about this event

A 4-hour sprint: build an app that computes on encrypted data, deploy it to the Fog (the cloud that doesn't see your data), demo it, maybe win Fog credits. Fully Homomorphic Encryption (FHE) lets you compute on data while it stays encrypted. Writing it used to be impossible without a PhD. With the Niobium AI skill and our FHE domain-specific language (DSL), your coding agent handles the cryptography while you handle the idea.

Format: 6:00 · Doors, food, team-up (solo builders also welcome, we'll match you if you'd like) 6:30 · Live demo: an encrypted app built and deployed in 10 minutes 6:45 · Build sprint 9:30 · 2-minute demos 10:00 · Winner announced, hang out

Prizes: 🏆 Best build: one month of the Fog Team plan ($1,000 in credits) 🎖 Everyone who demos: $200 in Fog credits 🎟 Everyone who attends: $100 in Fog credits

Details: Limited to 40 builders, applications reviewed on a rolling basis. Selected participants get venue details one week out. Food & drinks provided. Bring a laptop and your favorite coding agent.

Before you come: 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

Ground rules: You must be 18 or older to participate. The winner is 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, or come with something you build ahead of time and iterate. Open-source libraries and public APIs are fair game. 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 night to share what got built. Registering means you're OK appearing in them; tell an organizer if you'd rather stay out of frame.
