The most substantial part of the people who are interested in innovations, programming, and technologies know that almost every new raising technology brings with it an innovative method of coding. The same is with blockchains. Most of you probably have heard about the unique features of this technology, so it’s clear that you have to know some specific programming tools to manage this system. If you are new in this world and you have decided to learn blockchain programming, you’ll have to begin studying the details of the system.

How does blockchain work?
Blockchain has its chief role, and it is collecting digital data. The uniqueness of this feature is in the method of doing this. This data is being placed in various blocks that are connected, and this is what makes the data constant, cause once your file is chained, it can’t be modified.
The blockchain is the most prominent model for caching permanent data. For making operations in these complicated systems easier, blockchain uses hashes (private keys) and algorithms for their verification. Some of these algorithms may be familiar to you: Proof-of-Work, Proof-of-Stake, and so on. The very first project that applied this technology was Bitcoin.
Blockchain combines 3 things: security, decentralization, and privacy.
Security. Cryptography is what gives the system its protection. It is the process when you can open a message or get your funds solely if you have matching keys.
Decentralization. One of the best features in the system. The plus of decentralization is that there’s no one central controlling institution or man, everyone, who is registered in the network, controls the chain equally.
For registering to Bitcoin’s system, you need to provide some data like name, id, email, etc. But as soon as you're registered this information won’t be available to anyone, you’ll have two keys: public and private. These keys are the only thing you're expected to own for completing transactions, and you’ll be anonymous as long as you don’t make your private key public. And this is what privacy is in the blockchain system.
Here you can find more about blockchains and their operating process.
Programming languages to choose
As the industry has a promising future, this hard-to-learn thing worths the efforts. Remember that this is a long road to pass until you come to success and also remember that there are some essential things you need to read/watch/collect information about before becoming advanced in this sphere. And here is the list of the best programming languages for blockchain.
- JavaScript
This one is the most popular on the Internet. JavaScript is preferred when you need to build a website with an excellent UI. All the leading browsers support this language.
JavaScript allows building an average but tamperproof blockchain, which is unlikely to hack. The only disadvantage of the language is that it doesn’t have a SHA256 hash function.
- C++
The language was developed by Bjarne Stroustrup in 1985 and is the oldest programming language you can apply in the blockchain. C++ is an object-oriented language, which has some advantages for beginners, e.g., it can be reapplied on several platforms.
As the language is practiced in numerous blockchain-related projects, it’s one of the greatest to study for getting into the theme, but again it won’t be easy.
There're some features of the language, which makes it more preferable for blockchain coding: C++ offers a better memory control, which is necessary for the blockchain for being able to make a secure network, which will accomplish transactions and communicate with multiple nodes at a quicker rate.
While working with C++ as a programming language for your blockchain, you'll have an opportunity to do some jobs distinctly, thus improving the production of the complete digital ledger. This's possible because this language is object-oriented, and one of its properties is polymorphism.
C++ is a mature language, which updates regularly and adds features needed in practice like some analytical tools and debuggers.
- Python
Python was created in 1991 by Guido van Rossum, a Dutch programmer. Python has 3 main components: readability, integrity, and minimalism.

This comfortable world of the language is approved by a mass of programmers (and beginners and advanced ones). It seems that this type of uncomplicated language can’t produce something massive, but it’s not true, and Python goes fine for creating permanent and safe ledgers.
The useful feature of the language is that it’s scripted, giving an opportunity of being compiled and uncompiled. It means if you notice a bug, you can simply fix it in your code and reload the app. This is not possible in C++.
- Solidity
One of the involved, high-level languages, which combines JavaScript’s scripts, functions, and C++ classes. Solidity is freshman-friendly and extends some guidance on how to apply its codes. Even though the language isn't difficult, the ones who’ve already discovered some of the ahead programming languages have an advantage.
The creators of Solidity is the Ethereum team, and it employs the language in their system. The language makes Ethereum’s network faster and easy for smart contract generation.
Solidity also is prominent in cases when you need to hold an ICO or create a Dapp.
- GO
GOLang (shortly GO) is a contemporary coding language formally issued in 2012 by Google. This language works in an operating system that indicates its adaptability, notably when it deals with different parts of the blockchain simultaneously. Various famous platforms are starting applying the GO, for instance, the SDK protocol of Ethereum was produced employing this language.
Reasons to learn blockchain programming

The main reason for learning blockchain programming is that it is the future of the Internet. We’re sure that if you are involved in this industry of innovative technologies, this knowledge will be a great advantage.
The second reason is more practical - It’ s profitable. Nowadays, the blockchain programmers’ salary starts from $100000 per year. There's also a part of advanced programmers who earn over $170000. This is also a great reason to think about studying blockchain programming.
Just keep in mind that it’s never too late. Learn something new and become a professional in it. Knowledge about this technology surely will bring you a prosperous future. But remember nothing is that easy. Keep on trying until you grow into a skilled blockchain programmer.
