A November 7 mainnet snapshot puts the historical seed at 99.7% of the reserve, with 1.12 ZEC accumulated under NU7’s fee rules.

Zcash’s new reserve for future block rewards is still overwhelmingly inherited value. About 99.7% of its balance in an early post-NU7 mainnet observation on November 7, 2026, came from previously unclaimed subsidy and fees, leaving just 1.12 ZEC accumulated under the new rules.

At 05:08:38 UTC, the mainnet API for Zakura’s NU7 monitoring dashboard reported a Network Sustainability Mechanism, or NSM, balance of 369.7 ZEC at block 3,547,068. Its status data showed NU7 active.

ZIP 237, the specification governing the reserve, sets the historical seed at 368.58445520 ZEC. Subtracting that seed leaves 1.11895065 ZEC of subsequent accumulation, or about 0.3% of the observed total.

An early mainnet snapshot separates the historical seed from new fee accumulation, then traces the fee path into future block subsidies.

At the observed height, 1.11895065 ZEC had accumulated beyond the seed. Future support depends on fee demand over time.

Zakura observation at 2026-11-07 05:08:38 UTC, height 3547068. Difference follows reported balance and specified accounting, not a separate block-fee audit. This opening snapshot does not forecast traffic or security adequacy. Reissuance is future at block 8939664.

Integer zatoshi: 36970340585 minus 36858445520 = 111895065. Divide by 100000000 for ZEC. Seed share = 36858445520 / 36970340585 = 99.69733829%; labels round to 99.70% and 0.30%. Bar widths use unrounded shares. Flow connectors are schematic, not quantitative.
