Quick Start#

Mining where multiple miners combine their computational power and share rewards proportionally. Provides consistent, smaller payouts rather than rare large rewards.

Mining independently where you receive the entire block reward if you find a block, but nothing otherwise. High variance but potentially high reward. Solo mining services are often called "pools" even though it's not pooled mining.

The Stratum server address of your mining pool (e.g., stratum+tcp://stratum.braiins.com:3333). This is where purchased hashrate will be directed.

Your unique identifier at the mining pool, typically in the format username.worker_name. Used to track your mining contributions. For solo mining, the username is your BTC wallet address and any rewards will be credited to this address.

A technical parameter in the Stratum protocol. Pools must support extranonce2_size >= 7 for compatibility with Braiins Hashpower's hashrate routing. Most BTC pools meet this requirement. Most non-BTC SHA256 pools (BCH, BSV, etc.) have extranonce2_size=4 and are therefore incompatible.

The computational power used for mining, measured in hashes per second. Common units: TH/s (terahash), PH/s (petahash), EH/s (exahash).

A proof of work submitted by a miner to the pool. Shares demonstrate mining effort and are used to calculate reward distribution. Pools estimate miner hashrate by counting all shares over a given time period. One share equals roughly 2³² hashes.
