Protocol Registry

​

1. TNP - Temporal Navigation Protocol

• Temporal DAG structure and fork detection
• Timeline branching on concurrent operations
• Three-way merge algorithm (O(n log n))
• State machine ((Official → Draft → Experimental → Archived))
• Immutable operation log (ImmutableLog trait)

• Protobuf v3 message types (AddOperation, GetOperation, etc.)
• Serialization format (length-prefixed frames)
• Performance metrics (30 bytes/operation batched)

​

2. VEST - Verified Event Sequence Trust

• SignatureProof and AuditSignature data structures
• Signature chain linking (hash chain)
• Merkle tree proofs (O(log N) proof size)
• Non-repudiation and tamper-evidence guarantees
• Ed25519 signature creation/verification

• Network message types (SignOperation, VerifySignature, QueryAuditTrail, VerifyMerkleProof)
• Serialization format (SignatureProof ~110 bytes, AuditSignature ~146 bytes)
• Performance (200 bytes/signature, 2 MB/sec for 10K/sec)

​

3. FNP - Fork Node Protocol

• LSEQ position encoding (fractional indexing)
• Three-way merge algorithm (deterministic, idempotent, commutative)
• ChaCha20-Poly1305 encryption per operation
• Operation types (InsertOperation, DeleteOperation, MergeOperation)
• State management (Undo/Redo, document hash)
• Determinism guarantees and conflict detection

• InsertOperation and DeleteOperation message types
• MergeRequest/Response messages
• StateSync message (full state catchup)
• LSEQ position serialization (variable-length)
• Batching support (overhead reduction)
• Encryption per operation (Poly1305 MAC)

​

4. WEAVE - P2P Mesh Network

• Latency-Based Causal Broadcast (LCB) algorithm
• Vector clock model and causal ordering
• Multi-underlay routing (WebRTC/QUIC/BLE/TCP)
• Byzantine fault detection and reputation system
• Convergence guarantees (strong eventual consistency)
• Partition handling and recovery
• P99 latency analysis (≤ 11ms default)
• State machine and integration with TNP/FNP/VEST

• BroadcastMessage (with forwarded_by loop detection)
• AcknowledgmentMessage (latency metrics)
• CausalDependencyRequest/Response (missing events)
• RouteUpdateMessage (underlay metrics)
• PeerHandshake (VC exchange, Ed25519)
• PartitionRecoveryRequest/Response
• Multi-underlay framing (WebRTC/QUIC/BLE)
• Byzantine detection signals
