# Optimistic Rollups ⎊ Area ⎊ Resource 1 --- ## What is the Architecture of Optimistic Rollups? Optimistic Rollups represent a Layer 2 scaling solution for Ethereum, functioning by executing transactions off-chain while leveraging Ethereum’s security for data availability and fraud proofs. This design inherently reduces on-chain congestion and associated gas costs, facilitating higher transaction throughput without compromising decentralization. The core principle involves assuming transactions are valid unless challenged, a process that relies on a dispute resolution mechanism involving validators and a fraud proof system. Successful challenges revert invalid state changes, ensuring data consistency across the Layer 2 and Layer 1 environments, and this approach is critical for maintaining trustless operation. ## What is the Calculation of Optimistic Rollups? The economic security of Optimistic Rollups is fundamentally tied to the cost of submitting and verifying fraud proofs, influencing the incentive structure for potential attackers. A rational attacker must weigh the potential gains from fraudulent activity against the expense of constructing and successfully executing a fraud proof on the Ethereum mainnet. This calculation involves assessing gas costs, the time required for proof verification, and the probability of detection, creating a dynamic equilibrium between security expenditure and attack profitability. Consequently, the efficiency of fraud proof systems directly impacts the rollup’s security budget and overall scalability. ## What is the Risk of Optimistic Rollups? Implementing Optimistic Rollups introduces a withdrawal period, during which funds are locked to allow for potential fraud challenges, representing a temporary liquidity risk for users. This challenge period, typically spanning several days, necessitates careful consideration for traders and applications requiring immediate finality. Furthermore, smart contract risk within the rollup environment remains a concern, as vulnerabilities in Layer 2 contracts can lead to fund losses, despite the underlying security of Ethereum. Mitigating these risks requires robust auditing practices and the development of sophisticated monitoring tools. --- ## [Frontrunning](https://term.greeks.live/definition/frontrunning/) Executing a trade before a known pending order to profit from the expected price movement caused by that order. ⎊ Definition ##
