If you’re a software developer or programmer, I’m sure you’ve heard of blockchain by now. If you’ve not heard of the blockchain, you must be living in a bubble. In this article, I will talk about the most popular programming language for blockchain development.
Some of the most popular programming language used to developed blockchains are C++, Java, C#, JavaScript, Go, Python, Ruby, and Solidity. Among these languages, solidity is the only new programming language designed to write Ethereum based smart contracts. Other languages are common and popular programming languages.
The following table lists the programming languages several popular blockchain platforms are written in. The table also lists the languages supported by these blockchains to build blockchain applications.
| BLOCKCHAIN | Written In | Language support | Consensus |
| ARK | JavaScript | JavaScript, Go, Python, C#, TypeScript, Kotlin, Ruby, Swift, PHP | DPoS |
| CORDA | Kotlin | Java, Kotlin, | |
| ETHEREUM | Go, C++, Rust | Solidity | PoW/PoS |
| EOS | C++ | WebAssembly, C, C++ | DPoS |
| HYPERLEDGER FABRIC | Go, Java, JavaScript, Python | Go, Java, Kotlin | |
| LISK | JavaScript, Node.js | JavaScript | DPoS |
| NEO | C# | C#, Java, Kotlin, Python | PoS |
| QTUM | C++, Python, TypeScript | C++, Python, Rust, Go, Lua | PoS |
| STRATIS | C++, C# | C# | PoS |
| WAVES | Scala | Scala | DPoS |
C++
C++ is the 4th most popular language among all the languages. There are more blockchain projects developed in C++ than any other language. Some of the popular blockchains developed in C++ are Bitcoin, Ripple, Litecoin, Monero, EOS, Stellar, and QTUM.
C#
C# is the 7th most popular open source programming language developed by Microsoft. There are 5 to 8 million C# and .NET developers worldwide. Popular blockchains that use C# includes Stratis, NEO, and IOTA.
Go
Golang (GO language) is a new language developed by Google and it’s gaining popularity. Some of the popular blockchains developed using GO are Ethereum, Dero, Hyperledger Fabric, and GoChain.
Java
Java is the most popular programming language. Some of the popular blockchains developed using Java are Ethereum, IOTA, NEM, Hyperledger Fabric, and NEO.
Python
Python is the 2nd most popular programming language. Some of the popular blockchains developed using Python are Ethereum, Hyperledger Fabric, Steem, and NEO.
Solidity
Solidity is a new programming language designed to create Ethereum-based smart contracts. The only blockchain developed and supported by Solidity are Ethereum and its forked and inherited projects.
Summary
C#, C++, Java, Python, and Go are the most popular programming languages for blockchain development. If you’re interested in learning blockchain and becoming a blockchain developer, check out How to Become a Blockchain Developer.
