a full stack startup as we go all the way down to the silicon layer and build our own chips. As for the best part, we’d be happy if the concepts embodied in this device – including native hardware and software support for the Bitcoin protocol, but extending to the concept of buying and selling digital goods and services for bitcoin – do end up empowering a new generation of entrepreneurs, especially in the developing world.

    Very bare bones and overpriced in my opinion. First things first, though. I really wanted to love this device and had high aspirations for it, but I feel it falls short of its intended goal. After a few weeks there is a persistent rattle with the fan and the box that was sent had the seals broken prior to arrival. Amazon offered a credit for $40 to my account, though this doesn’t really address my concerns since I work in the security field. In its current form, it is little more than an overpriced toy at a pretty steep price. After playing with this a while, I setup a Raspberry Pi with a nice case and a fan that does not rattle at a fraction of the cost using Minera and an AntMiner U3. Use PuTTY to SSH to the device and really learn something in the process using publicly available APIs. If you are technical, you are probably familiar with Adafruit Industries.

    If you really want to learn Bitcoin and spend a little more in the process, I would suggest finding a slightly used or refurbished AntMiner S3+ on Amazon or Ebay and ordering the book, Mastering Bitcoin: Unlocking Digital Cryptocurrencies by Andreas M. Antonopoulos. Granted, you are not going to get rich on the setup you will have a much more solid miner that is built to last. The development environment can easily be setup at little to no cost using VMware and Ubuntu and there is no shortage of information regarding Bitcoin on the Internet.

    The CLI and lack of any physical protection for the Raspberry Pi just gives you the illusion that you are working “under the hood” and being technical.

    If you’re looking for a bitcoin devkit to hack on this is a great device. It’s not quiet, but with wifi it means it can be stashed somewhere else.

    This product lets you play with the blockchain and micro payments in a way you just cannot do with a regular full node.
