Abstract

The invention provides a transaction verification method and device based on a directed acyclic graph. The method comprises the steps that a first node verifies first transaction information, and thefirst transaction information is sent out by a second node; whether the transaction reaches a preliminary consensus or not is judged according to a verification result of the first node; and if the transaction reaches the preliminary consensus, the third node judges whether the transaction reaches the final consensus according to the collected transaction information of the whole network, and thethird node is a node generated according to election. Through the technical scheme of the invention, the effect of improving the transaction verification efficiency on the premise of ensuring the security of the transaction data is achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of block chains, in particular to a transaction verification method and device based on a directed acyclic graph. 【Background technique】 [0002] Since the blockchain uses distributed accounting and storage, there is no centralized hardware or management organization, and the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by nodes with maintenance functions in the entire system. [0003] The transaction process of the blockchain completely follows the concept of "decentralization", and any operation must be approved and audited by the entire network, which can effectively prevent fraud and tampering. [0004] From another point of view, it is precisely because of such a strict audit mechanism of the blockchain that while improving security, it also leads to the problem of low transaction verification efficiency. 【Content of invention】 [0005] The ...
