Blockchain Tutorials

This repo contains tutorials, notes and coude about how blockchain works.

It is a copy of an Udemy course which can be found at Link. It was originally made by Stephen Grider and the course is fantastic.

Contents

• Section 1 - What is Blockchain, Solidity etc.
• Section 2 - Solidity and Smart Contracts + a Sample Starting project Inbox

Requirements

Basic understanding of programming concepts and languages, especially Javascript.

Then there are some libraries that we have to install to start working on it:

Mac OS X

1. You will need Homebrew which you can get:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. You will need Xcode and command line tools installed. You will get XCode from the AppStore and command line tools as: Link

3. You will need npm, which you can get from:

# If you do not have node.js
brew install node

If you are struggling check out htis link: Link

To make sure you have Node and NPM installed, run two simple commands to see what version of each is installed:

To see if Node is installed, type node -v in Terminal. This should print the version number so you’ll see something like this v0.10.31. To see if NPM is installed, type npm -v in Terminal. This should print the version number so you’ll see something like this 1.4.27

4. Install solidity compiler solc:

npm install solc

5. Install test framework (Mocha), local test network (Ganache) and Web3, we are going to install a very specific version of web3, whcih follows the one described in the tutorial

npm install --save mocha ganache-cli [email protected]

Contribution

Please feel free to submit a PR improving this tutorial, I have made it myself and I expect there are a lot of mistakes and misunderstandings so every help is very welcome.
