# Blockchain Node Deployment Guide
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Python 3.13.5+
|
||||
- SQLite 3.35+
|
||||
- 512 MB RAM minimum (1 GB recommended)
|
||||
- 10 GB disk space
|
||||
|
||||
## Configuration
|
||||
|
||||
All settings via environment variables or `.env` file:
|
||||
|
||||
```bash
|
||||
# Core
|
||||
CHAIN_ID=ait-devnet
|
||||
DB_PATH=./data/chain.db
|
||||
PROPOSER_ID=ait-devnet-proposer
|
||||
BLOCK_TIME_SECONDS=2
|
||||
|
||||
# RPC
|
||||
RPC_BIND_HOST=0.0.0.0
|
||||
RPC_BIND_PORT=8080
|
||||
|
||||
# Block Production
|
||||
MAX_BLOCK_SIZE_BYTES=1000000
|
||||
MAX_TXS_PER_BLOCK=500
|
||||
MIN_FEE=0
|
||||
|
||||
# Mempool
|
||||
MEMPOOL_BACKEND=database # "memory" or "database"
|
||||
MEMPOOL_MAX_SIZE=10000
|
||||
|
||||
# Circuit Breaker
|
||||
CIRCUIT_BREAKER_THRESHOLD=5
|
||||
CIRCUIT_BREAKER_TIMEOUT=30
|
||||
|
||||
# Sync
|
||||
TRUSTED_PROPOSERS=proposer-a,proposer-b
|
||||
MAX_REORG_DEPTH=10
|
||||
SYNC_VALIDATE_SIGNATURES=true
|
||||
|
||||
# Gossip
|
||||
GOSSIP_BACKEND=memory # "memory" or "broadcast"
|
||||
GOSSIP_BROADCAST_URL= # Required for broadcast backend
|
||||
```
|
||||
|
||||
## Installation
|
||||
|
||||
```bash
|
||||
cd apps/blockchain-node
|
||||
pip install -e .
|
||||
```
|
||||
|
||||
## Running
|
||||
|
||||
### Development
|
||||
```bash
|
||||
uvicorn aitbc_chain.app:app --host 127.0.0.1 --port 8080 --reload
|
||||
```
|
||||
|
||||
### Production
|
||||
```bash
|
||||
uvicorn aitbc_chain.app:app \
|
||||
--host 0.0.0.0 \
|
||||
--port 8080 \
|
||||
--workers 1 \
|
||||
--timeout-keep-alive 30 \
|
||||
--access-log \
|
||||
--log-level info
|
||||
```
|
||||
|
||||
**Note:** Use `--workers 1` because the PoA proposer must run as a single instance.
|
||||
|
||||
### Systemd Service
|
||||
```ini

||||
## Endpoints
|
||||
|
||||
| Method | Path | Description |
|
||||
|--------|------|-------------|
|
||||
| GET | `/health` | Health check |
|
||||
| GET | `/metrics` | Prometheus metrics |
|
||||
| GET | `/rpc/head` | Chain head |
|
||||
| GET | `/rpc/blocks/{height}` | Block by height |
|
||||
| GET | `/rpc/blocks` | Latest blocks |
|
||||
| GET | `/rpc/tx/{hash}` | Transaction by hash |
|
||||
| POST | `/rpc/sendTx` | Submit transaction |
|
||||
| POST | `/rpc/importBlock` | Import block from peer |
|
||||
| GET | `/rpc/syncStatus` | Sync status |
|
||||
| POST | `/rpc/admin/mintFaucet` | Mint devnet funds |
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Health Check
|
||||
```bash
|
||||
curl http://localhost:8080/health
|
||||
```
|
||||
|
||||
### Key Metrics
|
||||
- `poa_proposer_running` — 1 if proposer is active
|
||||
- `chain_head_height` — Current block height
|
||||
- `mempool_size` — Pending transactions
|
||||
- `circuit_breaker_state` — 0=closed, 1=open
|
||||
- `rpc_requests_total` — Total RPC requests
|
||||
- `rpc_rate_limited_total` — Rate-limited requests
|
||||
|
||||
### Alerting Rules (Prometheus)
|
||||
```yaml
|
||||
- alert: ProposerDown
|
||||
expr: poa_proposer_running == 0
|
||||
for: 1m
|
||||
|
||||
- alert: CircuitBreakerOpen
|
||||
expr: circuit_breaker_state == 1
|
||||
for: 30s
|
||||
|
||||
- alert: HighErrorRate
|
||||
expr: rate(rpc_server_errors_total[5m]) > 0.1
|
||||
for: 2m
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
- **Proposer not producing blocks**: Check `poa_proposer_running` metric, review logs for DB errors
|
||||
- **Rate limiting**: Increase `max_requests` in middleware or add IP allowlist
|
||||
- **DB locked**: Switch to `MEMPOOL_BACKEND=database` for separate mempool DB
|
||||
- **Sync failures**: Check `TRUSTED_PROPOSERS` config, verify peer connectivity
