FRAUD PROOF WARS

Summary from the TLDR Crypto newsletter

Optimistic rollups face a fundamental trilemma, making it difficult to design safe systems with fixed delays that rely on a 1-of-N honest assumption, primarily due to the risk of resource exhaustion attacks. This article examines the fraud proof designs of projects like Arbitrum, Cartesi, and Optimism, and questions the viability of fraud proofs in a zero-knowledge (ZK) context.
