This week, Anna and Tarun Chitra chat with Sreeram Kannan, Associate Professor at University of Washington where he runs the UW Blockchain Lab. In this episode, they look at how information theory and blockchain intersect and map the progression of Bitcoin security. They discuss Sreeram’s early work on P2P mobile networks and how this evolved to work on consensus and fair sequencing. Sreeram takes us through his philosophical reasoning of shifting from genomic research to blockchain research and the two major areas in P2P systems that he focuses on: maximum throughput and low latency.

This week Anna chats with Wanseob Lim an Applied ZKP Developer in the Privacy & Scaling Exploration Team at the Ethereum Foundation and one of the authors of the Zkopru protocol. They explore how Zkopru uses optimistic rollups and zero knowledge proofs to create a privacy-focused Layer 2. Wanseob walks us through the transaction process and how the protocol is built to circumvent high gas fees. We also hear a little about what’s to come in the Zkopru ecosystem from merchandising to private exchange of NFTs.

This week, Anna hosts a special 5-part interview with a roundup of perspectives from ZK Hack. First, she chats with puzzle hackers who share what it was like to solve these real-world cryptography bugs and learn complex concepts in real time. They discuss how they got started learning in this space and the resources and tools that helped them. Next, Anna speaks with the puzzle builders on the challenges of designing and building these novel zk puzzles. They discuss the state of the community and how the community could work together to create learning resources to enable its growth. Last but not least, there is a chat with part of the ZK Hack organizing team on what they thought of the event and what’s to come next!

This week, Anna chats with Bobbin Threadbare about his project Miden, a STARK-based roll-up which was recently purchased by Polygon. We recap the differences between STARKs and SNARKs and the increasingly blurred line between these two proving systems. We then map Bobbin’s journey to Miden VM (now Polygon Miden), how it originated from his earlier project Distaff VM and now incorporates the Winterfell prover from his days at Facebook.

This week Anna and Tarun chat with Vasiliy Shapovalov from [Lido](Lido) and Felix Lutsch of Chorus One about liquid staking on the ETH2 Proof of Stake consensus chain. Vasiliy explains Ethereum’s unique PoS validator setup and how liquid staking behaves on this network. They also talk about how liquid staking behaves on other live PoS, the inevitability of liquid staking and how to best design these systems. Lastly, they chat about navigating control and decision making in liquid staking protocols, touching on topics of decentralisation and governance.
