Standardization of Blockchain-based I2oT Systems in the I4 Era

In Industry 4.0 (I4), the Industrial Internet of Things(I2oT) data streams are prone to significant data manipulationrisks. The integration of Blockchains (BC) with I2oT may becomea solution preventing from this problem. This paper provides ablockchain agnostic Blockchain I2oT (BI2oT) architecture calledBIIT that allows developing a broad range of BC applicationsfully integrating Internet of Things (IoT). The mechanismsintroduced in BIIT aim at solutions that provide data reliability,limit the computational overhead, and enhance energy efficiency.BIIT is evaluated through real-world experimentation.
