Braiins Solo.

Braiins Solo is the solo-mining service of Braiins, the company that runs Braiins Pool. In solo mining each miner works on a block of their own: if their machine finds one, they get its reward, and if it never does, they get nothing. Braiins Pool is for miners who want steady payouts instead. Anyone can connect to Braiins Solo, using a Bitcoin address as their name, without an account.

Braiins runs it on CKPool, open-source software for solo mining. Each block’s first transaction pays the reward straight to the address of the miner who found it, apart from a small share that Braiins sends to CKPool’s authors. That reward is separate from the transactions confirmed inside the block. A block found through Braiins Solo carries its own name, not Braiins Pool’s.

Its first block, 938,092, came on 24 February 2026. Braiins said the miner had rented the computing power for about $75 through Braiins Hashpower, the company’s marketplace for mining power, which can send what people buy straight to Braiins Solo.
