ABSTRACT
In today's digital era, the reliance on digital certificates has grown significantly across various domains, including education, professional certifications, and identity verification. However, traditional certificate verification methods often face challenges related to authenticity, centralization, and susceptibility to forgery. This study addresses these issues by leveraging blockchain technology, which offers a decentralized and tamper-proof approach to certificate verification.The problem addressed in this study is the lack of a robust and secure certificate verification system that ensures the authenticity and integrity of digital certificates. Existing centralized methods are vulnerable to attacks and data manipulation, undermining the credibility of the entire certification process. To overcome these challenges, this study proposes a web-based system that utilizes blockchain as a distributed ledger to record and validate certificate data transparently and immutably. By doing so, it ensures that certificates cannot be tampered with, and their legitimacy can be easily verified by relevant parties.For the implementation of the proposed web-based digital certificate verification system, a popular programming language such as Solidity is used.Solidity is specifically designed for developing smart contracts on blockchain platforms like Ethereum, making it an ideal choice for building secure and efficient certificate verification mechanisms. By employing Solidity, the system can create and manage smart contracts responsible for recording and validating certificate data on the blockchain, thereby ensuring a reliable and decentralized verification process.The web-based digital certificate verification system using blockchain technology addresses the current challenges in digital certificate verification, offering a secure, tamper-proof, and transparent solution. By leveraging Solidity and blockchain, the system enhances the trust and credibility of digital certificates, enabling secure interactions in various domains.
