Braiins

Mining pool and open-source miner firmware — one of the oldest operations in Bitcoin mining.

Braiins runs one of the oldest mining pools in Bitcoin and publishes open-source miner firmware that squeezes more efficiency and control out of common ASICs. Together they cover both ends of a miner’s stack: where you point your hashrate and how your machines run.

The open-source firmware is the standout — transparent, tunable and trusted by hobbyists and industrial operators alike. It is squarely a tool for people who actually run machines; if you don’t mine, its relevance is mostly as a sign of how much of Bitcoin’s mining layer is built in the open.
