Peam

Peam is a Lean consensus client written in Rust.

It is built around a small core, fast SSZ and hashing paths, lean storage, and practical multi-client interoperability.

Status

• Alpha software
• Suitable for experimentation, devnets, and benchmarking
• Not intended for production mainnet use yet

Goals

• Small, auditable codebase
• Low-memory operation
• Fast serialization and merkleization paths using peam-ssz
• Straightforward networking and sync behavior
• Clean operational surface for mixed-client devnets

Build

cargo build
cargo test

To build the binary only:

cargo build --release -p peam --bin peam

Contributing

Before opening a PR, please run:

cargo test

If you are changing sync, state transition, or fork choice behavior, it is worth running at least one mixed-client devnet before pushing.
