This is my first post here, so hello everyone 
I work on a way to do quadratic funding in the absence of a matching fund. This can be useful when the money from philanthropists is not enough to fund all the projects.
As a new user I have post limits here, but here is the full description of that mechanism: https://forum.effectivealtruism.org/posts/tXavWgk8Xp6Avg8No/quadratic-funding-without-a-matching-pool-1
There’s still a lot of work to be done there, but some simple version could be used already. I’m curious if you have any thoughts on that, and if you’d maybe like to use such a mechanism in your system.
I’d be happy to help in implementing it!
