Join Proof of Concept, a 6-week virtual startup competition to create mobile apps that prove anything online, securely and undeniably. From verifying your gaming skills or concert attendance to tracking exercise habits or medical history, we’re looking for innovative ideas that leverage verifiable data to build trust.
No coding expertise required! Bring a bold idea, and XION’s beginner-friendly tools will help you make it real. Basic coding knowledge is a plus, but creativity and impact are what matter most.
Build mobile apps that use verifiable data to create trust in new ways. Examples include:
Proving online activity (e.g., social media views, downloads, or Uber rides)
Verifying personal achievements (e.g., gaming stats, fitness goals, or concert visits)
Enhancing trust in critical data (e.g., medical records, financial status)
Validating AI-generated content or other internet sources
We want unique, practical, and scalable ideas that redefine how we trust information online.
