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.
Ampleforth is a digital-asset-protocol for smart commodity-money. The smart commodity money with a unique elastic supply protocol. AMPL supply expands and contracts in response to it’s price deviating from a 1 USD target. Deviations result in a supply change of AMPLs once every 24 hours, increasing or decreasing the number of tokens in each holder’s wallet pro-rata. Ampleforth is the only asset in the world with this elastic supply property, and therefore has counter-cyclical trading pressure and is uncorrelated with other digital assets such as Bitcoin.
