Braiins

Imagine buying an ASIC, a machine designed specifically to mine Bitcoin. The machine repeatedly performs calculations, looking for a result that allows a new valid block, a batch of transactions, to be added to Bitcoin’s history. Plugging it in is only the beginning: you must configure its work, watch its power use and decide whether to mine alone or with others. Braiins tools address these steps. Braiins OS is firmware, the software running inside the device. Braiins Pool combines miners’ work and distributes rewards. The firmware can be used with another pool; these products are not an inseparable package. [3] [4] [16]

Jan Čapek and Pavel Moravec founded Braiins in 2011, bringing experience in banking IT and embedded programming, where software controls specific hardware. Marek Palatinus, known as Slush, introduced them to Bitcoin. His pool predated the company: he announced his pooled-mining proposal on a forum on 27 November 2010. Braiins did not invent the first pool; it gradually became the team able to keep it running over the long term. [1] [9]

Growth brought more machines and greater demands for security and round-the-clock operation. In the March 2012 breach of hosting company Linode, about 3,000 BTC were stolen from the pool’s wallet. Bitcoin’s security does not, by itself, protect an operator’s account or server. In 2013 Braiins acquired a majority stake and took over all pool development and operations. That gave Palatinus more time for Trezor and SatoshiLabs. [2] [11]

Older articles mention Bitcoin.cz Mining Pool, then Slush Pool, and now Braiins Pool. These were not three separate beginnings. The Slush Pool name arrived in 2016, Braiins bought Palatinus’s remaining stake on 1 September 2020, and the Braiins Pool rebranding followed in 2022. It helps to separate the launch of a service, a change of ownership and a new brand: each happened at a different time. [2] [1]

Firmware controls how the machine’s chips and cooling work. Braiins OS offered an alternative to the manufacturer’s software; its first open-source version appeared in 2018. Around the same time, the team verified overt AsicBoost on the Antminer S9, a way to save some computational work, and proposed BIP 310. That extends Stratum V1 with features such as version rolling. The miner and pool agree which parts of the block’s version field the machine may change; technically, these are selected bits in its header. The header is a compact set of data about the block from which the machine repeatedly calculates a hash, a numerical fingerprint. Changing permitted data lets it try more candidates for a result that meets the mining requirement. These changes affect miners’ work, not Bitcoin’s rules for accepting blocks. [1] [8] [16]

Work assignments and results must travel between the machine and the pool. A protocol defines the rules for that exchange. Braiins worked on Stratum V2 with developer Matt Corallo in 2019; it is an open project with other contributors. Secure connections make it harder to impersonate a pool and steal computing power. A separate part of the protocol lets miners propose their own transaction selection for a block. It requires suitable support at both ends: connecting through V2 alone does not enable it automatically. [6] [15]

A commercial firmware version added autotuning in 2020, seeking suitable settings for individual chips at a chosen power target. The team had introduced its own mining software, BOSminer, in 2019. Tuning may aim for lower energy use rather than maximum output. A machine drawing 3 kW continuously for 24 hours consumes 72 kWh; separate cooling may add more. Compare actual electricity use, fees and stability, not just computing speed. The first version’s openness does not establish today’s licensing terms. [1] [14] [13]

Braiins Manager helps monitor and control multiple machines, Toolbox simplifies batch configuration, and Proxy combines their pool connections. In 2023 the pool moved to Full Pay Per Share (FPPS): accepted proofs of computational work, called shares, earn rewards under a formula that includes new bitcoin and transaction fees. A share is usually not a discovered block, but a result meeting the pool’s easier requirement. These results let the pool estimate how much computational work a miner contributed. Payment under FPPS reduces dependence on the pool’s immediate luck, but miners still rely on its accounting and ability to pay. Lightning Network payouts arrived in 2024, using a network for fast bitcoin payments. [5] [12] [1] [16]

Neither a pool nor firmware guarantees that a machine will pay for itself. Electricity prices, competing miners, bitcoin’s price and operating costs all matter. Check firmware support for the exact model, licensing terms and a way back to the original software. For a pool, examine reward calculations, payout limits and fees. “No pool fee” may have conditions and does not mean an operation has no costs. Lightning payouts also need a compatible wallet and an available payment route. [4] [13] [12]

Start with the problem: configuring one machine, overseeing a farm or choosing how rewards are distributed. Then choose a tool and read its current documentation. Mining Pool, ASIC and Stratum V2 provide useful next steps in the Atlas. Braiins’s story reveals the work between switching on a machine and receiving a reward — and why it helps to know which part is handled by software, which by a service operator and which by Bitcoin’s rules.
