【摘要】 为了解决目前城市车位信息不流通、停车系统交易凭证不可靠、停车支付不高效以及数据存储不安全等弊端，提出了基于Fabric区块链的城市智慧停车方案。利用区块链数据共享的特性，允许车位拥有者将空闲车位上传至区块链，实现车位实时共享并保证数据真实；利用预制在区块链上的智能合约，实现停车后自动缴费；利用区块链数据不可篡改且可追溯的特性，保证交易数据的真实性。最后通过搭建分布式区块链系统，并对系统进行测试，验证了该方案的可行性。更多还原

【Abstract】 To solve the disadvantages of non circulation of urban parking space information,unreliable transaction voucher of parking system,inefficient parking payment and unsafe data storage,an urban intelligent parking scheme based on Fabric is proposed. Using the characteristics of data sharing in blockchain,parking space owners are allowed to upload free parking spaces to blockchain,so as to realize real-time sharing of parking spaces and ensure the authenticity of data. Automatic payment after parking is realized by using the smart contract technology prefabricated on the blockchain. The authenticity of transaction data is guaranteed by taking advantage of the non tamperability and traceability of blockchain data. Finally,the feasibility of the scheme is verified by building a distributed blockchain system and testing the system.更多还原
