How to apply?

Detailed Application Guide: https://hidorahacks.medium.com/polygon-grants-hackathon-application-guide-1d5c07817d9d

  1. Log in to hackerlink.io and click on Grant — Polygon Grant to apply (new users please register first). Please make sure you have at least 0.01 MATIC as gas fee. For gas fee support, please find hackerlink (Telegram: @hackerlinkofficial).
  2. Join the Polygon Grant telegram group chat to get the latest information about the event. Developers without projects can also team up in the group and turn ideas into projects together! Link: https://t.me/polygonhackathon
  3. In order to prevent fake projects from participating in the prize pool, please contact hackerlink (Telegram: @hackerlinkofficial) to verify your project.
  4. During the Hackathon, we will conduct multiple rounds of project demos, so the earlier the project is submitted, the more attention it will receive. This will surely increase exposure and attract more votes and funding opportunities.
  5. At the end of the Grant Round, before announcing the results, a 72-hour Grace Period will be held to prevent a Sybil-attack. During the Grace Period, each project will be required to contact HackerLink to confirm the authenticity of the project, and after the Grace Period, the project will be able to take out the community donations and the prize pool to match the prize.

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 = (number of votes)².

Individual community contributors can vote for their preferred projects to push them ahead in the funding round. The votes cost MATICs, which are directly donated to the respective projects after the round.

With a quadratic funding algorithm, the cost of each vote to a single project from a single contributor will increase, this encourages community contributors to donate to more projects.

Quadratic Funding was later introduced to the blockchain community by the Gitcoin team by Gitcoin quadratic funding grants. Community members can donate cryptos to new projects to appreciate their effort in building public goods for a specific community. In previous Gitcoin Grants, community members donate ETH to the Ethereum ecosystem projects as community Grants to help them continuously get funded.

To know more about quadratic voting, you can check the Quadratic Funding algorithm by Vitalik Buterin.

The prize pool and allocation

Each vote of the voter directly affects the prize distribution.

The Grant prize pool consists of two parts:

A. Community Contribution

Sky’s the limit. Community members will choose Hacker projects they are interested in to vote, and the MATIC spent on this part of the vote will be directly allocated to the voted project team after the hackathon.

B. $50K Quadratic Voting Matching Prize Pool

The initial prize pool will be allocated to each project according to its popularity.

C. $50K Judges’ Pick Prize Pool

In other words, the final prizes received by the project = community contribution + a share of the quadratic voting matching prize pool + Judges’ Pick Prize
