Build an ethereum contract (or verify and use an existing one) that refunds all money received unless a 'goal' is met, like a 'guaranteed money back if useless'

Build an ethereum contract (or verify and use an existing one) that refunds all money received unless a 'goal' is met, like a 'guaranteed money back if useless' GoFundMe. Allow people to submit ideas that you're willing to vet completion for (this gets tricky/arbitration-y, encourage splitting this up into phases/steps rather than a giant lump sum) like an 'only pay if you get it' Kickstarter/Upwork. With a twist: find a way to use all the pending deposits for proof of stake and return most of what is earned to those who have committed to potential projects. Consider making your own transaction fee equal to the ethereum transaction fee for all your transactions. I may spam a couple more as separate comments...
