Joseph Delong, senior software engineer at ConsenSys, joins the podcast to discuss a variety of Ethereum topics. Joseph has been heavily involved in Ethereum 2.0 research so we spend most of time on that topic. His research team, TXRX, was recently built out to research eth2 topics such as cross shard transactions, eth1 <> eth2 bridge and much more. He also has a passion for DeFi and he walks us through why and what excites him about it. We wrap up talking about flash loans and the powerful impact they will have on the space.
