Hello Josef, and thank you for the encouraging comment Right now PayCoupons is not open source … I'm not excluding that at some point, but right now we don't have a plan for that. Honestly, before that we'll need to have some success with it first and earn some of our investment … .
It is also not hard to make a copycat version. Our network barter algorithm performs ca. 30% better than simple circular barter, but these 30% are not advisable to even utilize because the order network would take a long time to "recover" until a new trade becomes possible after draining all barter liquidity out of it with a network barter trade … . So basically, any copycat version would only have to look at our features and add a normal circular barter algorithm. Much simpler to build a new class of software once you know how, rather than designing it from scratch … in the case of PayCoupons, the feature set had about 10 major changes before it finally settled the way it is now. So let's say, the software design is free and open, the code is not. (Though if any major source of funding appears, I have no issue to make it open source. I love open source and apply it wherever I can, just in this case it's a challenge so far …)
