Singing on stage alongside songwriter Jonathan Mann, ethereum founder Vitalik Buterin ended his keynote at Devcon4 in Prague on Wednesday, with a song that listed “the graveyard of ideas” from the past five years of ethereum research.
An annual ethereum developer conference, Devcon4 is all about ethereum – past, present and future – and Buterin took his time on stage to touch on all those time periods as it relates to the platform’s long awaited switch to a more scalable and ecological paradigm.
