## Description

Wei Jie from the Ethereum Foundation gives a beginner-friendly intro to Minimum Anti-Collusion Infrastructure (MACI).

MACI enables Ethereum developers to create voting systems where collusion among participants is difficult, while retaining the censorship resistance and correct-execution benefits of smart contracts. In this presentation, Wei Jie describes real-world problems that MACI is intended to solve, provide an accessible explanation of how MACI works, and describe challenges and future work to be done.

Koh Wei Jie is a software developer specialising in privacy and zero-knowledge proofs in decentralised systems. He is part of the Applied ZKP team at the Ethereum Foundation, where he has worked on Semaphore, a privacy gadget which enables anonymous signalling for voting and authentication applications. He also built Minimal Anti-Collusion Infrastructure, a framework for bribery-resistant and privacy-preserving elections.
