Zero Knowledge

In this week's episode, we share our interviews from ETHBuenosAires, the 3rd instalment of the ETHGlobal Hackathon series. Through these conversations with the participants, sponsors and organizers, we found out more about the Buenos Aires Blockchain scene, captured the spirit of the ETHGlobal series and learned about some amazing new ideas and hackathon projects This was recorded during the event, but you can watch the winners presenting HERE More links:EthBuenosAires Website & Twitter Kimono Crypto Against Humanity DenodeToken Toilet Other projects that were mentioned:http://www.thegraph.com/ All Submissions can be seen hereFollow the peeps we interviewed on twitter:https://twitter.com/cryptowanderer https://twitter.com/ethstatus https://twitter.com/licuende https://twitter.com/AragonProject https://twitter.com/MakerDAO https://twitter.com/komodoman https://twitter.com/liamihorne https://twitter.com/nanexcool https://twitter.com/gomox_ar https://twitter.com/crypt0glitter https://twitter.com/pfletcherhill https://twitter.com/eordano

Coming to you from Buenos Aires, we sit down with Demi and Facu from Zeppelin Solutions to talk developer experience, upgradability and how they aim to make running software on blockchains simple, fast and error free. We discuss their products - OpenZeppelin, a framework of reusable smart contracts, and ZeppelinOS, an operating system designed specifically for smart contracts - and how these projects have emerged from their work as auditors on some of the most important projects in the space. They introduce their proposal for upgradability, a method for making some alterations to existing smart contracts without impeding immutability.

In this episode, we catch up with Phil Daian once again to dig deeper into the idea of cryptocommodities and storage rent. Cryptocommodities are defined as the resources used for blockchain transactions - for example blockchain memory or computation (such as Ethereum's gas) - and storage rent is the idea of issuing a payment for use of these resources per unit of time instead of as a one-time fee.We discuss how the storage rent idea is becoming increasingly relevant as blockchain technology becomes more widely adopted, and the challenges in implementing this into existing systems. Phil is a researcher with IC3 and PhD student at Cornell Tech as well as the creator of GasToken and member of Project Chicago. Some links:Phil's siteIC3Cornell TechProject chicagoGas Token

In this episode, we share an introduction to full nodes. Speaking with the Parity community support lead, Thibaut Sardan, we walk through what it means to set up the Parity Ethereum client, explore what the difference is between this and a light client, help define some of the commonly used language and answer some frequently asked questions. Big thank you to 1kx for inviting us to the Full Node co-working space to record this episode! Links:Parity FAQParity UI and Light Wallets

In this weeks episode, Fredrik and Anna speak with Elias Haase and Rob Hitchens from B9Lab about how a curriculum can be developed to introduce developers to the concepts and languages in the blockchain space. We discuss some of their process, the unique qualities of teaching in this space and how important it is that the people building core infrastructure consider the impact of their decisions on society in the future.Links:B9Lab on TwitterB9LabBe sure to follow us on twitter @zeroknowedgefm

In this episode, we kick off the Zero Knowledge Proof series with our very own 'Intro to Zero Knowledge' in which we go through a couple examples that describe the underlying concept of this important field of research.Basically, the Zero Knowledge hosts are talking about Zero Knowledge Proofs on the Zero Knowledge Podcast. It promises to get meta. Links:Where's Waldo exampleStr4d presenting the Billiard Balls example at ZK0x01Sudoku ZKP exampleEli Ben Sasson presenting STARKs Read transcript

In this episode, Fredrik sits down with Jon Choi from the Ethereum Foundation to discuss the latest scalability grants and what the plans are for the Ethereum Foundation grants in general.We also delve into what a business model for core infrastructure could mean and how to avoid the tragedy of the commons where no one is willing to invest in vital infrastructure because of the lack of immediate incentive.Finally, we discuss the general ecosystem, how we can learn from each other, how and what to build and what's needed before Ethereum can really become a platform suitable for mass adoption.

