An educational project that simulates a cryptocurrency ecosystem using core Data Structures and Algorithms (DSA) principles. Built from scratch, this project demonstrates blockchain logic, transaction chaining, wallet balance tracking, mining with proof-of-work, and a modern React-based frontend.
This simulation models real-world blockchain components with a focus on learning. It includes:
- A custom blockchain built using Linked Lists
- Transaction Pool implemented via Queues
- Mining with Proof of Work and SHA-256 hashing
- React-based interface for wallet, transaction, and block viewing
To apply foundational DSA and cryptographic techniques to build a realistic, interactive blockchain simulation — serving as a strong learning platform for concepts in fintech, cryptography, and decentralized systems.
