Current certification systems suffer from various problems such as vulnerability to fraud, time-consuming verification processes, delays in obtaining certificates, limited access due to geographical limitations, high costs, outdated content, lack of flexibility, credibility concerns, quality control issues, technical difficulties, limited interaction, limited feedback, and barriers to access. To address these problems, we propose a solution in the form of Certifier Dapp, a decentralized application built on the Ethereum blockchain. The Certifier Dapp leverages the MetaMask wallet for authentication and communication with the blockchain and offers functionalities such as issuing new certificates, updating issued certificates, verifying certificates, and tracking change history. Utilizing blockchain technology, the Certifier Dapp ensures data integrity, immutability, transparency, and security. The proposed solution aims to provide a seamless and efficient certification process, overcoming the limitations of current certification systems and making certification more accessible and credible for users.
