Auroracoin is a decentralised, peer-to-peer, and secure cryptocurrency released as an alternative to the Icelandic Króna to bypass governmental restrictions associated with the national fiat currency. It was launched with the aim of becoming the ‘official’ cryptocurrency of Iceland. AUR was a pioneer in the area of country-specific cryptocurrencies. AUR was launched on the 25th of January, 2014, by an anonymous developer who went by the pseudonym of Baldur Friggjar Óðinsson. It was originally based on Litecoin, using the Scrypt algorithm with a Proof of Work mechanism, but was later updated to use a multi-algorithm architecture in 2016, forked from DigiByte. Auroracoin uses the PoW consensus mechanism, which utilises device hashing power to solve a complex mathematical problem in order to authenticate a transaction proposed to be stored in the blockchain. The difficulty of solving the problem ensures that authenticating forged transactions is very difficult unless the attacker owns an impractically large chunk of the network’s total hashing power. AUR is one of the only cryptocurrencies to use a combination of five different hashing algorithms, namely Grøstl, Qubit, scrypt, SHA-256, and Skein. While initially very popular, Auroracoin has seen little to no activity for a while, with poor marketing, and frequent dev team changes. Reasons for little growth have been various, from slow adoption in Iceland, to developers leaving and joining the project midway. However, it is expected to not go lower than the recent low, and might see a rise as AUR plans to launch a more aggressive marketing campaign in Iceland to promote the coin among the masses. Unlike most other altcoins, Auroracoin has made extensive changes to the original codebase. It has introduced security measures such as Automatic checkpointing, and protecting against known flaws present in the BTC blockchain, such as 51% block replacement attacks.

By composing high-quality contents, it can attract other users to join in and form their own 'K Sites'. Users having joined in can read the contents of the 'circle' or post their own content in the 'circle'. On the other hand, users can also set a certain content for paid reading, the more people who read, the greater the income. Users can also reward the content to encourage the author to continue to compose more and better content. KAN will be used to pay for the platform services of BITKAN. If a user keeps sufficient amount of KAN will enjoy a certain percentage discount for service fees, and service fees will be deducted from KAN. The main project team comes from BITKAN, which currently provides price monitoring, news and information, mining monitoring, wallet and other services for cryptocurrencies. Users can store cryptocurrencies simply, conveniently and safely through the BITKAN app. At the same time, they can check the market price of cryptocurrencies of major exchanges in real time, get timely and fresh industry information at home and abroad, and set up price reminders by BITKAN app. And it has real-time mining monitoring, which allows you to master the running condition of the mining machine whenever and wherever possible. The token is called 'KAN'. A strict limit of 10 billion KAN will be issued, and will never be increased. KAN will be issued according to the Ethereum ERC 20 standard. KAN's profit comes mainly from the payment fees, exchange fees and membership service fees from the BITKAN platform. BITKAN is already online. The team is currently developing the 'K Site' feature which is a decentralized crytocurrency-concentrated & content payment community. KAN will be online as the same time as the 'K Site' feature, which is scheduled in May 2018.
