Pi Network has built the world’s most widely distributed cryptocurrency with over 35 million members across the globe. The project’s next mission? To expand the app platform to a robust utilities-based ecosystem. That’s where you come in: the CT challenges the community to build a mobile web app that brings true value to the user whether that be entertainment, education, social interaction, access to information, etc.

The submission project should address a real user need, and be intuitive to use and accessible to everyday people. Additionally, apps should support the use of Pi cryptocurrency, either as an optional feature or as a core functionality.

The Original Pi Whitepaper was published on PiDay, March 14, 2019. While our original vision remains unchanged, the details of this whitepaper are not fully up to date. On December 28, 2021, along with the release of the Enclosed mainnet, we published three draft chapters of the Updated Pi Whitepaper, detailing the Pi token token model and mining mechanism as well as the project’s roadmap.
