The Bitcoin Hashrate Just Hit 1 ZH/s — Here’s Why It’s a Huge Deal
The Bitcoin hashrate hit a record 1.1 zetahashes per second (ZH/s)—or 1,105.68 exahashes per second (EH/s)—on April 4, 2025. This peak was recorded at block height 890,915 and is the first time ever that the Bitcoin hashrate crossed the 1 ZH/s barrier in a well-established surge.

The achievement builds on Bitcoin’s history, with the network first reaching 1 EH/s in January 2016. A zetahash, equivalent to 1,000 EH/s, represents ten thousand leaps from that point, showcasing nine years of growth.

As of April 7, 2025, Blockware Solutions pegs the 30-day moving average at 0.845 ZH/s, with occasional spikes crossing over 1 ZH/s, but consistent values being slightly lower.
Bitcoin Hashrate Historic Leap: Miners Drive Network Security to New Heights
The Bitcoin hashrate crossing 1 ZH/s strengthens the network’s defenses, raising the bar for a 51% attack, which requires control of over half the network’s mining power.
The increase in the Bitcoin hashrate is a sign of the growing miner participation globally, with emphasis on increased adoption and decentralization. Despite volatility linked to block discovery and miner activity, the hashrate’s rise tracks Bitcoin’s global position as a leader in relevance.

Jameson Lopp, a Bitcoin analyst, notes that hashrate estimates can vary by over 0.04 ZH/s depending on calculation methods—such as one versus five trailing blocks. Still, experts agree the network’s strength is at an all-time high.
The milestone is also a sign of sustained investment in mining infrastructure, likely motivated by profitability and confidence in the long-term worth of Bitcoin.
As of April 7, 2025, the Bitcoin hashrate continues to fluctuate, with peaks above 1 ZH/s marking a new phase of computational strength. Whether the first crossing occurred in January, March, or April, the trend is clear: Bitcoin’s mining power is growing, solidifying its status as a secure, decentralized network.
