This week, I - Hasu - talk to Andre Cronje, a long-time DeFi developer, and creator of Yearn Finance. You can think of Yearn as a smart bank account that automatically allocates your assets to different low-risk investment strategies that execute on the Ethereum blockchain.
My co-host is Tarun Chitra, the CEO and founder of Gauntlet, a company that helps stress test the incentive structures and economics of cryptocurrency protocols, especially of DeFi protocols.
We're releasing this interview in two parts. The first gives you an introduction to Yearn Finance, it's future, and Andre's design and investment philosophy in building it. Part II explores the design space for governance systems in DeFi - one of the hottest topics in crypto right now.

Interview with Andre Cronje, Part 1 - with Hasu and Tarun Chitra

Uncommon Core 2.0 is a crypto research podcast. This show goes beyond speculation and investing, looking deeper. We explore the fundamental technology and incentives that make public blockchains work under the hood. This show is co-hosted by Hasu and Jon Charbonneau. They’ll be joined by occasional guests, speaking with some of the incredible builders and researchers who are looking to evolve this infrastructure stack to make the mass adoption of crypto possible.

Hasu and Jon bring on Ansgar and Caspar from the Ethereum Foundation to discuss the ETH staking endgame. 
 
Ansgar and Caspar recently published two controversial research posts which included a proposal to change Ethereum’s issuance curve. They are concerned that the current ETH staking economics could lead to nearly 100% of ETH being staked, with much of that in LSTs. They propose reducing issuance and targeting a lower stake rate.
 
We go deep in this episode on PoS economics, liquid staking, restaking, economic security, centralization concerns, and much more.

Ethereum’s Staking Endgame

Hasu and Jon catchup on what’s new in the EVM (Ethereum Virtual Machine) and SVM (Solana Virtual Machine) worlds. 


For the EVM, Ethereum has pushed vertical scaling efforts to other chains. This includes Monad, who is building a new EVM L1 with fundamental optimizations to improve scalability. 


For the SVM, the Solana ecosystem continues to gain momentum across the board. Meanwhile, Eclipse is gearing up to launch their SVM Ethereum L2. 


DBA is an investor in Eclipse Laboratories, Inc. and SOL. Jon has material personal investments in SOL, JitoSOL, ETH, stETH, and TIA. Hasu has material personal investments in ETH and Monad.

SVM vs EVM

Hasu and Jon bring on Mike Neuder (Ethereum Foundation) and Chris Hager (Flashbots) to discuss the design philosophy of proposer-builder separation (PBS). They first dive into the past and present implementations of PBS, including MEV-Geth and MEV-Boost on Ethereum. Then they discuss the future of PBS - whether PBS should be enshrined, protocol-enforced proposer commitments (PEPC), PBS on L2s, how to prevent censorship, and more.

An Incomplete Guide to PBS - with Mike Neuder and Chris Hager

In this episode, we explore Jon’s journey into crypto and our mutual passion for research and the writing process. We then give an overview over the key areas of crypto infrastructure today. Finally, we zoom into rollup decentralization roadmaps, and Jon shares a controversial new thesis about sequencer decentralization.

How will Rollups Decentralize? Proof-of-Governance and more

Listen to conversations between two veterans of the crypto industry: Su Zhu, CEO and CIO of Three Arrows Capital, and Hasu, Strategy lead at Flashbots. Exploring the big ideas in crypto from first principles.
In this episode, Hasu continues the conversation with Danny Ryan and Tim Beiko, two researchers from the Ethereum Foundation. The three are joined by Stephane Gosselin, co-founder of Flashbots, who makes his podcast debut and stands in as Hasu's co-host. 
Together, they discuss:

 MEV before and after the Merge
 mev-boost and proposer-builder-separation (PBS)
 The rise of liquid staking pools
 Whether Lido should cap its own growth
  How the Ethereum Foundation sees its role in interacting with very "protocol-adjacent" projects like Flashbots + Lido
