Zcash developers propose 20-second block intervals
6.8 Tech Zcash developers propose reducing block intervals from 25 to 20 seconds for faster confirmations, with no change to issuance or capacity. The proposal is open for community feedback ahead of the NU7.1 upgrade.
Zcash developers have proposed reducing the blockchain’s target block interval from 25 seconds to 20 seconds. This follows the recent NU7 upgrade, which already shortened block times from 75 seconds to 25 seconds. The draft Zcash Improvement Proposal (ZIP), submitted by ValarDragon and Evan Forbes, aims to further decrease transaction confirmation times, improving the user experience for point-of-sale payments, exchange deposits, and cross-chain swaps. Stress tests indicate that the proposed interval maintains low orphan rates. Importantly, the change would not increase the network’s daily capacity for private transactions or alter the existing issuance schedule. The 21 million ZEC supply cap and daily issuance would remain unchanged, with block rewards and time-based parameters adjusted proportionally to maintain network consistency. The proposal is open for community discussion and is intended for consideration in the upcoming NU7.1 upgrade, pending community approval.
