Rollup security refers to the measures and protocols employed by Layer-2 scaling solutions, known as rollups, to ensure the integrity and finality of transactions. These solutions process transactions off the main blockchain but derive their security from the underlying Layer-1 network. The robustness of rollup security is critical for user trust and asset protection.
Context
The security posture of various rollup solutions is a subject of intense technical and market scrutiny, particularly concerning their ability to guarantee data availability and prevent fraudulent state transitions. Discussions often involve the comparative strengths of optimistic rollups versus zero-knowledge rollups and the development of standardized security audits. The ongoing advancements in rollup security are pivotal for the scalability and long-term viability of blockchain networks.
Research reveals "optimistic MEV" as a dominant L2 arbitrage, where speculative on-chain probing crowds out user transactions and exposes rollup security vulnerabilities.
