Rollup Architectural Risk

Definition ∞ Rollup architectural risk refers to potential vulnerabilities or limitations inherent in the design and implementation of a Layer 2 rollup scaling solution. These risks can include issues related to data availability, sequencer centralization, censorship, or the security of the fraud or validity proof mechanisms. Such risks can compromise the integrity, liveness, or censorship resistance of the rollup.
Context ∞ Rollup architectural risk is a significant concern for the long-term viability and security of Layer 2 ecosystems. The current discussion involves continuous auditing, formal verification, and community scrutiny of rollup designs to identify and mitigate these vulnerabilities. A critical area of development is the ongoing work to decentralize rollup components, such as sequencers, and to enhance the robustness of their underlying cryptographic proofs and dispute resolution systems.
