Abstract: Apparatuses, methods, systems, and program products are disclosed for smart contract-based project development using milestone based distribution. A method includes generating a smart contract, using blockchain, for a project comprising a plurality of tasks, the smart contract comprising a plurality of milestones corresponding to the plurality of tasks. The method includes posting each of the plurality of tasks to be bid on by third parties to complete each task of the plurality of tasks. The method includes associating a third party that is granted the bid for a task with the corresponding milestone in the smart contract. The method includes, in response to authenticating information evidencing completion of the task by the third party, executing a portion of the smart contract associated with the milestone corresponding to the completed task, via the blockchain, to distribute funds to the third party that completed the task.
