Insert messages into the blockchain through the SDK + 2. Support for offline messages with database storage + + 1. Blockchain Integration + + Create a new transaction type for instant messages and integrate + with the existing GCR system: + +```typescript + // Add to the handlePeerMessage function + private async handlePeerMessage( + ws: WebSocket, + payload: { targetId: string; message: SerializedEncryptedObject + }, + ) { + try { + const senderId = this.getPeerIdByWebSocket(ws) + if (!senderId) { + this.sendError(ws, ImErrorType.REGISTRATION_REQUIRED, + "You must register before sending messages") + return + } + + // Create blockchain transaction for the message + await this.storeMessageOnBlockchain(senderId, + payload.targetId, payload.message) + + const targetPeer = this.peers.get(payload.targetId) + if (!targetPeer) { + // Store as offline message if target is not online + await this.storeOfflineMessage(senderId, + payload.targetId, payload.message) + this.sendError(ws, ImErrorType.PEER_NOT_FOUND, `Target + peer ${payload.targetId} not found - stored as offline message`) + return + } + + // Forward to online peer + targetPeer.ws.send(JSON.stringify({ + type: "message", + payload: { message: payload.message, fromId: senderId + }, + })) + } catch (error) { + console.error("Error handling peer message:", error) + this.sendError(ws, ImErrorType.INTERNAL_ERROR, "Failed to + process message") + } + } + + private async storeMessageOnBlockchain(senderId: string, targetId: + string, message: SerializedEncryptedObject) { + const transaction = new Transaction() + transaction.content = { + type: "instantMessage", + from: Buffer.from(senderId, 'hex'), + to: Buffer.from(targetId, 'hex'), + amount: 0, + data: [JSON.stringify({ message, timestamp: Date.now() }), + null], + gcr_edits: [], + nonce: 0, + timestamp: Date.now(), + transaction_fee: { network_fee: 0, rpc_fee: 0, + additional_fee: 0 }, + } + + // Sign and hash transaction + const signature = + Cryptography.sign(JSON.stringify(transaction.content), + getSharedState.identity.ed25519.privateKey) + transaction.signature = signature as any + transaction.hash = + Hashing.sha256(JSON.stringify(transaction.content)) + + // Add to mempool + await Mempool.addTransaction(transaction) + } +``` + 2. Database Entity for Offline Messages + + Create + /home/tcsenpai/kynesys/node/src/model/entities/OfflineMessages.ts: + +```typescript + import { Column, Entity, PrimaryGeneratedColumn, Index } from + "typeorm" + + @Entity("offline_messages") + export class OfflineMessage { + @PrimaryGeneratedColumn({ type: "integer", name: "id" }) + id: number + + @Index() + @Column("text", { name: "recipient_public_key" }) + recipientPublicKey: string + + @Index() + @Column("text", { name: "sender_public_key" }) + senderPublicKey: string + + @Column("text", { name: "message_hash", unique: true }) + messageHash: string + + @Column("jsonb", { name: "encrypted_content" }) + encryptedContent: SerializedEncryptedObject + + @Column("text", { name: "signature" }) + signature: string + + @Column("bigint", { name: "timestamp" }) + timestamp: bigint + + @Column("text", { name: "status", default: "pending" }) + status: "pending" | "delivered" | "failed" + } + ``` + + 3. Offline Message Storage Methods + + Add these methods to the SignalingServer class: + +```typescript + private async storeOfflineMessage(senderId: string, targetId: + string, message: SerializedEncryptedObject) { + const db = await Datasource.getInstance() + const offlineMessageRepository = + db.getDataSource().getRepository(OfflineMessage) + + const messageHash = Hashing.sha256(JSON.stringify({ senderId, + targetId, message, timestamp: Date.now() })) + + const offlineMessage = offlineMessageRepository.create({ + recipientPublicKey: targetId, + senderPublicKey: senderId, + messageHash, + encryptedContent: message, + signature: "", // Could add signature for integrity + timestamp: BigInt(Date.now()), + status: "pending" + }) + + await offlineMessageRepository.save(offlineMessage) + } + + private async getOfflineMessages(recipientId: string): + Promise { + const db = await Datasource.getInstance() + const offlineMessageRepository = + db.getDataSource().getRepository(OfflineMessage) + + return await offlineMessageRepository.find({ + where: { recipientPublicKey: recipientId, status: "pending" + } + }) + } + + private async deliverOfflineMessages(ws: WebSocket, peerId: string) + { + const offlineMessages = await this.getOfflineMessages(peerId) + + for (const msg of offlineMessages) { + ws.send(JSON.stringify({ + type: "message", + payload: { + message: msg.encryptedContent, + fromId: msg.senderPublicKey, + timestamp: Number(msg.timestamp) + } + })) + + // Mark as delivered + const db = await Datasource.getInstance() + const offlineMessageRepository = + db.getDataSource().getRepository(OfflineMessage) + await offlineMessageRepository.update(msg.id, { status: + "delivered" }) + } + } +``` + + 4. Integration Points + + - Register entity: Add OfflineMessage to entities array in + src/model/datasource.ts + - Handle peer registration: Call deliverOfflineMessages() when a + peer registers + - Transaction type: Add "instantMessage" to supported transaction + types + - Import dependencies: Add necessary imports for Transaction, + Mempool, Cryptography, Hashing, etc. + + This implementation provides both blockchain persistence and + offline message support while following the existing codebase + patterns for transactions, database entities, and message handling. \ No newline at end of

