Crypto Voucher Library

Overview

The Crypto Voucher Library is a multi-language implementation designed to simplify the use of cryptocurrency for everyday users. The project is implemented in Elixir, Go, Node.js, PHP, Python, and Ruby, making it accessible to developers working with diverse platforms and tools

Purpose

One of the significant barriers to adopting cryptocurrency is the complexity of managing wallets, securing private keys, and understanding how to use them, This library addresses that challenge by introducing a simple voucher system:

1. For Buyers:

   • A user buys cryptocurrency worth a specific amount (e.g., $10).
   • The system generates a wallet, transfers the cryptocurrency into it, and creates a voucher based on the private key of the wallet!
   • The buyer receives the voucher

2. For Sellers (Merchants):

   • A merchant accepting the voucher can use this library to decode the voucher back into the wallet's private key!
   • The merchant checks the wallet's balance and processes the transaction
   • Once verified, the product or service is provided to the buyer

This system abstracts away the complexity of managing wallets while ensuring security and usability for general users

How It Works

1. Creating a Voucher:

• A user initiates a purchase (e.g., $10 worth of cryptocurrency)
• The system:
  1. Creates a wallet for the user
  2. Transfers the cryptocurrency into the wallet
  3. Encodes the wallet's private key into a voucher (key + code)
• The user receives the voucher, which can be used for transactions

2. Redeeming a Voucher:

• The merchant:
