Kona is designed as a modular, library-first OP Stack implementation in Rust. This design philosophy allows developers to integrate Kona components into their applications and build custom solutions on top of the OP Stack.

​
Library Structure

Kona is organized as a collection of focused crates that can be used independently or together:
  • Protocol Libraries: Core protocol logic and data structures
  • Node Components: Modular node architecture for building custom rollup nodes
  • Proof System: Fault proof generation and verification
  • Utilities: Common utilities and helper functions

​
Key Benefits

  • Modularity: Use only the components you need
  • Performance: Rust’s zero-cost abstractions and memory safety
  • Extensibility: Easy to extend and customize for specific use cases
  • Reliability: Strong typing and comprehensive testing

​
Getting Started

To use Kona as a library, add the relevant crates to your Cargo.toml: 
[dependencies]
kona-derive = "0.1"
kona-protocol = "0.1"
kona-node = "0.1"
