RustyChain

RustyChain is a minimal Proof-of-Work (PoW) blockchain project written in Rust.
It demonstrates the basics of decentralized consensus, cryptographic hashing,
and simple peer-to-peer networking using libp2p.

Features

• Proof-of-Work: Uses SHA-2 hashing for mining with a configurable difficulty target.
• P2P Networking: Gossips new blocks to peers, ensuring the network converges on a single chain.
• Longest Chain Rule: If a longer (valid) chain is found, the node will switch to it.

Basic Commands

• Build the project

  make build

• Run the project

  make run

• Lint the code

  make lint

• Run unit tests

  make unit_test

• Pre-commit check (lint + unit tests)

  make pre_commit

Roadmap Checklist

• Implement Block & Blockchain structures
• Implement static difficulty mining (PoW)
• Add basic networking with libp2p
• Automate difficulty adjustment
• Expand test coverage (integration tests, property-based tests)
• Set up a continuous integration (CI) pipeline
