Digital certificates serve as essential cryptographic tools in securing online transactions and communications by verifying the identities of parties involved. The main goal of this project is to make digital certificates more secure using blockchain technology. Digital certificates are important for verifying things like education degrees, medical records, and financial transactions. However, current methods can be vulnerable to fraud and tampering. We use blockchain technology, which is a decentralized and tamper-proof system. Digital certificates will be stored on the blockchain, making them impossible to alter. Smart contracts will automate the verification process, making it faster and more reliable. By using a decentralized approach, we can eliminate single points of failure and make the whole system more trustworthy. In the future, we'll expand the system to handle different types of certificates and work on making it compatible with existing systems. We'll also research ways to make the blockchain system work for large-scale use. Continuous improvements will be made to keep up with changes in technology and security threats.
