Zcash developers propose reducing the block interval to 20 seconds.

Mars Finance reports that Zcash developers have proposed reducing the target block interval from 25 seconds to 20 seconds to accelerate transaction confirmation times. On Sunday, developers ValarDragon and Evan Forbes submitted a draft Zcash Improvement Proposal (ZIP) on the Zcash community forum, seeking to include this change in the next community vote and consider it for the upcoming NU7.1 network upgrade. According to the proposal, shortening the block interval would reduce the expected waiting time for initial transaction confirmations, improving user experience for in-person payments, exchange deposits, and cross-chain swaps. The developers noted that this change would not increase the network’s overall daily capacity for privacy transactions; despite more frequent block production, the proposal would maintain Zcash’s existing issuance schedule. The proposal was introduced just days after the NU7 upgrade. On Friday, the NU7 upgrade activated on mainnet, reducing the network’s target block interval from 75 seconds to 25 seconds. This upgrade also introduced a network sustainability mechanism that recycles a portion of transaction fees to fund future mining rewards, while preserving Zcash’s 21 million ZEC supply cap.
