Unmanned aerial vehicle relay system spectrum block chain sharing method based on smart contract

The invention discloses an unmanned aerial vehicle relay system spectrum block chain sharing method based on a smart contract. The method comprises the steps that an unmanned aerial vehicle creates and deploys the smart contract in a block chain network; the unmanned aerial vehicle and the ground user register registration information through a smart contract; and the block chain network performs information storage and state information updating by using the smart contract. A reputation mechanism is introduced to effectively identify and punish malicious nodes, a lightweight consensus algorithm is adopted to reduce consumption of calculation and storage resources of the nodes, the consensus algorithm and the reputation mechanism are associated to establish a reward and punishment mechanism, and an intelligent contract is introduced to enable various transactions and business logics in the network to be automatically executed. 本发明公开一种基于智能合约的无人机中继系统频谱区块链共享方法，包括：无人机在区块链网络中创建并部署智能合约；无人机和地面用户通过智能合约注册登记信息；区块链网络利用智
