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

@@ +# DTR (Distributed Transaction Routing) + +## Overview + +**DTR (Distributed Transaction Routing)** is a production-ready enhancement to the Demos Network that optimizes transaction processing by intelligently routing transactions based on node validator status. Instead of every node storing every transaction in their local mempool, DTR ensures that only validator nodes maintain transaction pools, while non-validator nodes act as efficient relay points. + +## Problem Statement + +In traditional blockchain networks, including the base Demos implementation, every node maintains a full mempool regardless of their validator status. This approach leads to several inefficiencies: + +- **Resource Waste**: Non-validator nodes store transactions they will never process +- **Network Redundancy**: Identical transactions are stored across hundreds of nodes +- **Consensus Complexity**: Validators must sync mempools from numerous non-validator nodes +- **Memory Overhead**: Each node allocates significant memory for transaction storage + +## DTR Solution + +DTR implements a **two-tier transaction architecture**: + +### **Tier 1: Validator Nodes** +- Maintain full transaction mempools +- Process and include transactions in blocks +- Receive transactions from non-validator nodes via relay + +### **Tier 2: Non-Validator Nodes** +- Act as transaction relay points +- Forward transactions to validator nodes immediately +- Maintain minimal local cache only for retry scenarios +- Continuously attempt to relay failed transactions + +## Security Advantages + +### **1. Reduced Attack Surface** +- **Mempool Attacks**: Only validator nodes maintain full mempools, reducing targets for mempool flooding +- **Storage DoS**: Non-validators cannot be overwhelmed with transaction storage attacks +- **Network Efficiency**: Eliminates redundant transaction storage across the network + +### **2. Enhanced Validation Security** +- **Relay Validation**: Multiple validation layers ensure only legitimate transactions reach validators +- **Identity Verification**: Relay messages include cryptographic validation +- **Coherence Checks**: Transaction integrity verified at both relay and reception points + +### **3. Robust Fallback Mechanisms** +- **Network Partition Tolerance**: Graceful degradation when validators are unreachable +- **Byzantine Fault Tolerance**: System remains functional with malicious or offline validators +- **Conservative Safety**: Falls back to traditional behavior when DTR cannot operate safely + +## Technical Advantages + +### **1.

NodeCall Pattern + +**Structure** (from `manageNodeCall.ts`): + +```typescript +export async function manageNodeCall(content: NodeCall): Promise { + let response = _.cloneDeep(emptyResponse) + response.result = 200 + + switch (content.message) { + case "exampleCall": { + // Validate data + if (!data.requiredField) { + response.result = 400 + response.response = "Missing required field" +

NodeCalls**: + +```typescript +const result = await peer.call({ + method: "nodeCall", + params: [{ + message: "getL2PSParticipationById", + data: { l2psUid: "network_123" } + }] +}, true) // true = authenticated call + +if (result.result === 200) { + // Success + const data = result.response +} +``` + +**Parallel Peer Calls**: + +```typescript +const promises = new Map>() +for (const peer of
