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 MATIC.

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.
