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.
X-CASH is a cryptocurrency based on blockchain technology. The platform aims to become a global intermediary for all kind of payments and reduce transaction costs by 99%. X-CASH is a cryptocurrency built on Monero v7 with the aim to become a standard in digital payment and transaction settlement. We believe privacy is very important when it comes to managing personal finances, but at the same time, banks and institutions need to know the source of the funds for KYC purposes. Therefore, we plan on leaving the users the choice of whether or not they want their transaction to be public. Because we are implementing a worldwide network of dedicated servers, we hope to make the synchronization of the blockchain faster than other cryptocurrencies as well as reducing transaction latency. We believe this network will be a key component in the deployment of the future improvements we plan on adding to the core code.
