blockchain, decentralisation, nyu, proof of necessary work, proof of stake, proof of work, snarks
In this week's episode, Anna and guest host Tarun Chitra chat with Akis Kattis, a PhD student at NYU & the co-author of Proof of Necessary Work: Succinct State Verification with Fairness Guarantees - a paper he co-wrote with Joseph Bonneau. They discuss the challenge of Proof of Useful Work, the unique properties that SNARKs have, such as puzzle hardness, that allow for PoNW to overcome these challenges, PoS SNARK systems, elastic block construction, and more.

blockchain, decentralised ecosystem, governance, proof-of-stake, tezos, zero knowledge proofs
In this week's episode, Anna interviews three people from the Tezos community: Jacob Arluck (co-founders TQ ), Marc Beunardeau and Marco Stronati (both from Nomadic Lab). They chat about the Tezos origin story, the development of the PoS system, the governance of Tezos, and how they are incorporating zk proofs - and specifically Sapling from Zcash - into their system.

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.

blockchain, eth2.0, ethereum, privacy, research, scaling, tech, zero knowledge proofs
In this episode, we catch up with Justin Drake and Vitalik Buterin from the Ethereum Foundation to chat about how zero knowledge proof systems are being used throughout the Eth1x and Eth2.0 stacks. We look at their applications for privacy and scalability throughout layers 1, 1.5 and 2, as well as explore some other emerging 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.

In this week's episode of the podcast, we catch up with Alex Glukowski of Matter Labs to hear about zkSync, the latest iteration of their zkRollup implementation built to be a scaling and privacy engine for Ethereum. We also touch on the Redshift protocol, a new transparent zkSNARK system that emerged as a result of their work on this system.
