Analysis: 42.6% of Bitcoin's hash power is concentrated in the United States, and disputes over mining pool control continue to intensify.

BlockBeats News, June 14 — Although the Bitcoin network design emphasizes decentralization and resistance to censorship, approximately 42.5% of global computing power is currently concentrated in the United States, sparking renewed discussions about the network's censorship resistance.

Data shows that U.S.-listed mining companies account for about 31.5% of global hash rate, while broader statistics suggest their overall influence may be even higher. At the same time, mining pools like Foundry USA have long held the largest share globally, with a single pool’s hash rate once approaching one-third.

Analysts believe that the real risk is not merely "geographical concentration," but the concentration at the mining pool level, as pools hold key control over transaction packaging and block template generation. Currently, the top mining pools collectively control over two-thirds of the hash rate, resulting in highly centralized transaction filtering power.

Since the global mining bans in 2021, the Bitcoin network has demonstrated strong adaptability. During that period, global hash rate sharply declined in the short term but quickly shifted to the U.S., Canada, and other regions, without long-term damage to network security.

Additionally, analysts emphasize that miners can freely switch pools, equipment has cross-border migration capabilities, and transaction fee incentives also limit the sustainability of potential "systemic censorship" to some extent. On the technical side, protocols like Stratum V2 are believed to potentially reduce pools’ control over transaction selection, further decentralizing network governance.

The decentralization status of Bitcoin should be assessed comprehensively through mining pool control, incentive structures, and energy distribution, rather than relying on a single geographic indicator. The current 42.5% hash rate share in the U.S. should be viewed more as a trend signal rather than a definitive conclusion.
