As a "regular" blocknet trader I can answer second part of your questions. I am running few unencrypted core wallets on some old notebook with linux. It has only wallets and blockDX installed. With good SSD the performance is acceptable. You need to have all wallets synced on same machine with blocknet (a lot of time, if you start from beginning) and configure blockDX with all that wallets. Especially if you add new, you need to restart every wallet, that is annoying. But! It is working. Devs promising, that you do not need to install core wallets if you use some services (service nodes??), but I do not know any or how to connect to them. Most important for me IT IS FUCKING WORKING! No more KYC, AML, exchange SCAM or trust to someone else. I just hope, blocknet does not have any backdoors or critical bugs

Thank you for the great deal of very useful information, it's especially comforting to know that the time and effort required to do the setup pays off and this was my main concern. I'm really happy to hear it's working, and can't wait to get my own setup going soon!
Why bother man. People may not recognize the value of their time if they bother setting up wallets and connecting to a dead chain. How many years have it been since XC went belly up? Now how many years have it been since their 3000BTC ICO after which it all came to a halt? Its been 5 years. And these maddish fan boys from 5 years ago are still tottering around, fueling this discussion.
Well, it's gonna be way more user friendly once the Litewallet is out, which will leverage the snode network instead of requiring you to have a copy of the full blockchain yourself like it's required in the current form.
The snode in the DX is basically acting like an extra pair of eyes on things. The snode has no control over the trades or funds themselves, but tracks the utxos used in trades so that they can't be duplicated elsewhere - subsequently limiting orderbook bloat. The orderbook itself, however, is maintained and shared by the actual peers/traders themselves.
The snode also provides disaster recovery: For example let's say a trade fails and you need to reclaim your funds from the p2sh (pay to script hash) - the snode can broadcast the sendrawtransaction to the network for you if you happen to go offline.
