This is not a hard fork, it is just a rebranding of the name. Really nothing changed for you as a user, just that you have to look up another three letter code when searching for blackcoin on an exchange.
I havent loaded my wallet for a while, opps. Sounds like no biggy then, any update should swap in ok
Blackcoin joins the big names of cryptocurrency used in the new Secure Email Protocol DIME's specs by Phil Zimmerman (PGP) and Ladar Levison (Lavabit)!
That sounds massive, I remember the PGP guy from way back when he was in trouble with the law. Its good to see Zimmerman involved and active in projects as he is like a father figure to this all in my mind
