This is a simple blockchain implementation in Python. It includes functionalities such as adding users, adding transactions, mining blocks, verifying the chain's integrity, exploring the blockchain, and exiting the program through a menu-driven command-line interface (CLI).

• Add User: Add a new user to the blockchain with an initial balance.
• Add Transaction: Perform a transaction between users, transferring tokens from one user to another.
• Mine Block: Validate pending transactions, create a new block, and reward the miner with tokens.
• Verify Chain: Check if the blockchain is valid and has not been tampered with.
• Explore Blockchain: View all blocks in the blockchain and the current pending transactions.
• Exit: Quit the program.

1. Clone the repository to your local machine:

   git clone https://github.com/Vikranth3140/BlockChain.git

2. Navigate to the project directory:

   cd BlockChain

3. Install the requred dependancies:

   pip install -r requirements.txt

4. Run the BlockChain program:

   python main.py

5. Follow the on-screen instructions to interact with the blockchain:

   • Add users with initial balances.
   • Add transactions between users.
   • Mine blocks to validate transactions and earn mining rewards.
   • Verify the integrity of the blockchain.
   • Explore the blockchain to view blocks and transactions.
   • Exit the program.
