Method and dual connection ledger structure blockchain to increase efficient transaction exploration and the security of the world state on the hyperledger fabric blockchain

摘要

The present invention prevents the risk of manipulation of the world state and guarantees the integrity of the world state by performing fast and efficient transaction discovery of the manipulated world state using a dual-connected ledger structure on the Hyperledger Fabric blockchain. It relates to a method for efficient transaction discovery and to increase the security of the world state on the Hyperledger Fabric blockchain, and to a blockchain with a dual-connected ledger structure. The block chain search method for efficient transaction search on the Hyperledger Fabric blockchain according to the present invention and for increasing the security of the world state includes the steps of searching for a transaction in a block in the ledger that matches each pointer of the world state (S100) and the The method may include comparing the state value of the transaction with the value of the world state based on the search result of the transaction to determine whether the state values match ( S200 ). In addition, if the state values match in the step of determining whether the state values match ( S200 ), a forward transaction pointer of a block matching the world state pointer in a forward transaction pointer list ( Forward transaction pointer list ) ) and determining whether the pointers match by comparing the world state pointer and the forward transaction pointer based on the search result of the forward transaction pointer (S300) and the forward transaction pointer (S400) may include
