Open-source bounty

An open-source bounty is a monetary reward for completing a task in an open-source software project.

Description
Bounties are usually offered as an incentive for fixing software bugs or implementing minor features. Bounty driven development is one of the business models for open-source software. The compensation offered for an open-source bounty is usually small.
