There is nothing that can properly be called "Bitcoin 2.0", yet. Nothing.
...by your definition which reigns supreme over all others? Please tell us when we can call something bitcoin 2.0 according to your definition.
By other peoples definition, colored coins, Mastercoin, Counterparty, et cetera, which are not new coins, but rather extensions of the standard bitcoin protocol to enable new interesting functionality - is Bitcoin 2.0.
But somehow BurtW wants to tell everyone what they can and can't call things. Burt the head arbiter of the dictionary. WTF?
Bitcoin 2.0 is a very interesting new space. It will be quite popular in about 1 more year.
Good idea to add section of btc2.0 to that forum. Can you give some information about btc2.0?
Well, the very beginning of this started with JR Willet's white paper. Maybe you should start there.
