Winklevoss-owned Gemini switches Zcash software ahead of faster 25-second blocks

Gemini, the crypto exchange owned by the Winklevoss twins, has deployed new Zakura nodes to sync with the Zcash network faster ahead of an upcoming protocol upgrade, per CoinDesk. The new software caught up with the network in just over six hours during Gemini's deployments, compared to close to a day with the exchange's previous software.

The shift reflects preparation for Zcash's move to faster 25-second block times, which the protocol is slated to adopt. Faster blocks improve transaction throughput and reduce confirmation latency, a key selling point for blockchains competing on speed. By upgrading its nodes ahead of the fork, Gemini ensures minimal disruption to its trading and custody operations when the network transitions.

The upgrade underscores growing focus on block time reduction across major cryptocurrencies and exchanges. Faster finality translates to better user experience for traders and smoother operational flows for platforms that hold and move digital assets. Gemini's decision to deploy new software early signals that major exchanges view this technical shift as material enough to warrant advance infrastructure changes.

Node synchronization speed matters operationally for exchanges, which rely on validators to stay current with the chain state and confirm transactions. A six-hour sync instead of a full day means faster recovery after restarts, network issues, or migrations — material for 24/7 trading platforms.
