OP Stack: Modular Framework for Building Scalable Ethereum Networks

The Optimism ecosystem has developed OP Stack, an open-source software framework to build Ethereum-compatible blockchain networks. This modular approach separates blockchain functionality into distinct components, allowing developers to focus on network needs rather than building the entire infrastructure from scratch.

OP Stack's main components are Data Availability, Sequencing, Derivation, Execution, and Settlement. These components can be combined as needed, making OP Stack a flexible tool for developing Layer 2 networks.

The relationship between OP Stack and Ethereum is one of compatibility and interconnectivity. OP Stack-based chains can use similar technology standards, facilitating interoperability with other chains in the Optimism ecosystem.
