Sealed-Proof Zero-Exposure Compliance Proof

Executive Summary

JIL Sovereign's sealed-proof mechanism computes, for every discrete compliance check executed against a body of records, a cryptographic commitment: a hash of the check's identifier, its pass/fail result, and a randomly generated salt. Every per-check commitment in a canon run is aggregated into a Merkle tree, and the resulting root is signed with a quorum or hybrid cryptographic signature as a single "all-pass" (or partial-pass) assertion.

The signed root can be disclosed to any counterparty - a regulator, an insurer, an acquirer in diligence - as proof that the underlying canon of checks was executed and produced the asserted outcome, without disclosing the checks themselves, their individual results, or the records they evaluated. If a specific check's outcome later needs to be proven to a specific party, that one check's identifier, result, and salt can be selectively disclosed together with its Merkle-inclusion proof, without revealing any other check's outcome.

Problem Statement

Proving compliance to an outside party traditionally forces a choice between two unsatisfying options. Full disclosure - handing over the underlying records so a regulator, insurer, or counterparty can inspect them directly - exposes sensitive data well beyond what the specific question required. Narrative attestation - a letter or report stating "we passed these checks" - avoids exposing the data, but gives the reader nothing more than the attesting party's word; there is no independent, mathematical way to verify the assertion without re-running the underlying evaluation from scratch.

Neither option scales well to a canon of hundreds of individual checks, where a counterparty may only need proof of a handful of specific outcomes, not the whole record, and where the attesting party needs a way to prove "nothing here was cherry-picked" without publishing everything.

Why Existing Approaches Are Insufficient

• Full data disclosure: Exposes far more than the specific compliance question required, creating unnecessary risk and often triggering its own regulatory handling obligations.
• Narrative attestation letters (SOC 2, HITRUST-style reports): Trust-based; the reader has no independent way to verify the claim without re-auditing.
• Aggregate scores without per-item structure: A single summary number ("98% pass rate") cannot later be decomposed to prove or disprove any specific check without re-disclosing the whole underlying evaluation.

Technical Architecture

Per-Check Commitment

For each check executed, the system computes commitment = H(check_code || result || salt), where salt is a freshly generated random value unique to that check instance. The salt provides hiding - without it, the commitment reveals nothing about the check code or result - and the hash function provides binding, so the committing party cannot later claim a different result for the same commitment.

Merkle Aggregation and Quorum Signature

All per-check commitments for a given canon run are assembled as leaves of a Merkle tree; the resulting Merkle root is signed with a threshold quorum or hybrid cryptographic signature, producing a single all-pass (or specified partial-pass) assertion covering the entire canon run in one compact, independently verifiable artifact.

Selective Disclosure Verification Flow

Proof of a single check's outcome does not require re-disclosing the rest of the canon run.

A successful verification confirms the specific check's outcome against the signed root without the verifier learning the outcome of any check it was not shown.
