Abstract: In this paper, a blockchain smart contract-based smart contract is proposed to address the problems of data security threats, high management costs, and low scalability in centralized dynamic spectrum sharing. First, spectrum coupons are designed using the blockchain ERC4907 protocol to ensure the unique identification and leasing of spectrum resources. Second, the blockchain oracle machine was used to update the data of idle spectrum resources in real time to realize the upload of spectrum data. Finally, an auction algorithm based on smart contracts and Vue framework is used to auction the spectrum coupon lease term corresponding to the idle spectrum resources on the front-end page. Experimental results indicate that the proposed dynamic spectrum sharing scheme based on the blockchain smart contract ensures the users’ safe and effective dynamic spectrum sharing and is feasible.
