  - Remote node: http://aitbc.keisanki.net/rpc/
- ✅ **Current Status**: 
  - Transaction sync working
  - ✅ Block import endpoint fully functional with transaction support
  - ✅ Transaction data properly saved to database during block import
  - Endpoint validates blocks and handles imports correctly

  - Site C (remote): http://aitbc.keisanki.net/rpc/
  - All nodes maintain independent chains (PoA design)
  - Cross-site sync enabled with 10-second polling interval

## Recent Updates (2026-01-28)

### Transaction-Dependent Block Creation
