In this podcast, hosts Vikram Ramakrishnan and Faizaan Shamsi, partners at the software consultancy QuantLayer, talk to investors and builders of the cryptocurrency arena. We discuss how industry participants think about crypto assets, how they uncover fraud in the market, and which technologies will turn the budding, nascent crypto space into the revolutionary powerhouse early market participants had hoped for.

Dr. Ed Felten is a professor of Computer Science at Princeton, he’s served as Chief Technologist at the FTC and Deputy CTO at the White House. He’s also the cofounder of Offchain Labs, a Princeton-based startup that’s focusing on 2nd layer smart contract solutions to improve scalability. This was one of our favorite conversations to date. We discuss smart contracts and their current problems. We discuss Arbitrum, Offchain Labs’ solution to the smart contract scaling problem which uses a system of validators to provide a guarantee to smart contract participants. Moreover, we discuss at length how their AnyTrust guarantee works, and why only a single validator is needed to maintain a working system. We also go through how an existing dApp can get ported over to Arbitrum. Finally, we talk high level tech themes: How technology and public policy are becoming more and more interconnected, how technology advising will become more and more important over time, and other technologies he’s really optimistic about. It’s a really packed episode. Enjoy.
