  "account": "Zcash is set to launch its NU7 mainnet upgrade in November, targeting an activation date of November 5, according to developers. The upgrade will reduce block times to 25 seconds, maintaining the cryptocurrency's halving schedule. Testnet activation is planned for October 6, with a final decision on the mainnet upgrade to be made on October 20 after assessing the testnet's performance. The mainnet upgrade would eliminate version 4 transactions and incorporate the Network Sustainability Mechanism (NSM), which would maintain Zcash's halving schedule. ZEC holders overwhelmingly supported the proposal, with 98.9% voting to keep halvings and 99.9% approving the faster-block proposal. The upgrade could impact wallets, full nodes, indexers, and block explorers, requiring adjustments. The timing of the upgrade comes amid a recent surge in ZEC's price, with the privacy coin outperforming the broader market.",
