Abstract: A method, computer system, and computer program product are provided for managing tasks of employees within a blockchain-based workflow system. A workflow transaction associated with a workflow stage is received from an employee. The workflow system records the workflow transaction in a workflow blockchain. Based on a smart contract recorded within the blockchain, the workflow system determining a role for the employee is authorized to perform the transaction. If authorized, the workflow system executes a set of resulting transactions indicated by the smart contract and updates at least one condition for completion of the workflow stage. When the workflow system determines that all conditions indicated in the smart contract have been completed, the workflow system finalizes the workflow stage and advances the workflow to a subsequent stage.

Abstract: A method, computer system, and computer program product are provided for controlling access to a licensed software application. A blockchain-based version control system receives an access request from a user that requests access to the licensed software application. The version control system determines whether a user has accepted license terms for a current version of the licensed software application by querying a version control blockchain. Responsive To determining that the user has not accepted the license terms for the current version of the licensed software application, the version control system presents the user with a clickwrap agreement requiring the user to accept license terms for the current version of the licensed software application. Responsive to receiving acceptance of the license terms from the user, the user's acceptance of the license terms for the current version of the licensed software application is recorded in the version control blockchain.