Modified: src/libs/blockchain/routines/Sync.ts Integration points added: 1. mergePeerlist() - Exchange L2PS participation with newly discovered peers Non-blocking broadcast to new peers about local L2PS networks 2. getHigestBlockPeerData() - Discover L2PS participants concurrently Background discovery runs parallel to block discovery 3. requestBlocks() - Sync L2PS mempools alongside block sync Each L2PS network syncs in background, errors don't break blockchain sync Added imports: - discoverL2PSParticipants - syncL2PSWithPeer - exchangeL2PSParticipation Design principles: - All L2PS operations run in background (non-blocking) - L2PS errors never break blockchain sync - Concurrent execution throughout -

NodeCalls**: + +```typescript +const result = await peer.call({ + method: "nodeCall", + params: [{ + message: "getL2PSParticipationById", + data: { l2psUid: "network_123" } + }] +}, true) // true =

Input validation: Nullifier hash parameter (injection prevention) 2. Input validation: Commitment parameter (injection prevention) 3. DoS protection: publicSignals bounds check (MAX_PUBLIC_SIGNALS=1024) 4. Tree persistence: Replace non-existent import()/export() with leaves-based approach **MEDIUM Priority (3 fixes)**: 5. Script validation: File existence checks in generate_test_proof.sh 6. Performance: MerkleTreeManager singleton pattern with lazy initialization 7. Security: Sanitize error responses to prevent information disclosure **LOW Priority (2 fixes)**: 8. Database: SQLite constraint detection with startsWith() for all variants 9. Database: Same fix for applyZkCommitmentAdd **CRITICAL Design Clarification (1 fix)**: 10. Comments: Clarify ZK privacy vs points design (transaction submitter rewards) **Investigation Findings**: - Discovered @zk-kit/incremental-merkle-tree v1.1.0 does NOT have import() or export() methods -

Nullifiers marked with CORRECT values ONLY after all verification passes 4.

