What Braiins does
Braiins is a vertically integrated Bitcoin mining software and infrastructure company founded in 2011 in Prague, Czech Republic, operating through Braiins Systems s.r.o. (Czech Republic) and Braiins Mining Limited (British Virgin Islands). The company runs the world's longest-running Bitcoin mining pool — operating since 2010 under the original Slush Pool brand — at 13.91 EH/s of hashrate with 177,359 active workers and 13,112+ active users across 100+ countries, and has mined 1.3M+ BTC all-time. Its product portfolio spans ASIC firmware (Braiins OS open-source and Braiins OS+ proprietary), a cloud-based fleet management platform (Braiins Manager with the Controlflow automation engine), a local batch configuration toolkit (Braiins Toolbox), a hashrate aggregation proxy (Braiins Proxy), a solo mining pool (Braiins Solo), a usage-based hashrate marketplace (Braiins Hashpower), and a hardware experimental lab (Braiins Forge producing the DECK, BCB 100 control board, and BMM 101 Mini Miner). Co-founders Pavel Moravec and Jan Čapek developed the Stratum V2 mining protocol in 2019 alongside Matt Corallo, providing authenticated encryption, 60-70% bandwidth reduction, and miner-controlled transaction selection.
The technology stack is anchored by proprietary firmware optimization: autotuning algorithms assign workload based on per-chip quality, Dynamic Power Scaling manages thermals, and per-chip frequency calibration maximizes hashrate at target power. Quantified and independently verified performance benefits include 10-16% hashrate improvements at equivalent power on Antminer S21 XP hardware, 2.62-12.47% efficiency gains verified by TÜV SÜD, 95% data transfer reduction via hashrate aggregation, and sub-1% power tracking accuracy versus wall measurement. Braiins OS runs on 100,000+ devices representing 2+ GW of infrastructure. Go-to-market combines product-led growth via free downloads (Braiins OS, Toolbox, Proxy), enterprise direct sales for large operations, an active multilingual community (Telegram groups in English, Spanish, Russian, Farsi, Chinese), an annual Bitcoin Mining Conference in Prague, and a referral partner program that pays 20% of dev fee income to partners contributing 50+ PH/s.
Revenue is generated through a 2-2.5% dev fee on Braiins OS+ (collected by directing hashrate to Braiins Pool), a 2% FPPS pool fee on Braiins Pool (rebated to 0% for OS users), hardware sales through a global online marketplace (ASPs $639-$3,365, accepting BTC/USDC/fiat), usage-based hashrate transactions on Braiins Hashpower, and premium support subscriptions for Braiins Manager. The company also raises capital via public corporate bonds (9.5% per annum, 3-year duration) used to fund hardware R&D, with 135M CZK (~USD 6M) issued across 2021-2023. Customer segments include industrial mining operations (primary), mining hosting providers, and individual/small-scale miners; named enterprise customers include MARA Holdings, American BTC, Mawson, Giga Energy, BMA Enterprises, and Barefoot Mining.
