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.
ADN Mainnet is a blockchain-based technology designed to secure ICO investments. Going beyond decentralization, we are pioneers of a built-in investor-oriented mechanism to ensure security and transparency to our investors. ADN aims to transcend into the future of blockchain and ICO with continuous development and innovation. Aiming to provide a tangible solution to existing problems within the industry, we developed a blockchain with high-throughput, high scalability, and high availability for Decentralized Applications (DApps) in the ADN ecosystem. Combining the benefits initially proposed by its cryptocurrency predecessors such as Bitcoin, Ethereum, EOS and TRON, the ADN protocol becomes a high-performance blockchain platform. Integrating the Delegated Proof-of-Stake (dPoS) consensus and ADN Virtual Machine (AVM), it primarily focuses on smart contracts, consensus, and ICO wallet.
