The chapter explores the challenges and potential solutions regarding data limitations in Bitcoin rollups compared to Ethereum rollups, touching on topics like data availability, inscriptions, and security models of sequencers and bridge operators. It discusses the differences between bridges and rollups in both ecosystems, as well as strategies such as atomic swaps and credit-based systems to mitigate risks of potential misbehavior by sequencers.
Summary
In this week’s episode, Anna and Tarun chat with Sims Gautam and Liam Eagen from Alpen Labs. They dive into the world of Bitcoin L2s and focus on how ZK can be used to incorporate strong connections between Bitcoin and new execution environments. The group then explores BitVM, covenants, the distinction between the Bridge Operators and sequencers in this model and how this differs from how these actors work in Eth L2s. They then dive into SNARKnado, including what is happening under the hood, the ways in which this system offers round-based fraud games mixed with ZK and which agent provides DA and more.
