Zcash Upgrade Targets Faster Blocks and Post-2031 Security Funding

Zcash developers are proposing a network upgrade that would significantly reduce the time between blocks. Under the plan, Zcash’s block interval would fall from 75 seconds to 25 seconds, making block production three times faster than under the current schedule. The proposal also includes a change to how the network finances its security after 2031. Details of the revised funding approach were not provided in the supplied source material, but the change would affect Zcash’s long-term economic model alongside the faster block cadence. The upgrade therefore combines a technical adjustment with a future change to network funding. The report was published by Decrypt on September 18, 2026. Zcash’s native asset is ZEC.
