 To overcome this, a number of new matching platforms, such as [GitCoin Grants](https://www.gitcoin.co/), connect sponsors (small donors and grants) using a "plural funding" formula that accounts not just for the total funding received, but also the diversity of its source across individual contributors and connected social groups.  These platforms have become important sources of funding for OSS, channeling in total more than a hundred million of dollars in funding. This has been especially important to Web3 related projects, in Taiwan, and in supporting this book. They are also increasingly being applied to domains (e.g. [environment](https://moda.gov.tw/en/ADI/news/bulletin-board/5451), [local business development](https://medium.com/@katiebrenjohnson/downtown-stimulus-program-review-e89f67e29f4f)) outside OSS.

The one on the right is a corresponding quadratic slider showing that $10 will be matched by $74 and that if the left one was slid all the way to $1000 the match would be $5000. Together this illustrated that due to quadratic matching, lesser donations receive a higher match per dollar.>
