Bitfinex are working on a decentralised exchange called Ethfinex, and Blocknet has held their second series of talks with them to use their tech for the Ethfinex orderbook:

Blocknet is the only truly decentralised exchange platform I know of, doing true atomic crosschain swaps as opposed to colored coins, IOU tokens etc.
The question is, will this cause a pump of Block... Or is this more of a long term thing that will take time to take effect?
