Episode 151: John Adler on Optimistic vs ZK Rollup and the data availability problem

In this episode, we chat with John Adler - co-founder of Lazy Ledger (now Celestia) and Fuel Labs. We compare Optimistic Rollups and ZK Rollups as well as discuss how Ethereum, specifically Eth1, could look over the next few years. We also talk about the data availability challenge in blockchains and how Lazy Ledger aims to solve this.
