+
+## Introduction
+
+**Minimal Anti-Collusion Infrastructure (MACI)** is an open-source public good that serves as infrastructure for private on-chain voting.
+
+MACI is an application that allows users to have an on-chain voting process with greatly increased collusion resistance. A common problem among today’s on-chain voting (or public good funding) processes is how easy it is to bribe voters into voting for a particular option. Since all transactions on the blockchain are public by default, without MACI, voters can easily prove to the briber which option they voted for and therefore receive the bribe rewards.
+
+MACI counters this problem by using encryption and zero-knowledge proofs (zk-SNARKs) to essentially hide how each person voted while still publicly revealing the final vote result. User’s cannot prove which option they voted for, and therefore bribers cannot reliably trust that a user voted for their preferred option. For example, a voter can tell a briber that they are voting for option A, but in reality they voted for option B. There is no reliable way to prove which option the voter actually voted for, so the briber has less incentive to pay voters to vote their way.
 
 Applications like [clr.fund](https://clr.fund/) build atop MACI to increase

For a general overview, the history and the importance of MACI, see [Release Announcement: MACI 1.0](/blog/maci-1-0-release) by Wei Jie, one of the creators. He also created a helpful [overview of MACI video](https://www.youtube.com/watch?v=sKuNj_IQVYI). Kyle Charbonnet wrote a great [Technical Introduction to MACI 1.0](/blog/maci-1-0-technical-introduction) that provides a walkthrough on how MACI operates.
