Certificate Management System Using Blockchain

Abstract

AbstractOvercoming the problems of existing file storage and sharing approaches, this paper gives an efficient way of storing and sharing the files using blockchain and smart contracts. As an example, Managing student’s information and sharing them or giving access to unauthorized people in a much secured way is one of the major responsibilities of any university or organization. Instead of storing the certificates in a normal database, blockchain technology can be used to store the certificates. In our approach, the certificates and other documents will be uploaded to the blockchain and will be shared securely when any third party needs to access the certificates. The university administrator has ultimate rights to upload student’s certificates and managing them. Students can view their documents and certificates; other unauthorized people (third party/organization/employer/others) can access the files after taking permission of the college administrator. These types of approaches are very useful in this era where efficient storage and sharing the files plays a crucial role. The feature which differentiates our approach of certificate management system from existing certificate management system is, our system is decentralized, cryptographically secure, immutable and efficient.KeywordsBlockchainCryptocurrencyDistributed ledgerNode applicationConsensusEthereumSoliditySmart contracts
