Worked on modularizing the caching system in the bluealloy/revm repository by introducing a dedicated Cache struct and embedding it within CacheDB. This refactoring, implemented in Rust, focused on decoupling cache-related fields from CacheDB to enhance modularity, reusability, and maintainability across the codebase. The new architecture simplifies the caching layer, making it easier to test and extend while supporting future enhancements and cross-module reuse. Emphasizing software design and database principles, the changes established a clearer separation of concerns and aligned the caching infrastructure with the project’s goals for scalable development and improved code organization within the data layer.
