Liberty Dollar is listed under "failed". As far as I've ever heard, it was just a private currency based on gold and silver, not a cryptocurrency or anything similar.
I remember they were planning some sort of digital currency but it seems I've confused it with Liberty Reserve. I first got involved with e-gold and other digital currencies 6-7 years ago and with so many of them coming and going, I guess my memory is a little hazy on the area.
Good catch.
Wasn't it shut down by the F.B.I.? It be instructive to see if something similar can happen to a crypto-currency. Maybe it is not directly relevant, but still useful to keep around in the wiki.
