In this week's episode, we chat with Brian Gu, a student at MIT and creator of the Dark Forest game. We chat about education in the space, blockchain based games and how Dark Forest was inspired. We then dig into how this game creates an incomplete information game space by using zkSNARKs to create a “cryptographic fog of war” and more!

blockchain, crypto, crypto finance, cryptoeconomics, decentralised finance, defi, proof-of-stake, stalking rewards, validators
In this week’s episode, Anna and guest-host / frequent guest Tarun catch up with Alex Evans, researcher at Placeholder Capital. They dive into the latest in DeFi, a topic that we don't cover too often, but is hard to ignore. Specifically they discuss the emergence of liquidity farming, the difference between the zero knowledge Research space and the DeFi space, some emerging concepts like AMM and staking derivatives, and cover a recent report Tarun and Alex published together on the impact of staking derivatives on the security of PoS systems.

This week, we catch up with Benedikt Bunz and Ben Fisch, PhD students at Stanford, once again. In this episode, we dive deeper into Findora, a project that was co-founded by Ben (who is also the CTO) and where Benedikt works as the Head of Research. We look at what the Findora project is, discuss the "selective disclosure" concept at the heart of their constructions, explore the balance between transparency and privacy and describe what problems Findora aims to solve.

In this episode, we chat with Molly Mackinlay, Project Lead for the InterPlanetary File System (IPFS) at Protocol Labs. We talk about her journey to Protocol Labs, as well as take a deeper view into IPFS, LibP2P, Bitswap, Testground, the use cases and projects working with these tools, and the specific upgrades they have made with the recent 0.5 IPFS release. We also chat about the path to decentralisation and the importance of building bridges to the Web2 world.

In this week's episode, Anna catches up with Kenny Paterson, Professor of Computer Science and Lead of Applied Cryptography Group at ETH Zurich. The goal of the episode is to take a deeper look at DP-3T and privacy preserving contact tracing research in Europe generally. They cover his work at ETH Zurich, discuss how the DP-3T project came to be, look at risks facing contact tracing protocols generally, and discuss why putting privacy and decentralisation at the heart of these types of protocol is so important.

In this week's episode, we go deep on Consensus Algorithms and HotStuff with Ittai Abraham from VMware Research. We chat about the evolution of consensus algorithms, BFT, and how these early ideas have become the backbone of blockchain tech. We cover PBFT, Tendermint and Ittai's research into SBFT, HotStuff, and the improvements he has been working on since HotStuffs incorporation into Facebook's Libra protocol.

cryptography, fhe, homomorphic encryption, ibm research, mpc, technology, zero knowledge
In this episode, we chat with Flavio Bergamaschi from IBM research about his work on Fully Homomorphic Encryption (FHE). FHE allows for computation on encrypted data. First developed in 2009 at IBM, this tech has long been the considered only theoretically possible. However, as we learn in the interview, there have been strides made in the last few years and we are starting to see FHE technology being used in some real world applications.

In this episode, we catch up with Sean Bowe and Daira Hopwood from the Electric Coin Company (ECC) to chat about Halo, a recursive proof composition that doesn't require a trusted setup. We cover the efficiency techniques used in Halo such as "nested amortization", how the protocol was developed, what some of the key findings are, and how it fits in with the other recent SNARK-based protocols.

In this episode, we meet with Galen Wolf-Pauly from the Tlon Corporation to discuss the project Urbit. Urbit is an encrypted peer-to-peer network comprised of a deterministic operating system (Urbit OS / Arvo) and a secure, global identity layer (Urbit ID / Azimuth). The Urbit contributors have created new stack, built from the ground up as an integrated system with a focus on user experience.
