Abstract In the present case scenario, the issue of counterfeit and altered certificates has been a big challenge in the field of education and employment. Forged physical certificates are used by many individuals to get employment or admission into institutions and this harms the reputation of the institutions and gives employers trust problems. To deal with this escalating issue, the project Detection of Fake Physical Certificates using a blockchain-based Certificate Verification System proposes a safe and transparent solution in the form of blockchain technology. A certificate is saved on a blockchain and has a distinct hash and a QR code, which allows easily checking its authenticity and is impossible to manipulate and copy. The system enables institutions to publish verified certificates, allows the holders to share and employers or verifiers to access their validity instantly by scanning the QR code. As everything is stored in blockchain which cannot be tampered with, it guarantees the maximum transparency and reliability to the verification. This solution will help create a trust between all parties and guard the organizations against the dangers of certificate fraud in the digital era.
