Zcash Developers Select November 5 Target for NU7 Upgrade with 25-Second Blocks
The upgrade will cut block times to 25 seconds and temporarily divert 60% of fees, while Sprout coins left behind become unspendable.
- Zcash developers agreed on block 3,543,405 as the activation point for NU7, the privacy blockchain's major upgrade expected around Nov. 5.
- NU7 introduces significant protocol changes, including Sprout's shutdown and implementation of a Network Sustainability Mechanism that removes 60% of transaction fees from circulation.
- During September's governance poll, approximately 99.9% of participating ZEC supported the 25-second block time reduction, with approximately 98.9% backing preservation of the existing halving schedule.
- Faster block times will significantly reduce transaction latency; three confirmations will take approximately 75 seconds under the new target, compared with 225 seconds currently.
- Under the Network Sustainability Mechanism, fees collected during NU7 operation will be reissued at block 8,939,664 in February 2031, preserving long-term network incentives.
