Just chiming in here.  UNB is currently compatible with Blocknet's Block DX... however I'm not sure if you guys are still experiencing extremely long block times.  The last I checked, your difficulty adjustment here is still quite a ways away... is there a plan to fix this in the near future?  The reason why it's a burden to a DX is because you won't be able to retrade funds until they attain at least 1 confirmation... it also opens the door to issues where anyone buying UNB on our 0-conf trading could run into problems too if the mempool is lost as peers here and there go online/offline.  Looking forward to hearing back from you guys here at UNB!
