Inherited-Quorum Retroactive Verdict Record
One BFT signature authorizes thousands of individually-verifiable findings via Merkle-commitment inheritance. Per-finding court-admissibility at batch-signing cost.
Independent Claim 51.1
A method for producing scalable cryptographic attestation records, comprising: receiving a batch of N payment or settlement records for retroactive audit; executing an audit engine against the batch to produce audit findings; generating a parent attestation record comprising (i) a cryptographic hash commitment over the batch, (ii) a count of findings, (iii) a BFT quorum signature from a threshold of distributed Sovereign Compliance Network (SCN) validators, and (iv) a timestamped distributed-ledger anchor; and for each individual finding, generating a child attestation record that (a) inherits the parent's BFT quorum signature by Merkle-path reference rather than by re-signing, (b) includes a deterministic identifier linking child to parent, and (c) includes a Merkle-path proof committing the child's content hash within the parent's hash commitment; wherein each child attestation is independently cryptographically verifiable against the parent's quorum signature using only the parent's signature and the child's Merkle-path proof, without SCN validator re-signing per child.
Dependent Claims 51.2 - 51.11
- The method of claim 51.1, wherein N is at least 10,000 and the parent quorum signature is produced exactly once for the entire batch.
- The method of claim 51.1, wherein Child records inherit 14-of-20 SCN validator signatures from the parent via Merkle commitment.
- The method of claim 51.1, wherein Each child record carries a deterministic identifier of the form {scheme}-{batch-id}-{child-index}.
- The method of claim 51.1, wherein Parent batch hash uses SHA-256; Merkle commitment uses SHA-256 with a domain-separation tag.
- The method of claim 51.1, wherein Individual child records can be redacted or sealed independently without invalidating the parent quorum signature.
- The method of claim 51.1, wherein Parent record is stored in an archival tier while child records are stored in a hot-query tier, both cryptographically linked.
- The method of claim 51.1, wherein Batch represents at least four years of historical payment records from an institutional source.
- The method of claim 51.1, wherein Child records are independently queryable, filterable, and paginable while preserving verifiability.
- The method of claim 51.1, wherein Child verification path requires O(log N) hash operations regardless of batch size.
- The method of claim 51.1, wherein Parent attestation is usable as a civil evidentiary artifact covering all N findings.
Novelty Over Prior Art
Merkle trees (Bitcoin 2009, Git 2005) are prior art as data-structure. Signature aggregation (BLS, Schnorr) is prior art. What is novel is the protocol semantics: audit-scale batch attestation where one expensive BFT signature covers N inexpensive child attestations that remain independently verifiable. No prior art in audit/compliance combines per-finding court-admissibility with batch-signing cost.
