METHOD FOR MAINTAINING INDEXES AND CHAIN TOPOLOGY BETWEEN MULTI-LEVEL BLOCKCHAIN SYSTEMS

摘要

The present invention relates to a method for maintaining indexes and chain topology between multi-level blockchain systems, comprising: A. a top-level blockchain indexing a lower-level blockchain by recoding a next seed node in the transaction record of a block; B. maintaining a distributed monitoring cluster, periodically detecting the availability of corresponding IP addresses and ports of a seed node list recorded in the top-level blockchain; C. each node of the lower-level blockchain needing to maintain a common global routing table structure to store the topology of the entire blockchain cluster, and maintain the final consistency of the global routing table by means of a Gossip-based protocol propagation method. A multi-level blockchain can quickly index, by means of the records in the blockchain, a lower-level blockchain; and as the topology of a complete blockchain is maintained on the seed node, any client can obtain responsive nodes of the complete blockchain by means of the seed node.
