Blockchain-based workflow system

A computer system comprising:

• a hardware processor;
• and
• a blockchain-based workflow system in communication with the hardware processor, wherein a blog chain workflow system is configured:
• to receive a workflow transaction from an employee, wherein the workflow transaction is associated with a first stage of the workflow;
• to record the workflow transaction in a workflow blockchain;
• to determine whether a smart contract authorizes a role for the employee to perform the workflow transaction, wherein the smart contract is recorded within the workflow blockchain;
• responsive to determining that the role is authorized to perform the transaction, to execute a set of triggered transactions indicated by the smart contract and updating at least one condition indicated in the smart contract for completion of the first stage of the workflow;
• to determine whether all conditions indicated in the smart contract for completion of the first stage of the workflow have been completed;
• and
• responsive to determining that all conditions indicated in the smart contract have been completed, to finalize the first stage of the workflow and advancing the workflow to a second stage,
• wherein in finalizing the first stage of the workflow, the blockchain workflow system is further configured:
• to collect the workflow transaction and the set of triggered transactions into a workflow block for the first stage of the workflow;
• to attach the workflow block to a local copy of the blockchain;
• and
• to publish the workflow block to the blockchain-based workflow system.

A computer program product for managing tasks of employees within a blockchain-based workflow system, the computer program product comprising:

• a computer readable storage media;
• program code, stored on the computer readable storage media, for receiving a workflow transaction from an employee, wherein the workflow transaction is associated with a first stage of the workflow;
• program code, stored on the computer readable storage media, for recording the workflow transaction in a workflow blockchain;
• program code, stored on the computer readable storage media, for determining whether a smart contract authorizes a role for the employee to perform the workflow transaction, wherein the smart contract is recorded within the workflow blockchain;
• program code, stored on the computer readable storage media, responsive to determining that the role is authorized to perform the transaction, for executing a set of triggered transactions indicated by the smart contract and updating at least one condition indicated in the smart contract for completion of the first stage of the workflow;
• program code, stored on the computer readable storage media, for determining whether all conditions indicated in the smart contract for completion of the first stage of the workflow have been completed;
• and
• program code, stored on the computer readable storage media, responsive to determining that all conditions indicated in the smart contract have been completed, for finalizing the first stage of the workflow and advancing the workflow to a second stage,
• wherein the program code for finalizing the first stage of the workflow further comprises:
• program code, stored on the computer readable storage media, for collecting the workflow transaction and the set of triggered transactions into a workflow block for the first stage of the workflow;
• program code, stored on the computer readable storage media, for attaching the workflow block to a local copy of the blockchain;
• and
• program code, stored on the computer readable storage media, for publishing the workflow block to the blockchain-based workflow system.
