A Floating Calculation Revamp For the Ethereum Blockchain-Based IoT Systems

Abstract

It has become an industry consensus to integrate blockchain with other technologies to create a complete solution. Among the combinations, the Internet of Things can collect data on a large scale at a low cost, and the blockchain can trust data on a large scale at a low cost. With the development of Internet of Things(IoT) technology, the trend of networking of furniture is more apparent. The following security issues have also received more and more attention. Blockchain technology and smart contracts are widely regarded as a solution that can solve the networking of large scale terminals. But at the same time, due to the features of the blockchain, the floating calculation of smart contracts is unavoidable. This paper proposes a calculation revamp for the Ethereum-based smart contracts. Firstly, we verified the behaviour of our smart contract on Remix. Secondly, we implemented the smart contract on a blockchain-based IoT system. We confirmed the availability and reliability of our revamped smart contract.
