Gaspard Anthoine

I'm a predoctoral researcher at the IMDEA Software Institute in Madrid, supervised by Dario Fiore. My work aims to explore the limits of succinct proof systems. In more detail I'm interested in studying the trade-off between assumptions, efficiency and security guarantees one can obtain for advanced primitives like SNARKs, homomorphic signatures, vector commitments... Recently I also got interested in anonymous credentials! Feel free to email me if you want to talk about any of this.
