Tether (USDT) is a cryptocurrency with a value meant to mirror the value of the U.S. dollar. The idea was to create a stable cryptocurrency that can be used like digital dollars. Coins that serve this purpose of being a stable dollar substitute are called “stable coins.” Tether is the most popular stable coin and even acts as a dollar replacement on many popular exchanges! According to their site, Tether converts cash into digital currency, to anchor or “tether” the value of the coin to the price of national currencies like the US dollar, the Euro, and the Yen. Like other cryptos it uses blockchain. Unlike other cryptos, it is [according to the official Tether site] “100% backed by USD” (USD is held in reserve). The primary use of Tether is that it offers some stability to the otherwise volatile crypto space and offers liquidity to exchanges who can’t deal in dollars and with banks (for example to the sometimes controversial but leading exchange Bitfinex). The digital coins are issued by a company called Tether Limited that is governed by the laws of the British Virgin Islands, according to the legal part of its website. It is incorporated in Hong Kong. It has emerged that Jan Ludovicus van der Velde is the CEO of cryptocurrency exchange Bitfinex, which has been accused of being involved in the price manipulation of bitcoin, as well as tether. Many people trading on exchanges, including Bitfinex, will use tether to buy other cryptocurrencies like bitcoin. Tether Limited argues that using this method to buy virtual currencies allows users to move fiat in and out of an exchange more quickly and cheaply. Also, exchanges typically have rocky relationships with banks, and using Tether is a way to circumvent that. USDT is fairly simple to use. Once on exchanges like Poloniex or Bittrex, it can be used to purchase Bitcoin and other cryptocurrencies. It can be easily transferred from an exchange to any Omni Layer enabled wallet. Tether has no transaction fees, although external wallets and exchanges may charge one. In order to convert USDT to USD and vise versa through the Tether.to Platform, users must pay a small fee. Buying and selling Tether for Bitcoin can be done through a variety of exchanges like the ones mentioned previously or through the Tether.to platform, which also allows the conversion between USD to and from your bank account.
iExec is an open-source, decentralized cloud computing platform, running on Ethereum blockchain. iExec allows decentralized applications (dApps) an on-demand access to computing resources and technologies on iExec cloud. iExec has built a blockchain network where dApps can take advantage of cost effective and high-performance resources such as servers, databases, SaaS applications, web hosting and computer farms. iExec’s native cryptocurrency — The RLC token is the primary asset used to access services in iExec infrastructure. RLC is short for “Run on Lots of Computers.” iExec is headquartered at Lyon, France. It was founded by Gilles Fedak and Haiwu He, both are serving as Chief Executive Officer and Head of Asian-Pacific Region of iExec, respectively. Oleg Lodygensky is the Chief Technical Officer. Gilles Fedak received his PhD from the University of Paris Sud in 2003, and has been working as INRIA (Inventeurs du Monde Numerique) research scientist at ENS in Lyon, France. Similarly, Haiwu completed his M.Sc. and PhD from the University of Sciences and Technologies of Lille, France. On April 19, 2017, iExec launched its token sale and raised more than $12 million in exchange for 86,999,784 RLC. In order to support dApps, smart contracts, and their platforms, iExec takes processing-intensive computations off-chain so as to keep a blockchain’s on-chain functions running smoothly. To do this, iExec makes use of XtremWeb-HEP, an open-sourced Desktop Grid Software. Desktop Grid computing (also known as Volunteer Computing) pools unused computing resources to be used by applications and platforms, and according to iExec’s whitepaper, XtremWeb-HEP “implements all the needed features” to make this possible on a global scale, including “fault-tolerance, multi-applications, multi-users, hybrid public/private infrastructure, deployment of virtual images, data management, security and accountability, and many more.” Essentially, with this software, dApps can utilize any computing resource in the iExec framework to run their programs. In their whitepaper, the iExec team lays out the project’s competitive landscape and explains these competitors in relation to iExec. They’re quick to note that decentralized cloud storage providers like Filecoin, Storj, and Siacoin are not direct competitors, and it’s easy to see why. While iExec could theoretically take a step in this direction as it matures, it’s not a storage platform; it’s a computing platform. This does put it in competition with other decentralized computing protocols like Golem and SONM. Both of these, however, are taking aim at a different animal. Essentially, they’re both building a decentralized supercomputer on blockchain technology, while iExec is targeting dApp development and sustainability. Both look towards a future of a blockchain-powered, decentralized internet, but their functions, while sometimes similar, are more complementary than conflicting.
