99.70% of the G-cash balance was from past unclaimed amounts.

Zcash’s network sustainability mechanism (NSM) balance stood at 369.70340585 ZEC on Nov. 7, according to Zakura API data at mainnet block height 3,547,068, with 99.70% of that total consisting of unclaimed amounts accrued before the new fee-collection rules took effect. A record from block height 3,547,061, taken 3 minutes 50 seconds earlier, showed a balance of 369.69867242 ZEC and matched across three nodes, corroborating the near-term figure though not independently re-verifying the exact 2:08:38 p.m. KST reading. The disclosure matters because it indicates that nearly all of the NSM balance reflects legacy unclaimed fees rather than flows generated under the ZIP 237 framework, which governs the mechanism’s mainnet operation. Traders and ZEC holders should watch subsequent block-level NSM balances to see whether new fee accrual begins to meaningfully change the composition of the pool.
