Research on Public Participation Model Based on Block-Chain Mode: Taking Sponge City Construction as an Example

Public participation in decision-making and design is a symbol of democracy [1]. Public participation provides a more creative and suitable scheme for urban design projects [2]. However, with the emergence of some unique plans such as sponge cities and smart city projects, design companies and government could not organize effective public participation with stakeholders, like local people or computer technology companies. Some design companies know little about computer science knowledge and the demands of local people in smart city projects. So this essay would introduce new public participation based on block-chain mode. This model allows task publishers to disassemble tasks and directly releases some professional tasks to specialized technology companies, thereby achieving more efficient project cooperation. Simultaneously, in this model, the urban designer assigns the design task of community reconstruction to the community resident group, and the resident group designs their community. To achieve the goal of maximizing public participation in community reconstruction, and make community reconstruction and urban design more democratic. What’s more, this essay would also introduce how to apply it in the sponge city construction project.
