Top 5 Blockchain Programming Languages in 2023
Blockchain technology is spreading like fire across industries and businesses. It is currently used in digital voting, medical recordkeeping, decentralized finance, gaming, capital markets, supply chain management, etc. More and more businesses and individual users want to take advantage of blockchain to increase transparency, security, and communication. With so many potential applications of this sophisticated technology, the demand for blockchain development language skills and knowledge has been increasing. This article provides some background knowledge about blockchain programming languages, which can be helpful to both developers and businesses seeking to incorporate blockchain into their work.
Blockchain Market Overview
Blockchain is a complex system of nodes initially designed to store financial data but technically able to hold everything of value. It is an open, decentralized system that allows recording transactions between parties and across multiple devices. Its main advantages include transparency, security, and reliability, as it’s technically impossible to alter the data in the blocks without other users noticing it.
If you are confused, don’t worry. Here’s an example of Bitcoin transactions that will help you understand this technology better. When a user purchases a Bitcoin, the system creates a block representing this transaction and containing information about the time, date, and amount of money. The block is then sent to every node in the blockchain so that all users can see it. After the nodes validate the transaction, it is complete and reflected across all devices. In this way, the transaction becomes an inseparable part of the existing blockchain and ensures the user’s ownership of the Bitcoin. It is essential to understand that the blockchain is not limited to cryptocurrencies and can be used to track anything.
The nature of blockchain technology makes it extremely attractive for different industries, businesses, and individual users. It offers a secure and permanent record of all transactions and ensures an unprecedented level of data ownership. It helps reduce the risks of fraud and security breaches in the financial industry and enable effective monitoring and auditing. It is also associated with increased trust, cost-effectiveness, speed, and immutability, which explains the growing popularity of blockchain development services.
Current and potential applications of blockchain technology are endless because every industry has some information that people want to exchange securely. The following list contains the examples of the spheres in which blockchain has been widely used:
- Decentralized finance (DeFi)
- Digital IDs
- Sharing of medical data
- Supply chain management
- Electronic voting
- Real estate
- Cloud storage
- Asset tokenization
For instance, in the supply chain, blockchain’s unprecedented degree of connectivity helps manage and track millions of products and shipping containers across the globe. Given the fast development of trade, blockchain is extremely valuable for facilitating data transfer among suppliers, manufacturers, shippers, logistic companies, customers, and other stakeholders. Thus, no matter what interests you have or what business goals you pursue, knowledge of programming languages required for blockchain is crucial for designing efficient blockchain-based systems.
Best Programming Languages for Blockchain Development
Since you already know the processes underpinning blockchain’s work, it’s time to discuss the programming languages used for blockchain. These programming languages are very similar to those employed in non-blockchain programs. The only difference is that they presuppose specific methods needed for blockchain creation. Another thing to remember is that the usual programming languages can also be employed to build blockchain systems. So, what are the top five blockchain programming languages?
Top 1. Solidity
- Support of inheritance features in constructions
- Support of hierarchical imaging
- The use of member variables in classes and objects
- The use of ABI
Top 2. C++
This programming language is one of the oldest and most widely used ones. It has had an immense effect on the software industry for the past decade. This medium-complexity programming language is efficient and universal, which explains why many system drivers, operating systems, browsers, etc., use it as their primary language. The following features make C++ suitable for blockchain development:
- Data hiding
- Multi-threading features
- Efficient memory control
C++ is a preferred tool for blockchain development because it boasts high speed and object-oriented characteristics and has multiple platforms. Other features making C++ stand out include high computational performance, transparency, customization, and the use of the Standard Template Library (STL). These features simplify blockchain creation, allowing developers to connect data and functions in modules, just like blockchain uses cryptographic chains to connect the blocks. The fact that most outstanding blockchain platforms such as Ripple, EOS, Stellar, Monero, and Blockchain all use C++ demonstrates its efficiency and reliability.
There are some drawbacks of C++ that should be mentioned:
- This solution may be too complex for low-skilled developers
- Its code may be redundant.
- There is no garbage collection feature in C++
However, these limitations are minor and do not outweigh all the advantages of this programming language.

Top 3. Rust
This newbie is less famous than Simplicity or C++, but it has been widely applied to build secure, innovative, and immutable blockchain solutions. Its most notable advantages for developers include the following:
- Clear development guidelines
- Zero-cost abstractions
- Memory efficiency
- Self-upgradability function due to the use of WASM
- Concurrency-based opportunities
- Management of mutable states
Developers having skills in C++ use find it easy to learn Rust because these programming languages have similar syntax. However, this similarity may also become a challenge if developers fail to recognize the unique characteristics of Rust.
Top 4. Go (Golang)
Go, also referred to as Golang, is another programming language used to create blockchain systems. It is similar to C in synthesis, but it also has garbage collection, memory safety, and structural typing features. Let’s list some of the most notable features and advantages of this language:
- Concurrency features
- Readability and usability
- High-speed performance
- Easy to maintain
- Suitable for high-performing programs
The Go community currently includes more than 800,000 developers, which means that one can always get technical support and guidance online.
Top 5. Python
According to the TIOBE Index and PYPL Index, Python is considered the best programming language for blockchain, along with several other languages mentioned in this article. Its open-source support means that anyone can take advantage of multiple tools, libraries, and frameworks, thus reducing development time. Python is very easy to learn, which makes it a common entry point into the blockchain development sphere. Its universal nature allows using it for network servers, desktop apps, machine learning, and, more importantly, blockchain. The following advantages make Python a preferred choice for many blockchain developers working on diverse projects, from financial software development to gaming:

Python is used in Neo, Ethereum, and smart contracts for Hyperledger, and its simplicity and efficiency will likely expand its application further in the nearest future.
More Programming Languages to Consider
Rholang is less popular than other programming languages, but it can serve developers working with smart contracts well. Unlike most of the object-oriented programming languages employed in blockchain, it is based on a functional approach. Rholang allows evaluating the application as a series of functions, which helps developers solve them sequentially.
Vyper is one of the recently created programming languages, which originates from Python. This language is often used as an alternative to Solidity and is commonly applied for the Ethereum Virtual Machine (EVM). Due to the features such as modifiers, infinite loops, and recursive calling, Vyper helps address common security issues. Similar to Rholang, it can be used for the creation of smart contracts.
Security benefits delivered by Vyper can also be found in Scilla. This new programming language reduces safety risks by providing practical verifications for smart contracts. By using Scilla, developers can reduce the incidence of error-prone codes. However, Scilla and Vyper may be difficult to master because their community is smaller than those of the top programming languages.
