# 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
|
|
```
