Watch a comprehensive technical talk exploring how Ethereum's transition to Proof-of-Stake fundamentally transformed the economic relationships between protocol stakeholders. Delve into the complex web of protocol boundaries, validator responsibilities, and economic incentives in the post-Merge Ethereum ecosystem. Learn about principal agent problems, dynamic transaction pricing, EIP1559, proposal builder separation, and the implications of liquid staking. Examine the evolving builder market, censorship risks, net neutrality considerations, and the broader impact on protocol decentralization. Understand how these economic transformations affect network resources, validator rewards and penalties, and the future of cross-chain interactions. Gain insights into the technical and economic challenges of improving stake efficiency, restaking mechanisms, and maintaining protocol neutrality in the brave new builder world of Ethereum.
