Decentralized Certificate Verification Application via blockchain-A Review

With an increase in demand for online education and online services in general, there has also been an increase in the move from doing things in the traditional manner to doing things online. The market for online certifications is one of these "online services" key segments. The importance of certificates in the online world has increased significantly, whether they are issued by educational institutions or corporate businesses that may need to validate the competence of their staff. The worry about confirming the authenticity of the certificate itself is growing along with the need for online certification technologies. Since the blockchain network uses distributed ledger technology and each block of data contains a cryptographic hash of the previous block, we plan to use it to apply this certification technology in our project.
