Fetch.AI ('the Project') brings together machine learning ('ML'), artificial intelligence ('AI'), multi-agent systems and decentralized ledger technology to create an economic internet — an environment where digital representatives of the economy's moving parts (such as data, hardware, services, people and infrastructure) can get useful work done through effective introductions and predictions These agents can be thought of as digital entities: life-forms that are able to make decisions on their own behalf as well as on behalf of their stakeholders (individuals, private enterprises and governments for example). Fetch.AI's digital world is exposed to agents via its Open Economic Framework (OEF) and is underpinned by unique smart ledger technology to deliver high performance, low cost transactions. The ledger delivers useful proof-of-work that builds market intelligence and trust over time — growing the value of the network as it is used. Fetch.AI can be neatly interfaced to existing systems with minimal effort, allowing it to take advantage of the old economy whilst building the new: plug existing data in to Fetch.AI and watch markets spontaneously form from the bottom up.
Zcoin (XZC) is a cryptocurrency focused on privacy and decentralization. It is the first coin to implement the Zerocoin protocol that enables financial privacy through the power of zero knowledge proofs with a focus on making privacy easy to use. It is also set to be the first to release MTP an ASIC resistant, anti-botnet proof of work algorithm that remains lightweight to verify to ensure fair distribution of coins and decentralized security. Zcoin is an open source decentralized cryptocurrency that focuses on achieving privacy and anonymity for its users while transacting. To achieve this privacy and anonymity, Zcoin uses zero-knowledge proofs via Zerocoin protocol which is one of the most cited cryptography papers at this point in time. In other words, when you transact using Bitcoin or Ethereum or something similar, your transaction history is always linked to your coins by default which makes you vulnerable. That, because all it takes is one link to your personal information or IP to find out the origin of the coins.However, if you transact using Zcoin’s Zerocoin feature, none of your transaction histories is linked to the actual coins and only the receiver and sender know that you have actually exchanged funds. Zerocoin is a cryptocurrency proposed by Johns Hopkins University professor Matthew D. Green and graduate students Ian Miers and Christina Garman as an extension to the Bitcoin protocol that would add true cryptographic anonymity to Bitcoin transactions. Zerocoin was first implemented into a fully functional cryptocurrency released to the public by Poramin Insom, as Zcoin who is also the lead developer, in September 2016. At the initial stage, Zcoin uses the Lyra2z algorithm for proof of work, then they will transition to a Merkle Tree proof of work algorithm, known as MTP. MTP is a unique memory hard algorithm that aims to solve several problems. Memory hard algorithms help prevent the development of ASICs which lead to centralized mining farms. Memory hard algorithms also prevent the use of botnets infecting computers for mining purposes. If a botnet was using up multiple gigs of memory, you’d be likely to notice something is wrong. “The basic concept is that it should establish the same price/cost for a single computation unit on all platforms meaning that there is no single device that should gain a significant advantage over another for the same price hence promoting egalitarian computing.
