Gemini upgrades Zcash software to sync blocks in 6 hours ahead of faster 25-second block times

Crypto exchange Gemini switched its Zcash software from Zebra to Zakura, reducing sync time from nearly a day to just over six hours. This upgrade prepares Gemini for Zcash's upcoming NU7 mainnet upgrade, which will shorten block times from 75 to 25 seconds, requiring faster transaction processing. The NU7 upgrade is targeted for November 5, though Gemini has not yet tested Zakura under the faster block schedule. This change is important as faster syncing improves deposit and withdrawal reliability for Zcash users on Gemini.

Zcash (ZEC) has a market cap of Rp7,04 trillion and a 24-hour trading volume of Rp787,62 million on Pluang as of Sep 30, 2026, 15:41 WIB. The coin trades at Rp25.030.294 with a 1-day change of -1.82%. The typical hold time for ZEC on Pluang is 107 days, indicating a moderate investor commitment. This context highlights the importance of Gemini's software upgrade for faster syncing ahead of the NU7 mainnet upgrade, which could impact transaction efficiency for ZEC holders.
