The Beginner’s Guide to Blockchain Programming: How and What to Learn

Guest Post

A blockchain is the state of the art technology that gives young talents a lot of career possibilities. You can earn more than $100,000 a year working as the blockchain developer, but how exactly do you get to this point in your career? The whole industry is relatively new, so you can’t really enrol a blockchain-focused college.

Instead, you need to take a different path and learn the basics of blockchain programming using other resources. But don’t let that discourage you – here is the beginner’s guide to blockchain programming that will show you how and what to learn.

The Blockchain Basics Explained

Before I start talking about the learning sources, I need to make sure that you understand this concept and how it works. By definition, the blockchain is a digital database containing information (such as records of financial transactions) that can be simultaneously used and shared within a large decentralized, publicly accessible network.

The system has several features that make it such a powerful new technology:

  1. Decentralization

There is not a single authority that controls the blockchain. No banks, governments, or any other regulatory institutions. It’s just a decentralized system that enables users to manage and control their transactions single-handedly.

Users love the fact that there is no government surveillance, but the blockchain decentralization is much more than just politics. Since data storage is not centralized, it’s almost impossible to lose or destroy information, while users also enjoy the benefits of data accuracy and immutability.

  1. Distributed ledger

The blockchain creates a distributed ledger of publicly accessible units of information. Blockchain specialists at the agency, who conducted multiple studies about the transparency of the distributed ledger, say that the system allows each user to see every transaction that has ever been completed within the network: “It doesn’t require third-party mediation, which drastically speeds up the transaction process.”

The two-party system is not only faster but also cheaper. Let’s say you want to transfer money abroad or pay something to the supplier. Using blockchain, you don’t have to pay additional currency exchange or transaction fees. In such circumstances, no wonder that online marketplaces such as Open Bazaar are growing steadily – they don’t introduce platform fees, taxes, or restrictions.

  1. Security

I already mentioned that the blockchain data is public, but I must add that it’s also immutable. Once the information block is added to the ledger, no one can change it. Therefore, the blockchain represents a gigantic self-reviewing system that essentially prevents all sorts of manipulation or digital frauds.

At the same time, the odds of system failure are close to nothing. Potential malware attacks cannot focus on a single central point within the blockchain, so they can’t jeopardize individual users or hurt the blockchain architecture. This takes digital safety to the whole new level, making the blockchain a popular choice among developers.

What Is Ethereum?

Now that you’ve scratched the blockchain surface, you should see how to engage in the real-world programming. The easiest way to do so is by learning how to use Ethereum, an open source platform that utilizes blockchain technology to design decentralized tools and apps.

You can consider Ethereum a distributed “world computer” that gathers thousands of nods to enable independent app creation without the third-party interference. Keep in mind, however, that Ethereum is not just a cryptocurrency.

Most people confuse Ethereum for Bitcoin – the latter is only one type of the decentralized app with a purpose to ensure a peer-to-peer electronic cash system. On the other hand, Ethereum is much more comprehensive, which means you can use it to build many other apps as well.

Ethereum is based on a special programming language called Solidity, so you’ll have to perfect this program in order to become a full-time developer. It is, however, similar to well-known programming languages such as C++ and JavaScript. If you know any of these already, learning Solidity will be much easier.

Solidity is designed with a purpose to build smart contracts, i.e. computer protocols that enable users to exchange anything of value without the help from a middleman. In other words, smart contracts can analyze the current conditions in the ledger and automatically validate a transaction if they determine that the conditions are met.

What makes Solidity-based smart contracts so valuable? First of all, they play the role of multi-user accounts and approve transactions only when a majority of network contributors agree with it. Secondly, smart contracts function like software libraries, providing utilities to other contracts. And thirdly, they regulate agreements among users in case of mutual transactions.


6 Solidity Courses to Check Out

After everything you’ve learned so far, it is time to answer the crucial question – how can I learn Solidity programming? I will show you some of the best online studying sources currently available:

  1. Udemy Courses

Udemy is one of the largest blockchain directories that offers dozens of valuable courses. You can find all sorts of topics – from blockchain in general to specific themes like Solidity or Ethereum. You can search for courses in three different categories: New, Top, and Beginner Favorites. This is not the only way to filter your searches since you can also look for courses based on duration or ratings. Udemy helps you to customize searches and find the course that suits your preferences. The cheapest courses will cost you $11.99.

  1. Zastrin

Zastrin teaches you Ethereum blockchain programming through real-world projects. The real value of Zastrin is the fact that it regularly posts course updates, so you can never work with outdated tools and technologies. There are all sorts of blockchain-related materials available on this platform, so you can make a choice based on your current level of knowledge. You can test most courses for free, but you’ll have to pay for the full version.

  1. Coursera

Coursera is yet another vast library of online blockchain tutorials. If you enter “Solidity” in the search box, you will see almost 30 results, including several courses in Spanish and Portuguese. However, there are other categories to explore here, including Blockchain, Smart Contracts, Decentralized Applications, and many more. Coursera learning resources are excellent for beginner-level students.

  1. Crypto Zombies

If you are looking for an alternative blockchain learning method, perhaps you could try Crypto Zombies. It’s an interactive code school that teaches you how to write smart contracts in Solidity through building your own crypto-collectables game.

  1. Block Geeks

Thousands of students use Block Geeks as their blockchain learning platform. It offers an all-encompassing library of guides and articles, but you can also apply for the official training platform starting at $29 a month.

  1. Bit Degree

Bit Degree is offering both the beginner-level and advanced blockchain programming courses. Completing it, you will learn how to create smart contracts in Solidity and all of its basic features. The courses are interactive and mobile-friendly, which is particularly important if you want to study while commuting. Some Bit Degree courses come for free, but the vast majority will cost you over $100.


It’s not easy to learn blockchain coding, but it’s a highly profitable occupation. This post revealed how blockchain works and where to find learning resources, so make sure to use them and master the art of Solidity programming.
