Implementation Details

Checkpoint Committee System ✅

Based on components.md specifications:

• ✅ Periodically aggregates log roots into checkpoints
• ✅ Co-signs with rotating committee using BLS threshold signatures
• ✅ Publishes to gossip network and mirrors
• ✅ Implements time-lock windows and committee rotation
• ✅ HTTP API for committee operations
• ✅ Memory storage implementation
• ✅ Full service with graceful shutdown

BLS Threshold Signature Aggregation ✅

• ✅ Collect partial BLS signatures from committee members
• ✅ Produce Checkpoint{root, epoch, signers, sig}
• ✅ Verify all partials against same root
• ✅ Slash/downgrade equivocators with reputation events
• ✅ Key generation and signing for testing
• ✅ Complete test suite with 100% pass rate

VRF-based Committee Selection ✅

• ✅ VRF proof generation and verification
• ✅ Deterministic committee selection from VRF outputs
• ✅ Committee membership management (current/next)
• ✅ VRF seed management (current epoch based)
• ✅ Sortition algorithm for committee selection
• ✅ Ed25519-based VRF implementation
• ✅ Complete test suite with 100% pass rate

Rules Registry with Time-locks ✅

• ✅ Comprehensive RuleSet structure with scoring weights
• ✅ Vouch budgets per context (general, commerce, hiring)
• ✅ Score caps and decay parameters
• ✅ Committee and network parameters
• ✅ Time-locked proposal execution
• ✅ SHA256 hash commitment system
• ✅ Ed25519 digital signatures

Governance Proposal System ✅

• ✅ Committee governance proposal workflow
• ✅ Multi-signature approval process (threshold-based)
• ✅ Time-locked rule changes with configurable delays
• ✅ Proposal lifecycle management (pending → approved → executed)
• ✅ Committee member validation and authorization
• ✅ Comprehensive proposal storage and retrieval
