BLOCKCHAIN ACCESS CONTROL SYSTEM

A system may receive a credential token and an access command. The access command may identify access logic to modify a datablock stored in a blockchain. The credential token may be mapped to a role token included in a role-based access control model. The system may determine a role-based access control framework authorizes the access command by identifying an authorization token in the role-based access control model, and the system may determine the role token is mapped to the identified authorization token in the role-based access control model. The system may determine the datablock includes the identified authorization token. The system may validate the identified authorization token. The system may authorize execution of the access logic to modify the datablock in response to the access command being authorized by the role-based access control framework, and validation of the identified authorization token included in the datablock.
