# Direct TCP P2P Mesh Network Update
|
|
|
|
The AITBC blockchain network has been upgraded from a Redis-backed PubSub gossip model to a **Direct TCP P2P Mesh Network** running on port `7070`.
|
|
|
|
## Architecture Changes
|
|
- The `P2PNetworkService` (`p2p_network.py`) now directly binds to port `7070` via `asyncio.start_server`.
|
|
- The `gossip_backend` variable is now strictly set to `memory` since external block/transaction propagation is handled via P2P TCP streams rather than a centralized Redis bus.
|
|
- Nodes identify themselves securely via a JSON handshake (`{'type': 'handshake', 'node_id': '...'}`).
|
|
|
|
## Configuration Flags
|
|
The `/etc/aitbc/blockchain.env` configuration now requires explicit peer targeting instead of Redis connection strings:
|
|
|
|
```bash
|
|
# Removed:
|
|
# gossip_backend=broadcast
|
|
# gossip_broadcast_url=redis://localhost:6379
|
|
|
|
# Updated/Added:
|
|
gossip_backend=memory
|
|
p2p_bind_host=0.0.0.0
|
|
p2p_bind_port=7070
|
|
p2p_peers=aitbc1:7070,aitbc2:7070 # Comma-separated list of known nodes
|
|
```
|
|
|
|
## Systemd Service
|
|
The systemd service (`/etc/systemd/system/aitbc-blockchain-p2p.service`) has been updated to reflect the new CLI arguments:
|
|
```ini
|
|
ExecStart=/opt/aitbc/venv/bin/python -m aitbc_chain.p2p_network \
|
|
--host ${p2p_bind_host} \
|
|
--port ${p2p_bind_port} \
|
|
--peers ${p2p_peers} \
|
|
--node-id ${proposer_id}
|
|
```
|
|
|
|
## Troubleshooting
|
|
If a node is failing to sync, verify that TCP port `7070` is open between the nodes (`ufw allow 7070/tcp`), and check the mesh connectivity status using the journal logs:
|
|
```bash
|
|
journalctl -u aitbc-blockchain-p2p -n 50 --no-pager
|
|
```
|
|
You should see output similar to `Successfully dialed outbound peer at aitbc1:7070` or `Handshake accepted from node...`
