Generating Randomness in a Deterministic Environment

Term Paper

This project was developed as a term paper for the ZHAW CAS Big Data Analytics, Blockchain, and Distributed Ledger course. It aims to implement a lottery ticket system using an Ethereum Smart Contract to explore methods of generating random numbers in a deterministic environment.

see semesterarbeit.pdf

Key Features

• Implementation of a lottery ticket as an Ethereum Smart Contract.
• Examination of methods for generating random numbers on the blockchain.
• Provision of a web interface for interacting with the Smart Contract.

Architecture Overview

The application comprises three main components:

1. Smart Contract: Developed in Solidity and deployed on the Ethereum blockchain.
2. Web Interface: A React-based application for interacting with the Smart Contract.
3. Blockchain Network: A local Ethereum network provided by Ganache for development and testing purposes.

Prerequisites

• Node.js (Version 14.x or higher)
• npm
• Truffle
• Ganache
• MetaMask

Development

• Compile Smart Contract >> ./cli.sh --build
• Run Smart Contract >> ./cli.sh --run
• Create Term Paper >> ./cli.sh --documentation

Usage

ganache-cli -p 7545 -d

cd smart-contract
truffle compile
truffle migrate --reset

cd ../web/
npm start
