Bismuth, a digital distributed self-regulating database system whose primary application is currency, and its first application is mining. It comes with a set of DAPPs out-of-the-box. Bismuth is not based on the code of BTC or any of its derivates, it is only inspired by some ideas laid down by Satoshi Nakamoto (BitCoin), Sunny King (Peercoin), NXT and ETH developers. Bismuth does not draw any code from other repositories, instead, it reformulates the cryptocurrency code in its own terms to be easily readable, compatible across all platforms, integrated into business solutions with utmost ease and most importantly open for development to a wide public through its simplicity while minimizing the security risk for custom code implementations. Bismuth is a decentralized transaction platform focused on modularity and open source approach. It comes with default decentralized applications and tools out of the box, not only to be used by everyone but also to be hosted by anyone. These applications are supplied as interpretation engines, which prevents blockchain bloat. Inspired by Satoshi’s whitepaper, Bismuth also offers optional hyperblocks as a pruning mechanism, a system which greatly reduces disk space usage and increases execution speed.
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.
