What it does

Financial transaction audit with ZeqProof chains. Every transaction cryptographically linked to the exact Zeqond — immutable, verifiable, tamper-evident.

Signature

Request

POST /api/finance/audit/record

Param	Type	Required	Default	Description
transactionId	string	✓	—	Transaction identifier.
amount	number	✓	—	Transaction amount.
parties	array	✓	—	Array of party ZIDs involved.

Response

{ auditRecord, zeqProof, zeqond, chainPosition, previousProof, verified }

Runnable example

curl -sS -X POST \
  -H "Authorization: Bearer $ZEQ_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "transactionId": "<value>",
  "amount": 0,
  "parties": []
}' \

Integrate

1. Domain solver — compose with KO42 + two additional operators from the matching family for pulse-coherent results.
2. Digital twin — pipe sensor data into this protocol every Zeqond to keep the model phase-locked with the system.
3. Alert threshold — flag results whose error_pct exceeds 0.1% as out-of-spec events for the operations layer.

Seeds

• Near — wrap /api/finance/audit/record in a language SDK so builders can call it in three lines.
• Medium — publish a reference integration demonstrating ZeqAuditFin — Financial Audit Trail alongside a real workload, with pulse-aligned metrics.
• Far — propose ZeqAuditFin — Financial Audit Trail as an open reference standard so other runtimes can implement it verbatim against the Zeq paper.
