How does barterdex differ from Bitshares decentralized exchange or from the DEX being built by BLOCK?
bitshares is a proxy token based DEX, when you trade on it you dont actually trade the coins, just a token that represents the coin. Who guarantees that the token will be able to be traded for the real one? Even if they use automated multisig like our MGW did years ago, it is still nowhere are reliable as atomic swapping the actual coin.
The DEX being built by BLOCK appears to be the closest to what barterDEX is. From what I have seen the ordermatch system is different and they also dont support electrum servers like barterDEX does.
The upcoming dICO will be a first mass usage usecase for a native coin DEX.
