Unobtanium is a Proof-of-Work (PoW) cryptocurrency that uses the SHA-256 hashing algorithm. It was designed to serve as a commodity and store of wealth that would be less vulnerable to price fluctuations. The coin's supply is limited to counter inflation, and UNO coins were distributed in a manner that would discourage centralization. UNO can be merge-mined with Bitcoin.

FairCoin

FairCoin is based on an innovative blockchain technology, which has been changed in July 2017 from a 'Proof-of-Stake' protocol to a 'Proof-of-Cooperation' (PoC) mechanism. Our currency not only requires less energy and enables faster transactions, but also introduces a certain level of trust and democratic values even on the technical level. Here you find the White Paper and more information about PoC and our FairChains project.

With the support of FairCoop, FairCoin implements fair value exchange on a global level. Our innovative Proof-of-Cooperation (PoC) blockchain mechanism is the unique consensus algorithm developed for FairCoin. It requires much less energy than other blockchains but also enables faster transactions. We are proud that FairCoin now is the the most ecological and resilient cryptocurrency.
