Is this based on Rubykube software?
The reason I ask is there is very few projects that use ruby for this type of thing and we have seen RubyKube in the past I wondered if this was based on that project?
Also running something like this takes a lot of skill and time, End of the day if people use it your dealing with customer funds and need to be aware of security processes to protect wallets and user data. It's not something to just go out and start an exchange there are a lot of things a user should factor in.
*EDIT*
On further inspection this seems to be a clone of RubyKube's, MicroKube system I would advise anyone looking to use this to compare it to the ORIGINAL source as the author of this topic has failed to tell you this is a clone of RubyKube.
Link to original source :
https://github.com/rubykube/microkubeWe are the guys who did RubyKube

So we call it OpenDAX now

Kinda cooler, don't you think?
But yeah, technical stuff aside - you need a good business logic if you want to run a financial exchange platform.
