Velox: Scalable Fair Asynchronous MPC from Lightweight Cryptography

본문 미리보기

Multi-party computation (MPC) enables a set of mutually $n$ distrusting parties to compute any function on their private inputs. Mainly, MPC facilitates agreement on the function’s output while preserving the secrecy of honest inputs, even against a subset of $t$ parties controlled by an adversary. With applications spanning from anonymous broadcast to private auctions, MPC is considered a cornerstone of distributed cryptography, and significant research efforts have been aimed at making MPC pra
