Zcash (ZEC) developers have proposed cutting target block times from 25 seconds to 20 seconds.
The proposal builds on ZIP 218, which reduced block intervals from 75 seconds to 25 seconds.
“A big goal of being the ‘cash’ in Zcash, is to improve its usability,” wrote proposal author ValarDragon.
The change aims to reduce waiting times for payments, exchange deposits and cross-chain transactions.
The proposal maintains the existing 2MB block size while reducing shielded action limits by 20%.
Global shielded budgets and Orchard and Ironwood actions would fall from 330 to 264 per block.
The proposal also preserves expected daily issuance by adjusting block rewards, halving intervals and other network parameters.
Developers want the change included in the proposed NU7.1 upgrade, subject to a community poll and approval.
