Research On Industrial Blockchain Smart Contract Virtual Machine

Industrial Internet of Things(IIo T)is an important direction and trend of the current socio-economic development,with broad application prospects and enormous development potential.However,there are many problems in the current IIo T,including poor data security,difficulties in data sharing,low data credibility,and poor data timeliness,which seriously restrict the application and development of IIo T.Blockchain technology,as a decentralized technology,can bring many benefits to IIo T applications,providing more reliable,secure,efficient,and transparent solutions for IIo T applications.Blockchain technology is a decentralized technology that integrates cryptography,consensus mechanisms,and smart contracts to solve many challenges faced by the IIo T,including data security,data sharing,data validity,and data timeliness,and provides a more reliable,secure,efficient,and transparent solution for IIo T applications.In blockchain,the virtual machine plays a critical role as it is the execution engine responsible for processing transactions and executing smart contracts on the blockchain.The optimization and adaptation of the virtual machine are crucial for the reliability,efficiency,and security of the entire industrial blockchain system,and therefore research on the virtual machine is essential for the development of industrial blockchain.Thesis focuses on the virtual machine of industrial blockchain and proposes an architecture for an industrial blockchain smart contract virtual machine.This architecture consists of four modules: transaction pre-processing module,account state management module,operation instruction set,and virtual machine kernel.Thesis provides a detailed design and implementation of these four modules.In addition,this article designs operation instructions related to the Internet of Things(Io T),and the virtual machine can directly control Io T devices through these operation instructions.The correctness of all operation functions in the virtual machine operation instruction set was verified through experimental testing.Finally,the feasibility of this virtual machine in industrial Io T applications was verified.
