About this source
The mempool.space mining-pools registry is a community-curated JSON of coinbase scriptSig tag patterns plus known reward addresses for every active and historic Bitcoin mining pool. It powers mempool.space's pool-attribution column and is updated as new pools come online or rebrand. We ingest the full pool list (170 entries) and keep the per-pool tag patterns alongside for downstream consumers who want to do their own coinbase decoding.
How we got the data
Pulled from the mempool-org/mining-pools repository at deploy time. Per-pool entry parsed; reward addresses ingested with the pool's display name as label.
Why this confidence
Very high. Mining pools generally announce their addresses publicly and the registry is community-audited. The 0.05 reservation is for the small number of historical pools whose addresses are inferred from coinbase tags rather than directly disclosed.
License & attribution
MIT-licensed public registry. We retain the upstream pool slug in source_ref so changes propagate cleanly through targeted updates.
