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.
Grin coin is a private & lightweight open source project based on the mimblewimble blockchain implementation. MimbleWimble is a lightweight blockchain protocol proposed by anonymous author that goes by the name Tom Elvis Jedusor (inspired by Harry Potter) in July 2016. Since then, the proposal has gained a huge following among Bitcoin and privacy advocates. Unlike bitcoin or ethereum, there are no addresses in Grin. In order to transact using Grin, both wallets must communicate with each other online with the results broadcasted to the network. Another key different is that transaction history (sender, receiver, amount) will not be recorded on the blockchain. Due to the removal of these information from the transaction, the data size remains small and that keeps the blockchain lightweight. New nodes can easily join the network without having to download a large blockchain. Grin coin was launched without an ICO, fundraising, or pre-mine. Developers around the world contribute openly with the goal to ensure the coin distribution remains as fair as possible. There are 2 popular wallets widely available to interact with the Grin network. Grin core wallet: https://www.coingecko.com/buzz/how-to-use-grin-wallet-to-send-receive-grin-coins Wallet713: https://www.coingecko.com/buzz/how-to-use-grin-wallet713-to-send-and-receive-grin-coin-step-by-step-guide The consensus algorithm used by Grin is the Cuckoo Cycle proof-of-work based. There are 2 hashing algorithms involved with Grin. Cuckoo-29 is meant for GPU mining while Cuckoo-31 is meant fo ASIC mining. This is a deliberate design to encourage miners to eventually move into ASIC mining for efficiency while keeping it fair at the beginning of the launch. Grin coin has launched its mainnet on 15th January 2019 and is now available for mining and trading.
