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. The simplified formula on how quadratic voting functions is:

Cost to the voter = 1+2+3+…+ number of votes USDC

With such a mechanism, community contributors can vote for their favorite projects and emphasize their preferences through multiple votes. Along with the increased contribution each round, of course.

How would this affect project incentives? Popularity, which is embedded in this mechanism and is comprised of the total number of votes driving the top project with the most allocated prize. Plus, the accumulated USDC will go directly to the respective project after each round.

Interested to know more about quadratic funding? You can check the Quadratic Funding Algorithm by Vitalik Buterin, or the Quadratic Funding V2 Protocol by Eric Zhang.

Frequently Asked Question

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

HackerLink provides voter support in Telegram, join us here.

1. Can I see my voting history?

Voting history is unavailable for voters at the moment. But builders are able to view your address at the end of the hackathon.

However, if you would like to verify the validity of your votes, you are able to view your voting history via

2. 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 in any stance of superiority nor impact the prize pool distribution in your favor.

3. 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.

4. Who receives the USDC I paid?

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

5. Why can’t I vote?

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

  • Own a sufficient amount of USDC & SOL (for gas fee) in your wallet.
  • Connected to HackerLink: you should be notified with a pop-up page on your wallet that asks for authorization to connect with HackerLink. Once you authorized the action, your account number should appear in the voting interface.

If the problem still can’t be resolved, please contact Voter Support at Telegram via

Risk Notifications

Please note that the generated smart contracts from HackerLink will arrange and transfer the donated fund, to conduct quadratic funding algorithms, and distribute contribution funds to the projects of which the voting results in favor. 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. Serum, HackerLink or DoraHacks aren’t responsible for any adverse consequences.

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