The register
A new service is a rule set and a schema, not a new family — which is why the catalogue grows without the security surface growing with it.
Completeness · 5
Proves an entire population went through a named rule set, without revealing any of it. The flagship: an institution can always show you what it found; this shows you it looked at everything.
Solvency · 4
Built on a Merkle sum tree, so one cent on one account changes the commitment. No individual balance is revealed, and an insolvent book still produces a proof.
Threshold · 3
Proves a ratio sits on the right side of a number without revealing the number. A party that misses the bar has no proof — which is why a borrower discloses by proving the tightest bar it does clear.
Gap · 1
Proves the aggregate difference between exactly two groups, compared within a cohort. A group too small to anonymise is refused rather than reported.

If you can define it as a rule, we can prove it without revealing the data.

Custom services
Where a regulation names its own thresholds we encode them. Where it does not — and most do not — your calibration is bound into the proof.
A new service is a schema and a rule set bound into a signed bundle. The rules a proof was evaluated against are named inside it, so a verifier can see which calibration ran — which matters, because most frameworks set no numeric bright lines and leave the thresholds to the firm and its supervisor.
One day. One proof. You decide what comes next.
