Cointelegraph reports testnet activation at block 4,465,026 and a planned Nov. 5 mainnet activation. Check Zcash’s own release or upgrade materials for the reported testnet height and the block-time change.
The supplied reports and Zcash Foundation post agree on the testnet height and 25-second target. Check the Foundation’s linked release notes for its own details and timing context.
The Zcash Foundation’s release notes corroborate that NU7 is scheduled for testnet height 4,465,026 and changes the target interval to 25 seconds. The supplied Cointelegraph post reports the activation; check Zcash’s own account for a direct confirmation that it has occurred.
The Zcash Foundation’s release notes and post established the planned testnet height and shorter block interval; the supplied Cointelegraph report says activation occurred. The project’s own account search found no activation post, so check the Zcash community’s block-monitor account for an independent report of the actual testnet activation.
The Foundation’s release notes establish height 4,465,026 as the planned testnet activation, and Cointelegraph plus Zecblock report NU7 live at that height. The evidence answers the activation question; confirm the date context from those reports before wrapping up.
The supplied report and Zecblock’s post say NU7 went live at testnet height 4,465,026, while the Zcash Foundation had previously announced that height as the activation target. The reported activation and height are now established; check whether any part of the supplied claim still needs verification.
