Bitcoin’s mining hashrate has moved into a new regime above 1 zettahash per second (ZH/s, 10²¹ hashes per second) and has stayed there for an extended period, marking a fresh phase of record network security and mining activity. CoinWarz data shows the current global Bitcoin hashrate around 1.03 ZH/s, with an all‑time high of about 1.44 ZH/s recorded in September 2025, indicating that the network has not only crossed the 1 ZH/s threshold but has remained well above it on a sustained basis. Other industry dashboards tracking average daily hashrate similarly show the network hovering in the high exahash to low zettahash range, confirming the structural rise in computing power dedicated to Bitcoin mining. Hashrate measures the total computational power miners deploy to secure the Bitcoin network and validate transactions, and is widely treated as a core security and health metric. A sustained level above 1 ZH/s implies that miners have continued to invest in more efficient hardware and new capacity despite cyclic changes in price and halving events, reinforcing the economic commitment behind Bitcoin’s proof‑of‑work model. The higher and more persistent the hashrate, the more expensive it becomes to mount a 51% attack, which in turn underpins confidence among users, exchanges, and institutional participants that the network can resist attacks and continue operating reliably at scale.
