Mining Pools Blocks Mined
Total daily blocks mined across the top 14 mining pools, capturing roughly 95% of network hash power production output.
What is it?
Aggregation metric computed as the daily sum of blocks mined by the 14 largest pools (Foundry USA, Antpool, F2Pool, ViaBTC, Binance Pool, and nine others). The total approaches the Bitcoin network theoretical throughput (about 144 blocks per day at a 10-minute average interval), with deviations tied to difficulty variance and uncounted long-tail pools.
How to read
A stable curve around theoretical throughput reflects nominal operation. Sporadic dips indicate slow-block periods (Poisson variance). A sustained downward drift may reveal hash power migrating to uncounted long-tail pools. Cross-reference this series with global hash rate to distinguish network slowdown from pool migration.
Key zones
Theoretical throughput sits around 144 blocks per day. A structural value between 130 and 145 indicates robust top 14 coverage (~95% of hash power). Below 130, either the network is slowed by difficulty lag, or the share outside top 14 has increased. Above 145, fast-block period post difficulty adjustment.
What to observe
Watch coherence with global hash rate: if hash rate climbs strongly but top 14 aggregation stagnates, mid-cap pools are capturing an increasing share. During regulatory pressure events in a jurisdiction (mining ban), the mix between pools shifts quickly and the share absorbed by non-top-14 can jump.
Historical context
In the early years (2010-2014), top 14 concentration was lower with a long tail of mid-cap pools. Post-2018 consolidation (pool failures, economies of scale) brought top 14 coverage to ~95% of hash power. The China mining ban episode (summer 2021) shifted production toward new pools (notably Foundry USA), accentuating North American concentration.
Expert notes
Six pools (antminer, slushpool, kucoin_pool, sigmapool, neptunemining, oc_emc) absent from the top 14 selection typically represent only a marginal fraction of hash power. The top 14 selection captures structurally dominant actors. For an exhaustive view including long-tail pools, cross-reference with the stacked-area decomposition mining-pools-dominance.
Common mistakes to avoid
This metric is not a proxy for the total number of blocks mined on the network - it aggregates only the top 14. Confusing the two leads to underestimating network throughput by a few percent. For total throughput, use the global network counter or the transaction-count metric cross-referenced with block-interval.
