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.

适用于IIoT的基于安全，灵活的基于FPGA的区块链系统

区块链是工业4.0的有希望的解决方案；但是，它不能保证输入数据的完整性。我们为工业物联网提出了一种基于现场可编程门阵列（FPGA）的私有区块链系统，其中事务生成是在FPGA内部以隔离和隔离的方式执行的。
