OP Stack

Definition ∞ The OP Stack is a modular, open-source development framework created by Optimism, designed to facilitate the construction of custom, interoperable layer-two blockchains known as “OP Chains.” This standardized architecture allows developers to launch their own application-specific rollups, inheriting security from Ethereum while offering enhanced scalability and reduced transaction costs. It promotes a future where many specialized chains operate in a cohesive ecosystem. The stack provides a consistent set of tools and components for rollup creation.
Context ∞ The OP Stack represents a significant advancement in Ethereum’s scaling roadmap, enabling a diverse ecosystem of layer-two solutions. News frequently covers new projects and chains building with the OP Stack, indicating a growing trend towards modular blockchain design and a collaborative approach to expanding network capacity.
