Many diverse sectors rely on the Industrial Internet of Things (IIoT), and here individuals are working to establish a standard, secure, and scalable IIoT infrastructure that can be used by all of these sectors. No current method for IIOT systems can provide reliable, accurate services since they are all vulnerable to malicious attacks and single points of failure. We include a blockchain mechanism into the IIOT system for security reasons, which has sparked a lot of interest in this next stage. Unfortunately, blockchain technology isn't ideal for low-power Internet of Things devices because of its high power consumption and poor performance. In this article, we provide a new credit-based Proof of work method for Internet of Things (IoT) devices, which allows us to tackle a number of issues by implementing a new safe system with a credit-based consensus process for Biotin. System security and efficient transactions are guaranteed by this suggested method. We provide a un
