Hash of color descriptor?
! Where is the color descriptor? Is it on the block chain or on some external file somewhere.
Here's an example of color_desc: "obc:b3b2c25ea6366d8506ea338f8e93624af897f284a511864eafe472d283819b41:0:147478"
It identifies a particular color, like URL identifies a page on a web site.
C'mon guys!!! You have to step up your execution!
I do what I can... Why won't you help instead of complaining?
FYI that "Colored coins - BitcoinX" whitepaper is dead.
