Skot, founder of Bitaxe (an open-source ASIC-based Bitcoin mining machine), began deconstructing Bitmain's Bitcoin mining machines approximately two years ago. He reverse-engineered one, creating the first-ever open-source ASIC-based Bitcoin mining machine in early 2023.
Bitaxe is technically just open-source code that anyone can use to build a physical mining machine. Anyone can build and sell Bitaxe’s under its open-source license.
The machine runs on a 5 volt power source, uses between 12 and 18 watts of electricity, and connects to the internet through WiFi. Running a Bitaxe full-time should only increase users' energy bill by a few dollars per month.
Bitaxe decentralizes the hashrate, though this will only lead to meaningful decentralization if mining pool centralization declines as well.
Skot created a low-power and affordable Bitcoin miner that anyone can plug in at home, while his work on Bitaxe also paved the way for others interested in open-source Bitcoin mining initiatives.
Skot believes that all aspects of Bitcoin's development should be open source, so that anyone who is remotely interested can get involved.
The Bitaxe and open-source mining movement has taken on a life of its own, and it has become decentralized. Skot stresses that this open-source part is important because Bitcoin mining has forgotten about the open source ethos of Bitcoin, despite this being important.
Out of every Bitaxe sold, approximately $5 is donated to Open Source Miners United (OSMU), which helps financially support both Skot and OSMU grant recipients.
Skot is waiting on the ASIC chip that Jack Dorsey's Block is developing, which will be able to be used in any mining device, and continues to work on open-sourcing the Bitcoin mining stack so that it's easier to compete on the ASIC market.
The broader open-source mining movement has grown and OSMU now has over 4,000 members who share ideas for how to further Bitaxe and the broader open-source mining initiative.
