About the Project – BitID 🚀 Inspiration As decentralized technologies continue to evolve, one thing remains stubbornly centralized: identity verification. From government IDs to university degrees, identity is still managed by siloed entities with limited interoperability and zero user sovereignty.

We were inspired to create BitID — a self-sovereign identity verification system built on Bitcoin — to reimagine how users store, share, and verify credentials. Our goal was to bring sleek, modern design (think Coinbase UX) to the trust layer of the decentralized web.

🛠️ How We Built It We built BitID in under 24 hours, focusing on clean UX and forward-compatible architecture. Here’s how:

Frontend: Built with React, styled with TailwindCSS, and structured with component-based design for scalability.

Identity Flow: Users can upload and manage credentials like:

Email verification

Government-issued ID

Proof of Address

University Degree

Mocked Integrations: To align with key prize tracks, we simulated future support for:

⚙️ exSat – modular smart contract framework

💱 sBTC – enabling identity-backed Bitcoin utility

📊 Rebar Data – bringing in off-chain data to enrich identity proofs

Backend: Mocked API endpoints and credential validation logic to simulate production flow.

💡 What We Learned How identity systems can be rebuilt on Bitcoin while preserving privacy and user ownership

The value of designing for modularity, with future integrations like exSat and sBTC in mind

How to prioritize UX and trust in blockchain-based apps, especially around onboarding

⚔️ Challenges We Faced Time Constraint: This was a 1-day sprint, so real backend integration wasn’t feasible — we focused on mocking the functionality in a way that could be replaced easily post-hackathon.

Complex Ecosystem: Integrating Bitcoin-native tools like exSat and Rebar Data requires deep technical consideration — we studied their potential and designed our architecture to accommodate them in the future.

UX Balancing Act: Merging seamless user experience with decentralized tech is always a tightrope — but BitID finds a strong middle ground.

🎯 What’s Next? We plan to:

Replace mocked systems with live APIs and smart contract interactions

Build real Bitcoin transaction logic for identity-backed usage (e.g., DAO access, BTC paywalls)

Integrate decentralized revocation and multi-sig credentials
