Hi there.
Didn't find any topic about digital currencies for Merchants. The idea is simple - who are developing such kind of currencies for merchants needs. I'm not a developer but looks like it must have POS integration SDK and be fast enough to pay for cup of coffee in a second. Of course free or low fees prefered, merchants will choose them. What do you think what other features it should have?
Currently i know only few:
Pundi X
Nano
REBL is making a plug n play blockchain infrastructure which could be utilized by merchants and businesses according to there specific needs. They can make business required centralized as well as decentralized blockchain as in accordance to the business needs whereas eventually the token metrics will still point towards the decentralized REBL currency.
