| The stratum protocol was extended to support pooled mining as a replacement for obsolete [[Getwork|getwork]] protocol in late 2012.
| | Main page: [[Stratum mining protocol]] |
| Developed behind closed doors, the mining service specification was initially announced via [[Slush's pool]]'s website<ref>[http://mining.bitcoin.cz/stratum-mining/ Stratum mining protocol specification at slush's pool's website]</ref>.
| |
| Shortly thereafter, alternative "cheat sheet" style documentation was provided by [[BTCGuild]]<ref>[https://www.btcguild.com/new_protocol.php Stratum mining protocol cheat sheet at BTCGuild's website]</ref>.
| |
| As the extension lacks a formal [[BIP]] describing an official standard, it has further developed only by discussion and implementation<ref>[https://bitcointalk.org/?topic=557866 ckolivas's collection of most proposed stratum mining extensions]</ref>.

Stratum is a proposal for an open source client-server "overlay" protocol that enables thin clients.
It is currently used by Electrum.
While originally announced right before 2012[1], the protocol has not yet been completed and proposed as a BIP for standardisation.
