Thank you
@Stan, the referral program makes sense for the smaller entities here. But it requires that some percentage of UIA trading fees go to the referral program. UIA issuers and referrers do have arguments about this.
In regards to the EBA concept, imo it somehow conflicts with shared order book concept. From 2 or more member exchanges which have similar sizes, you can only get EBAs OR shared order book, not both. Smaller exchanges can adopt EBAs issued by big ones and share their order book though, like USD. Smaller ones can also united together and issue another EBA like EUR (big ones can united together as well).
So in conclusion we can give out two choices to targeted exchanges (which are our potential partners):
1. Adopt EBA's issued by existed partners(or maybe a union of some partners), and get shared order book,
2. Issue their own EBA's and compete with others.
To promote the first one we need liquidity, to promote the second one need user base.
