I can't find details anywhere. Would be interesting to see just how similar they are.
Also, I think that digital currencies won't catch on for many years to come. Something like 40% of Americans have heard of it. A big majority of Americans don't know what it is, and even if they do, have literally zero trust or desire to use it.
I get the first adopter enthusiasm. I remember getting Mandrake Linux and being like "This is gonna drive out all the shitty OSs, wait till people see all the benefits, etc." Fifteen years later, after Linux and BSD has been stolen, modified and commodified into AppleOS and Android, still nothing.
Most people will never adopt a currency that cannot be refunded and has no regulation whatsoever.
If it ever is adopted mainstream, it'll be decades from now, IMO.
