The opening days of 2025 have ushered in new heights for Bitcoin’s hashrate. On Jan. 1, the cryptocurrency’s computational power scaled to a range of 808 to 809 EH/s. As of today, this figure has escalated further, now pulsating between 813 to 823 EH/s. This ascent follows the recent difficulty adjustment on Dec. 29, 2024, at block height 876,960, which saw an increase from 108.52 trillion by 1.16%, reaching 109.78 trillion. The network has experienced a series of consecutive difficulty increases since block height 864,864 on Oct. 9.

This increasing challenge hasn’t deterred miners, and as of Jan. 3, 65 distinct mining groups are contributing at least 79.46 kilohash per second (KH/s) or more to the Bitcoin blockchain. However, massive mining pools are flexing far greater computational strength than this baseline. Leading the pack is Foundry USA, boasting an impressive 306.09 exahash per second (EH/s). Antpool follows with 136.38 EH/s, and Viabtc holds a solid position at 112.36 EH/s.

Currently, Foundry USA claims over 37% of the total hashrate, while Antpool contributes 16.7%, and Viabtc accounts for 13.7%. Between those three pools combined, the lot controls 67.4% of the global hashrate. This surge in computational power further coincides with the eve of Bitcoin’s 16th anniversary. On Jan. 3, 2009, Satoshi Nakamoto famously initiated the Genesis block at 1:15 p.m. Eastern Standard Time. Since then, Bitcoin has achieved an extraordinary uptime of 99.9894%, reflecting its enduring reliability and resilience.

Miners play a pivotal role in fortifying Bitcoin’s blockchain, acting as its vigilant guardians. Their relentless computational efforts not only validate transactions but also reinforce the network’s immutability and trustworthiness over time. As mining pools push technological boundaries, they ensure the blockchain remains a secure, decentralized ledger—safeguarding the very foundation upon which Bitcoin’s global utility and resilience depend.

While miners are essential for securing Bitcoin’s blockchain, the concentration of 67.4% of the global hashrate in just three pools has raised concerns about decentralization in 2024. Such consolidation could pose risks to the network’s integrity, potentially enabling coordinated actions that undermine its trustless nature. True decentralization relies on broader distribution, emphasizing the need for vigilance in preserving Bitcoin’s foundational principles.

In 2024, miners explored innovative strategies to decentralize their operations. Open-source projects empowered individuals with accessible ASIC miners, fostering a more distributed network. Additionally, decentralized mining protocols enabled miners to create custom block templates and manage payouts independently of large pools. As 2025 unfolds, it remains to be seen if these efforts will gain further momentum.
