Zcash has set a new high in its network hashrate just days after the NU7 upgrade, which slashed block times by a third to 25 seconds. Zcash activated its NU7 upgrade on November 6, 2026, at block 3,543,405.
The hashrate of the Zcash network has jumped 5.8% in 30 days to a new high of 32.62 GSol/s, according to Zecstats. This comes as Zcash developers continue to improve network performance and wallet privacy.
Zcash hashrate refers to the total computing power of all miners on the ZEC network. It is calculated by the current network difficulty, the average block find time set by the cryptocurrency network and/or the effective block find time of the latest blocks.
So what now?
ZEC got 3x faster following the NU7 upgrade, which launched on November 6, with block times down from 75 to 25 seconds, and the Sprout pool retired, marking a new era for Zcash.
Faster blocks mean more room for shielded transactions. NU7 adds per-block limits: 330 Orchard or Ironwood actions, 300 Sapling inputs and outputs, a shared budget of 330 across pools, and no new Sprout JoinSplits. These limits more than double Orchard protocol throughput while reducing the worst-case sync load a spammer can push onto light wallets by about 37%.
NU7 does not raise Zcash's fixed 21 million cap; halvings will now come every 5,040,000 blocks instead of 1,680,000, so the issuance schedule holds at roughly four years per halving. NU7 also starts allocating funds for future mining rewards. Some 60% of aggregate transaction fees will flow into a public reserve that pays later mining rewards.
In what comes next after the NU7 upgrade, Zcash developers have proposed cutting block times in a potential NU7.1 upgrade just days after NU7 went live. The proposal would reduce target block times from 25 to 20 seconds, aiming to speed up transaction confirmations and improve user experience and network latency.
