Quarkcoin In concept, Quarkcoin (or Quark) is close to Litecoin. It has faster transaction times than Bitcoin (typically a few minutes versus an hour). Its security algorithms are much more advanced than Bitcoin and this means that normal PCs can be competitive in mining coins. Miners who buy expensive high speed machines for Quarkcoin will have much less of an advantage than those doing the same for Bitcoin.
