Zero Knowledge

In this week's episode, we sit down with Liz Steininger and Chris Wood from Least Authority to discuss the state of privacy today, the case for private crypto subscription payments and their P4 proposal. The Private Periodic Payment Protocol, P4, uses the shielded account feature of Zcash to provide a fully decentralised method for recurring end-to-end private cryptocurrency payments.

In this week's episode, we sit down with Justin Drake, researcher at the Ethereum Foundation, to discuss randomness in blockchain, how it can be created and what adversarial models exist. We also discuss the random beacon and how that concept has evolved in the development of ETH2.0 Our initial definition of randomness in cryptography comes largely from this article by cloudflare: https://blog.cloudflare.com/randomness-101-lavarand-in-production/ Check out Justin Drake's DevCon 4 talk https://www.youtube.com/watch?v=zqL_cMlPjOI with the slides https://docs.google.com/presentation/d/1VKBMcEMaY6PQjDJK4yAFtxn0vD41eYXW05YA3vdTBsI/edit.

In this week's episode, we invite J. Ayo Akinyele to the podcast. Ayo is a co-Founder of Bolt Labs which will be focused on developing the Bolt Protocol, a privacy preserving layer 2 approach for anonymous micropayments, which is similar to Lightning Network. Bolt, which stands for Blind, Offchain, Lightweight, Transactions, could be used for both scaling zcash or providing a scalable privacy solution for other chains. Here are some additional resources: Original Bolt Paper by Matthew Green and Ian Meiers: https://eprint.iacr.org/2016/701.pdf Bolt description the Electric Coin Company's blog: https://z.cash/blog/bolt-private-payment-channels/ Ayo was on the podcast before in our Zcon0 episode: https://www.zeroknowledge.fm/32 (he features around the 17 minute mark) Here is some additional information about the Lightning Network and the projects Casa Nodes and Bitrefill which are mentioned in the episode.

In this week's episode, we speak with Julian Arni about Radicle, a decentralized alternative to Github built on IPFS. Radicle is both a programming language and a set of tools to enable decentralised open source software development. We go deep into this project, it's hope to impact open source development and also touch on the societal questions that inspired it. Here is a short tweet that summarizes it well.

In this interview, we chat with Rune Christensen from MakerDAO about stablecoins, MakerDAO’s take on this concept, the peg and how this is maintained, security, oracles and more. Here are a few of the terms that we discuss in the episode: DAI: a crypto asset-backed token pegged to the USD  — it is designed to maintain a stable value. MKR: Valuebearing, tradeable token. As a governance token, MKR holders have the responsibility of making risk based decisions that will influence the future health of the system. CDP: The MakerDAO Collateralized Debt Position (CDP) is a smart contract which runs on the Ethereum blockchain. It is a core component of the Dai Stablecoin System whose purpose is to create Dai in exchange for collateral which it then holds in escrow until the borrowed Dai is returned. The best resource we found to explain the CDP is here: https://medium.com/cryptolinks/maker-for-dummies-a-plain-english-explanation-of-the-dai-stablecoin-e4481d79b90 Thanks again to this week's sponsor Neufu

In this week's episode, we sit down with Sam Williams of Arweave to chat about their novel approach to decentralised storage.

Speaking with Boris Mann, Maria Paula Fernandez, Hudson Jameson, Sunny Aggarwal, Yalda Mousavinia, and Peter Mauric, these conversations centre around decision making in the decentralised space, the role of transparency, the different organisations and groups that have formed in Ethereum to help make decisions, how compensation can play a role, the code of conduct, the importance of signaling and much more. Here are some of the groups or initiatives or talks mentioned in the podcast: Fellowship of the Ethereum Magicians Ethereum Cat Herders Rick Dudley's talk at EthCC Tennagraph Signaling Site Ethereum Community’s Code of Conduct Cosmos Protocol blog Autark Aragon Decred If you are looking for some further context for this episode, you may want to check out some previous episodes about governance related topics: Hudson Jameson talks EIPs and Ethereum core

In this week's episode, we sit down with Martin Lundfall from Dapphub & MakerDAO to discuss formal verification - a topic request that comes directly from the Zero Knowledge audience.

In this week’s episode, we sit down with Igor Barinov from POA Network and Austin Griffith from Gitcoin Labs to discuss bridges, xDai - the new side-chain where DAI is the native token - and Austin's super simple Burner Wallet. Bridges are a wide topic and with this conversation we try to give some insight into what they are and how they work. We look at xDai as one concrete example of such a bridged side-chain and Austin talks about his burner wallet that can provide a super snappy nice UX thanks to running on this faster side-chain. A few resources to check out: Burner Wallet website and Github Repo xDai Website As mentioned in the intro, the Zero Knowledge Summit is happening on March 22 - if you are a dev, researcher or founder working on these topics and want to attend, please submit your application here: https://goo.gl/forms/e0DpeHO6kyPVMlIg2) If you like what we do: Follow us on Twitter - @zeroknowledgefm Join us on Telegram - https://t.me/joinchat/B_81tQ57-ThZg8yOSx5gjA Support our G
