[Analysis: 42.6% of Bitcoin Hashrate Concentrated in the U.S., Mining Pool Control Controversy Continues to Escalate] BlockBeats News, June 14 – Despite Bitcoin's network design emphasizing decentralization and censorship resistance, approximately 42.5% of the global hashrate is currently concentrated in the United States, sparking renewed market discussions about the network's censorship resistance. Data shows that publicly listed U.S. mining companies now account for about 31.5% of the global hashrate, with broader statistics suggesting their total influence may be even higher. At the same time, mining pools like Foundry USA have long held the largest global market share, with the hashrate of a single pool at times approaching one-third of the total. Analysts believe the real risk lies not in simple "geographic concentration" but in the concentration at the mining pool level, as mining pools hold critical control over transaction packaging and block template generation. Currently, the top mining pools collectively control over two-thirds of the hashrate, leading to a high concentration of transaction selection authority. The Bitcoin network demonstrated strong adaptability following mining bans in various countries in 2021, when global hashrate sharply declined in the short term but quickly shifted to the U.S., Canada, and other regions, with no long-term damage to network security. Additionally, analysts emphasize that miners can freely switch mining pools, equipment can migrate across borders, and transaction fee incentive mechanisms all serve to some extent to limit the sustainability of potential "systemic censorship." On the technical front, protocols like Stratum V2 are believed to have the potential to reduce mining pools' control over transaction selection, further decentralizing network governance. Bitcoin's decentralization status should be evaluated comprehensively, considering mining pool control, incentive structures, and energy distribution, rather than relying solely on geographic metrics. The current 42.5% U.S. hashrate share should be viewed as a trend signal rather than a definitive conclusion.
