Zcash news today centres on the activation of the NU7 network upgrade, which went live on mainnet at block 3,543,405 at 02:34 UTC on 6 November 2026. Zcash (ZEC) trades at $1,327.29, up 3.39% over 24 hours, with a market capitalisation of $22.60B.
Block times fall to 25 seconds
NU7 reduces the target block interval from 75 seconds to 25 seconds under ZIP 218. Actual intervals adjust gradually as difficulty recalculates, and early reports from ZecHub and CoinDesk describe block timing as still settling. ZecHub estimates that shielded throughput will rise from about 2.9 to 6.6 transactions per second.
Per-block limits on shielded actions also cut the worst-case daily wallet download from 271 MB to 169 MB, according to JBizNews.
Sprout pool funds become unspendable
The upgrade froze about 12,224 ZEC held in the legacy Sprout pool, worth roughly $15 million according to ZecStats-based reports. Pre-activation reports had cited about 12,226 ZEC, or about $16 million. Version 4 transactions, the only format able to spend Sprout funds, are invalid under ZIP 2003. No recovery mechanism is scheduled, although a future upgrade could restore access.
Fee recycling and supply schedule
NU7 deploys the Network Sustainability Mechanism under ZIP 237. It removes 60% of transaction fees from circulation into a reserve and reissues them through future block rewards, while miners keep 40%. Reports differ on when reissuance begins, citing either "around February 2031" or block 8,939,664.
The per-block subsidy falls from 1.5625 to 0.52083333 ZEC within the current halving period. The 21 million ZEC supply cap is unchanged, and the next halving is projected for late 2028 at block 6,132,390.
Governance and ecosystem updates
The Zcash Community Grants committee said on 3 November that it would no longer pursue a funding change introduced on 29 October. The original plan would have moved roughly 98,000 ZEC toward the NSM. Zcash Foundation's Zebra 7.0.0, released on 22 October, fixed seven security issues ahead of the upgrade, five of them rated high severity. Zodl also released wallet v3.19.0 with NU7 support on 3 November.
Fund flows and recent price action
Grayscale's ZCSH recorded about $10.99 million in outflows on Thursday, 5 November, bringing its weekly net outflow to about $14.77 million at the time of reporting. ZEC fell about 11% toward $1,135 on 3 November amid the grants dispute, then rebounded roughly 9% to 12% on 4 November ahead of activation.
