oib 06e48ef34b chore: standardize configuration, logging, and error handling across blockchain node and coordinator API
- Add infrastructure.md and workflow files to .gitignore to prevent sensitive info leaks
- Change blockchain node mempool backend default from memory to database for persistence
- Refactor blockchain node logger with StructuredLogFormatter and AuditLogger (consistent with coordinator)
- Add structured logging fields: service, module, function, line number
- Unify coordinator config with Database

# Networking Configuration
Configure P2P networking for your blockchain node.
## Network Settings
### Firewall Configuration
```bash
# Allow P2P port
sudo ufw allow 7070/tcp
# Allow RPC port
sudo ufw allow 8080/tcp
# Allow from specific IPs
sudo ufw allow from 10.0.0.0/8 to any port 8080
```
### Port Forwarding
If behind a NAT, configure port forwarding:
- External port 7070 → Internal IP:7070
- External port 8080 → Internal IP:8080
## Bootstrap Nodes
### Default Bootstrap Nodes
```yaml
p2p:
bootstrap_nodes:
- /dns4/node-1.aitbc.com/tcp/7070/p2p/12D3KooW...
- /dns4/node-2.aitbc.com/tcp/7070/p2p/12D3KooW...
- /dns4/node-3.aitbc.com/tcp/7070/p2p/12D3KooW...
```
### Adding Custom Bootstrap Nodes
```bash
aitbc-chain p2p add-bootstrap /dns4/my-node.example.com/tcp/7070/p2p/...
```
## Peer Management
### Connection Limits
```yaml
p2p:
max_peers: 50
min_peers: 5
outbound_peers: 10
inbound_peers: 40
```
### Peer Scoring
Nodes are scored based on:
- Latency
- Availability
- Protocol compliance
- Block propagation speed
## NAT Traversal
### Supported Methods
| Method | Description |
|--------|-------------|
| AutoNAT | Automatic NAT detection |
| Hole Punching | UDP hole punching |
| Relay | TURN relay fallback |
### Configuration
```yaml
p2p:
nat:
enabled: true
method: auto # auto, hole_punching, relay
external_ip: 203.0.113.1
```
## Troubleshooting
### Check Connectivity
```bash
aitbc-chain p2p check-connectivity
```
### List Active Connections
```bash
aitbc-chain p2p connections
```
### Debug Mode
```bash
aitbc-chain start --log-level debug
```
