21 Inc is the creator of the 21 Bitcoin Computer.

21 Bitcoin Computer

21 Inc believes that satoshis–the smallest unit of BTC–will become a system resource used to pay for small tasks across the internet. One project built using the 21’s computer, for example, uses the company’s software to sell API calls for satoshis. Another allows Twitter accounts to sell retweets for satoshis.

The 21 Bitcoin Computer is a computer that comes with a 50 Gh/s mining chip and also operates as a Bitcoin full node. The built-in mining chip provides the computer’s owner with a constant stream of satoshis that can be used to pay for these small tasks.

The 21 Bitcoin Computer is available on Amazon and costs $399.99.
