## Source summary

CoinDesk reports that Zcash engineering groups are targeting November 5 for NU7, which would reduce target block spacing from 75 seconds to 25 seconds and begin a network-sustainability mechanism that temporarily removes 60% of transaction fees from circulation. The community timeline schedules testnet activation for October 6 and a final mainnet activation decision for October 20; the relevant ZIPs remain drafts.

## Why it matters

Shorter block spacing could reduce the wait for confirmations in direct private payments and bridge or exchange flows, but it does not triple total payment capacity and it remains slower than card tap-to-pay at the point of sale. The November date is a target, not a completed launch; code, testnet results and the October 20 decision remain pending, and no merchant adoption, cross-border volume, fee saving or reliability outcome has been measured.

## Key numbers

- **Proposed target block spacing:** 25 seconds (from 75 seconds)
- **Planned testnet activation:** October 6, 2026
- **Target mainnet activation:** November 5, 2026
