Vienna Ruby & Ruby on Rails Meetup: Ruby/Rails for Cryptocurrencies, Bitcoin and the Blockchain


The resurrected Vienna Ruby & Rails Meetup will focus on cryptocurrencies, Bitcoin and the Blockchain; By looking at the current implementations and projects out there, monero-ruby, bitcoin-ruby, payment processors and other use-cases with Ruby and Rails will be discussed. The meetup will also feature a blockchain beginners introduction for Ruby developers.

Educator: Ralph Pichler

This ticket is for the event on 23. – 26. November 2017.

This 4-day course teaches the basics of smart contract development on the Ethereum platform using Solidity and the Truffle Framework. It covers the full workflow of developing, testing and deploying contracts as well as interacting with them afterwards. In addition you will learn about common contract patterns and potential security issues.

After the course participants can earn our “Smart Contract Developer” certificate (issued on the ethereum blockchain) by solving a number of off-site exercises. This includes a medium-sized contract example and a number of smaller theoretical and practical exercises. If you are a web developer you can also get the “DApp Developer” certificate by submitting an additional exercise using the web3 api.

In this course you will learn

  • How the Ethereum smart contracts platform works
  • How to write and properly test smart contracts
  • How to use the Truffle Development Framework
  • Which standards are out there and how to reuse well-tested code
  • How to deploy contracts and get them verified on block explorers
  • How to interact with contracts from the Javascript side
  • About common contract patterns and when they are appropriate
  • How to avoid common security issues
  • How your UI can work with different Browsers and Wallets
  • How to debug your contracts

Prerequisites: Basic experience in any object-oriented language
