What about making a community peer to peer marketplace for goods and services that trades directly on blockchain without the need for an escrow service?
The problem
The currently available peer to peer marketplaces are just a centralized list of items for sale that accept crypto for payment. These need to use an escrow service that make the seller wait for a long period of time before receiving the payment for the item they sold.
I don't think this is an issue at all, escrow guaranteed that the buyer will get correctly the stuff or the description the buyer posted in the marketplace its an assurance that the seller will be satisfied and he can reject the product or service if it fails to his expectation and the seller will try to be as transparent and true to what he is offering because of the possibility of rejection of the seller.
The solution
Using a full blockchain proof of reserves to verify the marketplaces reserves as well as obligations in real-time. This will reduce marketplace friction by allowing sellers to receive instant payment for their sold items and also allow both buyers and sellers to be confident that the marketplace is fully solvent at all times.
It only guarantees reserves how about the condition of the product you cannot do that if it only guarantees supply there may be testimonials but we cannot guarantee that those testimonials are not fake, I like the present setup of doing escrow its safe and its a buyer and seller protection
