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.
Dragonchain is one of the newly launched cryptocurrencies that is attracting crypto enthusiasts following its relaunch. The coin seems to be leading on the technology front irrespective of its market capitalisation trends, which is why it's also being anticipated to be Ethereum’s competitor. Dragonchain is a hybrid blockchain platform, where sensitive business logic and smart contract functionality is held by the owner. Its cryptocurrency is denoted by the symbol DGRN & has a total supply of 433,494,437 coins. Dragonchain uses serverless smart contracts from its pre-built library. This feature is unique to this cryptocurrency, as it can create smart contracts, with or without cryptocurrencies. Dragonchain was developed by Joe Roets who is its CEO and Chief Architect with a team of 4 core developers. The team is backed by a strong advisory board with Jeff Garzik on board who is established icon in the Bitcoin network. It was developed after exploration of 20 use cases and applications. It was released under the Apache 2 license in October 2016 to integrate real business applications onto a blockchain, protect business data and operations, currency agnosticism and multi-currency support. The launch of Dragonchain Foundation, a non profit corporation, in January’17 maintains the ownership and responsibility of Dragonchain’s open source code. Enterprises can easily design smart contracts in a variety of languages like Python, Node, C# & Java. The contracts can be specific to their business needs to include both private internal and public blockchain interactions. The Currency Smart Contracts help organizations to retrieve and transfer specified currency amounts between wallet addresses and check balances which can be run on schemas like ERC20, ERC223, etc. Dragonchain helps enterprises to leverage their models using blockchain by allowing development and integration before the economic model is known. Monetization can be applied after sufficient real data is available & system is functioning. DragonChain’s platform is establishing a niche in the crypto world with its layered security feature. The 5-layer security model adds great credibility to their overall goal of facilitating business integration into the blockchain. Additionally, DragonChain is seen as a strong rival to Ethereum because of the platform’s ability to scale; an issue that Ethereum has been notorious for. As of January 2018, the DragonChain team is raising funds and finishing development of the platform. Although the exact date is currently unannounced, the DRGN platform is expected to fully launch sometime this year.
