Zcash’s NU7 network upgrade activated at mainnet block 3,543,405 in early November, cutting the target block interval from 75 seconds to 25 seconds and introducing the Network Sustainability Mechanism, or NSM, a public reserve for future miner subsidies. At block 3,547,068 on November 7, the NSM held 369.70340585 ZEC, according to Zakura’s mainnet API, with NU7 active and all three configured validators agreeing. ZIP 237’s historical seed was 368.58445520 ZEC, so only 1.11895065 ZEC had accumulated under the new rules; the seed represented 99.69733829% of the balance, rounded to 99.70%, while new accumulation represented 0.30%. Under ZIPs 235, 237 and 259, 60% of aggregate transaction fees are directed to the NSM and 40% remains with miners, with reissuance beginning at block 8,939,664. NU7 also scales scheduled rewards and adjusts remaining issuance and halving intervals so shorter block times do not mechanically triple coin issuance, requires compatible node software and retires support for version-four transactions tied to the original Sprout pool. The snapshot does not forecast future fee demand, usage or security-budget adequacy.
