#mining-pools

Who actually mines Bitcoin's blocks, served from the public blockchain.com pools feed. The distribution endpoint ranks the mining pools by the blocks they found over a window (24 hours to 10 days), with each pool's share of blocks and its estimated share of the network hash rate (in EH/s). The centralization endpoint turns that into mining-decentralisation metrics — the top pool's share, the top-3 and top-5 share, the Nakamoto coefficient (the fewest pools that together control more than half of the attributed blocks, a headline measure of how centralised mining is), the Herfindahl concentration index, and the share of blocks not attributed to a known pool. The pool endpoint looks up a single pool's blocks, share, rank and estimated hash rate. This is the mining-pool and hash-rate-distribution / centralisation data-cut — distinct from the mempool-snapshot, the aggregate on-chain-metrics and the price-feed APIs in the catalogue. Estimated per-pool hash rate = block share times network hash rate. Live, no key on the upstream, nothing stored.

Live Bitcoin mining and hashrate analytics, built on the open mempool.space dataset — the mining layer, not address or mempool data: the mining-pool dominance ranking by share of blocks mined over a period, the current network hashrate and difficulty plus their history, the history of difficulty adjustments with each retarget's percentage change, and block-reward economics over the last N blocks (total and average reward, fees and transactions).
