The “21 Bitcoin Computer”, produced by 21 Inc, can be purchased as of today on Amazon.com for $399.99.
21 Inc came out of stealth mode earlier this year when it announced the largest venture funding in crypto history: $116 million, with investment from tech giants Qualcomm and Cisco.
The startup’s precise plans remain somewhat mysterious to this day. The general idea is to bring bitcoin and blockchain technology to the masses through the distribution of interconnected bitcoin-enabled devices.
The computer is the company’s first marketed product. 21 Inc positions the device as a vehicle to purchase digital goods through a constant stream of bitcoins that it mines. The amount would be relatively small: its hashing power is 50 GH/s (1 GH = 1 billion hashes, or encryption calculations). On average, this gets you roughly 10 satoshis (0.0000001 BTC) every 10 minutes, or 144 satoshis ($0.0046) a day, based on the current difficulty.

The 21 Bitcoin Chip’s advertised power efficiency is 0.16 J/GH, which would be near the top in the mining industry.
The computer also integrates with the “21 Micropayments Server”, where you can sell your digital goods for bitcoin. It would allow developers to build “bitcoin-payable” apps, services and devices.
The computer can operate as a stand-alone device or connect to Mac, Windows or Linux machines. The device itself works off a Linux-based command line interface and includes a Python 3 library.
It also comes with a 128 GB SD card loaded with a full copy of the Bitcoin blockchain ledger, as well as miscellaneous accessories.
