Nostr could play a part.
DAOs are more of a concept tbh than purely a Web3 thing.
Most of them didn’t work etc… in my opinion.
Needs a pool of money (Bitcoin) which I suppose we could hold safely somehow with multi sig - and a place to discuss and vote on funding.
People can even Lightning pay for fundraising via lightning which https://zaplife.lol already has with “zaprisiers”.
Place of discussion and voting I suppose could be done via Nostr so we have an identity attached? 🤷
Just initial first thoughts.
