Hash-Based Synchronization Mechanism

To optimize the synchronization process and avoid transmitting unnecessary data, we propose using a unique hash for each node to identify changes. When a node reconnects after being offline, it verifies its local hash against the hashes stored by other connected nodes. Only the data corresponding to modified hashes is requested and transmitted, minimizing bandwidth usage and ensuring efficient synchronization.

This approach involves:

1. Generating a unique hash (e.g., SHA-256) for the graph state.
2. Storing and updating hashes for all subscribed nodes in the network.
3. When a node reconnects, it sends its local hash to compare with the hashes stored by other nodes.
4. If differences are detected, only the changes corresponding to the modified hashes are transmitted, avoiding redundant data transfer.

This mechanism ensures consistency across distributed nodes while improving efficiency and scalability.
