Abstract: In this digital world, everything is digitalized but still, some practices are a bit unvarying, one of those is the certificate verification process. The foremost important documents are certificates for graduates from universities and other educational institutions. However, it is costly and time-consuming to check certificates using traditional methods. This paper aims to introduce a theoretical model, which can give the possible infusion for the issue and verification process of any type of document. We need to consider strong points on blockchain apart from finance, those are tracking, supply chain, etc. In this model, we are using blockchain and distributed storage. There are many functions such as hash, public and private key cryptography, digital signatures, peer-to-peer networks and work evidence in blockchain technology. In This model, we are using IPFS for distributed storage (peer-to-peer) everything in ipfs is globally available with the appropriate hash generated by ipfs, for this reason, we added multi-layer security at the Client-side, as an encryption mechanism. To Protect the documents uploaded by the issuer, we enabled an encryption mechanism at the client This Dapp (decentralize) has been divided into two parts one is the document issuer and the other one is the verifier.
