BLOCKCHAIN SMART CONTRACT-BASED DATA PROCESSING METHOD AND SYSTEM

摘要

A data processing method and system based on a blockchain smart contract are disclosed. In embodiments of the present specification, in one aspect, an XML processing instruction is defined and added to an instruction set of a blockchain virtual machine. In addition, XML processing logic corresponding to the XML processing instruction is deployed in the blockchain virtual machine. In another aspect, the defined XML processing instruction further needs to be added to an instruction set of a smart contract compiler, so a service smart contract compiled by using the smart contract compiler includes the XML processing instruction. As such, if the service smart contract is deployed in a blockchain network, when constructing a service initiation transaction, a user can specify to invoke the service smart contract to execute the service initiation transaction at the same time.
