BLOCKCHAIN PROGRAMMING LANGUAGE: FIRST PROFESSIONAL GUIDE

Blockchain Programming

Blockchain development is a service requested by lots of companies in the world and is a mastering target for the existing coders who are willing to learn blockchain programming languages. The neverending ideas for the blockchain projects and the inability to implement them in time have even resulted in the downtrend of ICOs, as there were too few projects created in the end. Most of the ideas were not implemented at all.

Naturally, such situation has caused the strong need in education, books, and guides, that could expand the human resources able to work with the distributed ledger technology. That is one of the reasons why we have recently published the top-14 best blockchain & cryptocurrency books, a list of must-read pieces for programmers and even not tech-savvy people. Today, we are presenting a detailed guide with all truth about programming languages and tools so that you could choose which language to learn and use for your blockchain projects.

BEST LANGUAGES FOR BLOCKCHAIN CODING

programming language for blockchain

As the blockchains get smarter and faster, and their Turing-complete scripting languages need to gather more features, the bitcoin blockchain coding language and framework diversity is growing. Some of the blockchain development languages are usual to any coder and use additional modules or frameworks to build apps for blockchain. The others are entirely new purposely created blockchain programming languages, just based on the common languages.

Both these approaches have one thing in common: they have sets of instructions, and they can process specific data used in the blockchain’s core. Below we are presenting the list of the coding languages actively used by the blockchain developers, their application, level of difficulty, pros and cons, as well the ways to learn them.

С++

  • Where is Used

  • Probably, the most used general-purpose programming language for blockchain, and one of the imperative languages for any developer out there, C++ is widely used as a basis for building blockchains themselves, and for creating the out-of-blockchain parts for the software, such as different blockchain interfaces or oracles for smart contracts. It is C++ that is used in the core of the top cryptocurrencies and blockchains: Bitcoin, Ripple, Bitcoin Cash, Litecoin, Monero, Eos, Stellar, etc.

  • Level of Difficulty

  • C++ is considered to be a standard or medium in the level of difficulty among high-level programming languages.

  • Pros and Cons

  • The object-oriented paradigm of this programming language in blockchain significantly decreases the difficulty of building any software, especially using new technologies. However, its substantial history gives its drawbacks: the language needs to be compiled in most cases, which is excellent for the development of the blockchain, but using C++ as the on-blockchain scripting language is not good. The dApps will be heavier, will need much more time (and gas money) to run, and will bring lots of unnecessary, possibly even unused, code into such smart contract.

  • How to Learn

  • Learning C++ is a relatively easy task, considering the number of educational materials over the Internet, but Bjarne Stroustrup’s ‘The C++ Programming Language’ is worth a look as it is considered somewhat the best introduction to programming in general.

JavaScript

blockchain programming language

  • Where is Used

  • JavaScript is mostly used as a frontend language for building web interfaces. However, many developers are using frameworks like Node.JS, Angular or React to build blockchain applications. Lisk project has even created a development kit with tools written on JavaScript for programmers to build blockchains.

  • Level of Difficulty

  • Nowadays, JavaScript is taught in programming schools and online courses as a starting blockchain development language, as it is that easy to master, and doesn’t require any software beyond your text editor and web browser.

  • Pros and Cons

  • Some of the significant advantages of JavaScript are its low entry point, superior scalability and a giant number of modules and frameworks that expand its possibilities. The latter is, at the same time, a significant drawback, because you need to search for additional tools to build blockchain apps, — JavaScript itself will be not enough.

  • How to Learn

  • As one of the easiest to learn programming languages, JavaScript has a huge amount of guides, lessons, and books. You can even join an online gamified platform such as Codecademy to learn it. As an example, see how easy it is to build something using JavaScript in this basic blockchain development tutorial.

Python

  • Where is Used

  • Although Python was created back in 1991, its popularity has been increasing over the past few years, especially among the AI companies. It is also used for building blockchains and writing smart contracts for, let’s say, Hyperledger or NEO, as its easy syntax but sophisticated features allow it to be one of the prominent programming languages used for blockchain.

  • Level of Difficulty

  • Although Python differs from common C-derived languages of semicolons, parentheses, and braces, it is still fairly easy to learn, especially as one of the first programming languages used for blockchain.

  • Pros and Cons

  • The biggest advantage of Python is that it can be used in both compiled form and runtime compilation of sources, which makes it perfect for both base and scripting approaches. There are some applications in logistics and agriculture, where a blockchain is coded using non-compiled Python, and its nature is changed throughout the operation. Just imagine Bitcoin going from SHA-256 to any other hashing algorithm without any reboots, forks or stop of operation! Python-based blockchains do that.

  • How to Learn

Python has one of the largest open source communities, which gives a great advantage to those who want to learn it. Python officially supports Learn Python, the community-administered website which has all the basic information explained and links to more advanced guides.

Go

  • Where is Used

  • Go, or Golang, is a new programming language with blistering success, including in the blockchain applications. Go is another great language for building bespoke blockchains, with an exception that almost everything is already created before you, and you’re welcome to reuse it. Go-Ethereum and Hyperledger Fabric are probably the most used and demonstrative examples of Golang application.

  • Level of Difficulty

  • Golang is considered to be a difficult language to learn, so if you are new to programming, then we recommend switching to it as soon as you master the programming basics with other languages. Moreover, they say that Go is a very comfortable language to code in after you learn it.

