Taiko and DoraHacks are jointly launching the largest-scale MACI community vote event in the Ethereum ecosystem

On January 28th, the Ethereum Layer 2 network Taiko successfully held its first online hackathon and partnered with DoraHacks to launch the largest-ever anonymous community vote. The number of participants in this vote exceeded 920,000, making it the largest on-chain vote using MACI technology within the Ethereum community. Taiko's Grant Factory hackathon motivated developers to come up with and design innovative solutions, interesting applications, or projects with positive social impacts. After months of hard work, the finalists have submitted their final votes, marking a significant step towards more community-driven decision-making. Minimal Anti-Collusion Infrastructure (MACI), initially put forward by Ethereum co-founder Vitalik Buterin, is a voting mechanism that utilizes zero-knowledge proofs to provide privacy protection and anti-collusion for the community. Focusing on the flaws in traditional voting systems such as fraud, collusion, and lack of privacy, a method to address these issues on-chain was proposed. MACI uses zero-knowledge technology to ensure that votes remain encrypted, maintain the integrity of the vote, and prevent vote-buying or coercion. In a MACI voting round, there are two roles: the operator and the user. Users submit encrypted votes on-chain to the MACI smart contract. All votes have on-chain timestamps, and only the operator can view the vote contents. The results are published by the operator after the vote ends.
