Your bed stand is the best place to store your savings.
Strange statement from a company with a background in the financial industry.
But hear us out. It’s very true. In a way. Provided of course that the bed stand in question contains a specific tool often found there. This tool will become the new focal point of saving and storing money: The smartphone.
Since project Libra was revealed by Facebook two weeks ago, it sparked controversial discussions around its potential as an international currency, its presumed economic impact, and its technical implementation. In this article I will try to shed some light on the technical and the economic sides of the project, to see whether Libra has the required momentum to become Facebook ́s next-generation revenue booster and a meaningful (and powerful) currency for the masses.
In this article, I will give you a smart contract tutorial. It will tell you how to quickly write, test and deploy Ethereum smart contracts. My motivation is to help people to make the first steps. There are several good tutorials which helped me to get started. But I missed kind of a “cookbook recipe” for the entire journey, starting with the installation of tools and frameworks and ending with deployment to Ethereum and usage out of an application.
And so, I decided to write down all the steps involved and hope that you will find it helpful!
I’m working on a Mac, but I’ll provide links to the documentation of all tools and frameworks so that you’ll be able to find fitting instructions for your personal environment.
Today we will:
Setup an environment that allows you to write production-ready smart contracts
Write a simple smart contract
Test security and style guide issues with solhint
Write unit tests with a Truffle framework
Deploy the contract on the Rinkeby testnet using MetaMask and Remix
