Regarding such application scenarios and the requirement to securely disseminate the collected data, we present a fog computing architecture that integrates blockchain technology for privacy aware data sharing. The latter fog-blockchain prototype is based on a private, permissioned blockchain paradigm. We discuss a lightweight implementation of our proposed integrated fog node architecture using Hyperledger Fabric as blockchain with a peer-to-peer network among cheap single-board-computers as basic data collecting peers. Furthermore, we investigate the computing and network performance indices of our prototypical lightweight fog computing architecture.engInternet-of-ThingsFog computingSmart homeBlockchainHyperledger fabricconferenceobjecturn:nbn:de:bvb:473-irb-114836x
