Systems and methods for accessing credentials from a blockchain are provided. A computing device requests for a server to process a transaction. In response to the request, the server transmits a server public key to the computing device. A key generator of the computing devices uses the user private key and the server public key to generate a user public key. The user public key includes permissions to access credentials that are stored on blockchain. The server receives the user public key and generates a request for credentials to blockchain. The request includes the user public key and the server private key. The blockchain receives the request and generates an identity token. The identity token includes credentials that are specified in the user public key. The blockchain transmits the identity token to the server and the server uses the identity token to processes the transaction. Link to Full Patent
