When I was building the very early, the sort of first version of Ethereum in, you know, early 2014. There was definitely iteration there, but it was done in tandem with Vitalik and Jeff. So for sure we were designing to a large degree as we went along. We had EtherPads, a no relation, that allowed us to sort of collaborate in real time on specifications.
We finally sit down with Gavin to go through a bit of what Parity has been working on with Polkadot and Substrate. We talk about Polkadot early history and who was involved and where the idea spawned, up to coding practices and where Substrate became a thing.
