Abstract

The invention discloses a transaction information verification method and a related device. The method is applied to the lightweight node, the light node stores a root node of the state tree, whereinthe state tree is used for storing state data of each user account in the block chain network; after receiving a to-be-processed transaction, a transfer-out party account and to-be-verified information corresponding to the transaction are determined, a target state data acquisition request related to the to-be-verified information is initiated to the total node,target state data and Merkle proof for verifying whether the target state data is true or not are obtained; according to the Merkle tree principle, only the root node of the state tree needs to be stored in the light-weight nodes, and when the target state data is verified, whether the target state data is real or not can be verified through the Merkle proof and the stored real root node. Therefore, for a lightweight node serving asan accounting node, the verification of the to-be-verified information can be completed only by storing the root node of the state tree without storing the state data of all the user accounts, and the real reliability of a verification result is ensured.

Description

technical field [0001] The present invention relates to blockchain technology, in particular to a transaction information verification method, device, system and computer-readable storage medium. Background technique [0002] Blockchain is a continuously growing list of records, which are connected back and forth through cryptographic methods, and have the characteristics of non-tampering, openness, and transparency. [0003] In the blockchain, bookkeeping nodes package transactions to obtain blocks, and then add blocks to the blockchain. Bookkeeping nodes, also known as mining nodes, refer to nodes that participate in consensus in the blockchain system. Before the bookkeeping node packs the transaction into a block, it needs to verify whether the current transaction is correct, that is, it needs to verify whether the corresponding state data of both parties to the transaction can satisfy the transaction. Therefore, in order to be able to verify the state data of both partie...
