Quarkcoin is a coin which increases security by using 9 rounds of hashing from 6 different hashing algorithms - blake, bmw, grøstl, JH, keccak, skein. 3 of the hashing rounds apply a random hashing function. This compares with Bitcoin's solitary use of SHA-256 algorithm. There is no pre-mine for this coin. A new block is generated every 30 seconds and 2048 Quark is given out as reward per block at the beginning. This reward halves every 60480 blocks or roughly every 3 weeks. The initial supply of Quark is 247 million and this is expected to be mined in roughly 6 months since launch date. The supply will then continue to increase at an inflationary rate of 0.5% per year. Quarkcoin was launched on 21 July 2013.
'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. '
