cryptography, european privacy, mixnets, nym, privacy technology, privacy-preserving, zero knowledge
In this episode, Anna catches up with Claudia Diaz, professor at KU Leuven and the Chief Science Officer at Nym Technology to learn about mixnets, the history of privacy technology and how there may be some opportunities for new privacy tech to emerge in this post-pandemic world.

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.

ecc, electric coin company, halo, recursive snarks, trusted setup, zcash, zero knowledge
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.

cryptography, isogenies, multi-party computation, polkadot, web3 foundation, zero knowledge, zero knowledge proofs
In this week's episode, we sit down with Alistair Stewart and Jeff Burges, researchers at the Web3 Foundation, to dig into what they are working on, what they are thinking about at the moment, and how zero knowledge proofs can be used throughout the Polkadot ecosystem.

cryptography, fractal protocol, math, recursive snarks, uc berkeley, zero knowledge, zksnarks
This week, we explore the Fractal transparent SNARK construction with its authors Dev Ojha and Nick Spooner - both students of Alessandro Chiesa at UC Berkeley. In this episode, We explore how Fractal works, how it improves on some of the earlier work on Sonic and Marlin, how it borrows from but differentiates itself from STARKs, as well as what they discovered while working on this paper about recursive SNARKs and what makes that property possible.

aztec protocol, cryptography, lagrange-bases, plonk, polynomial commitments, zero knowledge
In this week’s episode, we learn more about Plonk with Ariel Gabizon and Zac Williamson from Aztec. PLONK is an efficient, universal SNARK construction. We explore what distinguishes Plonk from some other other new constructions including their focus on Lagrange-bases to deconstruct complex problem statements into simple polynomial identities.

In this week's episode, Anna sits down with Tarun Chitra (Gauntlet Networks), James Prestwich (Summa) and Georgios Konstantopoulos at the end of the last day of Devcon5 in Osaka. They cover a broad range of topics from their Devcon take-aways, emerging ideas in the ecosystem, the latest in PoS systems, Roll-up and DeFi, to the explosion in zero knowledge research, and more.

beam protocol, blockchain, mimblewimble, privacy, privacy tech, tech talks, zero knowledge
In this week’s episode, Anna sits down with with Alexander Zaidelson and Alex Romanov from BEAM - a Mimblewimble based privacy coin. We discuss how this implementation of the MimbleWimble protocol differs from Grin, how the two groups work together, funding protocol development, how the Beam business model works, and the future of the protocol.

blockchain, grin protocol, mimblewimble, privacy, privacy tech, tech talks, zero knowledge
In this week’s episode, we chat with Daniel Lehnberg about Grin - an implementation of the MimbleWimble privacy protocol. We cover the story behind MimbleWimble, how Grin first came to be, and how this technology works. We also look back at how this protocol came to be as well as were Daniel sees it going.
