Ethereum Classic is the name of the cryptocurrency that has been designed to retain the core of the original Ethereum technology , which was created by Vitalik Buterin back in 2013. In February 2015 , the Ethereum Foundation ( Ethereum Classic's official name) was formed and it was made up of developers and business people from Ethereum's past who wanted to help the project to reach its goals. Ethereum Classic aims to take what was done with Ethereum Classic to the next level , and this is reflected in its own name . The Ethereum Classic project has several different variants and they all work together to build an ecosystem that uses the Ethereum blockchain to build applications and services . The developers behind the project have a long history of working on a wide range of blockchain technologies and it 's fair to say that many of their efforts have had an impact on the rest of the cryptocurrency ecosystem and will continue to do so ..
