Gitcoin Grants is an experiment where people can fund their open source projects for public benefit with QF (Quadratic Funding) matching contributions from Gitcoin’s QF Fund sponsored by donors in the Ethereum ecosystem.

Gitcoin, with the support of the Ethereum Foundation and other matching partners — to run at least quarterly rounds in 2020, with a planned 4 QF rounds. The hope is the regularly scheduled rounds will help grantees use these funds not only as additional donations, but as a strong source of funding for their operations in the Ethereum community. A rough schedule for the rest of the year is below.

  • Q2 Match: March 16th — March 30th
  • Q3 Match: June 15th — June 29th
  • Q4 Match: September 14th — September 28th

What is the scope of Gitcoin Grants?

Gitcoin Grants is focused on public goods.

  • Open Source Software
  • Journalism
  • Public Health

are all examples of public goods. To learn more about public goods checkout

Why should I contribute?

By making an individual donation, you can have a huge impact on a public good.

Contributions of 1 DAI can sometimes mean up to 400 DAI in matching.

Your contributions will be met by matching funding, widening the reach of your donation. If 10 persons contribute by 1DAI (= 1 USD) the QF matching will be higher than if only 1 person is contributing by 10DAI or 2 persons by 5DAI.

TLDR - Your contribution is your vote, and it's more valuable than you think. Your money is having a real impact on Gitcoin Grants.

I've posted a grant, how do I maximize my contributions?

Try to get contributions from the broadest possible audience. In the past, grants that have had 100s of contributors in one round have generated over $10k in funding.

Whats Quadratic Funding?

The QF mechanism is a concrete proposal for turning your small donations into something much larger. It requires a simple formula to achieve this goal.

Crowdfund individual donations towards open source projects (try to have the maximum of contributors, it's the number of participants that counts not the amount of contribution) . 2- A match from governments, grant programs, or private philanthropists ( offered by sponsors/donors for the grant's round fund).

Why is it powerful?

The QF Mechanism measures the breadth of contributors, not the depth of contributions - which is a very democratic funding model. QF pushes power to the edges of the network. Economist Glen Weyl has called QF the 'optimal way to fund public goods that a broad base of population cares about.

I see a grant that is not a public good on the platform, what do I do?

You can use the 'flag' feature to report that grant to our open dispute bot -

From there, if the community feels strongly that this grant is not a public good, Gitcoin may ask the Grant owner to update their grant or remove the grant from the matching pool.

We hope to decentralize this process in the future.

I see a grant that I dont like, what do I do?

If it is in the media round, you can use our new negative voting feature to cast a vote against this grant.

Here are the attributes of both funding types:

Positive - I want to support this Grant. - Grant Contribution on Gitcoin's site will be Public. - Contribution will go to Grantee. - Matching Funds will go to Grantee.

Negative - I want to inhibit this Grant. - Grant Contribution on Gitcoin's site will be Private. - Contribution will go to Matching Pool. - Matching Funds will be deducted from Grantee.

Why isnt the match amount updating?

The QF formula is quite elegant, but its also a bit performance intensive. We will be updating the match estimates ~ every 5 minutes during this round.

How do you prevent sybill attacks?

  1. We use aged github accounts, SMS verification, a few other undisclosed vectors, and (soon) BrightID/Idena Network/ other DID solutions, as an identity solution for Gitcoin Grant contributions.
  2. In addition to Github's native anti-sybil technology, we programmatically check these accounts for signs of sybill attacks. Each contribution is assigned a trust score according to the likelihood that its part of a sybil attack. Right now we dont take any action against sybil attacks (other than the most egregious cases), but we are quietly collecting data to use in the future.
  3. We use Vitalik Buterin's pairwise bonding formula to dampen sybill attacks =>

Are there any rules I need to follow?

Any contribution that can be converted to USDT will be matched during an active match rounds. It will be matched as from a new unique contributor proivded

  1. it is from a new identity that has not contributed before.
  2. Identity requirements continuet to evolve, but for Round 5 a unique identity = a github account that is older than the CLR round.
  3. Identeity requirements are subject to the pretense that a contribution is not a sybil attack or collusion.

We define collusion per the CLR Paper ( ) as

" The central vulnerabilities of LR, as with other mechanisms designed based on the assumption of unilateral optimization, ared collusion and fraud. Collusion takes place when multiple agents act in their mutual interest to the detriment of other participants. Fraud takes place when a single citizen misrepresents herself as many. "

We define a sybil attack ( ) per

" In a Sybil attack, the attacker subverts the reputation system of a network service by creating a large number of pseudonymous identities and uses them to gain a disproportionately large influence. It is named after the subject of the book Sybil, a case study of a woman diagnosed with dissociative identity disorder. "
