About Optimism

Optimism (OP) is an Ethereum Layer 2 scaling solution that uses optimistic rollup technology to provide faster, cheaper transactions while inheriting Ethereum's security guarantees. Launched in 2021, Optimism bundles hundreds of transactions into a single batch submitted to Ethereum, dramatically reducing gas costs. The project has evolved beyond a single rollup into the OP Stack — an open-source, modular framework for building Layer 2 chains. Coinbase's Base, Worldcoin's World Chain, and several other major projects are built on the OP Stack, forming what's known as the 'Superchain' — an interoperable network of OP Stack chains. Optimism operates as the Optimism Collective with bicameral governance: the Token House (OP holders) and Citizens' House (retroactive public goods funding).
