Unobtanium (UNO) is a decentralised open-source cryptocurrency forked from Bitcoin in 2013. It derives its name from a fictional engineering and scientific term that describes an extremely rare or impossible-to-obtain element. Members of the UNO community often measure the amount of their UNO cryptocurrency holdings in kilograms rather than coins. Unobtanium is a rare, SHA-256 proof-of-work cryptocurrency with the maximum supply of just 250,000 coins. With 0% pre-mining and no replacements for lost unobtaniums, it is considered a "fair-mined" cryptocurrency, with scarcity being its most distinguished feature. Original announcement.
