In 2012, J.R. Willett published a whitepaper which described the possibility of building new cryptocurrencies on top of the Bitcoin blockchain. Willett went on to help implement this idea in the cryptocurrency Mastercoin, which had an associated Mastercoin Foundation (later renamed the Omni Foundation) to promote the use of this new "second layer". The Mastercoin protocol became the technological foundation of the Tether cryptocurrency, and one of the original members of Mastercoin Foundation. Brock Pierce, became a co-founder of Tether. and Tether founder, Craig Sellars, became the CTO of the Mastercoin Foundation.
The precursor to Tether, originally named "Realcoin", was announced in July 2014 by co-founders Brock Pierce, Reeve Collins, and Craig Sellars as a Santa Monica based startup. The first tokens were issued on 6 October 2014, on the Bitcoin blockchain. This was done by using the Omni Layer Protocol. On 20 November 2014, Tether CEO Reeve Collins announced the project was being renamed to "Tether".
