What is Blockchain?

Blockchain is a kind of distributed ledger technology that offers an optimum level of security for the stored data making it nearly improbable for anyone to hack or cheat the system. Being a form of distributed ledger technology, it has the following characteristics:

  • Each participant of the distributed network has access to the ledger.
  • Data once saved over the network can neither be modified nor reversed, which makes it immutable.
  • Each piece of data in the network gets time stamped.
  • The participants of the network are anonymous as far as the validity of records is concerned.
  • Data gets encrypted.
  • The technology is programmable.

This is a concise definition of blockchain. Let us now focus on the programming languages that are effective for blockchain.

  • It comes with static writing, which suggests the code doesn’t get compiled till it becomes error-free. It saves time and ensures the sleek development of the project.
  1. RUST

Rust could be a multi-paradigm artificial language designed for performance and safety, particularly safe concurrency whereas Rust is syntactically like C++ one issue that it will guarantee is memory safety by employing a borrow checker to validate references.

As per the survey, Rust has been Stack Overflow’s most loved language for consecutive four years. Impressive, isn’t it? This immense quality shows that people who have had the chance to use Rust have fallen soft on with it.

  1. Golang

Go has been designed and developed at Google by Henry M. Robert Griesemer, Rob Pike, and Ken Thompson. The language is very versatile and straightforward to be told, that makes it compatible with Blockchain, Big Data, Machine Learning, etc. Offering high quantifiability and optimum speed performance. Go may be a statically typewritten programing language and prove its value within the following ways:

  • It is syntactically the same as C, which suggests veteran Blockchain developers will simply comprehend the code.
  • It comes with memory safety which suggests the app is safe from software bugs once accessing the memory.
  • Its readability, additionally as usability, is analogous to Python and Java, that ends up in high quantifiability and higher speed performance.
  1. C#

Designed and developed by Microsoft Corporation the C# programing language got free as a substitute for Java. It’s AN ASCII text file, object-oriented programming language. Being the same as Java and C programming language, it gets thought-about as a decent variety for blockchain development. When you select C# programing language for app development, you’re entitled to the subsequent benefits:

  • Being AN ASCII text file language, it proves to be an economical choice.
