Zcash developer Sean Bowe has submitted a proposal to set the activation height for the network’s NU7 mainnet upgrade at block 3,543,405, which is expected to fall on Nov. 5. The proposed height has already received agreement at a ZIP editors meeting, though the proposal itself has not yet been merged and still needs to be incorporated into the upgrade specification and node software. Under the current plan, NU7 would reduce Zcash’s target block interval from 75 seconds to 25 seconds. It would also temporarily remove 60% of transaction fees from circulation. The upgrade proposal includes another operational change: disabling v4 transactions. That change carries a direct consequence for users with funds still sitting in the Sprout shielded pool. Once the upgrade takes effect, those funds would no longer be spendable, meaning affected holders need to migrate them before activation. The proposal remains pending final integration, but the expected activation date and technical changes are now clearer.

The proposed height has already been agreed to at a ZIP editors meeting. The proposal, however, has not yet been merged and still needs to be included in the upgrade specification and node software.

NU7 plan includes faster block times and fee changes

Under the current proposal, NU7 would cut the target block interval from 75 seconds to 25 seconds. It would also temporarily remove 60% of transaction fees from circulation.

v4 transactions would be disabled

The upgrade would also disable v4 transactions. At that point, funds that remain in the Sprout shielded pool would no longer be spendable, and affected holders would need to migrate those funds in advance.
