Blockchain has become a buzzword in today’s tech world. This technology has successfully resolved the traditional roadblocks existent in certain industrial domains by decentralizing data and opening up new avenues of security and transparency.
Blockchain records digital information in a manner that the information can be recorded and distributed, but not altered. Hence, Blockchain is used to form immutable ledgers and records or transactions that cannot be hacked, modified, or destroyed. Blockchain applications are employed for demanding tasks like the exchange of cryptocurrencies, the secure sharing of medical data, voting mechanism, NFT marketplaces, making/receiving cross-border payments, monitoring supply chain/logistics, and many more.
However, developing such solutions is not an easy task, and businesses planning to adopt Blockchain systems must be aware of the ins and outs of Blockchain development. One of the crucial considerations for creating Blockchain solutions is the programming language stack chosen for development. And, needless to say, the programming language should be chosen as per the project requirements. This post explores the offerings of the top Blockchain programming languages with examples of use cases. The write-up will provide a clear idea and help you to pick the most suitable language stack for your upcoming Blockchain project.
Blockchain Functioning: In a Nutshell
The Blockchain system comprises a digital ledger of transactions. Each block within the chain contains a certain number of transactions and whenever a new transaction takes place on the blockchain network, the transaction record is added to each participant’s ledger. This decentralized database is called DLT (Distributed Ledger Technology) and is managed by multiple participants.
Top Blockchain Programming Languages
Solidity was created by the Ethereum team in 2014 for writing Ethereum-based smart contracts, to enhance the usability of Blockchain solutions. With Solidity, developers were able to write a high-level code that is smart-contract oriented and that could be translated into the usable lower-level languages prevalent at that time. The language resembles the ECMAScript syntax but contains features such as static typing, variadic return types, and so on. And hence, it is one of the most preferred programming languages used for Blockchain projects and recommended by most Blockchain app developers around the world.
This statically typed Blockchain language offers a stable and flexible coding pattern for smart contracts and provides an accurate as well as a safe medium where different sources can frame smart contracts between parties. Moreover, it is a flexible and user-friendly language that comes with ABI (Application Binary Interface) that provides several type-safe functions. Developers can effortlessly acquire the necessary skills needed to use Solidity, whether they are experienced ones or simply beginners.
Blockchain Project Use Cases: Ethereum, Chainlink, Sushiswap, and Compound Protocol.
This object-oriented language is one of the key Blockchain programming languages. C++ was created to code the decentralized cryptocurrency system and developers employed it to code bitcoins. But today, it suits the purpose of other Blockchain-based projects and has been used for storing transaction information in cryptocurrencies like Ripple’s XRP Ledger, Ethereum’s smart contracts, etc.
C++ is easy to use and flexible; and comes with abilities like advanced multi-threading, primitive control over memory, and an efficient CPU management capability. It enables one to isolate the code for various data structures and allows you to move semantics so that data can be copied effectively. C++ users can control the code as desired – they can choose between providing full access to the code or allowing access to only certain aspects as per the need. With C++, one can easily manipulate blocks and chains, and so, is an ideal pick for scenarios where one needs to fully control their system resources.
Blockchain Project Use Cases: Monero, Ripple, Stellar, EOS, Litecoin.
Python is one of the most popular programming languages used for architecting Blockchain applications, crypto exchange, and smart contracts. It is a robust, versatile, and object-oriented programming language that comes with open-source support and also, several frameworks and libraries such as Numba that accelerate the development without affecting the performance or security. Python dynamically supports OOP, and hence, facilitates crafting solutions in Blockchain as well as in Machine Learning and Artificial Intelligence. Using this language, one can easily detect errors and debug those errors.Python is particularly helpful for newbie developers working on Blockchain projects as this language facilitates building prototypes quickly without having to write lengthy codes and the developers have the option of selecting from a wide range of plugins, libraries, and online resources.
