Abstract :

The use of blockchain technology is a game changer in improving the security and transparency of verifying documents and likewise in enhancing efficiency for such processes. The paper proposes a document-verification system using technology on the Polygon Blockchain: an environment-friendly Layer 2 solution on the Ethereum platform. The system is aimed at addressing issues such as document tampering, forgery, and inefficiencies in traditional verification methods by offering them in a secure and transparent environment. The validation process for several documents, such as academic certificates, legal contracts, and identity proofs, is assured to be cost-efficient in view of the low fees and fast processing time offered by Polygon. Also, the actual verification process is automated through smart contracts, which removes the need for an intermediary to establish trust. In addition, state-of-the-art cryptographic methods are integrated into the system to keep document hashes secure, thereby ensuring data integrity and confidentiality. It is this research that showcases how polygon blockchain technology can introduce a transformation in document verification, providing a secure and user-friendly solution for individuals and businesses alike
