Data: Bitcoin's four major mining pools control over 70% of computing power

In comparison, as of June 23, 2026, Foundry Digital, AntPool, ViaBtc, and F2Pool together controlled more than 70% of the Bitcoin network's computing power, about 31%, 18%, 13%, and 10%, respectively. Foundry Digital is an American mining pool, backed by Digital Currency Group, mainly aimed at large institutions and listed mining companies.

D-Central gave a score of 3 for Nakamoto in the first half of 2026, which means that only 3 mining pools can produce more than half of the blocks. ViaBTC faces stricter regulatory scrutiny in 2026, and some miners have switched to alternative mining pools such as EMCD.
