ZEC Inflation Analysis · June 2026 · A capped miner mint with a 12% lockbox brake

Zcash mints new ZEC only through mining — about 162K ZEC over 90 days at 1.5625 ZEC per block. Roughly 80% goes to miners and 8% to community grants, both reaching the market, while 12% (about 19K ZEC) is minted into a protocol lockbox that cannot be spent without a future vote. The framework reads about +0.85% net, against our supply monitor at +1.05% — a gap of 0.20 percentage points, inside tolerance, so no monitor-gap chip ships.

The verdict, in one paragraph

For the 90-day window ending June 22 2026, the MrNasdog Pressure Framework reads ZEC at +0.85% net on the forward view. New supply comes entirely from the block subsidy; the only thing pulling the other way is the lockbox, which absorbs 12% of every block. Our supply monitor reads the realized last-90-day change at +1.05%, a gap of just 0.20 percentage points — well inside tolerance, so no monitor-gap chip ships. Zcash is mildly inflationary on a hard-capped schedule: a fixed 1.5625-ZEC reward, halving roughly every four years, against a 21-million ceiling that is already about 80% mined.

Sell pressure: where new ZEC comes from

Sell #1 — protocol inflation — is the whole story, at about 162K ZEC over the next 90 days. Mining is the only way new ZEC is created. The block subsidy is 1.5625 ZEC, paid roughly every 75 seconds — near 1,152 blocks a day — so the chain mints about 162,000 ZEC across this 90-day window. That subsidy is split by protocol rule: about 80% to miners and 8% to the community-grants committee, both of which reach the open market, plus a 12% lockbox leg tracked on the buy side below. The reward last halved in November 2024 (from 3.125 to 1.5625) and does not halve again until about November 2028, so the last 90 days and the next 90 days mint the same amount.

Sell #2 — vesting unlocks — is zero: Zcash has no investor or team vesting. The original Founders' Reward ran from 2016 to the first halving in November 2020 and has been fully expired for years, so no cliff can hit the market. Sell #3 — Foundation and unscheduled unlocks — is also zero as a flow, though it carries the one overhang worth naming: the deferred dev-fund lockbox, covered below. Sell #4 — long-term locked or bankruptcy — is zero, because no bankruptcy estate or court distribution applies to ZEC.

Buy pressure: where ZEC goes

Buy #4 — new long-term lock — is the only non-zero buy-side row, at about 19K ZEC this window. This is the 12% lockbox leg of the block subsidy: the protocol mints it straight into a reserve that is unspendable until a future governance vote authorizes a disbursement mechanism. Those coins are newly created but held off the market, so the framework counts the gross mint as sell pressure and removes the lockbox portion here. Buy #1 — programmatic buyback — is zero: Zcash has no mechanism that buys ZEC back. Buy #2 — protocol fee burn — is zero: transaction fees are paid to miners, not destroyed (a 60% fee-burn, ZIP-235, has been proposed but is not active). Buy #3 — Foundation buy — is zero: nothing buys ZEC off the open market.

Foundation and overhang

Zcash's one real overhang is the deferred dev-fund lockbox. Since the November 2024 upgrade, 12% of every block has been minted into it, and it has accumulated over 120K ZEC — a balance that keeps growing each block. Critically, those coins are locked at the protocol level: they cannot be spent until coinholders approve a separate disbursement ZIP, and as of now no such mechanism has been ratified. The framework therefore books the ongoing 12% as a buy-side lock and treats the accumulated balance as a tracked, off-market overhang rather than current sell pressure. The trigger is simple: if a future vote ever releases the lockbox, that backlog moves to the sell side at the next refresh. The chain emission and any governance change are re-checked on a roughly bi-weekly walk.

How ZEC compares to other privacy and proof-of-work coins

ZEC belongs to the class of hard-capped, halving-model proof-of-work coins — the Bitcoin template — with a 21-million ceiling and a reward that halves about every four years. That makes its long-run inflation path fall in steps toward zero, unlike an uncapped continuous-emission chain. Among privacy coins specifically, that cap is the dividing line: Monero, the other major privacy coin, runs a permanent tail emission with no cap, so it inflates forever at a small fixed rate, while Zcash will stop issuing once the cap is reached.

What sets Zcash apart from a plain halving coin is the dev-fund split. A pure Bitcoin-style chain sends 100% of the subsidy to miners; Zcash routes 20% of every block to ecosystem funding — 8% to grants and 12% into the lockbox. The lockbox is the unusual part: it is freshly minted supply that is minted-but-frozen, so it counts against the cap yet does not pressure the market until governance acts. That gives ZEC a slightly lower effective inflation than its gross mint implies, with a known, dated risk attached to the locked balance.

What to watch in the next 90 days

Watch the lockbox-disbursement governance: proposals to define how (and whether) the accumulated dev-fund balance is spent would, if ratified, flip that backlog from a buy-side lock to a sell event. Watch the ZIP-235 fee-burn proposal — if a burn of transaction fees were ever activated, it would add the first real buy-side offset Zcash has. Watch the ZCG grants mandate, whose current funding cycle runs to about Nov 2027; a renewal or change would alter the 8% leg. And watch block times, since the chain targets one block every 75 seconds and small variances are what separate the framework's gross mint from the monitor's realized count. The next halving is not until about Nov 2028, well outside this window.

Summary

ZEC is a hard-capped, halving-model proof-of-work coin whose supply grows only through mining. The chain mints about 162K ZEC over 90 days at 1.5625 per block; roughly 88% reaches the market through miners and grants, while a 12% lockbox holds about 19K ZEC off-market until a future vote. That leaves the framework at about +0.85% net, against our supply monitor at +1.05%. Zcash stays mildly inflationary today, with two structural brakes ahead — the 21-million cap and the 2028 halving — and one watch item, the locked dev-fund balance that a future vote could release.
