Bitcoin's network hashrate reached 1+ Zettahash/second (1,000 exahashes) in January 2026 for the first time, reflecting deployment of newer ASIC miners. A severe US winter storm in February 2026 forced curtailment, with Foundry USA (the largest mining pool) shedding 60% of capacity; overall 455 exahashes went offline at peak.
