- Remove Address field from PartyEndpoint (parties connect to router themselves)
- Update K8s Discovery to only manage PartyID and Role labels
- Add Party registration and SessionEvent protobuf definitions
- Implement PartyRegistry and SessionEventBroadcaster domain logic
- Add RegisterParty and SubscribeSessionEvents gRPC handlers
- Prepare infrastructure for party-driven MPC coordination
This is the first phase of migrating from coordinator-driven to party-driven
architecture following international MPC system design patterns.
Major changes:
- Add TSS core library (pkg/tss) with keygen and signing protocols
- Implement gRPC clients for Server Party service
- Add MPC session endpoints to Account service
- Deploy 3 Server Party instances in docker-compose
- Add MarkPartyReady and StartSession to proto definitions
- Complete integration tests for 2-of-3, 3-of-5, 4-of-7 thresholds
- Add comprehensive documentation (architecture, API, testing, deployment)
Test results:
- 2-of-3: PASSED (keygen 93s, signing 80s)
- 3-of-5: PASSED (keygen 198s, signing 120s)
- 4-of-7: PASSED (keygen 221s, signing 150s)
