Whether you’re looking for blockchain development work or you just want to know more about what goes on behind the scenes, you need to pick the right language for programming your blockchain. The six languages listed below are some of the hottest tools of the trade right now in the world of blockchain development.
C++ is a tried-and-true programming language that has stood the test of time. While it can be used for higher-level tasks, it also allows programmers to get very close to the hardware itself. This has made C++ highly popular for uses such as embedded systems and computer graphics.
Of course, this also means that C++ gives you a lot of power when building the actual blockchain infrastructure. If you want to make your blockchain as efficient and speedy as possible, optimizing the number of transactions per second, then C++ is a natural choice.
While C++ is by no means bad for smart contract work, it’s not automatically suited for doing it either. As a result, blockchain developers have created programming languages such as Simplicity to work on top of languages like C++.
While C++ is more than 30 years old, Simplicity could hardly be newer. The language’s creator, Russell O’Connor, announced its release at a workshop in November 2017.
Simplicity is a higher-level programming language that allows you to write more human-readable smart contracts. The Bitcoin cryptocurrency already has a smart contract language called Bitcoin Script, but it’s fairly low-level and requires an advanced understanding of Bitcoin.
By abstracting many of these low-level concepts from Bitcoin Script, Simplicity makes it faster and easier than ever to write smart contracts.
In particular, Python is excellent at crunching numbers—taking large data sets and cleaning, processing, analyzing, and visualizing them. These skills lend themselves very well to data-driven industries such as finance and the Internet of Things.
Beyond these capabilities, Python is an excellent general-purpose programming language that can be used for both building blockchains and writing smart contracts.
While it has many of the same advantages as languages like Simplicity, Solidity is designed specifically for use with the Ethereum blockchain network. Solidity allows programmers to write higher-level code which is then compiled down into low-level machine language.
RChain is an ongoing development project that’s in the process of building Rholang, a concurrent programming language for smart contracts. Unlike the five languages above, which are object-oriented in design, Rholang is a functional language.
Functional programming is a different way of thinking about programming. Instead of using variables to hold values, and changing these values over the course of the program’s execution, functional programming sees programs as a series of mathematical functions to be evaluated sequentially.
A vocal minority of developers prefer using functional programming languages, such as Lisp and Haskell, due to advantages like elegance and concurrency. Although RChain and Rholang will offer many of the same capabilities as languages such as Simplicity and Solidity, Rholang operates in a specifically functional context. The project caters toward those blockchain developers who prefer to work in a functional programming environment.
After reading about the six languages above, you’re undoubtedly wondering which of them is right for your project. Answering this question starts with understanding what you’re actually trying to do and what networks you’ll be working with.
If you want to implement a new cryptocurrency, you can probably start with Bitcoin and Simplicity. Bitcoin is based on a proof-of-work blockchain, which you could copy and build out using Simplicity. You can also work with the established Ethereum blockchain using Solidity.
