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.
PolySwarm in 60 Seconds. Polyswarm is a decentralized threat intelligence market made possible by Ethereum smart contracts and blockchain technology. Polyswarm incentivizes rapid innovation in the $8.5B/yr anti-virus and automated cyber threat intelligence space with precise economic incentives that reward timely and accurate threat intelligence concerning the malintent of files, network traffic and URLs. PolySwarm defines a real-time threat detection ecosystem involving enterprises, consumers, vendors and geographically-diverse security experts. Experts develop and hone competing “micro-engines” that autonomously investigate the latest threats, attempting to outperform their competition. PolySwarm’s “Proof of Work” is threat detection accuracy: the market rewards experts who are best able to defend enterprises and end users. Relative to today’s ad hoc market, PolySwarm will lower the barier to entry, provide broader coverage options, discourage duplicative effort and ensure interoperability among products and threat intelligence feeds. Economically, PolySwarm functions as a skill-required twist on a prediction market2 with thousands of micro-engines (“workers”) investigating the latest in malware evolution at machine speed - no human in the loop. PolySwarm will be developed by Swarm Technologies, Inc. (“Swarm Technologies”) with funding derived from the sale of ERC20-compatible Nectar (“NCT”) utility tokens. As a utility token, PolySwarm economically disincentivizes Nectar speculation by rewarding honest market participation through the collection and distribution of Fees (details on page 6) to valueadding, active participants.
