This system enables manufacturers to create certifications and allows consumers to verify them using QR codes. I demonstrate the process of creating a certificate and simulating the verification by scanning the QR code, which retrieves and validates the certification instance. You can see how the system effectively manages both the creation and verification of certified products. I encourage you to explore the capabilities of this system."}
