Autotuning mining firmware

We currently support Antminer S9, S9i, and S9j models as well as the S17, S17 Pro, S17+, S17e, T17, T17e and T17+.

Yes, we are working to add support for new Antminer and Whatsminer models. Sign Up for email updates here.

Yes, you can mine with any pool, but Slush Pool is the only one that has has a fee discount for miners using Braiins OS+.

If you choose to mine with Slush Pool while using Braiins OS+, you’ll receive a 0% fee rate instead of the standard 2%. Your 100% fee reduction is given as a rebate on the 2% pool fee collected. In other words, Slush Pool still collects the standard 2% fee at the time of mining, but all of it is sent back to you at a scheduled date each month. The rebate is distributed on the first Monday of every month.

The license is an agreement that you can use the product with a set dev fee. It is valid for one month but it renews itself automatically so you don’t need to do anything to continue using Braiins OS+ long-term. Terms of the license, dev fee, and other benefits of Braiins OS+ may be changed or amended from time to time, so please check our website regularly as the renewed license will always be governed by the current version of terms and information published on our website. See the full license.

When you input your desired power consumption in Watts, our proprietary algorithms automatically calibrate the frequencies on each hashing chip to maximize hash rate.

In order to achieve the maximum possible hash rate uplift enabled by Braiins OS+, you will need to increase your power consumption (W).

If you wish to maximize efficiency rather than hash rate, you simply input a lower power limit (W) and Braiins OS+ will automatically maximize the hash rate at the given power level. Generally, the highest efficiency (i.e. the best ratio of TH/s to W) is achieved with low W inputs.

The tuning takes between 2-6 hours to complete, depending on the power limit specified and the quality of the chips in your device. If the frequency and voltage doesn’t change and you cannot see the word “TUNE” in the system log, the tuning has probably ended. A tuning status indicator will be added in the next release.

Stratum V2 prevents hash rate hijacking through a security scheme known as authenticated encryption with associated data (AEAD). That means you don’t have to worry about backdoors in your modems that allow malicious third parties to silently steal your hash rate. Additionally, Stratum V2 makes several improvements in efficiency, bringing down your data bills and enabling new setups and use cases such as header-only mining. Learn more at stratumprotocol.org.

Yes, both Braiins OS and Braiins OS+ are fully backwards compatible with Stratum V1. If you want to use V2 on your machines but your pool doesn’t support it, you can use a V2 -> V1 translation proxy (written in Rust) to do so. It’s available here.

The latest version of Braiins OS+ can be identified by the dates following the prefix, which are formatted as YY-MM for major releases. For example, a release of Braiins OS+ occuring in October 2021 would be named as Braiins OS+ 21.10. Minor releases (e.g. a small bug fix) will be identified sequentially following the YY-MM. For example, the first minor release following the major release above would be named Braiins OS+ 21.10.1. A second minor release would be named Braiins OS+ 21.10.2 and so on. The same version naming scheme is used for Braiins OS releases and for BOSminer+ and BOSminer.
