Certificate Validation Using Blockchain

Abstract

As education becomes more diversified, decentralized and democratized, we still need to maintain reputation, trust in certification and proof of learning. Nowadays everyone has to show his/her Document and Certificate to any other person for some purpose/job. After seeing the document, the 3rd person cannot validate the originality of the certificate. The same thing is applied for a land registry, PAN card, and Aadhar card verification. The increased focus on relevance and employability may also push us in this direction, as we also need more transparency. We can solve this problem or get trust by using blockchain technology. The digital currency Bitcoin is probably the best-known application of blockchain and is even better known than the Blockchain technology on which it is based [1]. The blockchain is a chain of blocks and blocks are immutable in a distributed environment, in which storage devices are not all connected to a common processor. It is a database of records/public ledger of all transactions/digital events that have been performed and information is shared within participating parties. Each entry in the system is verified by common consent of the participants in the system. Once information is entered in the blockchain it cannot be erased. It could provide a system that is transparent and secure. Blocks (Ordered Records) are added to the blockchain with timestamp and a link to a previous block. Verifying a diploma/certificate today takes a good amount of time and requires human resources or human resources to request confirmation of details from universities.
