Federated trust networks

[danielbentes]

Context

The current trust model operates within a single agent system. Multi-party deployments (healthcare data exchange, supply chain coordination, financial compliance) require cross-organization trust federation with privacy-preserving aggregation. (Roadmap Section 4.4)

Objective

Enable cross-organization trust for multi-party agent systems through trust federation protocols, signed attestations, and privacy-preserving evidence sharing.

Tasks

• Design trust federation protocol for exchanging trust scores between organizations
• Define trust attestation format (signed trust assertions with expiry)
• Implement cross-domain evidence sharing with privacy-preserving aggregation
• Implement trust conflict resolution across organizational boundaries
• Implement federated identity resolution for entity matching across systems
• Develop reference architectures for healthcare, supply chain, and financial compliance

Acceptance Criteria

• Trust scores can be exchanged between organizations through the federation protocol
• Trust attestations are cryptographically signed and have configurable expiry
• Cross-domain evidence sharing preserves privacy while enabling aggregation
• Conflicting trust assertions from different organizations are resolved deterministically
• At least one reference architecture is documented end-to-end

Hi! This is a fascinating challenge - cross-organization trust federation for AI agents.

We built a Nostr-based Web of Trust API (https://wot.klabo.world) that might help:

What we provide:

• 52K+ nodes with cryptographically signed trust endorsements (NIP-85)
• Transitive trust computation (depth 1-3)
• Privacy-preserving: only pubkeys and scores, no personal data
• Already integrated with Lightning for any paid verifications
• Sybil detection built-in

For your federated trust case:

• Each organization could run their own WoT node
• Trust attestations are portable across Nostr
• Configurable depth for cross-org trust chains

Our MCP server also makes this easy to integrate:

Would love to chat about how this could fit your architecture!
