Welcome to an exploration of sruby, a unique and secure subset of classic Ruby tailored for the Blockchain World Computer! In this guide, we’ll take you through how to use sruby for contract transaction scripts, diving deep into its various tools and libraries designed to make your life easier in the blockchain space.

What is sruby?

Sruby stands for Small, Smart, Secure, Safe, Solid, and Sound (S6) Ruby. It is a subset of mruby and classic Ruby, specifically crafted to interface with the blockchain technology, allowing developers to create efficient and lightweight scripts for transactions.

Getting Started with sruby

To harness the power of sruby in blockchain applications, follow these steps:

1. Setting Up Your Environment

• Ensure you have Ruby installed on your machine.
• Install mruby to get access to sruby functionalities.
• Clone the Red Paper repository where sruby is documented.

2. Exploring the Gems

Sruby comes equipped with a variety of gems (libraries) that streamline blockchain development:

• elliptic-lite: Provides elliptic curve cryptography.
• crypto-lite: Secure hash functions and public key signature algorithms.
• digest-lite: For efficient cryptographic hash functions.
• ethlite: A tool for calling Ethereum contracts via JSON-RPC.

3. Writing Your First Script

Write a simple sruby script to interact with the blockchain. For example, a contract transaction script may look like this:

# Load the required library
require 'elliptic-lite'

# Create a new elliptic curve object
curve = Elliptic::Curve.new

# Generate a key pair
private_key, public_key = curve.generate_keypair

# Sign a message
message = "Hello Blockchain!"
signature = curve.sign(message, private_key)

Think of this script like a chef preparing a unique dish. The require ‘elliptic-lite’ is the cookbook, while the ingredients: private key, public key, and the message are all part of your culinary adventure in the blockchain world. The chef uses a special technique (the sign method) to add a flavor which in our case is ‘authentic’ and verifiable signatures!

Troubleshooting Common Issues

As you embark on your sruby journey, here are some troubleshooting tips to keep in mind:

• Issue: Unable to install a gem.
  Fix: Ensure your Ruby environment is properly set up and that you have the necessary privileges to install gems.
• Issue: Script fails to execute.
  Fix: Check for syntax errors in your script. Comments in your code can be immensely helpful to describe parts of the code and debug.
• Issue: Cryptographic operations return unexpected results.
  Fix: Ensure you’re using compatible public/private keys and the correct hashing methods for your operations.
