blockchain, crypto, cryptography, findora, privacy tech, supersonic, zero knowledge, zkps
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.

contract tracing, covid-19 privacy, cryptography, dp-3t, europe technology, privacy tech
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.

blockchain, consensus, consensus protocols, cryptography, hotstuff, libra, proof of stake, vmware
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.

contact tracing, coronavirus, crypto libraries, cryptography, pandemic, privacy, privacy tech, tcn coalition, zcash
In this week's episode, we chat with Henry de Valence from the Zcash Foundation. We discuss what makes for a strong crypto library, some of the work he has been doing at the ZF and he shares an update about the Zebra Zcash client. We also learn about the TCN Coalition, a group he is working with that aims to build and evaluate privacy-preserving contact tracing protocols - an important tool in the fight against the coronavirus pandemic.

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.

blockchain, cryptography, isogenies, math, morphisms, tech education, vdfs, verifiable delay functions
In this week’s episode, we dive into Isogenies - a topic at the cutting edge of cryptography. We look at how they are related to VDFs and randomness generation. Our guest, Luca de Feo, one of the co-inventor of SIDH, helps us get an understanding for what Isogenies - or morphisms of algebraic groups - really are.
