Optimism is a fast, stable, and scalable L2 blockchain built by Ethereum developers, for Ethereum developers. Built as a minimal extension to existing Ethereum software, Optimism's EVM-equivalent architecture scales your Ethereum apps without surprises.

Optimism is one of the layer 2 scaling solutions. It’s powered by a technology called Optimistic rollups, which bundle large amounts of transaction data into digestible batches. Optimism is much cheaper to use than Ethereum, and it’s increasingly becoming popular along with other layer 2s, such as Arbitrum.

Optimism is governed by its eponymous token or OP for short. A portion of the OP supply was airdropped to early Optimism users in late May 2022 in a turbulent launch.

Optimism is a layer 2 chain, meaning it functions on top of the Ethereum mainnet (layer 1). Transactions take place on Optimism, but the data about transactions get posted to the mainnet where they are validated. It’s like driving on a less crowded side street while benefiting from the security of a highway.

Optimism is the second-largest Ethereum layer 2 with a total of $313 million locked into its smart contracts, as of this writing, according to Defi Llama. Arbitrum comes first with $1.32 billion.

Optimism uses a technology called rollups, specifically Optimistic rollups.

They’re called rollups because they roll up (or bundle) the data about hundreds of transactions – non-fungible token (NFT) mints, token swaps … any transaction! – into a single transaction on the Ethereum mainnet (layer 1). When so many transactions are rolled up into a single transaction, the blockchain transaction, or "gas," fee required to pay comes down to only one transaction, conveniently distributed across everyone involved.
