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.

Episode 312: ZKP2P with Brian & Richard

In this week’s episode, Anna and Tarun interview Brian Weickmann & Richard Liang from the ZKP2P project. They cover the opportunities and challenges of building ZK applications with the current tools available, as well as revisit the topic of ZK Email and explore how this lies at the heart of the current version of ZKP2P. They also discuss the goals of ZKP2P, what’s happening under the hood, the types of experiments and initiatives the project is running, how a user can already use the existing product and the opportunities systems like ZKP2P open up.

Episode 311: The Launch of Celestia and Beyond

In this week’s episode, Anna and Guillermo chat with Yaz Khoury and Ismail Khoffi from Celestia. They share how the team prepared for the launch of the Celestia mainnet and what has been happening at Celestia since. They revisit the topic of DA (Data Availability) and explore how rollups and dApp developers can already use the Celestia DA layer. The group discusses Blobstream, which brings the benefits of Celestia to Ethereum and helps to scale the network, as well as community building, the modular thesis and much more.

Episode 310: Algorithmic Game Theory & PoS Tokenomics with Noam Nisan

In this week’s episode, Anna and Tarun chat with Noam Nisan, Professor at the Hebrew University of Jerusalem, Principle Researcher at StarkWare Industries and one of the pioneers in the field of Algorithmic Game Theory. They cover his extensive research and academic background, starting with his work on complexity theory as well as Algorithmic Game Theory and his current work on blockchains and Tokenomics at StarkWare.

They discuss his recent blog post; Simple Tokenomics for a Proof-of-Stake Utility Token, comparing the measurable Tokenomic outcomes of different live PoS systems and explore how Noam aimed to better communicate best practices for those designing these systems, plus much more.
