Lefteris Karapetsas(@LefterisJP):It's hard to believe it's already been 11 years. On July 30 2015 we launched Ethereum from a small scrappy office in Berlin's Kreuzberg. So much has changed since then. Ethereum has undergone so many transformations yet one thing stays the same. Ethereum is the world computer.
