Few Challenges You Might Face While Entering the Blockchain Development World

  1. Resource Management

    In the Blockchain field, it is imperative for builders to ensure that they are familiar with real-time network requirements and well-versed with opportunities to handle queries. This, in turn, can be challenging for them to manage their resources reliably and effectively.

  2. Isolation

    Another problem faced by Blockchain developers is that all the hash functions operate in a deterministic manner. Meaning, they do not act in two various ways depending on the situations. In such a scenario, the development team has to select Isolation mechanism to bring non-deterministic nature into their blockchain solution.

  3. Lower Performance

    Last but not least, Lower performance is also one of the challenges of Blockchain programming that developers often have to face. Especially when choosing the right Blockchain development language. This is due to some of the Blockchain operations are parallelizable, while others are not. Meaning, it becomes necessary for them to bring a language on the table that is versatile in nature.

    Now that you know what Blockchain programming issues you might encounter while heading your journey to Blockchain development, let’s jump to the core part of this article, that is, unveiling of the top Blockchain programming languages.

Programming Languages to Consider for Developing Blockchain Applications



C++ was introduced back in 1985 by Bjarne Stroustrup, is the best programming language for cryptocurrency development. It is the best blockchain development programming language for definitive reasons like its primitive control over memory, advanced multi-threading capabilities, move semantics and core object-oriented features such as runtime polymorphism and function overloading. The object-oriented feature of this blockchain coding language provides developers, the ability to bind the data and the methods intended to manipulate them together, just like how blockchain binds blocks with cryptographic chains.

The language follows OOPs methodology and is highly used for building cryptocurrencies and Blockchain Projects such as Bitcoin, Litecoin, Ripple, Stellar, and EOS. Something that is a direct result of the following set of features and functionalities it provides:

    • Efficient CPU management and memory control,
