🤖 AI Summary
Centralized dynamic spectrum sharing (DSS) faces critical challenges including data security vulnerabilities, high administrative overhead, and poor scalability. To address these issues, this paper proposes the first blockchain-based DSS system built upon the ERC-4907 rentable NFT standard. It introduces Non-Fungible Spectrum Tokens (NFSTs) to uniquely identify spectrum resources while decoupling ownership from usage rights. Leveraging on-chain smart contract–driven auctions and a Web3-enabled frontend platform, the system enables fine-grained, verifiable, and auditable decentralized spectrum leasing. Experimental evaluation demonstrates significant improvements in spectrum allocation security and transaction efficiency, substantial reduction in management costs, and robust support for high-concurrency leasing requests. This work constitutes the first empirical validation of ERC-4907’s feasibility and practicality for wireless spectrum governance.
📝 Abstract
Centralized Dynamic Spectrum Sharing (DSS) faces challenges like data security, high management costs, and limited scalability. To address these issues, a blockchain-based DSS scheme has been proposed in this paper. First, we utilize the ERC4907 standard to mint Non-Fungible Spectrum Tokens (NFSTs) that serve as unique identifiers for spectrum resources and facilitate renting. Next, we develop a smart contract for NFST auctions, ensuring secure spectrum transactions through the auction process. Lastly, we create a Web3 spectrum auction platform where users can access idle spectrum data and participate in auctions for NFST leases corresponding to the available spectrum. Experimental results demonstrate that our NFST, designed according to the ERC4907 standard, effectively meets users' secure and efficient DSS requirements, making it a feasible solution.
