Zcash developers confirm November date for upgrade that triples payment speed
Published Updated 10 new reports since it was first published
Zcash developers set Network Upgrade 7 to activate at block 3,543,405, with the change expected around Nov. 5. The upgrade will shorten block times to 25 seconds, while node software and related specifications still need to be finalized and shipped.
What this rests on
What it means
Zcash launched in 2016 as a Bitcoin fork adding zk-SNARK shielded transactions, and its original privacy pool, Sprout, was superseded years ago by the more efficient Sapling design. Block times have sat at 75 seconds since launch, slow next to rivals and even Bitcoin's own confirmation cadence. Network Upgrade 7 is the latest in a line of coordinated hard forks, following prior upgrades that added Sapling and Orchard, and this one finally retires the long-deprecated Sprout pool.
Node operators running the Zcash Foundation's Zebra client must install version 7.0.0 before block 3,543,405 or stop following the chain entirely once NU7 activates. Anyone still holding funds in the old Sprout shielded pool needs to move them before the cutover, since those coins become unspendable afterward. Miners face revised fee-distribution rules, and exchanges or wallets relying on confirmation times will see settlement roughly three times faster, cutting the 75-second wait to 25 seconds.
Shutting down Sprout for good tightens Zcash's privacy guarantees, but it also removes any shielded funds left unmoved, a quiet reminder that 'optional' privacy upgrades still carry forced migration deadlines for users who are not paying attention. The episode sits inside a broader debate over whether faster, more centrally coordinated hard forks on privacy chains trade some of the permissionless ethos for usability gains that keep the network competitive against newer private-payment rails.
The activation point, block 3,543,405, still needs final merging into the specification and shipping in production node software, work the Zcash Foundation flagged alongside sync fixes for Zebra nodes that had stalled near the chain tip. Whether that engineering lands cleanly before the roughly November 5 target will determine if NU7 goes live on schedule or needs a delay, and whether miners and exchanges adapt fee and confirmation logic in time.
