✅ Recommendations and Suggestions

Immediate Actions (Fix Network Operation)

1. 🔴 CRITICAL: Fix Besu Container Startup

   # Check logs on all nodes
   ssh besuadmin@<node-ip> 'cd /opt/docker-compose && docker compose logs besu --tail=50'
   
   # Verify genesis.json is accessible
   ssh besuadmin@<node-ip> 'ls -la /opt/besu/config/genesis.json'
   
   # Check config file paths are correct (container paths, not host paths)
   ssh besuadmin@<node-ip> 'grep -E "genesis-file|data-path" /opt/besu/config/*.toml'
   
   # Restart with clean state if needed
   ssh besuadmin@<node-ip> 'cd /opt/docker-compose && docker compose down && docker compose up -d'
   

2. 🔴 CRITICAL: Verify IBFT 2.0 Configuration

   # Check validator addresses in genesis.json
   python3 -c "import json; g=json.load(open('config/genesis.json')); print('Validators:', len(g.get('alloc', {})))"
   
   # Verify extraData is RLP-encoded (should be 420 chars)
   python3 -c "import json; g=json.load(open('config/genesis.json')); ed=g.get('extraData', '0x'); print(f'ExtraData length: {len(ed)}')"
   
   # Check validator key files exist
   ssh besuadmin@<node-ip> 'ls -la /opt/besu/keys/*.key'
