基于可扩展区块链的智慧城市框架

Smart City Framework Based on Scalable Blockchain

为解决智慧城市中的大数据相关隐私和安全问题,提出一种基于多链和分片技术的异构多链可扩展区块链结构,使高效的跨链事务具有高可伸缩性和可扩展性.并设计了基于可扩展区块链的智慧城市框架,该框架由物理层、通信层、平台层和应用层组成,其中通信层与可扩展区块链集成,通过内容分发协议和智能合约等区块链技术保证传输数据的安全性和隐私性.平台层中区块链分布式分类帐本数据库,安全存储交易记录.通过可扩展区块链智慧城市框架,更好地支持大规模业务应用,实现智慧城市的建设和发展.

In order to solve the privacy and security problems related to big data in smart cities,an extensible blockchain intelligent city structure has been proposed.Firstly,a heterogeneous multi-chain extensible block chain structure based on multi-chain and fragmentation technology has been proposed,which makes efficient cross-chain transactions highly scalable and scalable.Secondly,the communication layer has been integrated with the scalable blockchain to ensure the security and privacy of the transmitted data through blockchain technologies such as content distribution protocols and smart contracts.And lastly,the blockchain distributed ledger database in the platform layer securely stores transaction records.Through the extensible blockchain smart city framework,better support large-scale business applications,to achieve the construction and development of smart cities.
