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.
Sentivate is a revolutionary advancement, not evolutionary, in Internet architecture. Sentivate has a hybrid topology consisting of interconnected centralized & decentralized systems. The network is designed to go beyond the capabilities that any solely centralized or decentralized network could offer. Sentivate has the ability to operate in a decentralized or centralized topology, if the need ever arose, giving it a unique dynamic topology. With Sentivate's data transport protocol, UDSP, all the issues associated with TCP will be a relic of the past. Sentivate is designed to be a realistic and viable replacement for the increasingly slugish Web we have today.
