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.
The distinction matters for Zcash’s future security funding. NU7 has established a way to recycle transaction fees into later block subsidies. Its opening accumulation provides an early measure of contributions; assessing future security support requires a much longer record of fee demand.
