Optimism is a Layer 2 scaling solution for the Ethereum network that aims to increase its throughput and reduce the cost and latency of transactions. It uses a technology called optimistic rollups, which allows it to bundle many transactions into a single batch and verify them in an efficient and secure manner.

In August 2021, Optimism launched its mainnet, which marked a major milestone in its development. The mainnet launch was preceded by several rounds of testing and auditing to ensure the security and reliability of the platform.
