Turnstile Audit

Every shielded pool is sealed by a turnstile: value can only enter or leave by crossing into the transparent layer, and a pool can never hold less than zero. That single rule is the only on-chain surface where counterfeit notes would ever show. This page checks it, every pool, every day — and is honest about what the softer signals can and cannot say.

▍Integrity index
live

Weighted composite of the four components on the right. A turnstile breach is the only hard proof and pins the index to zero; the other three are confounded by ordinary behaviour and can only ever lower it into the inconclusive band.

25.4% of Orchard days (386 of 1520) saw deshields of at least 95% of that day's shielding — a pattern that would hide a slow drain, but also describes ordinary exchange churn.

χ² = 23.3 across 1566 daily outflow values (8 df; 15.5 is the 5% line). Fabricated or throttled outflows tend to bunch first digits.
Read this before the numbers
In June 2026 a value-balance flaw in the Orchard proving circuit was disclosed and fixed. Because Orchard hides note values, nobody can say from the outside whether it was exploited before the fix. Counterfeit value would only become visible at the moment it tried to leave the pool — the turnstile check — and the sharpest attack would hide that exit under legitimate inflows. The soft signals below are built to look for that shape. None of them can prove innocence; only the turnstile can prove guilt.

▍Every pool, hard facts

Computed from the node's per-block value pools. Gap should read 0.00 ZEC: inflows minus outflows must equal the balance exactly.

▍Cumulative in versus out

The out line may approach the in line but can never cross it. Switch pools with the chips.

▍Net flow around the disclosure

Daily net flow (7-day mean) with the fix and the public disclosure marked. A drain that started between the two would be the signature of someone who knew.

χ² 23.3 · limit 15.5

Daily Orchard outflow values (1,566 days) against the logarithmic first-digit distribution that natural, multiplicative quantities follow. Throttled or fabricated outflows bunch on a few leading digits. This is a weak test — but a cheap one, and it is free to be clean.

Big exits that coincide with big price moves are the market, not an exploit. Big exits on quiet days are the ones worth a second look.