  • Pros and Cons

  • The main advantage of Go is that it combines the best features of Python and JavaScript, including syntax and user-friendliness, as well as the efficiency of compiled languages such as C and C++. Golang is scalable, fast, and flexible. But because it’s quite new, it doesn’t have many packages like other more widespread languages and is hard to learn.

  • How to Learn

  • Being a new language, Go doesn't have many detailed guides or books so far, like JavaScript or C++. However, as its usage and community are constantly growing, Golang is gaining more and more blockchain development tutorials and even extensive coding tours.

Solidity

  • Where is Used

  • Enter Solidity, the first and still the most popular programming language in the blockchain. Created by Vitalik Buterin himself, the mastermind behind Ethereum, the Solidity is a language created specifically for writing smart contracts.

  • Level of Difficulty

  • Based on JavaScript, or even considered as a JavaScript framework, Solidity is comparably easy to learn and implement, which contributes to its popularity.

  • Pros and Cons

  • The fact above is the greatest advantage of Solidity, which also pushed the idea of having smart blockchains and smart contracts towards popularity. Just by knowing the blockchain concepts and a few blockchain-related instructions, almost any JavaScript developer can create complex smart contracts right away. This fact also makes it accessible for lots of JavaScript infrastructures, debuggers, code compactors, repositories, etc. However, as the first language for the first smart blockchain, it also has major drawbacks. For example, conventional concepts of date-time and time variables usual for JavaScript are simply inaccessible from Solidity. Solidity and blockchain do not know what time it is and use blockchain height instead.

  • How to Learn

  • Solidity is highly documented and claiming to become the best blockchain programming language. Apart from the very language documentation, greatly describing all features and functions while they’re only being implemented, there are lots of guides that give great insights into Solidity, as well as smart contract development at all. We also recommend checking out the book by Chris Dannen — ‘Introducing Ethereum and Solidity: Foundations of Cryptocurrency and Blockchain Programming for Beginners’ — if you are planning to study this language.

Simplicity

  • Where is Used

  • Simplicity is the newest language for smart contracts and blockchain programming that works with both Bitcoin and Ethereum Virtual Machine. Based on Ivy, an earlier analog, and using Haskell-like syntax, it offers better code and can be compiled into Bitcoin Script or Ethereum opcodes.

  • Level of Difficulty

  • Thanks to the fact that it uses the existing syntax of Haskell, it is somewhat easy to implement for a skilled blockchain development engineer. However, it is purely functional, doesn’t have variable types, function types and inheritance, and has no loops, so coding in Simplicity language for blockchain projects requires some brainwork.

  • Pros and Cons

  • Simplicity is highly mathematical and has lots of low-level functionality that extends its possibilities while saving code lines. Its main advantage is that it makes smart contracts human-readable and is one of the fastest ways to write them.

  • How to Learn

  • The best possibility to check out the basics of Simplicity programming is to read the whitepaper and check out the guides by those who have already been using it.

Java

  • Where is Used

  • One of the oldest, most popular and the most powerful programming languages couldn’t just avoid the fate of becoming one of the top blockchain programming languages. Java is widely used as a great gateline between blockchain and off-chain part of applications, interfaces, and oracles for some smart contracts. Moreover, lots of new blockchains are written in Java, and, finally, the popular NEO blockchain uses Java as one of its scripting languages for smart contracts and dApps.

  • Level of Difficulty

  • Java is a medium-difficult language with C-derived syntax, which has a large set of high-level and low-level functionality to access to the most sophisticated blockchain parts. Java is very powerful and accessible to lots of developers, and almost any modern developer can start developing blockchain apps with blockchain.

  • Pros and Cons

  • The main advantage of Java is that it is independent of the OS and can run on literally any format of computers. It has strong support for OOP, big community, a collection of libraries, and easy memory cleaning. There are, however, some cons such as lower performance compared to C++ or Golang, and the fact that you need a JVM (Java Virtual Machine) to be installed.

  • How to Learn

  • Being one of the oldest and most widespread languages, Java has loads of guides, books, and other educational content, so starting up with Java doesn’t require any effort at all. Development for exact blockchains has its twitches, so one should dig into the corresponding guides, for example, for NEO, Hyperledger, or Corda.

C#

  • Where is Used

  • C# is probably the most popular modern C-derived language, created by Microsoft, initially for its .net framework. Currently, Microsoft has released .net and C# modules for building blockchains, dApps and smart contracts on them. IOTA project is built on C#, for example.

  • Level of Difficulty

  • C# is a medium-difficult language to learn, as it has implementations for almost any platform out there, and code can also be re-used with any application, just like C++, or Java, or JavaScript. Unlike these languages, C# developers try to keep it away from outdated concepts and add lots of modern coding approaches like lambda expression or syntax sugar to make development in C# faster and easier.

  • Pros and Cons

  • The community of C# is huge, so there’s always someone to build a decentralized app using C#. Apart from the possibilities offered to C# by Microsoft’s native blockchain libraries, C# is also supported as a scripting language by the most modern blockchains, such as NEO.

  • How to Learn

  • Learning C# is not a hard task, thanks to lots of effort put by Microsoft into the development of different educational materials, and the overall ease of the language itself. This being said, Microsoft offers probably the best guides into the language.
