Privacy-First Stablecoin Transfers: Noir and MPC in Action

In this talk, we’ll dive into the world of collaborative SNARKs—what they are, the unique challenges they tackle, and what they are used for. We’ll explore how to create private shared state, enabling private on-chain data to stay confidential while …

On Deployed vOPRFs, Nullifiers, and the World ID Infrastructure

We talk about a concrete nullifier use case in the World ID infrastructure and our efforts of designing, building and deploying a verifyable OPRF for it.

Scaling Private Iris Code Uniqueness Checks to Millions of Users

In this work we tackle privacy concerns in biometric verification systems that typically require server-side processing of sensitive data (e.g., fingerprints and Iris Codes). Concretely, we design a solution that allows us to query whether a given …

Shuffling Cards with MPC: Building a coSNARK-Powered DApp with coNoir

In this talk, we’ll dive into the world of collaborative SNARKs—what they are, the unique challenges they tackle, and what they are used for. We showcase how coNoir, a collaborative SNARK version of Noir, can be used to verifiably shuffle a deck of …
