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.
'Tael is a digital token for safe consumer products. Thanks to its ability to be seamlessly integrated by third parties, it allows for a wide token use-case through interchangeability of the loyalty tokens on the blockchain. Tael’s first use-case is seen in Techrock’s safe consumer products ecosystem. Techrock applies banking-level, tamper-proof NFC smart-labels to consumer goods, pairing them with their digital representations on the blockchain. Consumers ‘touch’ the label with their smartphones to verify a product’s authenticity, discover the product’s journey along the supply chain, and be rewarded for their purchase. Techrock protects products where authenticity matters, such as infant formula, cosmetics, alcohol, and supplements. Tael tokens are used in the loyalty point ecosystem to reward consumers and encourage behavior in the Techrock channel while generating unique data for all companies in the value chain. Tael’s vision is to bring blockchain based payments into the mainstream, across Asia and beyond.'
