A Comparative Study of Ethereum and Polygon for Implementing NFT-Based Certification Systems

Blockchain technology, when used to authenticate academic credentials, introduces new approaches to dealing with age-old issues like as fraud and inefficiencies. This paper informs readers on the primary roles that education-based enterprises can perform on both Ethereum and Polygon, boosting the possibilities for developing certification systems based on NFTs. Ethereum is popular among developers and has helped to formalize the sector by establishing foundations and adopting standards such as ERC721. Polygon is a Layer 2 scaling technique designed to reduce transaction costs while also improving transaction functionality. The proposed system includes steps around creating NFTs and governing their distribution and lifecycle to ensure genuine tamper proof of academic records with the help of blockchain. This paper will explore the scalability of system and its cost-effectiveness along with simplicity for ease of choosing appropriate blockchain platform for providing secure certificates issuance and verification.
