USDT is a stablecoin (stable-value cryptocurrency) that mirrors the price of the U.S. dollar, issued by a Hong Kong-based company Tether. The token’s peg to the USD is achieved via maintaining a sum of dollars in reserves that is equal to the number of USDT in circulation.
The stated purpose of USDT is to combine the unrestricted nature of cryptocurrencies — which can be sent between users without a trusted third-party intermediary — with the stable value of the US dollar.
Brock Pierce is a well-known entrepreneur who has co-founded a number of high-profile projects in the crypto and entertainment industries. In 2013, he co-founded a venture capital firm Blockchain Capital, which by 2017 had raised over $80 million in funding. In 2014, Pierce became the director of the Bitcoin Foundation, a nonprofit established to help improve and promote Bitcoin. Pierce has also co-founded Block.one, the company behind EOS, one of the largest cryptocurrencies on the market.
Sellars has also worked in several other cryptocurrency companies and organizations, such as Bitfinex, Factom, Synereo and the MaidSafe Foundation.
However, over the years, there have been a number of controversies regarding the validity of Tether’s claims about their USD reserves, at times disrupting USDT’s price, which went down as low as $0.88 at one point in its history. Many have raised concerns about the fact that Tether’s reserves have never been fully audited by an independent third party.
USDT does not have its own blockchain — instead, it operates as a second-layer token on top of other cryptocurrencies’ blockchains: Bitcoin, Ethereum, EOS, Tron, Algorand, Bitcoin Cash and OMG, and is secured by their respective hashing algorithms.
