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

1. 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!)

2. Create a virtual environment (recommended):

   python -m venv venv

3. Activate the virtual environment:

   • Windows:

     .\venv\Scripts\activate

   • macOS/Linux:

     source venv/bin/activate

4. 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.

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](http://127.0.0.1:5000)
This indicates your blockchain node is running on http://127.0.0.1:5000.

2. (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](http://127.0.0.1:5000/chain)
Mine a new block:

GET [http://127.0.0.1:5000/mine](http://127.0.0.1:5000/mine)
Add a new transaction:

POST [http://127.0.0.1:5000/transactions/new](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/](http://127.0.0.1:5000/balance/)<your_wallet_address>
(Replace <your_wallet_address> with an actual wallet ID from your client_wallet.json or logs, e.g., 9fdd8fd19144e68a8e8afb25979b50108e8099e0.)
