Drachma Blockchain

License

Overview

Drachma is a blockchain project written in Rust, designed to prioritize security, modularity, and efficient performance. With features like Blake3 hashing, UTXO-based transaction management, and Merkle tree integration, Drachma lays the groundwork for a lightweight and scalable blockchain system.

Networking will leverage QUIC for efficient and reliable communication between nodes, ensuring low-latency and high-throughput peer-to-peer interactions.

While the blockchain core is still under development, several foundational components are already implemented.

Current Status

Completed

  • Block structure and logic: Define and manage blocks.
  • Transaction models: Create and validate transactions.
  • Merkle tree: Ensure data integrity within blocks.
  • UTXO logic: Manage unspent transaction outputs.
  • Transaction pool (Mempool): Temporarily store unconfirmed transactions.
  • Utility functions: Provide reusable helper methods.

Work in Progress

  • Blockchain core: Building the chain logic and integration with other components.
  • QUIC Networking: Implementing QUIC for peer-to-peer communication.

Features

  • Efficient Hashing: Powered by Blake3 for fast and secure block validation.
  • Modular Design: Clear separation of concerns for maintainability.
  • Merkle Tree Integration: Ensures data integrity for transactions within blocks.
  • UTXO Model: Implements the Unspent Transaction Output model.
  • Transaction Pool: Handles unconfirmed transactions before inclusion in blocks.
  • QUIC Networking: High-performance, secure, and low-latency communication protocol.
