Abstract: A decentralized system for issuing digital certificates to users and authenticating such users is provided. A certificate issuer system may verify a user and issue a digital certificate to the user. The certificate issuer system may also calculate authenticity information relating to the digital certificate and cause the same to be recorded in a distributed ledger system, for example, in the form of a smart contract. When the user attempts to access a cloud application, the application receives the digital certificate, calculates second authenticity information relating to the certificate, and compares the calculated authenticity information to that recorded in the distributed ledger system. Upon a determination that the calculated and recorded authenticity information match, an authentication confirmation may be generated and the user may be permitted to access the cloud application.
