[Optimism](https://www.optimism.io/) is a Layer-2 scaling network for Ethereum that operates under a four-pillar design philosophy of [simplicity](https://docs.optimism.io/stack/protocol/design-principles#simplicity), [pragmatism](https://docs.optimism.io/stack/protocol/design-principles#pragmatism), [sustainability](https://docs.optimism.io/stack/protocol/design-principles#sustainability), and [optimism](https://docs.optimism.io/stack/protocol/design-principles#optimism). Optimism [aims](https://help.optimism.io/hc/en-us/articles/4411894310427-Why-use-Optimism-) to increase Ethereum’s transaction throughput while decreasing the cost of transacting on the network. This is achieved through [Optimistic Rollups](https://docs.optimism.io/stack/protocol/overview), which [allow](https://help.optimism.io/hc/en-us/articles/4413163242779-What-is-a-rollup-) transactions to be executed on [OP Mainnet](https://twitter.com/optimismFND/status/1672281032962478080), Optimism’s blockchain, while relying on Ethereum for settlement, consensus, and data availability.
