Zcash developers ValarDragon and Evan Forbes have proposed reducing the network’s target block interval from 25 seconds to 20 seconds, aiming to shorten the expected wait for initial transaction confirmations without increasing daily private-transaction capacity.
According to Cointelegraph’s report published on November 9, 2026, at 13:36:08 UTC+8, the developers submitted a draft Zcash Improvement Proposal (ZIP) to the community forum on Sunday. They want the proposal included in the next community poll and considered for the upcoming NU7.1 network upgrade. The change remains a proposal, not an activated network update.
Faster confirmations, unchanged issuance
The developers said shorter block intervals would improve the user experience for point-of-sale payments, exchange deposits and cross-chain swaps. The proposal would preserve Zcash’s existing issuance schedule despite more frequent block production, and would not raise the network’s overall daily capacity for private transactions.
Following NU7’s block-time reduction
The proposal followed the NU7 upgrade’s mainnet activation on Friday, which reduced Zcash’s target block interval from 75 seconds to 25 seconds.
NU7 also introduced a Network Sustainability Mechanism designed to recycle a portion of transaction fees into future mining rewards while preserving the supply cap of 21 million ZEC.
