ethereum-consensus
A library for interacting with ethereum consensus objects.
🚧 WARNING 🚧
This implementation has not been audited for security and is primarily intended for R&D use cases.
If you need a battle-tested implementation (e.g. for consensus-critical work), refer to the Lighthouse implementation.
Notes
This crate exposes a series of modules implementing the ethereum consensus specs.
There are a number of top-level modules exposing a variety of supporting types, utilities, etc.
And then a module to drive any state transition in state_transition.
Specialized logic for each fork can be found in the module with the same name as the fork, e.g. bellatrix.
Each fork supports a compile-time "preset", with two common presets mainnet and minimal provided as a convenience.
These modules can be found under each fork module in the presets module.
The generic types are exposed but most users will want to access each fork's logic via one of the presets. See Examples for further details.
An important thing to note is that the state_transition module of each fork (after the phase0 fork) is generated
by a code-generation utility in this crate called gen-spec. This utility specializes each fork based on the prior
Rust module as an input. See the README for that binary to learn further details about operating this utility. The
generated files are checked in so you should not need to use this binary under
most circumstances.
Examples
Refer to the code in examples for the suggested way to use this crate as a user. The intermediate types are laid out
so that you can define your own customizations but you can likely use the defaults.
