The invention discloses a smart city data sharing system and method based on a block chain. Urban road satellite images and road condition broadcast information are collected and stored in a traffic data unit of the smart city data module. Power market transaction information is collected and stored in a power data unit of the smart city data module; air indexes and urban gaseous pollutant generation information are collected and stored in an ecological data unit of the smart city data module; and the current urban road satellite image and the road condition broadcast information are updated to a traffic data unit through a data updating module according to the set frequency, the current electricity market transaction information is updated to an electricity data unit, and the current airindex and the urban gaseous pollutant generation information is updated to an ecological data unit. According to the method, the block chain technology and the data sharing technology are combined, sothat a user does not need to worry about privacy leakage after querying, and it is guaranteed that query records cannot be tampered.

    本发明公开了一种基于区块链的智慧城市数据共享系统及方法,采集城市道路卫星图像和路况播报信息并保存至智慧城市数据模块的交通数据单元中,采集电力市场交易信息并保存至智慧城市数据模块的电力数据单元中,采集空气指数和城市中气体污染物产生信息并保存至智慧城市数据模块的生态数据单元中,根据设定频率,通过数据更新模块将当前城市道路卫星图像和路况播报信息更新至交通数据单元,将当前电力市场交易信息更新至电力数据单元,将当前空气指数和城市中气体污染物产生信息更新至生态数据单元;本发明利用区块链技术与数据共享技术结合,使用户在进行查询后不用担心隐私的泄露问题,而且保证了查询记录的不可篡改。
