Blackcoin is a copy of Novacoin, (but BC 1st turned of POW part with solved fork issues without POW Yea once were time bomb attack -was patched)
Novacoin is copy of PPC (but Nova added coin age )
PPC is copy of BTC (but PPC added Pos protocol to POW coin )
generally at creation stage those coin had those features...some tweaks exiting code but they made steps forward with code.
I don't blame XBL or whatever coin but what is for you "no innovation at all." generally is evolution of crypto...
Sooner or later we will get rid of blockchian that will be next crypto gen.
XBL stepped on mine field with zerocoin ( Anoncoin devs are trying implement it hmm 6 months so is not so easy )
Even DRK was working with anon feature for a while... ( 2 years old source code )
XBL wil get anon feature sooner or later but is work not on 2 days of work but months.
