Braiins OS+ is autotuning mining firmware that aims to increase hashrate on Antminer S19j Pro, designed to improve efficiency as much as 25%. Braiins is completely reinvented firmware with Open Source code and the all important inclusion of StratumV2. Its 2.8% devfee cost can be negated by pointing the hashrate to Slushpool.
