The Pi Network has announced the Pi Hackathon 2025, inviting developers to register and form teams starting August 15. The event, aimed at expanding the PI ecosystem, encourages the creation of tools and apps that enhance the token's usability. The hackathon will commence on August 21, with final submissions due by October 15. A total prize pool of 160,000 PI tokens will be awarded to up to eight teams, with the top team receiving 75,000 PI. Developers are urged to incorporate AI tools and adhere to Mainnet Listing Guidelines. Participants must complete Pi KYC to claim prizes, despite some controversy surrounding the process. Apps will be judged on PI utility, UI/UX, long-term potential, and community alignment.
