How to become a Blockchain Developers | Best Free 7 Courses to Learn Blockchain in 2022

 

Along with other tech trends like Artificial Intelligence and Virtual Reality, blockchain has become almost the buzzword in Silicon Valley and beyond. Blockchain is the distributed ledger technology that powers bitcoin and other cryptocurrencies. Now, the Internet of Things is proving its potential in other areas such as supply chains, finance, and entertainment, and is particularly hot with crypto technologies.

 

Big entrepreneurs like IBM and Microsoft are planning to invest in blockchain and incorporate its features and innovations into their businesses. Experts believe that the blockchain will be a determining factor in the future of the Internet and online commerce.

 

As a result, knowledge of blockchain use cases and development can help your business in the long run and in your career as a technologist and software developer. Here's what you need to know about getting started with blockchain development.

 

What is Blockchain?

 

Blockchain is a distributed data store. Unlike traditional repositories that store data on central servers and server clusters, the blockchain creates copies of the ledger and stores it on thousands and millions of computers; These are also called nodes. Once a reasonable number of nodes are registered, they should validate each new registration. Once approved, it is saved on all devices in the registry and propagated in the network of participating nodes.

 

What Does a Blockchain Developer Do?

 

Now that we've got this out of our system, let's take a serious look at what a blockchain developer is up to. To best answer this question, we first need to identify that there are two different types of Blockchain developers; There is Core Blockchain Developer and Blockchain Software Developer. Call them subdivisions of Blockchain development.

 

A Core Blockchain Developer designs the security and architecture of the proposed Blockchain system. In essence, the Core Blockchain Developer lays the foundation on which others will build.

 

Which “others” are we talking about? This, of course, will be Blockchain Software Developers using the core web architecture created by the Developer to build applications, especially the decentralized (dapps) and web variants.

 

Perhaps there are situations where the same person fulfills both roles, most likely where the business is small and people traditionally wear more than one hat. Whatever the case may be, the day-to-day responsibilities and roles of the Blockchain developer are:

 

  • Design blockchain protocols
  • Design the network architecture that can be used to centralize or distribute data
  • Backend development based on blockchain protocols
  • Developing front-end designs based on customer requirements
  • Development and monitoring of smart contracts

 

Who Hires Blockchain Developers?

 

Beyond the world of cryptocurrencies, blockchain promises a highly significant career in many industries. You can find many examples of this.

 

  • In the music industry, blockchains open up new possibilities by establishing direct relationships between artists and fans and putting art back in the hands of those who created it.
  • In production and distribution, blockchain brings greater transparency to the supply chain and makes it easier to audit and verify the location of goods and the actual cost of production.
  • In the gaming industry, blockchain can support virtual economies that have emerged over the past decade for players to gain greater control of their assets and the games within. It also makes it easier for indie developers to compete in an increasingly polarized and larger player-controlled environment.
  • A number of organizations that handle sensitive information, such as military and healthcare organizations, are considering blockchain as the key to protecting the integrity of their information and infrastructure.
  • These are some of the areas you can expect to find a well-paying job if you have solid blockchain development knowledge. Blockchain is slowly spreading to other fields and industries. Wall Street is investing in blockchain, which is creating a large number of new jobs.

 

Free Online Courses to Learn BlockChain Development in 2022

 

1. Blockchain Theory 101

 

This is a great introductory course on Blockchain and anyone who wants to learn about blockchain technology can join this course for free. In this course, you will learn about blockchain technology (including mining, consensus algorithms, smart property, and smart contracts).

Instructor Melanie Swan is also the author of a published book Blockchain: Blueprint for a New Economy, which means she has a good knowledge of Blockchain.

The current state of blockchain technology, potential applications in Financial Services, Logistics, Health, Energy, and IoT, and next steps regarding its deployment in your organization.

 

 

2. Enterprise Blockchain Fundamentals

It's free though, so you have nothing to lose but you will learn an in-demand skill to grow your career.

 

3. Blockchain Fundamentals

 

This is a great course from Pluralsight to learn about Blockchain Fundamentals and Smart contract development

In this course, you will first learn about the Ethereum blockchain, smart contract development, and how to create custom blockchains.

Also, the course is very hands-on as you will learn how to set up the development environment and all prerequisites from a clean Microsoft Windows image that makes the course easy to follow.

 

After learning the basics, you will create a fully functional sample application. Your example application is a distributed application that provides a safe and reliable product lifecycle trace for food groups using blockchain technology.

After completing this course, you should be able to create your own blockchain contracts and distributed applications with a functional development environment that will keep you productive for years to come.

 

4. Blockchain Fundamentals by Coursera

 

This is one of the most popular courses on Coursera to learn Blockchain fundamentals. It is actually the first course of the Blockchain specialization that provides a broad overview of the fundamental concepts of blockchain technology.

In this free Blockchain course offered by the University of Buffalo and the State University of New York, you will learn about the decentralized peer-to-peer network, an immutable distributed ledger, and the trust model that defines a blockchain.

This course will teach you the basic components of a blockchain (transaction, block, block header, and chain), its transactions (verification, verification, and consensus model), basic algorithms, and foundations of trust (hard fork and soft fork).

 

By the way, if you find Coursera courses useful as they are created by well-known companies like Google, IBM, Amazon, and the best universities in the world, I recommend you join Coursera Plus, Coursera's annual subscription plan.
