Module 5: Blockchain Integration with Industrial IoT and OT Systems

Deploy edge computing gateways that batch and sign IoT sensor data before blockchain submission to reduce network load.
Configure firewall rules to allow outbound blockchain transactions from OT networks while blocking unauthorized inbound traffic.
Implement secure boot processes on IoT devices to ensure firmware integrity before blockchain participation.
