The most recommended blockchain programming languages to learn are Solidity, Rust, Go, and JavaScript. Solidity handles smart contracts, Rust and Go suit infrastructure, and JavaScript covers client-side web apps.
For smart contract and DApp development, Solidity is the primary language for Ethereum and compatible chains. JavaScript and TypeScript are necessary for building web applications and interacting with blockchain APIs, often using React.
For protocol-level and infrastructure work, Rust offers strong cryptography performance and security despite a steep learning curve. Go excels at network programming and versatility. C++ is another solid option for infrastructure, while Python works well for scripting and data analysis.

General Purpose Blockchain Development
Rust is valued for its cryptography performance and security. Rust has a steep learning curve, but it is excellent for speed. "Personally, I think Rust for its cryptography performance. But Golang is a bit better when it comes to network programming."
Go (Golang) is suitable for blockchain infrastructure and network programming due to its versatility. "Rust and Go (golang) are general-purpose programming languages, so they're extremely versatile."
C++ is a solid choice for blockchain infrastructure and protocol-level development. "C++ is the most used language among coders."
Smart Contract and DApp Development
Solidity is the primary language for writing smart contracts on Ethereum and other compatible blockchains. "Solidity is the go-to for smart contracts, especially on Ethereum."
JavaScript/TypeScript is essential for client-side development, web applications, and interacting with blockchain APIs. "If your app is a webapp, you're gonna need javascript, probably react."
Other Relevant Languages
Python is a versatile language useful for general blockchain tasks, client-side scripting, and data analysis. "You can use any language you want to connect to a blockchain API, but Python is the best choice."
Java is a common enterprise language that can be used for blockchain projects. "If you would like to use C#, Java, Python, or Go, you can consider NEO. They allow all those programming languages."
Do you have a specific blockchain or type of application in mind?
Bottom line
For blockchain development, Solidity, Rust, Go, and JavaScript are the most recommended programming languages.
FAQ
What language is best for Ethereum smart contracts?
Solidity is the primary language for writing smart contracts on Ethereum and other compatible blockchains.
Is Rust or Go better for blockchain development?
