Optimism (OP) is a Layer 2 (L2) scaling solution developed to
address Ethereum's scalability challenges.
Optimism is responsible for developing and operating the OP

A roll-up is a blockchain that derives its security from a
higher-level chain.
Ethereum serves as the parent chain for Optimism.
Optimism leverages Ethereum to:

reducing costs.
Utilize Ethereum's robust security for enhanced protection of
data and transactions.
