I am writing an introducing paper to cryptocurrency. I have a doubt in my mind.
"What are the basic features of 2nd gen cryptocoins compared to Bitcoin?"
or in another words:
"What are the necessary ingredients of 2nd gen crytpocoin? What make them be 2nd-gen rather than 1st-gen?"
In your mind, how many 2nd gen coins there are so far? Which ones?
Some people call coins like Mastercoin that is built ontop of the a bitcoin protocol second generation but personally I think a coin needs to have a completely new code to be true 'second generation'.
There are actually very few in my definition out in the wild though there are a bunch that are but are so much related to NXT I question how much they are new or just a re jig of the NXT code.
So new code that I know of released are:
NXT
Ripple
Qora
Exocoin?
yet to be released:
Node? Possibly just a recode of NXT.
NEM seems like a re jig of NXT, the wallet looks just like NXT but I don't really know. They claim new code.
Emunie Not sure it's still going to exist
Etherurm Corporate sponsored scam, but many will disagree with me.
Syscoin?
Crypti I'm convinced is a scam.
I'll update this list if people show it's a genuine new code.
