about this event

One day. Encrypted data. Your AI coding agent and Niobium's tools handle the cryptography.

Fully Homomorphic Encryption (FHE) lets you compute on data while it stays encrypted, with no decryption at any point. It used to take a PhD to write. Now it takes a description.

You'll build with the Niobium AI skill and our FHE domain-specific language (DSL), a small programming language made for encrypted computation. Describe what you want, let your coding agent handle the FHE parts, and deploy to the Fog, the cloud that doesn't see your data. No cryptography background required. If you can vibe code, you can ship an encrypted app in an afternoon.

Prizes 🥇 1st place: a year of the Fog Developer plan ($2,400 in credits) 🥈 2nd place: 6 months of Fog Developer ($1,200 in credits) 🥉 3rd place: 3 months of Fog Developer ($600 in credits) ⚡ Every shipped demo: $100 in Fog credits 🎟 Everyone who attends: $100 in Fog credits

Before event day Come ready to build: AI skill: github.com/NiobiumInc/niobium-skills FHE domain-specific language (DSL) + Niobium client: github.com/NiobiumInc/niobium-client Set up a Niobium Fog account: https://console.niobium.co/request-account Judges: To be announced…

Ground rules You must be 18 or older to participate. Winners are chosen by Niobium judges based on what you build: a working demo, originality, and the quality of your ideas and edge cases. Build it during the event. Open-source libraries and public APIs are fair game; anything pre-built must be called out in your demo. You own everything you build here. Prize and attendance credits follow the Fog platform terms. They expire (we'll tell you exactly when), and they have no cash value. We'll take some casual photos during the day to share what got built. Registering means you're OK appearing in them; tell an organizer if you'd rather stay out of frame.
