Benedikt Bünz : Bulletproofs

Benedikt Bünz (https://crypto.stanford.edu/~buenz/) spoke about Bulletproofs. Benedikt is a PhD student in the Applied Cryptography Group at Stanford. Bulletproofs are short non-interactive zero-knowledge proofs that require no trusted setup. A bulletproof can be used to convince a verifier that an encrypted plaintext is well formed. For example, it can prove that an encrypted number is […]
