FAQ

Will new devices be supported?

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

Can I use Braiins OS+ with pools other than Braiins Pool?

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

How does the dev fee work?

When you use Braiins OS+, we collect a 2-2.5% dev fee (depending on hardware model) by directing that percentage of your hashing power to our pool. It’s up to you which pool you mine with for the remaining 97.5-98%. Note that the dev fee is never exactly the specified percentage of your total hashing power, as this number is always changing in real-time whenever you are mining. However, it will always remain within a fixed tolerance as described in the License.

How do I get 0% pool fees with Braiins Pool?

If you choose to mine with Braiins 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, Braiins Pool still collects the standard 2% fee at the time of mining, but all of it is sent back to you as the Braiins OS+ bonus with each FPPS reward.

What is the license and how does it work?

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.

How does Braiins OS+ autotuning work?

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

How can I maximize my 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).

How can I use Braiins OS+ Low Power Mode to keep my S19s profitable for longer?

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.

How long does the autotuning process take?

The tuning takes between 2-9 hours to complete, depending on the type of control board, power limit specified and the quality of the chips in your device.

What are the benefits of upgrading to Stratum V2?

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.

Can I still use Stratum V1 or mine with a pool that only supports V1?

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.

How can I find the latest release?

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.

Is a referral program available? How does the referral program work?

Yes we have a Braiins OS+ referral program. For more details please visit the Braiins Partner Program page.
