Hi, I am just trying our BItshares, I downloaded the client on bitshares.org and am looking at the integrated exchange feature. Is this just connecting to Openledger.info on the backend? From my understanding Openledger is a counterparty like any old exchange, the assets they issues like OPEN.BTC have no proof of reserves or anything you just trust they have the equivalent amount of OPEN.BTC to support trades, is this correct? The bitshares website talks alot about the DEX so does it exist on the client I downloaded and when I place trades I am trading with others using the client or how does it work? Thanks!
