Bitcoin’s network has hit a significant milestone, surpassing 1 zettahash per second (ZH/s) according to data from Luxor’s Hashrate Index. This increase marks a notable shift in the mining landscape as the hashrate has rapidly escalated from below 800 exahashes per second (EH/s) at the beginning of 2025 to this new level, indicating a robust deployment of mining power.
Out of the total hashrate, approximately 30% is generated by publicly listed Bitcoin miners in the United States. This statistic underscores the growing influence and operation of regulated mining entities within the industry. The seven-day moving average offers a more stable view of this growth trend, smoothing out the daily fluctuations that can obscure the overall picture. Although there have been moments where the network briefly touched the 1 ZH/s mark throughout the past calendar year, this is the first time it has maintained a sustained level above this threshold.
Bitcoin first achieved the 1 EH/s milestone in 2016, and the progression to 1 ZH/s represents a staggering increase by a factor of 1,000 over the course of just nine years. This elevated hashrate not only enhances the security of the Bitcoin network—making it more challenging for malicious actors to alter transaction histories—but also pushes miners to prioritize energy efficiency and manage operational costs effectively. Overall, the rise in hashrate reflects both the growing sophistication of Bitcoin mining operations and the ongoing evolution of the cryptocurrency’s ecosystem.
