BLOCKCHAIN-BASED TRANSACTION METHOD AND APPARATUS, ELECTRONIC DEVICE, AND READABLE STORAGE MEDIUM

摘要

A blockchain-based transaction method and apparatus, an electronic device, and a readable storage medium. The method comprises: after receiving a local area network networking request sent by a first node in a wide area network, creating, according to a preset networking rule, a local area network consisting of the first node, a second node, and a third node (S10); obtaining a network segment code of the created local area network, and according to a preset mapping relationship between the network segment code and a smart contract, determining the smart contract corresponding to the network segment code of the created local area network (S20); and after receiving a transaction request with the second node and the third node initiated by the first node, running the determined smart contract in the created local area network to perform reading and writing on an account book, so as to complete the transaction between the first node and the second node, and between the first node and the third node (S30). The security of some of the node transactions in a blockchain network is improved.
