Designed around the 4 tenets of simplicity, pragmatism, sustainability and optimism, Optimism uses optimistic rollups to process transactions in batches, reducing gas fees and speeding up transaction time. Optimism is committed to decentralization, right down to the architecture of its own incentive system. With $1M donated thus far, Optimism aims to scale and sustain public goods on Ethereum until it becomes decentralized. Optimism Collective, a new DAO, was recently created to fund public goods and govern the protocol.
