Abstract

Advancements in cryptography and computer science have given birth to blockchain technology. One of the most exciting evolutions of blockchain is the advancements in smart contract technology. Smart contracts can be used for a broad range of use cases, not just financial transactions. Smart contract technology on the public blockchain, represented by Ethereum, due to its public and opaque nature, is not a good choice for many scenarios that do not require full disclosure, such as many IoT applications. On the other hand, the existing blockchain smart contract system still has a strong connection with virtual currency, which also limits its application in non-financial scenarios. In order to solve the above problems and explore more of the potential of smart contracts for the IoT application domain, this paper mainly explores the construction of a smart contract system based on consortium blockchains associated with no virtual currency. Based on the smart contract system designed in this project, blockchain can be more easily applied in payment, product traceability, authority authentication, and other fields. Through a certain centralized way, the system is easier to manage, can reduce the management expenditure, and the power and other resource consumption is less, which is conducive to environmental protection. Results show that our smart contract system has the potential for IoT usage in the future.
