I can't find any information on “node”, can you provide a link?.

I will have to research Navajo more in depth to make an informed opinion about it.

How is “Gulden” innovative?. It doesn't seem innovative in the least, only more pollution to the scenario of cryptocurrencies already chock-full of coins that add absolutely nothing. Please correct me if I'm wrong. (No, writing software from scratch that does the same that existing software is not innovation, it is called reinventing the wheel).
