Kert-One

A simple blockchain implementation built with Python and Flask. Kert-One aims to provide a fundamental understanding of blockchain concepts, including mining, transactions, and node communication, through a straightforward and accessible interface.

🌟 Features

Decentralized Ledger: A secure and immutable chain of blocks.
Proof-of-Work: Implements a basic Proof-of-Work algorithm for mining new blocks.
Transactions: Supports basic currency transfers between wallets.
Wallet Generation: Easily create new cryptographic key pairs for managing funds.
RESTful API: A Flask-based API for interacting with the blockchain.
Network Discovery (Optional): Basic mechanisms for nodes to discover each other.

🚀 Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

Before you begin, ensure you have the following installed:

Python 3.x: (e.g., Python 3.8 or higher recommended)
- You can download it from python.org.
pip: Python’s package installer (usually comes with Python).

Installation

Clone the repository:

git clone [https://github.com/KertCoin/kert-one.git](https://github.com/KertCoin/kert-one.git)
cd kert-one

(Remember to replace https://github.com/KertCoin/kert-one with your actual repository URL!)

Create a virtual environment (recommended):
```
python -m venv venv
```

Activate the virtual environment:

Windows:
```
  .\venv\Scripts\activate
```
macOS/Linux:
```
  source venv/bin/activate
```

Install the required dependencies:
```
pip install -r requirements.txt
```
(Important: Make sure you have a requirements.txt file in your project’s root directory containing Flask, requests, etc. If not, run pip freeze > requirements.txt after installing them manually.)

🏃 How to Run

1. Start the Blockchain Node

Open your terminal or command prompt and navigate to the kert-one project directory.

```bash python Linux.server.Kert-One.py

(Adjust app.py if your main Flask application file has a different name, e.g., Linux.server.Kert-One.py.)

You should see output similar to:

[timestamp] Servidor Flask pronto em: http://127.0.0.1:5000 This indicates your blockchain node is running on http://127.0.0.1:5000.

(Optional) Run the Client/Interface If you have a separate client or graphical interface, open a new terminal window and navigate to the kert-one project directory.

Bash

python Linux-cliente.py (Replace client.py with the actual name of your client script.)

💡 Usage Examples Once your node is running, you can interact with it via its API. Here are some common endpoints you can use with tools like curl or a web browser:

Get the full blockchain:

GET http://127.0.0.1:5000/chain Mine a new block:

GET http://127.0.0.1:5000/mine Add a new transaction:

POST http://127.0.0.1:5000/transactions/new Content-Type: application/json

{ “sender”: “your_wallet_address”, “recipient”: “another_wallet_address”, “amount”: 10 } Get a wallet balance:

GET http://127.0.0.1:5000/balance/ (Replace with an actual wallet ID from your client_wallet.json or logs, e.g., 9fdd8fd19144e68a8e8afb25979b50108e8099e0.)
