In this week's episode, Anna and Fredrik give a general introduction to MPCs, go over a few examples of MPCs in action, compare them with other cryptographic concepts, try to pronounce "fully homomorphic encryption" properly, and more! Here are some of the material that we reference: Andrew Yao's paper on Protocols for Secure Computations "How to play ANY mental game" publication - MPCs first introduced Goldreich-Micali-Wigderson (GMW) Very basic intro to Shamir Secret Sharing and MPCs Video Series from a Prof at Chalmers First widely used MPC in Denmark Multi-Party Computation: From Theory to Practice. Nigel P. Smart speaking at Google Rob Habermeier's Shamir Secret Sharing library A course by Zvika Brakerski on Fully Homomorphic Encryption Thanks again to this week's sponsor Aragon.

In this week's episode, we catch up with Eli Ben-Sasson and Alessandro Chiesa from StarkWare Industries. We talk about their longstanding academic work in theoretic & applied cryptography, how StarkWare came to be, the emergence of zkSNARKs and zkSTARKs, some of the differences between these different zero knowledge systems, dive into the specific features of STARKs (!) and what's coming next in the space.

In this week's episode, we sit down with Jutta Steiner, our friend and Fredrik's CEO at Parity Technologies, to talk about her history in the space, the origin of Parity, the last year in blockchain, and what we see coming in 2019!

We discuss the history of the concept, explore different kinds of Merkle trees, and touch on Radix trees & Patricia Merkle tries. We also look a bit at their usage in both Bitcoin and Ethereum. The topic was a challenging one to explain without diagrams or visuals, so below we are sharing some resources we used in preperation for this episode. We will also be posting this on Github, please feel free to push additional links that might be relevant.

In this episode, Fredrik sits down Martin, who is a Core Dev working on the Geth client and head of security for the Ethereum foundation. They chat about what got him into the space, his interest in security, his entry into blockchain development and, together, they offer some advice for devs wanting to get into this space.

In this week's episode, Anna interviews a number of participants at the ETHSingapore hackathon as part of the ETHGlobal series and tries to get a sense for how these hackers are approaching the space. In this showcase (which was recorded on the Saturday, right in the middle of the hackathon), we asked: What got you into this space? What's your take on singapore? What are you building? and What do you make of the state of Ethereum?

Izaak Meckler and Evan Shapiro from O(1) Labs discuss recursive zkSNARKs, implementing sophisticated scaling solutions, the account-based database model in Coda, compressing transactions with recursive zkSNARKs, architectural choices for performance, and potential applications of zero knowledge proofs.

In this episode Fredrik sits down with Péter Szilágyi, lead developer of go-ethereum to talk about his background, what it means to be a Core Dev and some of the struggles of maintaining an open source project.

In this week's episode, we are joined by a couple greats in the space, Gavin Wood and Vlad Zamfir, to debate the merits of on-chain vs off-chain governance.
