There's some big warning signs here.
Firstly, it's a decentralised exchange but the key part of the code won't be open source or explained? That's a fail straight away.
Secondly, I'm highly skeptical they have a bullet proof algorithm in place. It looks to me like they are just hoping to raise a ton of money and figure it all out later on - hardly fair on investors. Either that or it's a carbon copy of one of the existing DEX algorithms that are working out in the wild - e.g. Blocknet.
If you guys can't answer questions on how it works, you are not going to inspire shrewd investors to part with their money. Blocknet for example uses check lock time verify to lock up the funds used for the cross chain trading swaps until the transaction is complete. It has anti-ddos measures in place to prevent orderbook spam. People run the service nodes which handle the trading fees, masternodes cost 5000 Block and collect a proportion of the fees. And so on. How do the validators handle all of this?
Hi most of your questions can be answered if you take a look of the whitepaper which I assume you didn't fully read in details.
Regarding blocknet, it's great there are more decentralized exchanges. I see you are a strong supporter of Blocknet which I assume is also a great project. We prefer it if you go on slack and ask us questions there. You are putting us in a situation that force us to either talk bad about NVO or Blocknet, two different projects, and nothing good could come out of that for both communities. Anyway join us on slack and we will try to answer your question on our side for NVO.
Thanks
