Mining Centralization Index (with proxy pools)
Shows the Mining Centralization Index (with proxy pools).The Mining Centralization Index shows how centralized Bitcoin mining has been over time.
It’s calculated by summing up the daily hashrate share of the top n pools. Here, the top
two, three, four, five and six pools are shown. A lower index means that Bitcoin mining is
more decentralized, while a higher index means it’s more centralized.
For example, the “top 2 pools” being over 55% means that the top two pools on that day had more than 55% of the network hashrate. And the “top 6 pools” being 90% means that six pools control 90% of the network hashrate.
Note that this version considers the “AntPool & friends” proxy pool group as a single pool. It’s not clear when exactly “AntPool & friends” started, but it’s assumed that the first pools started to join AntPool around Q3 2022. During May 2024, “AntPool & friends” controlled about 40% of the Bitcoin network hashrate.
Pools currently assumed to be part of the “AntPool & friends” group are:
- AntPool
- Poolin
- Braiins
- Ultimus Pool
- Binance Pool
- SecPool
- SigmaPool
- Rawpool
- Luxor
- CloverPool (formerly BTC.com)
- Mining Squared
