8  Conclusion

EventChain solves the proof-layer blocker that has held back industry-wide provenance. Supply chains need tamper-evidence, attribution, independent verifiability, minimal operational burden, and continuity beyond any single vendor. EventChain delivers all five through portable artifacts, public-standard cryptography, identity-bound signatures, and local verification.

The consequence is concrete: proof exists at the point of creation, survives beyond the platform that produced it, and identifies who attested to what. When a dispute, audit, safety incident, DPP request, or MRB review demands the full history, the evidence is already in the hands of authorised holders.

Production still requires enterprise discipline: identity governance, ERP integration, schema design, contractual frameworks, onboarding, operating controls sits in the application layer above. EventChain keeps the substrate lightweight enough that verification can cross suppliers, operators, regulators, insurers, and downstream holders without making each one a ledger participant.

The cryptographic machinery has moved behind the scenes. Digitization can happen first, and it can apply to any standard.
