There is a new major release of the Braiins OS open source miner firmware for Bitmain’s most popular S9 series of ASIC miners available now. In fact there are now two different versions available Braiins OS community edition and Braiins OS+ enterprise edition, both available for free, with a different feature set and some specifics we’ll cover in a moment. You can use the new Braiins OS or OS+ to replace the original Bitmain firmware on Antminer S9, S9i and S9j and soon hopefully the newer S17 and T17 models will also be supported along with other devices in the future. Braiins OS is fully open-source and customizable so you can tweak it to fit your needs, it supports AsicBoost, supports Stratum V1 and V2 implementation, uses a custom BOSminer developed from scratch in Rust and provides some extra useful features that can help you tweak your ASIC miners and get more of your hardware. The Braiins OS community edition is completely free and open-source without the need to pay for it or any developer fees, unlike the case with some other custom firmware solutions.

The new Braiins OS+ enterprise edition is built on top of the standard community editions and has some extra features available, most interesting of which are the auto-tuning feature to increase hashrate and the low power mode for maximum efficiency as well as the pre-heat option. The rest is like in the standard edition, but the extra features allow you to tweak even better your performance or energy efficiency, depending on your specific needs. The small catch with the Braiins OS+ enterprise edition is that for the extra features you get you will have to agree to the 2% built-in developer fee, however you will also get a 50% reduction (from 2% to 1%) of the pool fee if you use the miners with Braiins OS+ on the Slush Pool for mining. Thanks to the auto-tuning feature in which algorithms automatically evaluate the optimal frequencies for hashing chip-by-chip, instead of treating the entire machine as one single unit the extra performance you may get from a miner should be much more than the fee that you will need to pay.
