METHOD AND DEVICE FOR RESTORING BLOCKCHAIN NETWORK WITH ITS CREDIBILITY ON BACKUP DATA MAINTAINED AND MINIMIZING RESOURCE USAGE BY USING DELAYED SYNCHRONIZATION RECYCLING NODES

摘要

A delayed synchronization method is disclosed that restores the blockchain network while securing the reliability of backup data and minimizes resource consumption by recycling nodes. That is, (a) a state in which a specific delay node, which is set to perform a certain function by acquiring command triggering information from a certain manager terminal included in the blockchain network, maintains a certain delay according to its own initial setting. Synchronizing with existing service nodes included in the blockchain network; And (b) when the specific delay node obtains conversion triggering information from the manager terminal, support to synchronize at least some of the existing service nodes without the predetermined delay based on the delay blocks included therein. And performing at least one process in which it is configured to function as the new service node while supporting to function as a new service node.
