Zcash developers confirm November date for upgrade that triples payment speed
The NU7 upgrade will cut the time between Zcash blocks to 25 seconds from 75 seconds. The chosen block height still has to be merged into the spec and shipped in node software.
Zcash developers have confirmed the November date for an upgrade that will triple payment speeds on the privacy-focused blockchain. The upgrade, known as NU7, will begin at block 3,543,405, as agreed upon at a recent Zcash Improvement Proposal (ZIP) editors meeting. With this change, block times will decrease from 75 seconds to 25 seconds, potentially cutting confirmation times for deposits from nearly four minutes to around a minute and a quarter.
NU7 also removes 60% of block fees from circulation, which will be returned to miners starting in February 2031. However, any coins remaining in Sprout's original privacy system will become unspendable once NU7 activates. Developers have approved the proposal but it has not yet been merged into the deployment specification, as node software must include the chosen height before the upgrade can take effect.
