Exploring the Fraud Proof Trilemma: Challenges in Securing Optimistic Rollups

This is an exhaustive dive into the evolving challenges of optimistic rollups, particularly focusing on the limitations of fixed challenge periods and the need for robust fraud proof systems. It explores the fraud proof trilemma, highlighting trade-offs between safety, promptness, and decentralization in different protocols. The piece also discusses the resource exhaustion attack, its implications on rollup security, and compares various approaches, including Arbitrum's and Optimism's strategies, as well as Cartesi's. It interestingly sparks a conversation around the security and incentives of optimistic rollups.
