I was thinking of a similar thing. But maybe people logging in 'pledging' interest in sat amounts to projects in their completion. Basically an honour system of paying. Unofficial bounty. Wouldn't have to worry about funds being held somewhere. ¯\_(ツ)_/¯
Like eg
- phpBB forum client
🌟Peter pledges to donate 4k
🌟Sally pledges to donate 20k
🌟Jack pledges to donate 20k
This way even if people can only donate tiny amounts, if interest grows and more and more people pledge it could total quite significant amounts until it becomes tempting to a dev.
