With today’s rapid urbanization, global cities are constantly expanding to accommodate population growth. It is estimated that global cities will add another 2.5 billion new residents by the year 2050. However, along with this rapid expansion also arises the need for cities to provide infrastructure support in order to provide their residents with a good quality of life that is both sustainable and environmentally friendly by reducing the carbon footprint. Digital technology can be harnessed to help cities manage their energy needs through the deployment of the smart grid. Blockchain provides a more secure management of energy data while satisfying the energy needs of a smart city of the future. Blockchain aggregators can be deployed at different layers of the smart grid to protect the data flowing on the network. With the increasing popularity of microgrids as components of the smart grid, ‘prosumers’ can use the blockchain to sell their own renewable energy back to the smart grid. The blockchain technology platform can be deployed to protect microgrid data resulting in a more secure power grid system, a necessity to keep today’s digital cities operating cost-effectively, efficiently, and securely.

随着当今快速的城市化进程，全球城市正在不断扩展以适应人口增长。据估计，到2050年，全球城市将再增加25亿新居民。但是，伴随着这种快速增长，城市也需要提供基础设施支持，以为其居民提供良好的生活质量。通过减少碳足迹来实现可持续发展和环境友好。可以利用数字技术通过部署智能电网来帮助城市管理其能源需求。区块链提供了更安全的能源数据管理，同时满足了未来智慧城市的能源需求。可以将区块链聚合器部署在智能电网的不同层上，以保护网络上流动的数据。随着微电网作为智能电网的组成部分的日益普及，“生产者”可以使用区块链将自己的可再生能源卖回智能电网。可以部署区块链技术平台来保护微电网数据，从而建立更安全的电网系统，这是保持当今数字城市经济高效，高效且安全地运行的必要条件。
