Hypercerts are certificates of work and impact that can be assessed by evaluators and funded - before or after the fact. https://hypercerts.xyz/

I start this market at ~50% as to whether most 'impact projects' should issue an hypercert for themselves. This is a more precise question than whether 'impact projects' should be part of an impact market.

(I will feel free to improve this description with more clarity, and I will notice when I do so.)
