Degree/Experience certificate verification system using block chain

Abstract

Blockchain is a new emerging technology which has received great attention in recent years. It is a global online immutable and transparent database which anyone and anywhere with an internet connection can access. The feature that makes it unique is its decentralization. This means the blockchain ledger is shared among all computers around the world, if it is built on public platform, not in one central location. The above discussed features of blockchain i.e. immutability, transparency and decentralization are considered very important in many fields e.g. Maintaining Patient Record, Supply Chain Management, Automotive Industry and Asset Transfer. This Project, Certificate Verification System is web based Certificate verification service providing one-step verification with multiple options. Verification can be done using student’s Digital Certificate by uploading it on the Web portal, generating hash, comparing the hash with the hash of the original certificate stored on blockchain ledger and showing the status. The service can be used by Employers, Placement Consultancies, Colleges and Universities, and other similar organizations. All this process is done by writing a Smart Contract. as this application is being built on a public platform so we used Ethereum.
