ChainComm: A Framework for Future Communities Based on Blockchain

With the acceleration of urbanization and the intensification of the development momentum of smart cities, the concept of smart communities is increasingly being mentioned. And the operation of smart communities is often accompanied by huge data flow and sharing, which has troubled the data security belt in smart communities. And blockchain provides a good solution to solve the problem of data sharing security. Blockchain has tamper-evident, transparency, and traceability, which can effectively protect and track data flow and ensure that the data has not been tampered with. This paper aims to propose a decentralized smart community system architecture based on blockchain technology to comprehensively optimize trust-based smart city applications for all community-building stakeholders and service models.
