Nice idea.
While I think its interesting, I find it to be a more complex version of simply funding the team from darknode rewards.
I’d much rather the core team present an annual budget that can be debated and voted on by darknode holders.
A portion of of darknode rewards can be diverted to meet the operating costs as stated in the budget into a multisig thats managed by the core team and representatives of the DAO.
A fundraise would introduce a new set of stakeholders and a more expensive source of funds relative to simply funding the team off revenue - added complexity, at a higher cost, and increased legal exposure.
