Even though I knew it, I never thought about learning about Blockchain development and writing tutorials about it, until I realized that the time may have come for him to do it. learn the Blockchain.

The development of Blockchain is so much in the spotlight that finance, real estate, health and other industries are keen to learn more about Blockchains and adopt them.

Venture capitalists are currently spending a lot of money on blockchain-based companies, which means there's no better time to learn about Blockchain than this year, and that no better way to start. free online courses.

In this article, I'm going to share 5 free courses on Blockchain technology, which will teach you the basics of Blockchain, its functioning and its disruptive effects. If you want to become a Blockchain developer, these courses will help you get started quickly.

5 Free Classes to Learn BlockChain Development

Here is my list of free courses to learn Blockchain technologies and learn how to use them.

The course is also very convenient because you will learn how to configure the development environment and all prerequisites from a clean Microsoft Windows image, which also makes it easier to follow the course.

After learning the basics, you will create an example of a fully functional application. Your sample application is a distributed application that provides a secure and trusted product lifecycle track for food lots, using blockchain technology.

Once this course is complete, you should be able to create your own blockchain and distributed application contracts with a functional development environment that will make you productive for years to come.

2. Theory of blockchain 101
This is an excellent introductory course at Blockchain. Anyone who wants to know more about blockchain technology can participate for free.

In this course, you will discover blockchain technology (including extraction, consensus algorithms, smart properties, and smart contracts).

4. Ethereum for beginners: create a Hello World Blockchain app
This is a good practical course to start your adventure with Ethereum Blockchain Development, where you will learn how to create a Hello World Blockchain application in no time.

This course is designed for programmers starting with Ethereum Blockchain Development and wishing to test their skills with a basic hands-on project before continuing with more advanced Ethereum development courses covering even more areas.

In fact, this course is an example of their more complete course Ethereum Developer Masterclass: Building Concrete Projects, who teaches Ethereum development in more detail.

If you are more interested in developing with the Etherium network, you can also take a look at this course.

5. Introduction to crypto-currencies and blockchain
This course is more interesting for anyone who is excited about the name of BitCoin and other crypto-currencies. Well, there is nothing wrong with that. Most of us know Blockchain only because of these crypto – currencies and their phenomenal rise.

That's all about some of the free courses to learn Blockchain technology. As I said, the development of the Blockchain is the subject of much attention because of its disruptive potential.

This does not yet generate a lot of jobs but you can stay ahead by learning Blockchain right now.

Besides programmers and developers, these courses are also great for anyone who wants to know what a BlockChain is and how it works, for example. BA / PM and QA.
