Go Proof of Work Blockchain

This project implements a simple proof-of-work blockchain in Go. It allows users to create and retrieve blocks in a blockchain through a web server.

Features

• Blockchain Structure: Each block contains an index, timestamp, data, hash, previous hash, difficulty, and nonce.
• Proof of Work: The blockchain uses a proof-of-work mechanism to validate new blocks.
• HTTP API: The application exposes an HTTP API to interact with the blockchain.

Getting Started

Prerequisites

• Go 1.22 or later
• Go modules enabled

Installation

1. Clone the repository:

   git clone https://github.com/pri-3x/Go-POW
   cd go-pow

2. Install dependencies:

   go mod tidy

3. Create a .env file in the root directory and specify the port:

   PORT=8080
   

Running the Application

To start the server, run the following command:

go run .

The server will start on the specified port (default is 8080).

Add a new block

To add a new block to the blockchain, send a POST request to the / endpoint with the desired data in JSON format:

curl -X POST http://localhost:8080 -H "Content-Type: application/json" -d '{"data": 75}'
