One event. One order. One portable proof.
- Hash integrity
- SHA-256 of every receipt field. Change one bit anywhere and the hash changes completely.
- Chain seal
- Sealed into the Recognitium chain: deterministic SHA-256 evidence, independently verifiable with standard tools.
- Settlement evidence
- The receipt binds payload, sequence position, timestamp, and chain transition into one verifiable proof.
- Chain link
- Each receipt links to the previous one. Delete or reorder a receipt and the chain breaks.
- Envelope seal
- The entire response is sealed with SHA-256: no key, no signature. Modify any field and the seal breaks.
- Temporal binding
- Timestamp evidence is bound into the receipt. The sequence only moves forward.
