Zcash Developers Propose 20-Second Blocks Days After Major Upgrade
Developers ValarDragon and Evan Forbes proposed reducing the Zcash target block interval from 25 seconds to 20 seconds, seeking faster transaction confirmations while preserving the existing issuance schedule.
On Friday, the NU7 upgrade activated on the Zcash mainnet, cutting the network target block interval from 75 seconds to 25 seconds.
To improve user experience for point-of-sale payments and cross-chain swaps, the proposal targets faster confirmations; developers stated it will not increase daily capacity for private transactions.
The Network Sustainability Mechanism, introduced with NU7, recycles a portion of transaction fees into future mining rewards while preserving the 21 million ZEC supply cap.
On Sunday, developers submitted a draft Zcash Improvement Proposal to the community forum, seeking inclusion in the next poll amid separate governance debates involving a $124M compromise.
