MazaCoin

MazaCoin is a digital currency (of the Bitcoin vein) intended to be the "national currency" of the Traditional Lakota Nation of Native Americans. (It's not entirely clear whether the officialdom of this Native Nation actually endorses it.) It uses SHA-256 cryptography for its Proof-Of-Work used in coin mining, claiming to be the first such currency to use this.
