Simplified Blockchain

This project is a simplified blockchain implementation designed to demonstrate fundamental blockchain technology concepts including block creation, proof of work (PoW), and a basic peer-to-peer (P2P) network for sharing data and blocks.

Features

Dynamic block creation with proof of work.
Data addition to the blockchain via command-line interface.
Simple P2P communication between network nodes to share data and blocks.

Prerequisites

GoLang 1.18

Installation

Clone the Repository

Open a terminal and run the following command to clone this repository:
```
git clone https://github.com/toufic0710/Bitcoin_go.git
cd Bitcion_go
```
Compile the Project

Compile the project to generate the executable:

go build -o blockchainApp

Usage

Start a Node

To start a blockchain node on your machine, use the following command. Replace <port> with the port you want your node to listen on.

./blockchainApp -port=<port>

Example:

./blockchainApp -port=3000

Connect a Node to Another

To connect a new node to the network, specify the address of an existing node using the -connect option when starting a new node.

./blockchainApp -port=<new_port> -connect=localhost:<existing_port>

Example:

./blockchainApp -port=3001 -connect=localhost:3000

Add Data to the Blockchain

Once the node is started, you can add data to the blockchain using the add command followed by your data.

add <your_data_here>

Mine a New Block

To mine a new block with pending data, use the mine command.

mine

Architecture

The project consists of several main files:

blockchain.go: Contains the blockchain logic, including block creation and mining.
peer.go: Manages P2P communication between nodes.
main.go: The program's entry point, handling the user interface and orchestrating blockchain operations.
proofOfWork.go: Contains the proof of work logic.
