This project implements a basic blockchain and transaction system using FastAPI for the API endpoints. The blockchain supports adding blocks and transactions, and propagates them to known nodes in the network.

• Blockchain: A simple blockchain implementation with genesis block creation, block addition, and chain validation.
• Transactions: Support for creating and adding transactions.
• API Endpoints: FastAPI endpoints for adding transactions and blocks.
• Threaded Propagation: Transactions and blocks are propagated to known nodes in separate threads.
• Ascon Hashing: Utilizes Ascon hash for lightweight and efficient hashing.

1. Clone the repository:

   git clone https://github.com/your-repo/blockchain-project.git
   cd blockchain-project

2. Create a virtual environment:

   python3 -m venv venv
   source venv/bin/activate

3. Install dependencies:

   pip install -r requirements.txt

1. Run the FastAPI server:

   python Node.py

2. Interact with the API:

   • Add a transaction:

     curl -X POST "http://localhost:8000/transaction" -H "Content-Type: application/json" -d '{"data": "some data", "from_account": "account1", "sign": "signature"}'

   • Add a block:

     curl -X POST "http://localhost:8000/block" -H "Content-Type: application/json" -d '{"data": "some data", "prev_hash": "previous hash", "sign": "signature"}'

• Node.py: Main file to run the FastAPI server and handle API endpoints.
• Blockchain.py: Contains the Blockchain class and related methods.
• Client.py: Contains the Client class for creating and sending transactions.
• Transaction.py: Defines the Transaction class.
• Block.py: Defines the Block class.
• configs.py: Configuration file for server settings and initial known nodes.
• requirements.txt: List of dependencies.
