Optimism is a Layer 2 scaling solution for Ethereum, addressing its scalability challenges through optimistic rollup technology. It aims for fast, cost-efficient transactions while maintaining Ethereum’s security. The Superchain concept integrates different L2 chains for better user experience. The $OP token is Optimism’s governance token, distributed through airdrops. Optimism’s benefits include scalability, reduced fees, and enhanced security. It uses rollups to process transactions in batches, reducing gas fees. Comparatively, it differs from Arbitrum, Polygon, and zkSync. Optimism is user-friendly, and the $OP token plays a pivotal role in its governance.
