The DIF Hackathon 2024 brought together builders from around the world to tackle some of the biggest challenges in decentralized identity. Across multiple tracks—including education and workforce solutions, reusable identity, and privacy-preserving authentication—participants developed creative applications that redefine how digital identity is used and trusted in the real world.
One of the standout challenges? The ZKP in SSI track, sponsored by Privacy & Scaling Explorations (PSE) from the Ethereum Foundation. Teams explored how to innovate with Zero-Knowledge Proofs (ZKPs), Multi-Party Computation (MPC), and Fully Homomorphic Encryption (FHE)—leveraging programmable cryptography to enhance privacy, security, and interoperability in SSI systems.
Beyond ZKPs, this year’s hackathon saw verifiable credentials powering next-gen job boards, seamless hotel check-ins, streamlined digital identity solutions for expats, and groundbreaking innovations in decentralized file storage.
