Zcash developers ValarDragon and Evan Forbes submitted a draft proposal to cut the network’s target block interval from 25 seconds to 20 seconds. They want the change included in the next community poll and considered for the planned NU7.1 upgrade; it has not been approved.
The developers say the shorter interval would reduce the expected wait for initial transaction confirmations, but would not increase overall daily capacity for private transactions or change Zcash’s issuance schedule. The proposal followed the activation of NU7, which cut the target interval from 75 seconds to 25 seconds.
