Blockchain Enabled IoT Edge Computing: Addressing Privacy, Security and other Challenges

We discussed Blockchain-enabled IoT edge computing in the earlier publication of this series, which allows any compute resource owner to join the ecosystem and lend out computer resources required for edge computing/analytics. This paper lists a possible set of challenges implementing the above solution. The primary challenges are ensuring data privacy for the input data files and ensuring computation integrity when executing the computation remotely. The paper talks about current state research and possible practical implementation to address the privacy and integrity challenges using a hardware-assisted trusted executing environment primarily Intel SGX. The paper proposes using unidirectional payment channels to address payment-related challenges.
