In this talk, we dive into the world of collaborative SNARKs, what they are, the unique challenges they tackle, and what they are used for. We explore how to create private shared state, enabling private on-chain data to stay private while still …
In this talk we present Merces2, a method of shielding ERC20 tokens to gain privacy using MPC and Collaborative SNARKs. It allows to hide user balances, as well as sender, receiver and transaction amounts when shielded tokens are transferred. …
Fungible tokens on public blockchains expose all balances and transfer amounts in the clear, which is incompatible with the financial privacy required by many real-world applications. We present Merces a confidential token contract that hides user …

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.
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 …
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 …

In this talk we present collaborative SNARKs and why they are needed. Furthermore, we present our co-circom library, a rust library allowing to create a coSNARK from circuits written in Circom. Finally, we show how to apply co-circom to an on-chain …