Secret Generation: Client or Server? - -**Option A: Server-Generated (Easier UX)** -- ✅ Simpler for users (no secret management upfront) -- ❌ Node knows the secret (trust required) -- ❌ Must securely transmit secret to user -- **Mitigation**: Encrypt with user's public key, use HTTPS, delete immediately - -**Option B: Client-Generated (Better Security)** -- ✅ Node never knows secret (zero trust) -- ✅ User has full control -- ❌ More complex UX (backup before verification) -- **Recommendation**: Support BOTH, let user choose - -### 2. Public Record Handling - -**Option A: Never Create** -- Simply skip creating public identity record -- Cleaner code path - -**Option B: Create and Immediately Delete** -- Create record then delete it -- Maintains audit trail -- **Recommendation**: Option A (simpler, same result) - -### 3. Incentive Points for ZK Identities - -Should `zk_verified_commitment` award points like traditional verification? -- **YES**: Encourages adoption, same as public verification -- **NO**: Different use case, shouldn't incentivize -- **Recommendation**: YES, but track separately for analytics - -## Questions to Resolve - -1. **Secret Encryption**: How to securely return server-generated secret? - - Use user's Demos public key (ed25519/pqc)? - - Require HTTPS endpoint? - - Short-lived token approach? - -2. **Rate Limiting**: Prevent abuse of verification-without-storage - - Same rate limits as traditional verification? - - Cost per commitment transaction? - -3. **Referral System**: How do referrals work without public records? - - Store referrer in commitment metadata? - - Separate referral tracking table? - -4. **Migration**: What about existing public identities? - - Allow users to "convert" to private? - - Create ZK commitment for already-verified identity? - -## Security Considerations - -### Server-Generated Secret -- Must encrypt before sending to user -- Delete from server memory immediately -- Use secure random generation (crypto.randomBytes) -- Log warning if transmitted over non-HTTPS - -### Client-Generated Secret -- User must backup BEFORE verification -- If lost, commitment is useless (cannot create attestations) -- Provide clear UX warnings - -### Verification Reuse -- Can same OAuth proof be used multiple times? -- Should we track used proofs to prevent? -- **Recommendation**: Allow reuse (user might want multiple commitments) - -## Future Enhancements - -1. **Batch Verification**: Verify multiple providers in one transaction -2. **Identity Refresh**: Update commitment with new secret (privacy rotation) -3. **Commitment Groups**: Create multiple commitments for same identity (different contexts) -4. **OAuth in ZK Circuit**: Verify ownership inside ZK proof (advanced, future) - -## References - -- Node implementation: `src/libs/blockchain/gcr/gcr_routines/GCRIdentityRoutines.ts` -- SDK implementation: `../sdks/src/abstraction/Identities.ts` -- ZK SDK: `../sdks/src/encryption/zK/identity/` -- Existing OAuth methods: `addGithubIdentity()`, `addTwitterIdentity()`, etc. -- Memory context: `zk_identity_implementation_phases_3_4_5_complete.md` - -## Next Steps - -1.

Merkle Tree: Unified Global Tree -**Decision**: Single tree for all providers (not per-provider trees) -**Rationale**: -- Larger anonymity set (harder to correlate identities) -- Simpler validator logic (one tree to manage) -- Better privacy guarantees -- Provider differentiation handled in commitment hash itself - -### 3. Proof System: Groth16 -**Decision**: Groth16 over PLONK -**Rationale**: -- Groth16 typically shows lower verification latency than PLONK (often 30-50% faster depending on circuit complexity) -- Smaller proofs (~288 bytes vs ~512 bytes for PLONK) -- Battle-tested in production -- Can use existing Powers of Tau ceremony -- Can migrate to PLONK later if transparency becomes priority - -### 4.

allow dynamic hash generation interval via environment variable. - Modified L2PSProofManager to track affected accounts by count instead of addresses for privacy. - Enhanced L2PSTransactionExecutor to store GCR edits in mempool for batch aggregation and updated affected accounts handling. - Introduced subprocess for non-blocking ZK proof generation in L2PSBatchProver, improving performance. - Added zkProofProcess to handle proof generation in a separate process. - Updated L2PSMempool and L2PSProof entities to store GCR edits and affected accounts count. - Created L2PS_QUICKSTART.md for
