  Pindown Certificate issuer and verifier

Inspiration

Imagine a situation where an interviewee sitting at an interview desk and presenting his certificates to the interviewers, who can't verify if it's legit (source and destination and content) and even the interviewee cannot prove if it's legit.

Verifying the authenticity of certificates has always been a problem for many individuals and institutions. Usually, they rely on third-party or own websites of issuers to verify a certificate on centralized servers. But there is no guarantee that the data won't be manipulated or erased or worst, service is taken down. In some cases, issuers use digitally signed documents. But this solution is not convenient and the maintenance of certificates is difficult.

PinDown solves this problem by storing the documents as well as their relevant ownership and verification data on the blockchain. The document itself can be stored on decentralized storage. Even if the issuer ceases to exist, the data continues to exist and can be verified. It uses wallets to sign the documents and verify sources and destinations. Also as the whole process, from document creation to transferring and verifications, happens on a single platform, it is very much convenient for users.

Now re-imagine the situation mentioned before, this time with PinDown on the desk.

What it does

Pindown is a blockchain-based document verifier. Anyone can view the legit source and destination of any certificate(or document in general). It records the document transfer data and link details on-chain such that only the issuer can specify the link to the document and receiver address and the source(issuer public key) is signed by the issuer. Anyone can also easily verify the same details through the PinDown Dapp. Verify the Authenticity of any certificate.
