    Episode 152: Blockchain analytics with Alex Svanevik from Nansen

    Episode 152: Blockchain analytics with Alex Svanevik from Nansen

    In this week’s episode, guest host Tarun Chitra and Anna chat with Alex Svanevik, CEO & cofounder of Nansen. They cover crypto analytics, DeFi analytics as well as discuss the push and pull between a need for privacy and the need for blockchain transparency and data.


    Topics include: can DeFi and Privacy co-exist, how being aware of blockchain analytics could help people improve their opsec, the role of reputation in these systems, and, finally, how analytics in public blockchains may used as a novel marketing tactic (eg. when someone purposefully makes a big buy, knowing sophisticated traders are following their every move using these analytics tools and will see this as a signal to buy as well).

    Aleo is the first platform for fully private applications. It uses blockchain and zero-knowledge cryptography to deliver a web experience that is both personal and private. With Aleo, developers can write private applications, without a background in blockchains or expertise in cryptography.


    Aleo has released Developer Preview I, an early peek at what the future of the web will look like. The release introduces a new programming language called Leo, a new community-driven package manager for Leo, and a new development environment or IDE called Aleo Studio.

    In this episode, we chat with John Adler - co-founder of Lazy Ledger and Fuel Labs. We compare Optimistic Rollups and ZK Rollups as well as discuss how Ethereum, specifically Eth1, could look over the next few years. We also talk about the data availability challenge in blockchains and how Lazy Ledger aims to solve this.

    Episode 150: NFTs & Rarible with Alex Salnikov

    Episode 150: NFTs & Rarible with Alex Salnikov

    This week, Anna continues to dig into the topic of NFTs - That is Non-Fungible-Tokens or unique digital items - with Alex Salnikov, co-founder & chief product officer at Rarible. They talk about the project, the link between NFTs and DeFi concepts, how the NFT space is developing, novel use cases and more.


    Here are some of the topics we mention:
    The path to an ERC standard
    CryptoKitties, Dapper Labs and Flow with Dieter Shirley
    Somnium Space VR
    0x Cert
    Centrifuge




    Thank you to this week’s sponsor Trail of Bits.


    Trail of Bits has published a new guide for building secure contracts with their Crytic offering.
    Crytic is a SaaS-based GitHub application created by Trail of Bits that continuously assures your Ethereum smart contracts are safe and functional. It reports build status on every commit and runs a suite of security analyses so you get immediate security feedback.


    Check out this guide - which I have added to the show notes - for tips on how to build security into your dapps from the start and how to use the Trail of Bits suite of tools for automated vulnerability detection.


    Thank you once again Trail of Bits

    Sushiswap Bonus Chat

    Sushiswap Bonus Chat

    This is a short bonus chat to Episode 148 "Tale of the Sushi(swap)". Tarun, Hasu and Anna reconvene to wrap up the story of Governance Tokens, Sushiswap and the Uniswap token distribution.

    "Tale of the Sushi(swap) - Part 1"
    "Tale of the Sushi(swap) - Part 2" on the uncommoncore podcast

    Episode 148: A Tale of Sushi(Swap) with Tarun, Hasu and Anna - Part1

    Episode 148: A Tale of Sushi(Swap) with Tarun, Hasu and Anna - Part1

    In this special podcast crossover episode, Tarun, Hasu and Anna cover the emergence of governance tokens in the DeFi space and then dive deep into the Sushiswap story - what protocols came before and how it performed a vampire attack on (what was at the time) a tokenless Uniswap. This story acts as a fascinating case study as well as a cautionary tale for moat-less protocols.


    This episode is the 1st of 2 parts, with the 2nd part airing on Hasu's Uncommon Core podcast. 


    In this part, we cover the definition of governance tokens and the first half of the sushi swap story.


    Tarun also mentions "impermanent loss" in this episode. However this term has been called to "divergence loss" and you can read more about what it is here.


    A quick caveat: We recorded this episode just hours before the Uniswap token launch, and so we decided to produce an amendment section to tackle the aftermath of the launch and wrap up the story. You can find this here:

Best Crypto Podcast

This is the best crypto podcast out there, and I have listened to five different podcasts semi-religiously. The hosts do a great job of covering the more technical aspects of the space in a way that is still accesible to non-technical individuals

Oshkoshbijosh ,

Great for Crypto Info

Definitely worth your time if you're trying to stay in the know.

a13xndra ,

Really helpful for better understanding blockchain technology

Zero Knowledge covers the technical and development side of blockchain technology in an approachable but sophisticated manner. I like that it's legitimately about curiously exploring the space... nobody's shilling their service, it's not about price or politics... just investigating tech and development. The podcast has been fundamental in growing my technical understanding. Fredrik and Anna ask great questions — Fred asks more technical developer questions, Anna covers the questions that I would probably ask as a non-dev.

My favorite episodes so far:
3 - hard forks
15 - consensus algorithms
17 - plasma and storage rent
