Ethereum is a smart contract platform that enables developers to build tokens and decentralized applications (dapps). ETH is the native currency for the Ethereum platform and also works as the transaction fees to miners on the Ethereum network. Ethereum is the pioneer for blockchain based smart contracts. Smart contract is essentially a computer code that runs exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. It can facilitate the exchange of money, content, property, shares, or anything of value. When running on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met. Ethereum allows programmers to run complete-turing smart contracts that is capable of any customizations. Rather than giving a set of limited operations, Ethereum allows developers to have complete control over customization of their smart contract, giving developers the power to build unique and innovative applications. Ethereum being the first blockchain based smart contract platform, they have gained much popularity, resulting in new competitors fighting for market share. The competitors includes: Ethereum Classic which is the oldchain of Ethereum, Qtum, EOS, Neo, Icon, Tron and Cardano. Ethereum wallets are fairly simple to set up with multiple popular choices such as myetherwallet, metamask, and Trezor.

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.
