The Bitcoin network hashrate has surpassed 1 Zetahash per second (ZH/s) for the first time in the history of Bitcoin, as reported by several blockchain data sources. This milestone was achieved on April 5, with a peak of 1.025 ZH/s according to mempool.space data. BTC Frame data also confirmed the hashrate hitting 1.02 ZH/s a day earlier. Coinwarz data shows a surge in Bitcoin hashrate to 1.1 ZH/s on April 4 at block height 890,915, but it indicates that Bitcoin initially crossed 1 ZH/s on March 24. Discrepancies in Bitcoin hashrate trackers stem from different calculation methods, block times, difficulty adjustments, and data sources. This achievement underscores the significant computational power and decentralization of the Bitcoin network, enhancing security and reducing the risk of a 51% attack. The reported rise to 1 ZH/s, equivalent to 1,000 Exahashes per second, signifies a 1,000x increase since late January 2016 when Bitcoin first reached 1 EH/s. Litecoin, the second-largest proof-of-work crypto network, currently holds a hashrate of 2.49 Petahashes per second, making it much less powerful than Bitcoin. The surge in Bitcoin hashrate aligns with the increased competition among commercial mining firms. MARA Holdings leads with over 50 EH/s of compute power, while Foundry USA Pool and AntPool dominate the Bitcoin mining pools. Despite Bitcoin’s plummet in value to $78,750 amid market downturns, the new all-time high in hashrate is a remarkable achievement. The market decline is attributed to US President Donald Trump’s tariff plans, heightening recession fears. The rise in Bitcoin hashrate illustrates the resilience and growth of the cryptocurrency ecosystem amidst economic uncertainties.
