With the development of technology, big data applications have gradually penetrated the scope of smart cities.Therefore, building a new type of Smart City is essential to optimize the national governance system and its capacity.That requires the cooperation of all government sectors to form a positive incentive mechanism for information sharing.However, the massive amount of social operations data raises several issues, such as data islands, inconsistent data standards, data privacy, and security to smart city data governance.Hence, this paper proposes a data collaborative governance method based on blockchain and secure multi-party computing in a trusted execution environment, and incorporates it in designing a data-sharing platform for Smart Cities.The results of pressure tests showed that the functions of each module could operate normally, which were aligned with expectations.This design enables innovative urban governance and alleviates the security and privacy issues in traditional Smart Cities.Therefore, the proposed platform stands highly promising for optimizing data governance in Smart Cities.
