Research on Blockchain Privacy Computing Technology for End-edge-cloud Collaborative Architecture

With the continuous integration of technologies such as the Internet of Things, 5G, big data, cloud computing, and edge computing, a end-edge-cloud collaborative computing model has gradually formed. Integrating blockchain into the end-edge-cloud collaborative architecture can effectively make the data between edge-cloud nodes interact with each other in trust, and ensure the integrity and availability of data. However, due to the transparent nature of blockchain ledger data, which may cause privacy data leakage in the end-edge-cloud, in order to solve the problem that the data provider does not disclose the original data, the "usable invisible" of the data is realized. This paper takes privacy computing technology as the research object, summarizes the existing research results, proposes to construct a trusted computing framework based on blockchain smart contract as the end-edge-cloud architecture, and integrates privacy computing technology to break the "data island" and realize the security protection of private data.
