Blockchain is a digital ledger that’s used for storing data on several servers across the world in a decentralized, trustless and transparent manner. It represents a paradigm shift on how data is created, stored and shared.
Blockchain technology has grown to become one of the most innovative technological concepts in the world. However, there’s still a significant need for understanding and knowledge on the matter.
In this guide, we’ll share some of the best online courses for learning about blockchain technology and the companies already using it.
Blockchain involves a sequence of multiple blocks joined together in a chain. The first step is to understand what blocks in the blockchain entail. The “blocks” on the blockchain are usually made of digital pieces of information. They include:
The reality for blockchain is much more complicated than just storing the details of a single transaction. A block on theblockchain, for example, can store up to 1 MB of data. Depending on the size of the data, this block can store multiple data amounts at once.
You might be wondering how a blockchain course could be beneficial to you. There are many reasons why you should look into the Distributed Ledger Technology or DLT is an electronic system or database for recording information that is not run by one... More and understand it. They include the following:
The Blockchain Developer Course on Coursera is offered by the State University of New York and the University of Buffalo. It is a digital certification program that has been split into four courses. It is taught and overseen by Rina Ramamurthy, a Teaching Professor of Computer Science and Engineering at the University at Buffalo.
The course covers the fundamentals and some advanced concepts in blockchain, including the design and implementation of smart contracts, the basic concepts of blockchain technology, blockchain frameworks, and the various methods of developing decentralized applications (dApps).
Students are expected to have a working knowledge of the basics of blockchain, as well as an understanding of smart contracts and proficiency in at least one high-level programming language. If you’re looking to get into a career in blockchain engineering, this might be an excellent starting point.
The Blockchain For Business certification course is organized by the Linux Foundation. As its name suggests, the course runs through the significance of blockchain technology and its potential to change the business world. You also get a first-hand view of several cross-industry applications and an introduction to Hyperledger projects.
In this course, the instructor teaches on the application of blockchain in the supply chain, technology, enterprise, and business products. This blockchain course covers several essential fixtures of digital technologies as well, and it goes into the various forms of Hyperledger projects and their distinctions.
Like the Blockchain Developer Course, this course offers a bit of rudimentary knowledge on the distributed ledger technology. This includes an introduction to networks, blockchain frameworks, and some of the most essential blockchain tools. All concepts are explained clearly and comprehensively, thus helping the students to understand blockchain and its applications clearly.
The course is perfect for business professionals who are looking for means to incorporate blockchain technology into their businesses and operations. People looking for blockchain jobs will also have a lot to learn from here. However, note that a rudimentary knowledge of computer terminologies, database administration, and computer networking is required.
Blockchain and Bitcoin Fundamentals is another learning material you should check out. This is a top-selling blockchain course on Udemy. It is facilitated by George Levy, a YouTuber and award-winning blockchain speaker. In this course, you will learn the key elements of blockchain technology and how it relates to Bitcoin – the most popular cryptocurrency.
The course is an excellent choice for beginners who are looking to get an encompassing understanding of blockchain technology. This video course will give you a rundown of the fundamentals of Bitcoin’s blockchain and how everything works. Expect to learn about Bitcoin, miners, hash functions, and how block hashes work in a blockchain.
The course also touches on Bitcoin itself, with details such as its mining, how it is expected to evolve, and more. Levy also touches on other important concepts of the blockchain like smart contracts and other digital tokens. If you plan to go into active trading of cryptocurrencies, you might want to check out this course to learn what sets the price of a cryptocurrency like Bitcoin and what In the crypto world; a ‘fork’ is essentially a change in the protocol of a blockchain. Since cryptocurrencies run on... More are and how they work.
The course retails for $94.99.
Also available on Udemy, the Ethereum and Solidity Developer Course is facilitated by Sebastien Arbogast and Said Eloudrhiri. Arbogast is a full-stack developer who has been working in the tech space for over a decade. He and Eloudrhiri– another experienced IT and blockchain dev –co-founded the ChainSkills Initiative, a training institute for blockchain developers.
This developer course takes you through the development of smart contracts with Ethereum and Solidity.
This course runs you through the basics of a blockchain and how it works. But, it goes beyond that. With real-world examples, participants would learn blockchain development in three separate platforms.
Students would also learn how to develop and deploy distributed applications on various Ethereum projects like the private chain, testrpc, and the mainnet. The course is ideal for students who want to build a career in blockchain development. The course is very theoretical in a non-boring way, and it teaches you how to grow from a rookie developer to the big leagues.
At the end of this course, you’ll have a full understanding of blockchain and how to work through making your own dApp. This course requires students to have substantial experience in frontend or backend software development prior. Knowledge in blockchain development is not a prerequisite.
The course goes for $149.99.
Blockchain and FinTech: Basics, Applications, and Limitations is a learning material offered by the University of Hong Kong on edX. The University of Hong Kong is one of the leading universities in the world, and one of the prominent institutions that offer blockchain courses.

There’s been a lot of talk concerning blockchain being no more than a passing fad that will eventually fade out. This couldn’t be farther from the truth.
Unlike a lot of overly hyped concepts, blockchain has proven to have real value to companies and countries already. The technology is being tested across multiple companies, industries, and regions around the world.
In 2016, Capital market firms spent over $280 million on blockchain, while about 90 % of banks in Europe and North America were also looking into the potential of using the technology. In the same year, blockchain startups generated $1.4 billion in revenues. And that’s just the beginning.
Over the years, several notable companies have come to find that they can effectively optimize their operations with blockchain. Some of these firms include:
The Barclays Bank is one of the largest in the U.K. They’re using the technology to streamline fund transfers and improve their Know-Your-Customer Once you've bought or received bitcoins; you now need to keep them as safe as possible. This guide will provide... More processes. Barclays has filed patents against these two features, showing the bank’s readiness to apply this technology more comprehensively in the future.
