The largest part of the people who are interested in innovations, programming and technologies know that almost every new raising technology brings with it a new 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 in order 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 main 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, which are chained together and this is what makes the data constant, cause once your file is chained it can’t be modified.
The blockchain is the greatest 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.
Privacy. 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 required to own for executing transactions and you’ll stay anonymous as long as you don’t make your private key public. And this's how privacy is kept in the blockchain system.

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.
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 practised in the numerous blockchain-related project 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 was created in 1991 by Guido van Rossum a Dutch programmer. Python has 3 main components: readability, integrity and minimalism.
This easy 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 generate something heavy, but it’s not true and Python works well for creating durable and safe ledgers.
The useful feature of the language is that it’s scripted, so it may be 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++.
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 contracts generation.
Solidity also is prominent in cases when you need to hold an ICO or create a Dapp.
GOLang (shortly GO) is a contemporary coding language formally issued in 2012 by Google. This language works in an operating system, which indicates its adaptability, particularly when it deals with different parts of the blockchain simultaneously. Numerous famous platforms are starting applying the GO, for instance, the SDK protocol of Ethereum is 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 big advantage.
The second reason is more practical - It’ s profitable. Nowadays blockchain programmers’ salary starts from $100000 per year. There's also a part of advanced programmers who earn over $170000. This is also a good 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.
