The Pi Commerce Hackathon, starting on Feb 1, 2024, aims to develop a commerce app for local offline businesses to accept Pi as payment. CT encourages developers with a prototype app, and the winning app will be announced on Pi Day, Mar 14, 2024. Requirements include using Pi SDK for payments, and the app must not charge with non-Pi assets or fiat currencies. The hackathon is seen as preparation for the Mainnet launch, emphasizing Pi as a long-term currency. Concerns are raised about low Pi prices potentially impacting the Pi Network ecosystem negatively.
