Blockchain Based Documents Verification System [ run the project ]

(first of all sorry about the video quality )
The system is complete and running on a real Blockchain currently on Polygon Blockchain
can be used to export students documents and give the degree to the students as a PDF file and QR-Code
whenever the students want to check the authenticity of their degrees for companies from anywhere they just scan the qr-code or upload their PDF degree to the system and check it .
