What Is Unobtanium (UNO) ?

Unobtanium (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.

Unobtanium (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.

Unobtanium (UNO) 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.

Now that UNO is merge-mined with Bitcoin it is even more profitable than before. Just use your merge-mined BTC to buy even more UNO!



Unobtanium The charts on this site were generated by a python program that connects to the currency’s daemon and outputs HTML/Javascript. They are not updated live. They charts that end “now” may go out of date if I don’t update them. The height and date of the last block that was scanned is indicated in the info section at the top of the page. Please contact me if you’d like a chart updated.

Logarithmic Scales

Unobtanium It was not uncommon to get data that varies by factors of 1000 over the course of the chart. In order to see anything useful on the chart, it was necessary to use a logarithmic scale on the block generation charts, the minted currency chart, and the transactions chart. Taller bars are exponentially larger than shorter bars. So pay attention to the units on the left and you can hover over bars to get the precise value. Rarely, there are data values between 0 and 1. Due to the mathematics of logs, these show up below the x axis.

Time Periods

Unobtanium Time Periods are calculated from the starting block’s time. For example, if the starting block time is 08:45:00, then hour 1 is from 08:45:00 to 09:44:59 and hour 2 is from 09:45:00 to 10:44:59. Right now, you can’t see the start and end time of a time period on the chart but you can see it in the “Raw Period Data” which is linked to at the top of the page.

Starting Block

Unobtanium Sometimes there is a large gap in time between the genesis block and the first block. This would lead the “first 96 hours” chart to be empty. In those cases, I’ve changed the starting block so that the chart shows the more interesting part where blocks start to be found. Sometimes, the genesis block is reused from a previous currency. In some cases, this causes an empty gap of over a year. In these cases, I’ve started all charts for that currency from the first block instead of the genesis block. Check the “First block processed” field at the top of the page to see if this is the case for a particular page.


The difficulty indicated for a time-period is the average difficulty over that time period. This means that the indicated difficulty may not correspond to an actual difficulty that occured.

Network Hashrate

Unobtanium Network hashrate is estimated based on the number of blocks found in the time period. This estimate does not include orphaned chains. If difficulty was low and there were many orphans, then the actual hashrate would have be higher than indicated. If no blocks were found, this will show 0 even though there may have been hashing.

Minting Error

Unobtanium Sometimes fees are double counted as new mint. This results in a small overestimate of the total supply. This affects smallchange, nibble, luckycoin, americancoin, phenixcoin, digitalcoin, stablecoin, since the block reward is being calculated from the coinbase transaction for those currencies and it’s difficult to remove the fees.

  • Make it easier to compare coins.
  • Handle proof-of-stake better. Show what percentage of blocks are proof of stake. Calculate network hashrate from proof-of-work blocks only. (Done!)
  • Investigate how to avoid counting fees as new mint in certain currencies.
  • Add a YAC N chart. (Done!)
  • Make log scale optional.
  • Account for demurrage in Freicoin.
