The Grothendieck Team

Hi everyone, it's my pleasure to officially announce the new team known as The Grothendieck Team! The team has been named after Alexander Grothendieck, a German-born French mathematician who became a leading figure in the creation of modern algebraic geometry. They have been committed to Ethereum Classic by IOHK in order to build a Scala client for ETC based on IOHK's
