The date is not yet a finished rollout: developers still need to add the chosen block height to the specification and deliver it in node software. ## Key takeaways - Zcash developers are targeting Nov. 5 for the NU7 mainnet upgrade. - NU7 is designed to reduce Zcash block intervals from 75 seconds to 25 seconds. - The activation height still needs to be merged into the specification. - Node software incorporating the upgrade remains to be shipped. Zcash developers have set Nov. 5 as the target date for activating NU7, an upgrade that would cut the network’s block interval from 75 seconds to 25. Shorter block intervals are intended to make payments confirm more quickly, though they do not guarantee every transaction will be fully settled in exactly 25 seconds. The target activation height has been agreed, but the change is not ready to run on the network yet. Developers still need to merge that height into the specification and ship the corresponding node software. ## What still needs to happen before Zcash NU7 activates? The Nov. 5 date depends on completing those remaining software steps. Node software is what network participants run to follow Zcash’s rules; it must include the upgrade details before the network can activate them as planned. The reports do not describe the date as a completed activation. For users, the practical distinction is between a scheduled target and a live change. Until the software is released and the network reaches its activation point, Zcash payments continue under the existing block schedule. ## What could faster Zcash blocks change for users? Moving from 75-second blocks to 25-second blocks would triple the frequency of new blocks. That can reduce the wait for a payment to appear in a block, but the upgrade announcement alone does not establish how quickly wallets, exchanges, or merchants will treat a payment as final. This is a narrower change than a broad scaling overhaul: NU7’s stated user-facing improvement is faster block production. Zcash had already been discussing a November upgrade focused on payment speed, and the Nov. 5 target turns that plan into a more specific milestone. The earlier plan also mentioned a change to transaction-fee funding, but the current reports here confirm the timing and block interval, not the final status of that separate feature. [Zcash’s earlier NU7 plan](/articles/2026-09-19-zcash-plans-november-upgrade-to-speed-up-private-payments) provides that background. The next concrete milestones are publication of the activation height in the specification and release of compatible node software. Those are the steps to watch before treating Nov. 5 as a confirmed live upgrade. ## FAQ ### When is the Zcash NU7 upgrade expected? Developers are targeting Nov. 5, 2026. The date remains dependent on publishing the activation height in the specification and shipping the necessary node software. ### How will NU7 change Zcash payments? NU7 is designed to reduce the time between Zcash blocks from 75 seconds to 25 seconds, which can make payments appear in a block sooner. It does not guarantee that every service will treat a payment as final within 25 seconds. ### Is the Zcash NU7 upgrade already active? No. The target date and activation height have been agreed, but developers still need to update the specification and release node software before the planned activation. ## Sources This article synthesizes reporting from [CoinDesk](https://www.coindesk.com/markets/2026/10/21/zcash-developers-confirm-november-date-for-upgrade-that-triples-payment-speed), [CoinTelegraph](https://cointelegraph.com/markets/zcash-zec-rallies-12-percent-nu7-mainnet-upgrade?utm_source=rss_feed&utm_medium=rss&utm_campaign=rss_partner_inbound), written by an automated editorial pipeline.
