Optimism (OP Mainnet) is a Layer 2 optimistic rollup chain on Ethereum that processes transactions off-chain and posts batched data to L1 for settlement. The rollup inherits Ethereum security through fraud-proof verification, where invalid state transitions can be challenged within a withdrawal period. Developers deploy unmodified Solidity contracts with reduced gas costs while users access decentralized applications at significantly lower fees than mainnet.
