Myth: Minimal Ethereum Beacon Consensus Client

A work-in-progress minimal Ethereum Beacon (consensus layer) client written in Rust.
The goal is to sync with the Ethereum mainnet, validate blocks, and progressively add features — starting with the core.

---

🛠️ Project Goals

• Build a lightweight, modular, and understandable Beacon node.
• Sync from a checkpoint and validate the chain.
• Designed for learning and customization over performance.

✅ Task List / Roadmap

We are progressing in layered steps — from data representation to sync.

✅ Phase 1: SSZ Implementation (Completed)

👉 r_ssz GitHub Repository

⚠️ This is not production-ready. Any help, suggestions, or feedback are gladly encouraged and appreciated!

• Implement SSZ serialization and deserialization
• Derive hash tree root for basic + composite types
• Support for:
  • BitList, BitVector, Vector
  • Option<T>, List<T>, Container , Union
• Test with synthetic and edge-case data
• Compliant with spec hash root calculations

---

🟡 Phase 2: Consensus Types (WIP)

This is a wip phase

• Define all required types from Ethereum Consensus Specs:
  • BeaconBlock
  • BeaconState
  • Attestation, Checkpoint, Validator, etc.
• Derive SSZ and hash_tree_root for each type
• Add unit tests with reference vectors
