By Samantha Allen 03 Apr 2020


In our recent overview of the 2020 Linkedin Learning Report, we highlighted the surprising addition of blockchain to the list of top hard skills in 2020. Blockchain not only made the list of top skills for the first time, but came out on top.

So, clearly blockchain is a must-have skill for 2020 and an important technology to learn. Read on to find out what blockchain actually is, what it’s used for, and how to start learning this in-demand skill.

What is Blockchain?

Put simply, blockchain is a revolutionary technology that is becoming extremely popular. A blockchain is a growing list of records (also known as blocks), which are linked using cryptography. Each block contains a timestamp, transaction data, and a link to the previous block, which creates a chain. 

A blockchain is designed to be resistant to modification of data. It’s an “open, distributed ledger that can record transactions between two parties efficiently, in a verified and permanent way”. 

While this technology is already proving popular, blockchain is expected to have a considerable impact on many industries over the next few years.

What is Blockchain used for?

The most common use for blockchain technology is to build cryptocurrencies (cryptocurrencies are a type of digital or virtual money), such as Bitcoin. While blockchain technology can be used for other purposes aside from financial, it lends itself well to being used for electronic transactions involving large amounts of money, because the technology is so resilient and reliable. 

As well as cryptocurrencies and financial services, blockchain technology is used for smart contracts, supply chain logistics and management, insurance and even video games. Over the coming years we’re likely to see blockchain commonly used for a wide range of purposes.

How do I start learning Blockchain?

With the right training, you could be knowledgeable in blockchain within a few days. There are many different training courses available on blockchain technology, but if you’re brand new to blockchain, try the Blockchain on IBM Z course or the Blockchain Architecture course. These blockchain courses each consist of 18 hours of live instructor-led training that can be delivered online (and once the COVID-19 crisis passes, this course can be delivered at your own office or at a choice of several locations all over the UK, Europe and beyond).
