Blockchain is a promising solution for Industry 4.0; however, it does not guarantee input data integrity. We propose a field-programmable gate array (FPGA)-based private blockchain system for the industrial Internet of Things, where the transaction generation is performed inside the FPGA in an isolated and enclaved manner.
