Rollup Protocol Security

Architecture

Rollup protocol security fundamentally relies on a layered architecture, offloading transaction execution from Layer 1 blockchains to a separate execution environment, while inheriting the security of the underlying consensus mechanism. This design mitigates congestion and reduces gas costs, enhancing scalability without compromising the base layer’s integrity. Validity proofs, such as zero-knowledge succinct non-interactive arguments of knowledge (zk-SNARKs) or optimistic proofs, are crucial components, verifying the correctness of off-chain computations. The effectiveness of this architecture is directly correlated to the robustness of the fraud-proof or validity proof system and the decentralization of the sequencer.
