The article discusses the concept of layer-2 blockchains built on Ethereum and their security features. These layer-2 solutions aim to increase transaction throughput while maintaining the security of transactions. The article explains that “security” in this context refers to settlement guarantees on Ethereum mainnet and the existence of an “escape hatch” to exit with one’s assets. The different methods of validation, such as validity proofs and fraud proofs, are also explained. The article further explores the tradeoffs and challenges associated with implementing these security measures. It mentions the differences between Optimism and zkSync in terms of fraud proofs and technological advancement. The article concludes by discussing the future development and adoption of zero-knowledge technology in the context of security and scalability.
