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.
Clams were initially distributed to 3,208,032 BTC, LTC and DOGE addresses based on the 12 May 2014 snapshot of these blockchains. Each of these address received 4.60545574 CLAMs. 63,381 addresses have been dug comprising 291,898.39 CLAMs. If all the distributed CLAMs were dug up, the total money supply would be 15,009,015.13. There is no Proof-of-Work stage for Clams and the network is now secured by Proof-of-Stake.
