- + + + + + Verifiable Supply Chain (VSC) — Requirements and Use Cases + + + + + + + + + + + +
+

+ The Verifiable Supply Chain (VSC) specification defines a + framework for interoperable and cryptographically verifiable exchange of + supply chain data. It combines event-based models such as [[EPCIS]] with + decentralized identity technologies including [[DID-CORE]] and + [[VC-DATA-MODEL]]. +

+
+ +
+

+ This document is a Community Group Draft produced by the + Verifiable Supply Chain Community Group. It is not a W3C Standard and may + change at any time. +

+
+ +
+

Introduction

+ +

+ Global supply chains involve multiple independent actors exchanging data + across organizational boundaries. Current systems lack interoperability + and verifiability, resulting in data silos and limited transparency. +

+ +

+ VSC introduces a model where [=Supply Chain Event=]s are represented as + [=Verifiable Credential=]s, enabling secure, interoperable, and auditable + data exchange aligned with [=EPCIS Event=] structures. +

+
+ +
+

+ The key words MUST, + SHOULD, and + MAY are to be interpreted as described in + [[RFC2119]] [[RFC8174]]. +

+
+ +
+

Scope

+ +
    +
  • Verifiable representation of [=Supply Chain Event=]s
    • +
  • Integration with [=EPCIS Event=] data models
    • +
  • Interoperability across organizations
    • +
  • Cryptographic verification of claims
    • +
+ +

This specification does not define:

+
    +
  • Specific blockchain implementations
    • +
  • Business-specific workflows
    • +
+
+ +
+

Terminology

+ +
+
Supply Chain Event
+
An event such as shipping, receiving, or transformation.
+ +
Verifiable Credential
+
A cryptographically verifiable claim per [[VC-DATA-MODEL]].
+ +
EPCIS Event
+
A standardized supply chain event defined by [[EPCIS]].
+
+
+ +
+

Use Cases

+ +
+

Raw Material Provenance

+

+ Enable verification of origin for raw materials using + [=Verifiable Credential=]s derived from [=Supply Chain Event=] data. +

+
+ +
+

Custody Transfer

+

+ Record and verify transfer of goods between participants as + verifiable [=Supply Chain Event=]s. +

+
+ +
+

Compliance Verification

+

+ Provide verifiable proof that goods meet regulatory requirements using + [=Verifiable Credential=]s aligned with [=EPCIS Event=] data. +

+
+
+ +
+

Requirements

+ +
+

Functional Requirements

+
    +
  • Support issuance and verification of [=Verifiable Credential=]s
    • +
  • Enable interoperability across systems
    • +
  • Allow selective disclosure of information
    • +
+
+ +
+

Non-Functional Requirements

+
    +
  • Scalability across global supply chains
    • +
  • Privacy-preserving data exchange
    • +
  • Security against tampering and fraud
    • +
+
+
+ +
+

Security Considerations

+ +

+ Implementations MUST ensure integrity and authenticity of + [=Supply Chain Event=] data using cryptographic verification mechanisms + defined in [[VC-DATA-MODEL]]. +

+ +

+ Privacy SHOULD be preserved using selective disclosure mechanisms + supported by [=Verifiable Credential=]s. +

+
+ +
+

Future Work

+ +
    +
  • Mapping [=EPCIS Event=]s to [=Verifiable Credential=]s
    • +
  • Reference architecture
    • +
  • Interoperability test suites
