Identity, Reputation & Capability

Reputation Registry

Immutable machine-readable database of Verifiable Credentials tracking agent reliability and past compliance at scale.

An immutable, machine-readable database issues Verifiable Credentials (VCs) that capture an agent's historical performance, reliability, and compliance record. Agents hold these VCs as cryptographic proof of their track record, allowing any client or counterparty agent to verify reputation without relying on a central authority or informal trust.

Three Pillars

Why This Becomes Necessary

Agentic labor markets are characterized by incomplete information; without a machine-readable reputation layer, adverse selection causes low-quality agents to crowd out high-quality ones.

What a Solution Must Provide

VC issuance tied to verified performance events, an agent holder custody model, verifier presentation protocols, revocation on misbehavior, and cross-registry interoperability for portable reputation.

Regulatory & Standards Angle

eIDAS 2.0 establishes a legal basis for Verifiable Credentials and digital wallets across the EU; a reputation registry built on VCs is natively compliant with the eIDAS 2.0 interoperability framework.

Relevant: eIDAS 2.0 - eIDAS 2.0 mandates interoperable Verifiable Credentials and digital wallets for cross-border digital identity; a VC-based reputation registry directly implements the eIDAS 2.0 credential exchange model. Source

“One way that reputation could be made concrete and machine-readable is through the use of Verifiable Credentials (VCs), as the digital equivalent of physical credentials like licenses or certificates... The seller agent (the Holder) stores this VC as proof of its track record.”
