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 blockchain tutorials and online courses for learning about the technology, as well as the companies already using it.

The Basics of Blockchain
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:
- Information about transactions, like purchases on an e-commerce store.
- Information about the person who is participating in such a transaction. This data is stored with a “digital signature,” which replaces the person’s name and goes into the block.
- Information that separates a block from others. Each block stores a unique code, known as a “hash,” that distinguishes it from other blocks. These hashes are made with special algorithms, meaning that the hash of a person’s first purchase on the e-commerce website will differ from that of his or her next one.
The reality for blockchain is much more complicated than just storing the details of a single transaction. A block on the Bitcoin blockchain, 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.
Why Should You Learn About Blockchain?
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 and understand it. They include the following:
1. First Mover’s Advantage
- So far, less than 1% of the world is using blockchain technology. This number is small, but it presents a significant opportunity. Given that global internet, penetration has reached 50% of the world’s population, and people are looking to move into the next thing, learning a blockchain course can provide you with the opportunity to move ahead of the curve.
- As long as you can get the right materials, enrol in a course, and understand how the technology works, you can develop with the world and ensure that you don’t get left behind. It’s like getting a job as a software engineer before the internet boom in the 2000s.
2. The Demand for Blockchain Solutions is Surging
- Blockchain is still in its early days, but the demand for the technology is rising. There are significant opportunities waiting for people to join in the market, and the time seems ripe enough for you to get a good job.
- With more companies looking to invest in the technology, blockchain seems to be one area where you can almost guarantee yourself profitable employment. Pays are also enviable, and you get to be a part of a community that is using technology to change the global landscape. Who wouldn’t want that?
3. It’s a New-Age Technology
- Blockchain technology is a concept that can integrate itself into just about every commercial industry. From trading and real estate to supply chain management and even voting, this technology has the potential to revolutionize the world entirely.
- It’s especially prominent now due to the advancement of the Internet-of-Things (IoT) has also led to massive strides in the development of blockchain.
4. Helping Companies to Evolve
- One of the many benefits of blockchain is its ability to improve trust and confidence between parties in a transaction. Since it reduces the value chain, it can significantly refocus individual players and processes.
- Since managers will be hoping to assess their value chain in the future, and the adoption of blockchain will increase, and this could open up new job opportunities in the future.

Why “Blockchain” isn’t just a Buzzword
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:
a. Barclays Bank
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 security processes. Barclays has filed patents against these two features, showing the bank’s readiness to apply this technology more comprehensively in the future.
Walmart is one of the largest e-commerce companies in the world, and it’s been bullish about blockchain for a few years now. The company is using the Hyperledger Fabric platform – a blockchain supply chain technology built by IBM – to optimize their supply chain process. The company also plans to track the foods it gets straight from the farmers and offer customers the opportunity to check the provenance of goods before making purchases.
c. Anheuser Busch InBev
One of the largest brewing companies in the world., Anheuser is also applying blockchain in its supply chain process. The company has partnered with blockchain supply chain firm BanQu to improve the overall transparency of their systems.
Pfizer is another large firm that works with blockchain. The healthcare company’s Clinical Supply Blockchain Working Group (CSBWG) has completed the proof of concept for tracking records and managing the digital inventory of its pharmaceutical products.
MetLife is an insurance giant. The New York-based firm owns LumenLab, a Singaporean incubator that is collaborating with Singapore Press Holdings and NTUC Income to create Lifechain – a platform that wants to automate life insurance claims.
Blockchain technology has grown to become one of the most innovative technological concepts in the world. There’s a lot to take in and we hope that this guide has provided you with the insight and inspiration to continue learning with some blockchain training courses!
