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.

WARNING: The information on this website pertains to the original Unobtanium cryptocurrency launched by Blazr2 in 2013 on its own blockchain. Beware of immitators including a UNO token on Tezos chain, or Uno-re, who misappropriated the UNO symbol.

In its heyday, UNO was ranked a top 50 cryptocurrency on CoinMarketCap. It had a vibrant community that collected and donated UNO to people doing good in the world. Developers updated UNO with new features. You could spent UNO at thousands of shops through Coinpayments, collectible UNO silver bars were issued, and a prominent global commodities trader exchanged UNO for gold. As time went on, the community dispersed into the other thousands of cryptocurrency projects. A hardcore group of volunteers still monitors the Unobtanium blockchain and attempts to obtain assistance with any issues that are detected. Unobtanium has been running smoothly now for more than a decade. Although UNO's blockchain is powerful, its utility functions have been ursurped by newer crypto projects. However, UNO's longevity, history, stability, and the tenaciousness of its hardest core community members has surfaced UNO as an exceptionally collectible crypto curio and a great example of the 2013 explosion of crypto projects.

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.

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.
