SOLUTION
Multi-Party Trust Networks
N-party trust verification without a central arbiter. Extend bilateral settlement to consortium-scale coordination — trade finance, multi-vendor supply chains, and shared infrastructure governance.
THE CHALLENGE
Multi-party environments — trade finance consortiums, shared supply chains, joint infrastructure — need trust verification across N participants without a single central authority that becomes a failure point or trust bottleneck.
THE APPROACH
Each party in a trust network generates HMAC-SHA256 attestations using a deterministic network-level key derivation. Any party can verify any other party's attestations without pre-shared secrets. k-of-N consensus threshold ensures agreement before state transitions. Dynamic membership with quorum-gated proposals. Dispute resolution via majority vote or designated arbiter.
KEY CAPABILITIES
- ▸N-party attestation with deterministic key derivation
- ▸k-of-N threshold consensus
- ▸Dynamic membership with quorum-gated add/remove
- ▸Dispute resolution — majority vote or arbiter
- ▸Conflicting attestation detection
- ▸REST API with 7 endpoints for remote participation
USE CASES
- ▸Trade finance — multi-bank settlement verification
- ▸Consortium supply chains — shared provenance attestation
- ▸Joint infrastructure — multi-operator governance
- ▸Regulatory — cross-party compliance evidence
