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.
BitTorrent was initially conceived by Bram Cohen, a peer-to-peer protocol for users to transfer files around the world. The BitTorrent Token (BTT), a TRC-10 token is created on top of the TRON blockchain platform as a way to extend the capability of BitTorrent. The token is added to introduce some economics feature on BitTorrent for networking, bandwidth, and storage resources to be shared and tradeed. Some of the other feature that BitTorrent Token (BTT) offers would be BitTorrent Speed. This is whereby BTT tokens can be big in exchange for faster download speed.
