This architecture enables: +- **Horizontal scaling**: Each chain has its own hub node for block production +- **Redundancy**: Member nodes receive blocks from multiple chains via gossip +- **Isolation**: Chain-specific databases prevent cross-chain contamination +- **Efficiency**: Gossip-based sync eliminates need for periodic RPC polling + +### **Use Case** +Organizations running multiple blockchain networks (e.g., mainnet and testnet) can deploy this architecture to: +- Distribute block production load across multiple nodes +- Ensure all nodes stay synchronized across chains +- Provide redundancy and fault tolerance +- Enable cross-chain operations without direct RPC dependencies + +### **What You'll Learn** +- How to configure multi-chain island architecture with hub and member nodes +- Redis gossip-based block synchronization +- Chain-specific database management +- Cross-chain broadcasting and subscription +- Troubleshooting gossip sync issues + +--- + +## πŸ“‹ **Prerequisites + +### **Knowledge Required** +- Understanding of blockchain consensus and block production +- Redis Pub/Sub basics +- Systemd service management +- SQLite database operations + +### **Tools Required** +- Redis server (redis://10.1.223.93:6379) +- SSH access to aitbc, aitbc1, and gitea-runner +- Python 3.13+ with broadcaster module installed + +### **Setup Required** +- AITBC blockchain node installed on all three machines +- Redis server configured and accessible from all nodes +- Systemd service files for aitbc-blockchain-node + +--- + +## πŸ”§ **Step-by-Step Workflow + +### **Architecture Overview + +The multi-chain island architecture consists of three nodes with specific roles: + +| Node | Role | Block Production Chains | Supported Chains | Purpose | +|------|------|------------------------|------------------|---------| +| aitbc | Hub of ait-mainnet, Member of ait-testnet | ait-mainnet | ait-mainnet, ait-testnet | Produces mainnet blocks, receives testnet blocks via gossip | +| aitbc1 | Hub of ait-testnet, Member of ait-mainnet | ait-testnet | ait-mainnet, ait-testnet | Produces testnet blocks, receives mainnet blocks via gossip | +| gitea-runner | Member of both chains | (none) | ait-mainnet, ait-testnet | Receives both chains via gossip, no block production | + +### **Step 1: Install Required Dependencies + +Ensure the `broadcaster` module is installed on all nodes for Redis gossip backend: + +```bash +# On aitbc +cd /opt/aitbc +source venv/bin/activate +pip install broadcaster>=0.3.1 + +# On aitbc1 +ssh aitbc1 'cd /opt/aitbc && source venv/bin/activate && pip install broadcaster>=0.3.1' + +# On gitea-runner +ssh gitea-runner 'cd /opt/aitbc && source venv/bin/activate && pip install broadcaster>=0.3.1' +``` + +### **Step 2: Configure aitbc (Hub of ait-mainnet) + +Edit `/etc/aitbc/.env` on aitbc: + +```bash +# Configure aitbc as hub of ait-mainnet, member of ait-testnet +block_production_chains=ait-mainnet +supported_chains=ait-mainnet,ait-testnet +gossip_backend=broadcast +gossip_broadcast_url=redis://10.1.223.93:6379 +``` + +### **Step 3: Configure aitbc1 (Hub of ait-testnet) + +Edit `/etc/aitbc/.env` on aitbc1: + +```bash +ssh aitbc1 'cat > /etc/aitbc/.env << EOF +block_production_chains=ait-testnet +supported_chains=ait-mainnet,ait-testnet +gossip_backend=broadcast +gossip_broadcast_url=redis://10.1.223.93:6379 +default_peer_rpc_url=http://10.1.223.93:8006 +EOF' +``` + +### **Step 4: Configure gitea-runner (Member of both chains) + +Edit `/etc/aitbc/.env` on gitea-runner: + +```bash +ssh gitea-runner 'cat > /etc/aitbc/.env << EOF +block_production_chains= +supported_chains=ait-mainnet,ait-testnet +gossip_backend=broadcast +gossip_broadcast_url=redis://10.1.223.93:6379 +default_peer_rpc_url=http://10.1.223.93:8006 +EOF' +``` + +### **Step 5: Clear Stale Databases (if needed) + +If nodes have corrupted or stale chain data, clear the databases: + +```bash +# Clear aitbc1's ait-mainnet database (member role, not hub) +ssh aitbc1 'systemctl stop aitbc-blockchain-node && rm -rf /var/lib/aitbc/data/ait-mainnet && systemctl start aitbc-blockchain-node' + +# Clear gitea-runner's ait-testnet database (member role, not hub) +ssh gitea-runner 'systemctl stop aitbc-blockchain-node && rm -rf /var/lib/aitbc/data/ait-testnet && systemctl start aitbc-blockchain-node' +``` + +### **Step 6: Restart All Blockchain Services + +```bash +systemctl restart aitbc-blockchain-node +ssh aitbc1 'systemctl restart aitbc-blockchain-node' +ssh gitea-runner 'systemctl restart aitbc-blockchain-node' +``` + +### **Step 7: Verify Gossip Subscriptions + +Check that each node is subscribed to the correct Redis topics: + +```bash +# Check Redis subscriber count +redis-cli -h 10.1.223.93 -p 6379 PUBSUB NUMSUB blocks.ait-mainnet +redis-cli -h 10.1.223.93 -p 6379 PUBSUB NUMSUB blocks.ait-testnet +``` + +Expected output: 3 subscribers for each topic (aitbc, aitbc1, gitea-runner) + +### **Step 8: Verify Block Production + +Check that each hub is producing blocks for its designated chain: + +```bash +# Check aitbc producing ait-mainnet blocks +journalctl -u aitbc-blockchain-node --no-pager | grep "\[BROADCAST\].*ait-mainnet" + +# Check aitbc1 producing ait-testnet blocks +ssh aitbc1 'journalctl -u aitbc-blockchain-node --no-pager | grep "\[BROADCAST\].*ait-testnet"' +``` + +### **Step 9: Verify Cross-Chain Sync + +Check that nodes are receiving blocks from other chains via gossip: + +```bash +# Check aitbc receiving ait-testnet blocks +journalctl -u aitbc-blockchain-node --no-pager | grep "Received block.*ait-testnet" + +# Check aitbc1 receiving ait-mainnet blocks +ssh aitbc1 'journalctl -u aitbc-blockchain-node --no-pager | grep "Received block.*ait-mainnet"' + +# Check gitea-runner receiving both chains +ssh gitea-runner 'journalctl -u aitbc-blockchain-node --no-pager | grep "Received block"' +``` + +--- + +## πŸ§ͺ **Validation + +Validate this scenario with the shared 3-node harness: + +```bash +bash scripts/workflow/44_comprehensive_multi_node_scenario.sh +``` + +**Node coverage**: +- `aitbc1`: hub of ait-testnet, member of ait-mainnet +- `aitbc`: hub of ait-mainnet, member of ait-testnet +- `gitea-runner`: member of both chains + +**Validation guide**: +- [Scenario Validation Guide](./VALIDATION.md) + +**Expected result**: +- aitbc produces ait-mainnet blocks only +- aitbc1 produces ait-testnet blocks only +- gitea-runner produces no blocks +- All nodes receive blocks from both chains via gossip +- Redis subscriber count is 3 for each topic +- No "Gap detected" or "Fork detected" errors +- Chain-specific databases remain isolated + +**Manual validation commands**: + +```bash +# Verify block production roles +journalctl -u aitbc-blockchain-node --no-pager | grep "Skipping block

+``` + +--- + +## πŸ’» **Code Examples Using Agent SDK + +### **Example 1: Query Multi-Chain Node Status** + +```python +from aitbc_agent_sdk import Agent, AgentConfig + +config = AgentConfig( +

+testnet_status = agent.get_chain_status("ait-testnet") + +print(f"Mainnet height: {mainnet_status['height']}") +print(f"Testnet height: {testnet_status['height']}") +``` + +### **Example 2: Cross-Chain Transaction Monitoring** + +```python +# Monitor transactions across both chains +async def monitor_multi_chain(): + while True: + # Check mainnet + mainnet_txs = await agent.get_pending_transactions("ait-mainnet") + # Check testnet + testnet_txs = await agent.get_pending_transactions("ait-testnet") + + print(f"Mainnet pending: {len(mainnet_txs)}") + print(f"Testnet
