# AITBC Blockchain Node Deployment Summary
|
|
|
|
## Overview
|
|
Successfully deployed two independent AITBC blockchain nodes on the same server for testing and development.
|
|
|
|
## Node Configuration
|
|
|
|
### Node 1
|
|
- **Location**: `/opt/blockchain-node`
|
|
- **P2P Port**: 7070
|
|
- **RPC Port**: 8082
|
|
- **Database**: `/opt/blockchain-node/data/chain.db`
|
|
- **Status**: ✅ Operational
|
|
- **Chain Height**: 717,593+ (actively producing blocks)
|
|
|
|
### Node 2
|
|
- **Location**: `/opt/blockchain-node-2`
|
|
- **P2P Port**: 7071
|
|
- **RPC Port**: 8081
|
|
- **Database**: `/opt/blockchain-node-2/data/chain2.db`
|
|
- **Status**: ✅ Operational
|
|
- **Chain Height**: 174+ (actively producing blocks)
|
|
|
|
## Services
|
|
|
|
### Systemd Services
|
|
```bash
|
|
# Node 1
|
|
systemctl status blockchain-node # Consensus node
|
|
systemctl status blockchain-rpc # RPC API
|
|
|
|
# Node 2
|
|
systemctl status blockchain-node-2 # Consensus node
|
|
systemctl status blockchain-rpc-2 # RPC API
|
|
```
|
|
|
|
### API Endpoints
|
|
- Node 1 RPC: `http://127.0.0.1:8082/docs`
|
|
- Node 2 RPC: `http://127.0.0.1:8081/docs`
|
|
|
|
## Testing
|
|
|
|
### Test Scripts
|
|
1. **Basic Test**: `/opt/test_blockchain_simple.py`
|
|
- Verifies node responsiveness
|
|
- Tests faucet functionality
|
|
- Checks chain head
|
|
|
|
2. **Comprehensive Test**: `/opt/test_blockchain_nodes.py`
|
|
- Full test suite with multiple scenarios
|
|
- Currently shows nodes operating independently
|
|
|
|
### Running Tests
|
|
```bash
|
|
cd /opt/blockchain-node
|
|
source .venv/bin/activate
|
|
cd ..
|
|
python test_blockchain_final.py
|
|
```
|
|
|
|
## Current Status
|
|
|
|
### ✅ Working
|
|
- Both nodes are running and producing blocks
|
|
- RPC APIs are responsive
|
|
- Faucet (minting) is functional
|
|
- Transaction submission works
|
|
- Block production active (2s block time)
|
|
|
|
### ⚠️ Limitations
|
|
- Nodes are running independently (not connected)
|
|
- Using memory gossip backend (no cross-node communication)
|
|
- Different chain heights (expected for independent nodes)
|
|
|
|
## Production Deployment Guidelines
|
|
|
|
To connect nodes in a production network:
|
|
|
|
### 1. Network Configuration
|
|
- Deploy nodes on separate servers
|
|
- Configure proper firewall rules
|
|
- Ensure P2P ports are accessible
|
|
|
|
### 2. Gossip Backend
|
|
- Use Redis for distributed gossip:
|
|
```env
|
|
GOSSIP_BACKEND=redis
|
|
GOSSIP_BROADCAST_URL=redis://redis-server:6379/0
|
|
```
|
|
|
|
### 3. Peer Discovery
|
|
- Configure peer list in each node
|
|
- Use DNS seeds or static peer configuration
|
|
- Implement proper peer authentication
|
|
|
|
### 4. Security
|
|
- Use TLS for P2P communication
|
|
- Implement node authentication
|
|
- Configure proper access controls
|
|
|
|
## Troubleshooting
|
|
|
|
### Common Issues
|
|
1. **Port Conflicts**: Ensure ports 7070/7071 and 8081/8082 are available
|
|
2. **Permission Issues**: Check file permissions in `/opt/blockchain-node*`
|
|
3. **Database Issues**: Remove/rename database to reset chain
|
|
|
|
### Logs
|
|
```bash
|
|
# Node logs
|
|
sudo journalctl -u blockchain-node -f
|
|
sudo journalctl -u blockchain-node-2 -f
|
|
|
|
# RPC logs
|
|
sudo journalctl -u blockchain-rpc -f
|
|
sudo journalctl -u blockchain-rpc-2 -f
|
|
```
|
|
|
|
## Next Steps
|
|
|
|
1. **Multi-Server Deployment**: Deploy nodes on different servers
|
|
2. **Redis Setup**: Configure Redis for shared gossip
|
|
3. **Network Testing**: Test cross-node communication
|
|
4. **Load Testing**: Test network under load
|
|
5. **Monitoring**: Set up proper monitoring and alerting
