This repository contains several Rust crates that implement the different building blocks of an Ethereum node. The high-level structure of the repository is as follows:

crates/
- db/: Strongly typed database bindings to LibMDBX containing read/write access to Ethereum state and historical data (transactions, blocks etc.)
- executor/: Blazing-fast instrumented EVM using revm. Used during consensus, syncing & during transaction simulation / gas estimation.
- interfaces/: Traits containing common abstractions across the components used in the system. For ease of unit testing, each crate importing the interface is recommended to create mock/in-memory implementations of each trait.
- net/
  - p2p: Implements the Ethereum P2P protocol.
  - rpc-api: Traits
    - Supported transports: HTTP, WS, IPC
    - Supported namespaces: eth_, engine_, debug_
  - rpc: Implementation of all ETH JSON RPC traits defined in rpc-api.
  - rpc-types: Types relevant for the RPC endpoints above, grouped by namespace
- primitives/: Commonly used types in Reth.
- stages/: The staged sync pipeline, including implementations of each stage.
- transaction-pool/: An in-memory pending transactions pool.
crate-template: Template crate to use when instantiating new crates under crates/.
bin/: Where all binaries are stored.
examples/: Example usage of the reth stack as a library.
