The mining pool aggregates miners’ delegated hashrate, sends work to their ASICs, accounts for valid mining shares and credits expected subsidy and transaction-fee revenue under FPPS. It owns neither the connected machines nor Bitcoin consensus.
Braiins Pool is a pooled Bitcoin mining service, Braiins is its operator, and Braiins OS is separate firmware. Miners supply computation from their own ASIC hardware; displayed pool hashrate is therefore delegated rather than company-owned and gives no power to change Bitcoin rules.

Marek Palatinus announced Bitcoin.cz Mining Pool in November 2010 and launched it in December. It became Slush Pool in 2016; after taking operations in 2013, Braiins acquired the remaining stake in 2020 and adopted the Braiins Pool name in 2022.

The mining pool or its template provider builds a candidate block and sends mining jobs to workers through Stratum. An ASIC varies nonce, extranonce, time or version bits and searches below a target; only a result below the network target can become a valid Bitcoin block.

A normal mining share meets an easier pool target, continuously proving contributed work without waiting for a rare block. Accepted, rejected and stale shares affect credited work, but a share does not itself enter the blockchain or alter network difficulty.

Braiins Pool uses FPPS: accepted shares earn expected subsidy as if the network produced the average 144 blocks per day, plus a share of a trimmed average of transaction fees. Revenue is steadier than the pool’s actual finds, while the operator carries variance and the payment obligation.

Stratum V1 supplies ordinary mining jobs but lacks modern authenticated encryption. Braiins supports Stratum V2 with endpoint verification and more efficient communication; merely connecting with V2 does not prove that a miner uses job negotiation to build its own block template.

Documentation checked on 2 September 2026 lists a standard 2.5% pool fee. On-chain payouts of at least 0.005 BTC have no payout fee, smaller ones cost 0.0001 BTC, and Lightning payouts are free. The 0% pool-fee offer with Braiins OS is a product condition, not universally free mining. [Braiins Pool — current product page] [Braiins Academy — Rewards & Payouts] [Braiins Pool — Terms and Conditions]
Payout rules are evaluated daily around 09:00 UTC. On-chain limits are 0.0002 to 5 BTC with a 0.005 BTC free threshold; Lightning allows 1 to 500,000 sats. Financial Accounts split rewards and set schedules or thresholds, while invoices, routes and online receivers still constrain Lightning. [Braiins Academy — Rewards & Payouts]
Non-KYC means the pool does not advertise routine identity verification, not that use is anonymous or trustless. Its privacy policy covers account, email, payout address, IP, device, telemetry, hashrate and reward history; balances also remain a claim on Braiins Mining Limited until paid. [Braiins Pool — Privacy Policy]
A useful comparison checks net reward after pool and payout fees, the precise FPPS formula, rejected and stale rates, latency, uptime, minimum payout, account security, incident transparency and template policy. Pool size reduces operational variance, while template concentration and temporary custody remain separate risks.
