Zcash developers propose NU7 activation block for November upgrade
Zcash developers agreed at a meeting of Zcash Improvement Proposal editors to set NU7 activation at block 3,543,405, around November 5, CoinDesk reported. Developer Sean Bowe filed the proposal, which cuts block times to 25 seconds from 75 seconds, removes 60% of each block's fees from circulation until miners are repaid around February 2031, and shuts down the Sprout pool.
Only one publisher so far. Another independent outlet or an official source would raise it.

Claims and open questions
What sources claim
- CoinDesk reported that Zcash developer Sean Bowe filed a proposal to activate NU7 at block 3,543,405, a height agreed at a meeting of ZIP editors.
- According to CoinDesk, NU7 reduces the time between blocks to 25 seconds from 75 seconds and pulls 60% of the fees collected in each block out of circulation, with those coins paid back to miners starting around February 2031.
- CoinDesk reported that the proposal had two approvals but had not been merged into the deployment specification as of 08:00 UTC Wednesday, and that node software must also include the chosen height before the upgrade takes effect.
Still unresolved
- When will the activation height be merged into the deployment specification and included in released node software, confirming the November date?
- How many ZEC still held in the Sprout pool will be moved before NU7 makes them unspendable?
