In this episode, we chat with Tarun Chitra about a broad range on topics, from his work on early non-blockchain ASICs, to making models in high frequency trading, and the nuances of statistical modeling of PoS systems in blockchain.Tarun's new company Gauntlet is building a simulation platform for crypto networks to help developers understand how decisions about security, governance and consensus mechanisms are likely to affect network activity and asset value.Here are a few of the articles that we discuss: On Bitcoin and Red BalloonsSecure High-Transaction Rate Processing in BitcoinWe also mention a previous episode with Axel Ericsson from Vest that you can find here --> https://www.zeroknowledge.fm/49For a bit more about Tarun, follow him on Twitter, or check out this Vice Article about his past work at D.E.

In this special 50th episode, we invite our friend Zooko to the podcast to chat about his background and explore the history of Zerocoin and Zcash. We dig into the inner workings of Zcash, the trusted setup, the sapling upgrade, and what the future of the project might look like!The Sapling upgrade promises to reduce the proving times of the zk-SNARKs from 37 seconds to 2.3 seconds by replacing the SHA256 hash function with an improved performance Pedersen hash function called Bowe-Hopwood Pedersen, introducing an updated eliptic curve (Groth16/BLS12-381), moving from Libsnark to Bellman, and using a new split circuit design.

In this episode, Griff Green shares his experience of working through The DAO hack, the white hat hacker group & Giveth.Through his telling of this story, we are given a front row seat to one of the most exciting events in ethereum and general blockchain history. These events also set the stage for a lot of the decisions, attitudes, rifts and relationships that have since taken hold - from the emergence of the white hat hacker group, the currency split, to the attitude towards governance and immutibility and the community's attitude towards the very concept of a DAO. The story leads us to Griff's latest project Giveth, an ethereum-based project that aims to bring back some of the most inspiring ideas from the era of the DAO, and applies them towards charitable giving.

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, 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.

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. DFINITY Website: https://dfinity.org/DFINITY Github: https://github.com/dfinity

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.

In this episode, we sit down with John Palmer and Marcus Molchany to discuss their new project Pragma, a tool designed to make deploying smart contracts much easier for developers who are new to the space.We also delve into programming languages and the role of testnets and talk about the challenges of staying agile and testing assumptions when you're dealing with immutable technology.
