According to Ki Young Ju, Bitcoin has entered the zetahash era, indicating the network hashrate has reached the 1 ZH/s range (source: X post by Ki Young Ju dated Oct 22, 2025). The milestone was also highlighted by Documenting Bitcoin in the post referenced by Ju (source: X post by Documenting Bitcoin linked in Ju’s announcement). At zettahash levels, protocol rules imply a higher mining difficulty at the next retarget to maintain ~10-minute blocks, a dynamic traders track for miner-margin pressure (source: Bitcoin.org Developer Guide on Difficulty). For positioning, monitor the estimated difficulty adjustment countdown and miner outflows to exchanges as gauges of potential supply from mining entities (sources: Bitcoin.org Developer Guide for adjustment mechanics; CryptoQuant metrics for miner flows).

According to the source, BTC network hashrate was reported at a record 1.2T while mining difficulty fell by 2.7%, a setup that can materially shift miner economics and near-term order flow.

A downward difficulty adjustment increases expected block production rate at a given hashrate until the next retarget, which can temporarily lift on-chain throughput and fee dynamics.

For trading confirmation and risk management, cross-check real-time hashrate and the latest difficulty epoch data rather than relying on secondary reports.
