What are Public Goods?​

Public goods are services or products that are available for everyone to consume, regardless of whether they contribute to their creation. Examples include clean air, public parks, and open-source software. These goods are essential for community welfare but often face funding challenges due to their non-excludable and non-rivalrous nature. This is where blockchain technology steps in, offering a decentralised approach to funding these vital initiatives. Through blockchain, transparency and community participation in funding decisions are greatly enhanced.

What is MACI and how does it help fund Public Goods?​

At its core, MACI is a tool that ensures privacy and prevents collusion in voting and decision-making processes. This function is crucial in public goods funding scenarios, as it ensures that the allocation of funds is fair and uninfluenced by external factors.

Current state​

MACI can be used in different forms of decision making and voting.

Quadratic funding is one of the ways in which we could utilise MACI for public goods funding. Quadratic funding is a democratic mechanism for crowdfunding that seeks to promote equitable, inclusive funding for public goods such as open-source software, scientific research, and public art initiatives. By incorporating MACI, these platforms guarantee that votes on how funds are distributed are not swayed by bribery or external pressures. This approach ensures a democratic and equitable distribution of funds, leading to more effective and genuinely representative support for public goods.

Another way in which MACI is utilised is for communities to be able to vote in Retroactive Public Goods Funding (RetroPGF) rounds. For example, Optimism runs RetroPGF rounds which involve allocating funds to projects based on past contributions to the ecosystem, incentivising and rewarding valuable contributions retrospectively. We’ve incorporated MACI to the RPGF stack and thus communities would be able to independently run future rounds in a private and secure manner using maci-rpgf!

The Future looks bright​

As we look to the future, the potential of MACI in reshaping public goods funding is significant. MACI could be used for larger and more diverse funding initiatives, expanding its impact, potentially influencing even governmental approaches to public goods funding. The role of MACI in fostering a transparent, fair, and democratic process for funding public goods is set to be a game-changer. Learn more about MACI by reading through our documentation.

Hey Anon!

In this blog post, we’ll give a high-level, beginner friendly introduction of what Minimal Anti-Collusion Infrastructure (MACI) is, and how it could be used in a real-world context. We’ll take you through the essentials of MACI, making complex concepts accessible regardless of your background in the blockchain space.

What is MACI?​

MACI is a cutting-edge solution that ensures private, reliable voting on the blockchain.

Blockchain Voting Challenges for Beginners​

On-chain voting is a method of casting votes directly on the blockchain, leveraging its decentralized and transparent nature. While this provides us with censorship resistance and guarantees correct execution, the transparency of blockchains can be a double-edged sword. Given all transaction data is public by default, it means everyone can see how anyone voted. This ensures all votes are correctly counted but the visibility could lead to undue influence on voters' decisions, and potentially opens doors for unethical practices like voter bribery. The challenge, therefore, lies in preserving the privacy of each vote while maintaining the core principles of blockchain: transparency, process integrity, and security.

How MACI Offers a Solution​

Minimal Anti-Collusion Infrastructure, or MACI, steps in as an elegant solution to these challenges. Despite operating on-chain, it protects the privacy of voters and votes, thereby significantly reducing the chances of vote manipulation through bribery. How does it achieve this? By employing advanced cryptographic techniques like zero-knowledge proofs (zk-SNARKs), MACI ensures that while the outcome of the vote is public and transparent, individual voting choices remain private. For instance, let's say you vote in an election using MACI, you could claim to everyone that you voted for a particular candidate, but in reality, you might have voted for someone else. There's no way for anyone to verify your claim, making bribery less appealing.

Key Features of MACI​

MACI isn't just a tool; it's a fortress safeguarding the integrity of on-chain voting. Let's break down its key features:

• Collusion Resistance: MACI makes it virtually impossible for voters to be swayed by bribes, as they can't prove how they voted.
• Privacy: Your vote is your secret. Only you know where your support lies, thanks to the encryption technology MACI employs.
• Uncensorability: Every vote counts and cannot be blocked, edited or removed, ensuring a fair voting process.
• Unforgeability: Your vote is tied to your unique digital identity, preventing anyone else from casting a vote in your place.
• Non-repudiation: Once cast, your vote is set in stone. You can change your mind and vote again, but you can't erase your previous vote.
• Correct Execution: The final tally is accurate and tamper-proof, ensuring that the true voice of the voting population is heard.

These features come together to create a voting environment where your voice is heard, loud and clear, without fear of external influence or manipulation.

Technical Overview Simplified​

At its heart, MACI is built on Ethereum, a blockchain platform. This foundation provides a high level of security and trust. The real magic, however, lies in something called zk-SNARKs. Think of zk-SNARKs as a cloak of invisibility for your vote; they hide your voting choices while still guaranteeing the overall vote count to be tallied accurately. This blend of Ethereum's robust framework and the innovative use of zk-SNARKs makes MACI a reliable and secure choice for on-chain voting, ensuring that your vote is both private and counted.

Real-World Applications and Limitations​

Imagine a world where funding for public goods, like community projects or open-source software, is decided through fair and transparent voting. This is where MACI shows its true potential. Quadratic funding is already harnessing MACI's capabilities to enhance user privacy and discourage any form of collusion in funding decisions.

However, like any system, MACI isn't perfect. Its effectiveness hinges on the honesty of the coordinator – the entity or person overseeing the voting process and tallying the results. A dishonest coordinator could pose risks, but thankfully, MACI is designed to minimise even this possibility, maintaining a high level of integrity in the voting process.

Conclusion​

As we've explored, Minimal Anti-Collusion Infrastructure (MACI) stands as a testament to the innovative solutions being developed in the blockchain space, especially for those new to this technology.
