Bitcoin is the first digital currency based on blockchain. It solved the double-spending problem and enabled peer-to-peer transactions on a large scale. Bitcoin was designed to work as a trustless digital currency that would function without government oversight or a central bank.
Bitcoin was developed by Satoshi Nakamoto, whose identity has never been confirmed and has become the subject of great intrigue. Bitcoin builds upon on other cryptographic and digital currency projects that came before it, but its use of blockchain made it more viable. Nakamoto originally released his white paper and open-source software on a cryptography forum. He mined the first block of the Bitcoin chain, called the genesis block in January 2009.
Bitcoins are created as a reward for a process known as mining. One of the core innovations of Bitcoin, is its consensus algorithm, which creates an incentive system that rewards miners for confirming transactions.
Hal Finney, who developed the first reusable proof-of-work system (RPOW), several years before, was the first Bitcoin adopter and received the first bitcoin transaction ever recorded on its blockchain.

Qtum has been described as a hybrid between Ethereum and Bitcoin. Qtum is a smart contracts platform that places a strong focus on value transfers as well as decentralized apps. Qtum enables users to create smart contracts on the platform and conduct cryptocurrency transactions.
Qtum has a Proof-of-Stake (PoS) consensus algorithm. Several decentralized apps are already using the platform.

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.
