'Orbs was built to bridge the unoccupied gap between the functionality of a public blockchain with the ironclad security of a private one. In a time where people are trusting major companies less than ever before, those enterprises can, at best, ask users to trust them. By empowering those enterprises with the option of operating on a public blockchain safely, Orbs grants them a major competitive edge in the form of digital guarantees to users: No need to trust when users can simply verify.

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.
