In this episode, we sit down with Lane Rettig and Alex Beregszaszi from the eWasm team at the Ethereum Foundation to talk about WebAssembly (Wasm). We explore why Wasm was chosen as the instruction set of the future for Ethereum, what it means to switch instructions sets and why you would want to go with one over another. We also dig into Wasm specifics and tooling. If you want to learn more about Wasm, check out some of the links below: Official Wasm website eWasm design repo where there are documents discussing the different VMs as well as goals, motivations and design specs of eWasm. K Framework description

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 site IC3 Cornell Tech Project chicago Gas Token

In this special episode, we share a number of short interviews we did with the participants of the Web3 UX Unconference which followed Edcon last week in Toronto. Featuring Dan Finlay from Metamask, Alex van de Sande from the Ethereum Foundation, Ric Burton from Balance, Philippe Castonguay, Jonny Howle from Uport, Dan Tsui and Bryant Eisenbach, we explore the topic of UX in the blockchain space.

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 FAQ Parity 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.

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.

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.

In this episode, Anna speaks with Niraj Pant and Karthik Raju, the research team at Polychain Capital, about the work, their background and the projects they are excited about. Polychain Capital is one of the world's premier funds managing a portfolio of blockchain assets. Follow: Polychain Capital Niraj Pant

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 Floersch Phil Daian Plasma

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.

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.

The gang catches up on what's been going on in the blockchain world for the past month, sharing some nuggets of learning around bloom filters, Proof of Authority, upcoming events, the Dfinity paper and some comments on what all the fuzz around this ERP is.

In this episode, we talk about what it takes to be a blockchain developer. Fredrik shares some of his insights and interviews Gavin Wood, co-founder of Parity and Ethereum, about how he got into this space as well. We also dig into what properties a good blockchain developer should have.
