What is Quadratic Funding? How does it work?

Quadratic Voting is a voting scheme introduced and often discussed in the Radical Markets community. It is often considered an innovative improvement of the traditional 1-person-1-vote or 1-dollar-1-vote voting schemes.

As the number of voting contributors for a BUIDL project increases, this BUIDL will receive a bigger matching prize from the community funding prize pool. And Individual contributors can vote for their preferred projects to push them ahead in the funding round. The votes cost MATIC, which is directly donated to the respective projects after the round.

So to be brief, what a BUIDL team can earn from a community funding grant includes:

  • MATIC from the voters used to vote for a particular project;

  • Respective matching prize from the quadratic funding prize pool offered by the grant organizer.

Frequently Asked Question

0. What if I encounter problems during the voting process?

DoraHacks.io provides voting support on Discord, join us here or via Telegram, join us here.

1. Why can’t I vote?

Invalid voting may occur for multiple reasons, please ensure that you:

  • Own a sufficient amount of MATIC (for voting and a gas fee) in your wallet.

  • Connected to DoraHacks.io: you should be notified with a pop-up page on your wallet that asks for authorization to connect with DoraHacks. Once you authorized the action, your account number should appear in the voting interface.

If the problem still can’t be resolved, please contact us on Discord discord.gg/RFXypqtXA9.

2. Can I see my voting history?

Click [Avatar] -> [Profile] -> [Grant Contribution] and check your voting history. And builders are able to view your address at the end of the hackathon.

You are also able to view your voting history via block explorer. In this case, you can verify via https://polygonscan.com/

3. Can I use bots to mass vote for some project?

Absolutely don’t do this. Botting and other ways of cheating will be detected by our anti-Sybil attack mechanism, which is why a grace period (3-5 days) is being issued for such a purpose. Please keep in mind that botting will NOT grant your supported projects any stance of superiority nor impact the prize pool distribution in your favour.

4. Can the project with more votes get a bigger share of the prize pool?

According to the Quadratic Funding mechanism, popularity is the basis of the distribution of the prize pool. If a project is supported by more VOTERS (rather than votes), it will receive more prizes by the end.

For e.g, a project with 10 votes from 10 voters will be prized more than a project with 10 votes from fewer voters.

5. Who receives the MATIC I paid?

The votes (or what we call “donations”) will go directly to the projects.

Risk Notifications

Please note that the generated smart contracts from DoraHacks will arrange and transfer the donated fund, conduct quadratic funding algorithms, and distribute contribution funds to the projects of which the voting results in favour. The website cannot guarantee the authenticity, legality and validity of the project, though admins will contact the projects to verify the validity with their best effort. Be aware of the risks and vote rationally. ETH VIETNAM or DoraHacks aren’t responsible for any adverse consequences.

If you have any questions, please contact us on Discord. We would like to hear more from you and let’s keep in touch!
