Description
Technical Field
The invention relates to a city service data management system, in particular to a city service data cooperation method based on a block chain.
Background
At present, with the development of block chain technology in recent years, the technical characteristics of decentralization, difficult tampering, open trust and traceability make the block chain technology suitable for being applied to different fields. Correspondingly, the method has been expanded from the financial field to various social industries, has rich application scenes in the aspects of government affair management and public service, and has wide prospects.
In recent years, with the development and popularization of the block chain technology, the technology is more mature and applied to related fields. The blockchain is mostly realized by adopting a decentralized distributed architecture, each operation can be effective only through the consensus operation of all blockchain nodes in the system, meanwhile, the blockchain can timely carry out the whole network synchronization on the data through a preset data synchronization rule, and the consensus algorithm has very strong tolerance on node delay, packet loss, downtime and even malicious operation, so that the consistency of the data among the nodes can be realized under the unreliable network environment. Each relative node keeps all data in a local consistency mode according to the synchronization rule, and any node cannot tamper or delete the data.
The specific application of blockchain + urban service can be roughly divided into three aspects: and the urban service flow is optimized, and urban service disclosure, fairness and authentication are promoted. The block chain is a trusted network established on the basis of the Internet, so that the traditional government affair service can be broken through by a government through the block chain network in the urban service and management process, the difficult problems of 'administration of each person' and 'information island' are solved, the operation cost is reduced through a distributed structure, the data information is prevented from being stolen and copied in the block chain information interaction process, the safety and the authenticity of data are guaranteed, the urban service flow can be cooperated with departments to work, the urban service communication cost and the information cost are reduced, and the government management efficiency is improved.
The application of the block chain technology can help government data to obtain a new promotion mode, the combination of the original government data set and the block chain technology makes full use of the characteristics of the block chain technology, the problems of data safety and data right are solved, and open multi-component co-treatment of data is realized. The decentralized characteristic of the block chain technology abandons the top-down running state in the traditional data management mode, and instead, the common participation of a plurality of main bodies is sought, so that the multivariate between data chains and the multivariate of a data calling main body are realized, the multivariate co-management of data is really realized, and the transparency of government data opening is also met. The addition of the block chain technology can create a new value of data opening in public management and public service, and provide a larger development space for marketization of urban service data.
But for urban services, such as government policies, regulations on delivery, beneficial administrative permissions, etc., need to be publicly transparent. For other urban services, for example: user information and the like need to be kept secret. Further, the city service involves different government services. Therefore, in the case where such authority is complicated, if data is managed by means of a block chain, there is a conflict.
