Necessity Is Not Value Capture: The Zcash Lesson
Zcash earned the highest coin-necessity score on our scale, 5,0 out of 5,0, and still finished at 66 out of 100. Net emission of 3,89% with no sink, a burn proposal sized at 0,05% of a single year of issuance, and a lockbox that defers supply instead of retiring it.

Zcash earned the highest coin-necessity score on our scale — 5,0 out of 5,0. The final rating came out at 66 out of 100.
That gap is the entire lesson. We published the full $ZEC tokenomics audit with a data snapshot of 13 August 2026, and the most transferable finding in it has nothing to do with privacy coins.
The maximum score for necessity changed almost nothing
A shielded transaction is impossible without holding ZEC. No wrapper, no alternative gas, no path through the product that skips the coin. On the necessity scale that is the top category, and almost no project reaches it.
Token Product Linkage still landed at 2,78 out of 5,0 — Moderate Linkage. Inside that block the extremes diverge further than for any project we have scored: coin necessity 5,0, value transfer 1,5, supply absorption 1,2.
The block carries 40% of the total weight, and a 70-point ceiling applies in the 2,5–2,99 range. Base score 63,15, bonuses +3, total 66,15. BBB.
Zcash answered "why is the coin needed." It has not answered "what makes it appreciate."
Two questions, and most teams answer only one
The models we audit usually fail the first question. The product runs fine without the token, so utility gets attached afterwards — a governance vote nobody casts, a discount nobody needs, a staking pool that pays in more of the same asset.
Zcash inverts it. Necessity is structural and permanent, and it still delivers a mid-table score, because necessity governs whether anyone has to buy the coin once. Value capture governs what happens to the coin after they do.
Both questions have to be answered by the mechanism, not by the pitch.
Emission sets a hurdle rate, and someone pays it
657 000 ZEC enters the market every year — $325,7m at the snapshot price, 3,89% of circulating supply. Nothing leaves. There is no burn, no buyback and no protocol-level lock-up.
Fees don't close the gap. They're negligible in volume and go entirely to miners, and the network has no paying customers. So development gets funded the only way left open: 20% of every block reward goes to organisations, split 12% to the lockbox and 8% to community grants.
Read that number as a hurdle rate. The price has to rise 3,89% a year for a holder to stand still. Your model produces the same number whether or not you've calculated it — annual emission minus everything absorbed, over circulating supply, is the return your token must earn before a single holder is ahead.
A sink is only real when it's sized against emission
ZIP-235 would burn 60% of every transaction fee. It would be the first supply-absorption mechanism in the project's history. It sits in draft status, alongside ZIP-233, which introduces the protocol-level ability to remove funds irreversibly.
Now the arithmetic. ZIP-317 sets the fee at 0,0001 ZEC for a typical transaction. The network has processed 3,29m shielded transactions across its whole history, which comes to 329 ZEC in cumulative fees — roughly $163k. Against 657 000 ZEC of annual emission that is 0,05% of a single year. Reaching even 1% would take 180 000 transactions a day, against a historical rate near a thousand.
The mechanism is sound. The scale isn't there.
This is the most common flaw we find in models that already include a burn. The burn gets measured against fee revenue, where it looks substantial, instead of against emission, where it decides whether supply grows. Size the sink against the flow it is supposed to offset. If it clears well under a percent, it's a statement of intent, not a mechanism.
Deferred payout is not a lock-up
ZIP-1015 routed 12% of the block reward into a lockbox across 420 000 blocks. The market read it as supply removed from circulation.
The arithmetic says otherwise: 420 000 × 1,5625 × 12% = 78 750 ZEC, exactly the amount ZIP-271 mandated to be paid out in a single tranche. It was released at the NU6.1 upgrade on 24 November 2025 to a 2-of-3 multisig held by the Zcash Foundation, Electric Coin Company and Shielded Labs.
The lockbox defers supply, it doesn't retire it. The second tranche accumulates at 216 ZEC a day, and the procedure for handling it hasn't been approved — ZIP-1016, which describes a coinholder vote with a quorum of 420 000 ZEC, still holds proposal status.
The transferable point sits in your own supply chart. Any line labelled treasury, reserve or ecosystem fund is deferred supply until a rule says when and how it moves. A wallet without a spending rule isn't a lock-up. It's an unlock with no date, and the market can't price it.
Clean supply mechanics don't compensate for a missing sink
The ZEC supply structure is among the cleanest we've audited. Hard cap at 21m, 80,3% issued, and the reward halves every four years. Vesting, cliffs and unlocks don't exist in the model at all. No venture overhang, no discounted allocations, and the Founders' Reward ended in 2020. The schedule verifies block by block and reconciles with actual balances to the zatoshi.
None of that lifted the rating past BBB.
Distribution hygiene removes reasons to mark a model down. It cannot stand in for the mechanism that turns use into demand. Teams spend months negotiating cliff lengths and then ship a model with no sink at all — Zcash is the hard-capped version of the same omission.
What holds the model together, and what it costs
One balance keeps the economics working: 4,37m ZEC are shielded, 25,92% of supply, about $2,17b, and that share is growing faster than 3,89% a year. Demand for the core function is outpacing dilution. Within 16 days of the Ironwood activation holders voluntarily moved 2,79m ZEC out of 3,66m from the sealed Orchard pool — 73%, with no deadline forcing them.
That's a real demand signal, and it is doing the work that a mechanism would normally do. The risk is that it has to keep doing it forever. Reverse the ratio and nothing in the protocol catches the fall.
Most projects have no demand driver that structural. Which is exactly why they need mechanisms instead.
Three questions for your own model
- Can the product be used without the coin? If yes, no amount of utility copy repairs it.
- What is annual net emission after every sink, as a percentage of circulating supply? That's your hurdle rate, and it's the number your investors will compute.
- Which lines of your supply chart have an approved release rule? Everything else is deferred supply, and it will be priced that way.
Zcash scored 66/100 with the best possible answer to the first question. The other two are where the points went.
