Zcash targets 20-second block times as developers propose another reduction days after NU7 cut confirmation intervals from 75 to 25 seconds

Developers ValarDragon and Evan Forbes submitted a draft ZIP on the Zcash community forum on Sunday, asking for the change to be included in the next community poll and considered for the NU7.1 network upgrade. The proposal says faster blocks would shorten initial confirmation waits, improving point-of-sale payments, exchange deposits and cross-chain swaps. It would not increase daily capacity for private transactions and would preserve the existing issuance schedule. NU7 activated on mainnet on Friday, cutting block intervals from 75 to 25 seconds and adding a Network Sustainability Mechanism that recycles transaction fees into future mining rewards while keeping the 21 million ZEC cap.
