In what amounted to one of the most far-reaching and interesting conversations at TC Sessions in Zug, Ethereum masterminds Vitalik Buterin, Justin Drake, and Karl Floersch spoke openly – and often candidly – about a bright future for Ethereum scaling and, more interestingly, their way to build teams that work.

“There’s definitely changes that we could have made into the protocol,” said Buterin when asked whether or not he would have changed anything if he could start Ethereum again. But, he said, “there are ways in which that the problem is fundamentally hard.” In other words, growth was the only option.
