Layer-2 Security

Definition ∞ Layer-2 security refers to the protective measures and protocols implemented on secondary frameworks built atop a primary blockchain, designed to enhance scalability and efficiency. These solutions, such as rollups and state channels, inherit security guarantees from the base layer while processing transactions off-chain. Understanding layer-2 security is critical for assessing the safety and reliability of decentralized applications operating at higher transaction throughputs.
Context ∞ The current discourse on layer-2 security is largely focused on the robustness of fraud proofs and validity proofs, the cryptographic mechanisms ensuring the integrity of off-chain computations. Discussions address the potential attack vectors unique to these scaling solutions and the effectiveness of their respective security models. Critical future developments to watch include the standardization of security audits for layer-2 protocols and the demonstration of their resilience against sophisticated adversarial attacks.
