摘要
为解决数字孪生城市各类数据目录确权和分权管控问题,基于区块链的公开、分权、不可篡改、合约机制等理念,阐述了数字孪生城市目录区块链平台的总体架构,以及共识机制、多子链机制和智能合约等关键技术,实现数据与职责的强关联、数据变化的实时探知及数据访问的全程留痕,有效解决了城市各类数据可用、可见、目录变更和数据共享授权随意、数据更新不及时等问题。
In order to solve the problem of power determination and decentralized control of various data directories in the digital twin city,based on the concepts of blockchain openness,decentralization,tamper proof,and contract mechanism,this paper expounds the overall architecture and consensus mechanism,multi-subchain mechanism,smart contract and other key technologies of the blockchain platform of the data twin city directory,so as to realize the strong correlation between data and responsibilities,real-time detection of data changes,and the full trace of data access,it has effectively solved the problems such as the availability and visibility of various urban data,random directory changes and data sharing authorization,and untimely data updates.
