Stratum Protocol
A communication protocol that lets cryptocurrency miners connect to mining pools, receive work, and submit proof-of-work results efficiently.
Stratum Protocol is the standard way many cryptocurrency miners communicate with mining pools. Instead of each miner running a full node and searching for blocks independently, the pool sends miners small units of work, such as block header data and target difficulty, over a lightweight network connection. Miners then try different nonces and submit “shares” back to the pool to prove they are contributing hash power. The pool uses those shares to measure each miner’s work and distribute rewards according to its payout rules.
It matters because mining is time-sensitive and bandwidth-efficient communication helps reduce stale work, where a miner keeps hashing on an outdated block after the network has moved on. Stratum replaced older, less efficient methods such as getwork for many mining setups. A practical comparison is a factory line: the mining pool acts like a coordinator assigning tasks, while each mining machine performs rapid calculations and reports completed attempts. Newer versions, such as Stratum V2, aim to improve security, efficiency, and miner control over block construction.
