At CSS 2023, Pellegrino discussed the complexities and challenges of cross-chain messaging protocols, particularly emphasizing the principles of immutability, permissionless-ness, and censorship resistance as fundamental to their success. Pellegrino noted that while cross-chain messaging protocols had experienced exponential growth in message transactions, many were built on increasingly centralized systems that presented risks, including susceptibility to hacks. He emphasized that many existing protocols provided merely a service rather than a decentralized protocol, which can lead to potential security vulnerabilities when systems allow for contract upgrades. Highlighting past incidents, such as the Nomad hack, he pointed out that code upgrades could inadvertently introduce critical issues. Additionally, he analyzed how permissionless and censorship-resistant systems contribute to security while cautioning that any ability to censor could ultimately be exploited. Pellegrino concluded that when assessing cross-chain messaging protocols, developers should consider their ability to safeguard against these vulnerabilities while maintaining open, reliable communication across different blockchain infrastructures.
