Zcash developers want 20-second blocks just days after major speed upgrade

Zcash developers have proposed cutting block times to 20 seconds, just days after a major upgrade accelerated block production roughly threefold. Early data shows the orphan-block rate holding near pre-upgrade levels despite the faster blocks, encouraging developers to pursue a further reduction. The push follows Zcash's recent network speed upgrade, which has already shortened block intervals substantially. The proposal matters because shorter block times can improve transaction confirmation speeds and network throughput if stability holds. What to watch next is whether orphan rates remain contained as block times fall further, and whether the proposal advances toward implementation.
