The original rare cryptocurrency

UNO is a SHA256 Proof of Work cryptocurrency unique for low inflation, scarcity, a fair launch and distribution. It is one of the oldest cryptocurrencies. Just 250,000 Uno will ever be mined over 30 years. Unobtanium is merged mined with Bitcoin, resulting in a secure high-difficulty blockchain that is 3x faster than Bitcoin.

Uno is rare not only in the number coins issued, but also in it's fair launch and distribution. Uno was not pre-mined. The launch was pre-announced on Bitcointalk and is indisputably fair, with the first 1000 blocks mined at low reward to provide miners time to configure equipment. There is no POS inflation. There was no stealth or ninja launch of Uno. All Uno come to exist through mining.

Watch Introduction »

Years after it's launch, Unobtanium remains a highly collectible cryptotoken that has held its value. Unobtanium is not invulnerable to short term price swings. But check the long term price chart in USD or BTC, and you will find that Unobtanium has an unparalled history of growth and value retention. Long term growth punctuated with short term volatility has made Unobtanium a favorite of savvy investors and traders.

Block Rewards


Unobtanium mining started with a block reward of .001 for the first 2000 blocks to come up to a difficulty target. From block 2001 the block reward was 1 kg per block, halving every 100,000 blocks and finishing with a minimum subsidy of .01 after 15 halvings.

Unobtanium distribution has two stages. Roughly 190,000 units will be distributed during the first 6 block halvings. The remaining 60,000 units are for long-term mining support.
