Open business model in MEC is conductive to resources sharing of consumer electronic products. However, there are risks in the process of business mode opening , such as, the protection and smart management of data and knowledge flow. Based on the blockchain, smart contract and DAC (Distributed Autonomous Corporation) technologies, we propose the Blockchain-based business model (called BM-ICB) of open innovation strategy for smart edge data flow. Based on the DPoS consensus mechanism of blockchain technology, we research the smart and dynamic management mechanism to realize the detection, monitoring and classification of enterprise behaviors of consumer electronic products, besides, the interaction process between the users and Consortium chain is improved through the DAC technology. The theoretical analysis estimates strong security and high performance of the BM-ICB model, and the experimental evaluation testifies the high performance.
