Project Summary: Masa Blockchain Implementation

Overview

This (PoC) for a blockchain implementation named "Masa Blockchain." It aims to demonstrate the core functionalities of a blockchain, including block creation, consensus mechanisms, and data persistence. The project will eventually be integrated into the Masa Protocol codebase.

Key Features

  1. Consensus Mechanisms: Proof of Work (PoW): Implemented in src/blockchain/pow.go. Proof of Stake (PoS): Implemented in src/blockchain/pos.go. Based on n number of MASA tokens staked?

  2. Block Management: Block creation and validation. Serialization and deserialization of blocks. Adding blocks to the blockchain.

  3. Blockchain Operations: Iterating over the blockchain. Fetching the last block. Updating and maintaining the last hash.

  4. CLI Interface: Adding blocks. Listing all blocks or the last block. Selecting consensus mechanisms via command-line arguments.

  5. Persistence: Data storage using BadgerDB for TXNs. Initialization and management of the blockchain database.

Benefits Modularity: The project is organized into distinct modules for consensus mechanisms, block management, and persistence, making it easy to extend and maintain.

Flexibility: Support both PoW and PoS, allowing for experimentation with different consensus algorithms. CLI Interface: Provides a user-friendly command-line interface for interacting with the blockchain. Persistence: Ensures data durability and integrity using BadgerDB.

Conclusion A Masa Blockchain PoC provides a foundational implementation of blockchain technology, demonstrating key features and benefits. It serves as a robust starting point for further development and integration into larger systems.
