Abstract
Systems and methods as described herein may include creating and monitoring workflows in a blockchain network. A workflow may be implemented by using a smart contract or the steps in the workflow may be recorded in a distributed ledger in a blockchain network. Completion of a workflow step may be verified by identifying a blockchain transaction executed by the workflow step performer assigned to the workflow step. The blockchain transaction is associated with encryption keys of the workflow step performer assigned to the workflow step. The completion of the execution of a workflow may be verified by determining whether the status of the last workflow step is complete, and identifying a blockchain transaction associated with encryption keys of the workflow step performer assigned to the last workflow step.
