Optimism Chain

Definition ∞ The Optimism Chain is a Layer 2 scaling solution for Ethereum, designed to boost transaction throughput and lower gas fees. It functions as an Optimistic Rollup, processing transactions off the main Ethereum chain and then submitting compressed data back to it. This method significantly improves efficiency while retaining Ethereum’s security. It aims to make decentralized applications more accessible and cost-effective.
Context ∞ News about the Optimism Chain frequently highlights its contribution to broader Ethereum scaling efforts and the expansion of its ecosystem. Reports often cover new decentralized applications deploying on Optimism, upgrades to its protocol, or comparisons with other Layer 2 solutions. The adoption rate and ongoing security audits of Optimistic Rollups are key discussion points for their long-term viability and impact on the decentralized application landscape.
