Zero Knowledge

This week we catch up with Zaki Manian, Director at Tendermint, the company building Cosmos architecture, and co-founder of Iqlusion Validator. We chat about the blockchain in Silicon Valley, why SF loves DeFi, the challenge of balancing pragmatism and regulation with a decentralised ideology, the nuances of PoS systems, the wins of 2019 and what is on the horizon. Here are links to a few things we discuss: -Tarun Chitra's paper on how the existance of derivatives can undermine the security of a PoS system-Blog post summarizing Tarun's paper here-ZKValidatorGive the Zero Knowledge Podcast some feedback.

Lucas Vogelsang, co-founder of Centrifuge, discusses his journey to co-founding the company and the role of privacy in his thinking. They also explore building with zkSNARKs, improving access to finance through blockchain and decentralization, the future of borrowing and lending in blockchain, challenges of scalability on Ethereum, the importance of privacy for businesses on blockchain, and developing in the rapidly changing zero knowledge space.

In this week's episode, we chat with Juan Benet, founder of Protocol Labs, about IPFS, Libp2p, and the much anticipated incentivised decentralised storage protocol Filecoin. We dig into the history of the Filecoin project, the gap in the “market” they are trying to fill, the challenges they have found in the development of the Filecoin protocol and the latest tech they are exploring.

Alan Szepieniec, researcher at Nervos, discusses the Supersonics paper, new hash functions, and the Marvelous universe. They explore trap doors in public keys, transparent snarks, dark compilers, and the historical evolution of ciphers. They also delve into grobner basis attacks and the world of cryptography research.

In this week’s episode, Anna chats with Fredrik and Nicole Zhu, Developer at Parity Technologies, about the experimental Polkadot Canary Network they call Kusama. We cover how Kusama was developed, the goals of this format and what launching a Chaos Canary Network is all about.

In this week’s episode, we sit down with Joseph Bonneau, Assistant Professor at NYU and co-author on the Verifiable Delay Functions (VDFs) paper. We discuss VDFs, what they are, how they were developed and what they can be used for. Here are a few links that we reference: Blockchain 101: Randomness episode with Justin DrakeVerifiable Delay Functions by Dan Boneh, Joseph Bonneau, Benedikt Bünz, and Ben Fischvdfresearch.orgNumbers GameA Programmer Solved a 20-Year-Old, Forgotten Crypto PuzzleBitcoin BookThank you to this week's sponsor Trail of BitsTrail of bit recently released a blog post that might be interesting for our listeners who are concerned about privacy. The post is about the concept of 'Safe browsing'. Safe browsing claims to protect users by providing them with something called k-anonymity. Recent security news suggests that the k-anonymity has failed at protecting user privacy in certain circumstances. This is the topic that Trail of Bits explores in the blog post. Find out more about how k-anonymity works and why it is insufficient here: https://blog.trailofbits.com/2019/10/30/how-safe-browsing-fails-to-protect-user-privacy/If you like what we do: Follow us on Twitter - @zeroknowledgefmJoin us on TelegramSupport our Gitcoin GrantSupport us on the ZKPatreonOr directly here: ETH: 0xC0FFEE1B5083230a5154F55f253B6b6ae8F29B1aBTC: 1cafekGa3podM4fBxPSQc6RCEXQNTK8ZzZEC: t1R2bujRF3Hzte9ALHpMJvY8t5kb9ut9SpQ

In this week’s episode, we chat with Brandon Ramirez, Research Lead and co-founder of The Graph, about the problem the project is trying to solve, the fast evolving Layer1-Layer2 paradigm, the emerging group of Service Protocols, and how these projects interact with other elements of the Web3 stack.
