I would love to buy this but the anonymity is a big problem for me and a lot of others.

So I propose this:

The team can remain anonymous, but they find an escrow whom they trust and is known to the wider community. That escrow releases funds to them as they hit milestones on the roadmap. There's no reason they'd have to reveal themselves even to the escrow, as long as he is trustworthy.

Any reason this wouldn't work?
