📌 Project Overview/n This project is a terminal-based Banking System implemented in C++ using fundamental data structures like Linked Lists and Hash Tables, and inspired by the concept of Blockchains for enhanced transaction security and integrity.

It simulates a secure and transparent banking application where all transactions are stored immutably using a simplified blockchain mechanism. The system supports basic banking operations like account creation, deposit, withdrawal, and transaction history with a tamper-evident ledger.

🛠️ Features 🔐 Account creation with unique hashed IDs

💰 Deposit and withdrawal functionality

📜 Transaction history with timestamp

🔗 Blockchain-inspired chaining of transactions

🧠 Uses Linked Lists to manage transaction records

🧾 Hash Table-based hashing of user data for quick access and uniqueness

🛡️ SHA-256 style hashing for block creation

📉 Data integrity check using previous hashes

💻 Technologies Used Programming Language: C++

Compiler: GCC / g++

Concepts: Data Structures (Linked Lists, Hash Tables), Blockchain, Hashing

Hashing Algorithm: Custom djb2 for hash table indexing, and SHA-inspired string hashing

⚙️ Setup & Run Instructions Clone the repository: git clone https://github.com/your-username/Banking-Blockchain-System.git cd Banking-Blockchain-System Compile the .c program: g++ main.cpp -o cp2.c Run the executable: ./bank.exe
