Steps to Install Braiins OS


By installing I hereby agree to the License which automatically renews every month and I’m aware that the dev fee will be deducted automatically from my hashing power and that all fee rebates will be applied automatically anytime I am using Braiins OS. See FAQs for more details.

  • ¿Se admitirán nuevos dispositivos?

    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.

  • ¿Cómo funciona la comisión de desarrollo?

    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 pool fee removal 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 every block found.

  • ¿Qué es la licencia y cóasdmo funciona?

    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?

    Para lograr el máximo aumento posible del hashrate habilitado por Braiins OS+, deberá aumentar su consumo de energía (W).

  • ¿Cómo funciona el autoajuste de Braiins OS+?

    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 ASICs profitable for longer?

    Simply set a lower power target in Watts.

  • How long does the autotuning process take?

    The tuning usually takes between 1-9 hours to complete, depending on the type of control board, power limit specified and the quality of the chips in your device.

  • ¿Cuáles son los beneficios de actualizar a Stratum V2?

    Stratum V2 prevents hashrate 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

  • How do I connect to Braiins Pool’s Stratum V2 endpoint?

    Click here to be redirected to the instructions on the Braiins Pool website.

  • ¿Puedo seguir usando Stratum V1 o minar con un pool que solo sea compatible con V1?

    Sí, tanto Braiins OS como Braiins OS+ son totalmente compatibles con Stratum V1. Si desea usar V2 en sus máquinas, pero su pool no lo admite, puede usar un proxy de traducción V2 -> V1 (escrito en Rust) para hacerlo. Está disponible aquí.

  • ¿Cómo puedo encontrar la última versión?

    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.

  • How can I verify the downloaded images?

    To check the authenticity and integrity of the downloaded files, download the following public key here and verify the image signature by GPG.

  • ¿Hay un programa de referidos disponible? ¿Cómo funciona el programa de referidos?
