Digging into Mining with Kristy-Leigh Minehan Jul 14, 2021

Show notes

This week, Anna chats with Kristy-Leigh Minehan, a crypto and mining veteran primarily known for developing the ProgPow hashing algorithm. She offers a unique and in-depth perspective into the world of Proof of Work mining, starting from the early days of Bitcoin and moving into the first Bitcoin ASICs, the Ethereum GPU mining era, all the way to the present day of staking dominance.

Some of these stories come from Kristy’s direct involvement in Genesis Mining, Core Scientific, ProgPow and her connection to the Ethereum mining community, which helps shed light on what miners will do after the Merge.

Analyzing Osmosis & Preventing MEV with Sunny and Dev Jul 07, 2021

Show notes

This week, Anna and Tarun chat with Sunny Aggarwal and Dev Ojha about their new project Osmosis, an AMM built into the Cosmos ecosystem using the IBC interoperability protocol.

Osmosis brings some interesting innovations to the AMM table, starting from the seamless IBC integration to customizable bonding curves and per-pool governance to promote experimentation. Sunny and Dev are also very passionate about the topic of MEV, diving into the various types of value extraction, how MEV is mitigated on other networks and how it could be largely eliminated on Osmosis through threshold cryptography.

ZKPs for Spam Protection & Decentralized Messaging with Status Jun 23, 2021

Show notes

This week, Anna chats with Oskar Thoren and Sanaz Taheri-Boshrooyeh from Status to learn about their work on Waku, a decentralized messaging protocol incorporating zk-SNARKs for spam protection. Waku is the successor of Whisper, a messaging protocol that turned out to be too resource-heavy and vulnerable to spamming.

Oskar and Sanaz explain how Waku V2 changes things, from ZKP-based spam protection to how its new networking system based on libp2p and Gossipsub can scale globally.

This week Anna and Tarun host Noah Zinsmeister and Moody Salem to learn all about Uniswap and the recent Uniswap V3 deployment.

Noah and Moody go through the history of Uniswap from its EF grant days to Unisocks, Uniswap V2 and now Uniswap V3 and its ranged liquidity model. They explain all the benefits as well as the potential drawbacks, and how the project plans to fix them in a likely indirect way. At the end the conversation shifts into a multi-L2 deployment future and how that may increase MEV, leading Tarun to make an unexpected realization.

The dive into ZK with Iron Fish’s Elena Nadolinski May 26, 2021

Show notes

This week Anna and James chat with Elena Nadolinski, founder of Iron Fish, about the new privacy network and what led her to this point.

Elena recounts her journey into crypto, starting from AirBnB and falling into the rabbit hole of Ethereum hackathons, Solidity, and NFTs, eventually leading her to exploration of zero knowledge proofs for honest computation. This deep dive into SNARKs and Sapling led to the creation of Beanstalk, later Iron Fish, which aims to be the shielded pool for all other blockchain assets.