We welcome Jack back to the show to discuss what's been going on in our world for the past month. We share a little review of our recent event - the Zero Knowledge Summit - and an update from the Taiwan Sharding Workshop. We also discuss the role of testnets and explore the purpose and practice of ASIC resistance.Links to things talked about in the episode:Fredriks talk about Rust smart contracts & wasmEthereum Sharding Research CompendiumZero Knowledge Youtube channelZero Knowledge Twitter account (stay up to date folks)ASIC resistance EIPPhil Daian's (previous guest) blog post response to hard forking for ASIC resistance

Plasma is a new type of scaling solution that Karl is helping to develop, and Phil tries to tear it apart. Phil also introduces the topic of storage rent, which is an uncomfortable truth we'll have to face sooner rather than later.We sit down and try to dig through and define what Plasma is, what the pro's and con's are and what potential use-cases the technology has.Unfortunately, the second half of the storage rent conversation was lost, but what's there is still valuable enough to share. Hopefully we can get another episode with Phil to dig deeper into the topic.Karl FloerschPhil DaianPlasma

This week we sit down with JP Smith from the software security firm Trail of Bits. Trail of Bits started as a traditional infosec company doing audits and R&D. Over the past year, the company has been getting into doing audits and building tools for the blockchain space.We talk about what audits are and how to think about them, how you should work to secure your smart contracts using Trail of Bits tools along the way and share some stories and conversations from the world of security.Links to some of the tools talked about in this episode:manticoreethersplayechidnanot-so-smart-contracts

Fredrik has a chat about consensus algorithms with Parity Technologies in-house consensus expert Robert Habermeier. We cover what a consensus algorithm is and how they work. We try to explain some common terms like safety and liveness, what a fork choice rule is and how real-world constraints like networking play a role in your algorithm design.--Robert Habermeier

In this episode, we do a deep dive into the DFINITY protocol project and their recently released whitepaper. Using a randomness beacon, DFINITY aims to achieve an efficient and fair PoS system with strong safety and liveness guarantees. We speak with Robert Lauko, a Research Associate working on the project, about the ongoing development of this new blockchain, the Blockchain Nervous System and DFINITY's approach to on-chain governance.

In this episode, we will be talking with Liz Steininger, the CEO and MD of Least Authority - a Berlin based company focused on building an affordable, ethical, usable, and lasting data storage solution. They are dedicated to Free and Open Source software, end-to-end cryptography, user-friendly interfaces, and a sustainable economic model.We sat down to discuss her experience with decentralised communities, the challenges of open source technology and how the blockchain dev community will likely develop over the next few years.

In this episode, we invite André, a Parity dev, to join us in a review of the latest activity in Parity and the general blockchain space. We cover bootnode infrastructure, database issues, the updated yellowpaper and more.

Part 2 in our series on decentralized storage: Solutions. In this episode, we look at the problems decentralised storage are trying to solve, interesting projects trying to tackle these problems and some of the implications. We also have a look at what properties you should keep an eye out for when looking at decentralized storage solutions and what you may want to consider before jumping into mining.

Part 1 in our series on decentralized storage: Looking back. Fredrik and Anna talk about some history and memories of peer-to-peer technology, file sharing and decentralized storage.We dig into our own history and involvement with p2p technology, file sharing, how it rose to fame and then disappeared into the cold P2P winter.

In this episode, Anna and Fredrik have a look back at 2017 and the changing blockchain ecosystem with ex-Ethereum Foundation and current-Parity core dev, Marek Kotewicz. We also share our predictions about what we can expect to see next year in crypto land. FYI: opinions are our own, and we definitely won't be giving financial advice :PBlocksize research: https://www.bitcoinunlimited.info/resources/1txn.pdfParityDB: https://github.com/paritytech/paritydb

In this episode, Anna and Fredrik are joined by 3 fellow Parity employees to talk about what first got them interested in blockchain and the whole decentralised scene, how the greater community has evolved over the last few years, and what we can expect for the coming year.Our guests:Afri, Community Manager, Support and all around contributorMaciej, Core DeveloperFabian, Business Development

We talk about what we've been working on for the past week and what's been going on in the community and our lives.

We go over what Hard Forks are, what they mean and what this particular one, Byzantium, brought to Ethereum.

Wherein we talk about Proof of Work, what it is and how it has developed and why we want or might not want Proof of Stake instead.

Jack, Anna and Fredrik talk about their experience at RustFest 2017 in Zürich.Parity Technologies was one of the main sponsors and so we went there with a crew and had a booth. Many interesting conversations were had, along with great talks.
