About
Optimism is an Ethereum Layer 2 using Optimistic Rollup technology ,processing transactions faster and cheaper while settling on Ethereum mainnet. Founded by Ethereum Foundation alumni, it introduced the Superchain vision , a network of L2 chains built on the OP Stack, including Coinbase's Base, Zora, Mode, and dozens more, all sharing security and interoperability.
What makes Optimism unique is its Retroactive Public Goods Funding model ,sequencer revenue funds open-source developers and builders that benefit the broader ecosystem, not just Optimism. With 5 completed airdrop seasons across 2022–2024 and 550M OP still reserved, it runs the most sustained multi-season distribution program in Layer 2 history.
