- Add default_peer_rpc_url configuration parameter
- Update bulk sync fallback to use default_peer_rpc_url instead of gossip_broadcast_url
- Fixes 'unsupported protocol redis://' error in bulk sync
- gossip_broadcast_url is for Redis backend, not HTTP RPC calls
- Add _calculate_dynamic_batch_size method to sync.py
- Scale batch size based on gap size:
- Small gaps (< 100): 20-50 blocks for precision
- Medium gaps (100-500): 50-100 blocks
- Large gaps (> 500): 100-200 blocks for speed

- Suppresses Bandit security scan warnings
- Add p2p_node_id field to ChainSettings with empty string default
- Add p2p_node_id to .env.example configuration file
- Change --node-id argument from required to optional with default empty string

- Add NAT traversal configuration (STUN/TURN servers and credentials)
- Add DEFAULT_ISLAND_ID using UUID for new installations
- Extend PeerNode with public_address, public_port, island_id, island_chain_id, and is_hub fields

- Add propose_only_if_mempool_not_empty config option (default: True) to skip block proposals when mempool is empty
- Add detailed logging for transaction processing in block proposals (sender/recipient validation, balance checks, duplicate detection)
- Check for existing transactions in database before adding to prevent duplicates
- Improve genesis block creation: check by height and hash, use "genesis" as proposer to avoid hash conflicts
- Add proper error handling and rollback for
- Remove duplicate /opt/aitbc/cli/requirements.txt file
- All CLI dependencies already covered in central requirements.txt
- Central requirements has newer versions of all CLI dependencies
- Update workflow documentation to reflect central venv usage
