Ethereum rollups offer significant security benefits by leveraging the underlying security mechanisms of the Ethereum mainnet, ensuring that transaction data remains tamper-proof and highly secure. Optimistic Rollups rely on a challenge period for fraud detection, maintaining security through economic incentives, while Zero-Knowledge Rollups use cryptographic proofs to validate transactions without revealing their contents, enhancing privacy and security. Ethereum is leveraged for its data availability, and as a mechanism to perform dispute resolution.
