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.
'Cryptoindex.com 100 (CIX100) is a digital expression of the top coins that continuously recalculates itself. The index represents a mathematically computed value of all the coins, included in the structure of the index, which is changing every second along with the movements of their price. It is integrated with the multitude of main cryptocurrency exchanges, tracking of tens of millions of trades and orders per day. The unique aspect of Cryptoindex is that it tracks the entire crypto market, not just the Bitcoin space but taking into account the likes of Ripple and Ethereum and etc. Over 1,800 coins are put through our fixed set of filters, which provides around 500 coins as a rough output. Data is collected from cryptocurrency exchanges, news, social media, such as Twitter, GitHub, and other sources. The collated data is used to extract over 200 factors that create a refined ranking in the index. Then, the factors are fed into the neural network, creating a final rating of coins, with the top 100 coins making up the Cryptoindex 100. Rebalancing of the Cryptoindex 100 happens monthly, when the composition of the index is changed by up to 22% on average. '
