Zcash developers propose reducing block interval to 20 seconds

November 9: Zcash developers ValarDragon and Evan Forbes submitted a draft Zcash improvement proposal on Sunday, suggesting shortening the target block interval from 25 seconds to 20 seconds and incorporating it into the next round of community voting and discussions for the upcoming NU7.1 network upgrade. The proposal states that this move can shorten the initial transaction confirmation wait time and improve offline payments, exchange deposits, and cross-chain swap experiences.

The developers stated that shortening the block interval will not increase the network's total daily private transaction capacity, nor will it change Zcash's existing issuance schedule. The proposal was published a few days before Zcash's NU7 upgrade went live on mainnet on Friday, which shortened the target block interval from 75 seconds to 25 seconds and introduced a network sustainability mechanism to return part of transaction fees to future mining rewards while maintaining the 21 million ZEC supply cap.
