Validator Cluster Change Proof for Trusted Blockchain State Sync

The patent applies preliminary action by having the target validator node pre-generate and provide proof of cluster change (including certificates and status information) before the newly added node performs verification. This allows the verification process to be more efficient as the proof materials are prepared in advance, reducing the time and computational resources needed during actual synchronization.

The patent extracts the verification burden from the newly added validator node by having the target validator node generate and provide the proof of cluster change. Instead of requiring the new node to independently verify each status change, the target node extracts and provides the necessary proof materials (certificates, status information), significantly reducing the computational load on new nodes.

The patent introduces an intermediary mechanism where the target validator node acts as a mediator that generates and provides proof of cluster change. This intermediary approach maintains verification accuracy by providing cryptographic proof while simplifying the overall system complexity by centralizing the proof generation responsibility rather than requiring each new node to independently verify all historical changes.

The patent uses copying by having the target validator node create and provide copies of the proof of cluster change (including certificates and status information) to newly added nodes. This allows new nodes to verify status accuracy without independently reconstructing the entire verification chain, reducing computational complexity while maintaining verification integrity.
