Zcash cuts block time to 25 seconds on testnet ahead of November mainnet upgrade

Zcash has activated its NU7 upgrade on the public testnet, reducing the targeted block time from 75 seconds to 25 seconds. This change aims to speed up transaction processing, benefiting exchanges, wallets, and merchants by shortening confirmation waits. The upgrade also reallocates 60% of transaction fees to a reserve for future mining rewards and reduces per-block rewards to maintain ZEC's issuance schedule. Additionally, it disables the older Sprout privacy system, requiring users to move funds before the mainnet upgrade planned for November 5. Developers will review testnet results and decide on mainnet activation by October 20.

Zcash's NU7 upgrade speeds block time to 25 seconds, a key change ahead of its mainnet launch. For readers following major cryptocurrencies, here is Pluang's market snapshot as of Oct 05, 2026 12:02 WIB: out of 50 priced cryptos, 29 rose and 20 fell today. Notable movers include MANA at Rp1.836 with a 4.03% decline, XLM at Rp4.000 up 3.98%, and YFI at Rp46.577.221 down 3.50%.
