I've just downloaded the latest version three of Particl Desktop. there have been a lot of updates to the software since I last looked at it! In addition to the main market, I hear there are now private/hidden marketplaces within the protocol. does anyone know how to find them?
Curious what items are in the hidden marketplace?

But how is the trust factor of the buyer and seller is measured here? Is it also feedback-based? Because how can you trust the seller that he has the item to sell? Or how can you trust that the buyer will pay? So is the particl platform serves as somewhat escrow here?
