Verifiable Credential Supply Chain Provenance

W3C formed a Verifiable Supply Chain Community Group in 2026 to standardize proofs of origin and custody that any party can check without trusting the issuer’s database — the same problem AuthiChain’s Verifiable Credentials already address.

Why AuthiChain

• Every provenance record is a W3C Verifiable Credential 2.0, not a proprietary schema
• Ed25519 signatures verify offline — a partner checks authorship without a network call to AuthiChain
• Apache-2.0 spec with a patent grant, so a partner’s legal team can sign off on implementing a compatible verifier

How it works

Issue a unique identifier per unit, anchor its record on-chain for tamper-evidence, and let anyone verify it with a single scan. Plans start at $49/mo.

FAQ

Do we need to join the W3C group to use this?

No — the AuthiChain protocol already implements VC 2.0 and Ed25519 signing; the community group is standardizing supply-chain-specific profiles on the same base spec.

Can a partner verify without an AuthiChain account?

Yes — the spec, the verifier, and the conformance suite are public. A partner runs the reference verifier or their own VC 2.0-compatible checker directly against the record.
