Two Bitcoin mining pools account for 60% of market share

Bitcoin mining pools Foundry USA and Antpool have collectively mined just under 60% of the blocks in the past 24 hours, CryptoSlate reported. Three years ago, Foundry USA had a 24% share and Antpool had 20%. Currently, each commands approximately 30% of the mining pool market. Foundry USA currently boasts a hashrate of 181 EH/s, while Antpool operates at around 140 EH/s. This concentration in mining power has raised concerns about centralization in Bitcoin mining. Bob Burnett, CEO of BTC mining firm Barefoot Mining, pointed out a recent instance where Antpool mined five out of six consecutive blocks between blocks 850448 and 850453.
