Problems solved by technology

[0005] In the non-mining consensus algorithm, if there is an error in the source data before it is added to the blockchain, the authenticity of the subsequent data will be doubted, and the storage space of the node will be wasted, a large number of meaningless blocks will be generated, and there will be May lead to "double spend" problem

Abstract

The embodiment of the invention discloses a block chain verification method, device and apparatus and a storage medium. The method comprises the following steps: a block verification node receives a block to be verified sent by a block generation node, and the block generation node is a node selected through a set consensus mechanism; the block verification node obtains financial transaction datain the block to be verified, wherein the financial transaction data includes at least one historical data identification information associated with the historical financial transaction data; the block verification node performs data verification on the financial transaction data in the block to be verified according to the historical data identification information of the financial transaction data. The technical scheme of the embodiment of the invention can effectively avoid the wrong data from being added into the block chain, thereby ensuring the validity of the data in a block chain network.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of blockchain, and in particular, to a blockchain verification method, device, equipment, and storage medium. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. In a distributed node system, nodes compete to obtain the right to process data as block generation nodes; the generated blocks are verified and confirmed by other nodes before being stored. The above operating mechanism makes it almost impossible for the data recorded in the block to be tampered with in the blockchain. [0003] In the existing technology, the blockchain mainly solves the trust and security issues of transactions, so one of the distinctive features is the distributed ledger. Specifically, the nodes in the blockchain system deliver transaction requests or a ...
