Become a Blockchain Developer

01 introduction

Blockchain programming SolutionS

As the world is advancing digitally, many new innovations are coming into the scene. Virtually everything we enjoy online has a programming undertone. Every software development program takes its fundamental backing from a mix of both low-level and high-level languages. Today, we now have distributed ledger technology and blockchain platforms turning things around in our world.

This highlights the need for blockchain programming and the growing demand for developers who understands blockchain coding.  Software development can be created using any of the common blockchain programming languages, all of which have their uniqueness and a list of the current blockchain network they support.

At iMi, we understand how important blockchain programming and its underlying applications are in changing the world. We also understand how difficult it is for anyone willing to become a blockchain programmer to start off. This is why we have the best blockchain tutorials that you can leverage. On this page, we would tell you more about the mystery called the hash of the previous block in the blockchain.

Best Languages Coding List


What’s the best language for blockchain?

Tagging the best programming language to learn for blockchain development depends on a number of factors which usually vary from one blockchain project to another. However, the list below can help us get a good picture for those who want to know what language is blockchain written in. The most common languages for blockchain programming include but are not limited to;

  1. Phyton
  2. C++
  3. Solidity
  4. GoLang
  5. JavaScript, and;
  6. Rust

enterprise blockchain consulting and deployment services

Now let’s take a look at each blockchain programming language in turn; this overview is just to showcase the blockchain project in which each of these blockchain programming languages has been applied before. C++ is renowned for forming a critical part of the Bitcoin Core. Satoshi Nakamoto, the creator of the Bitcoin blockchain must have gotten his hands full on C++.

A popular project written in Rust is the Near Protocol. ZCash is also known to have some libraries in Rust. Solidity is the underlying programming language used to create the Ethereum-based smart contracts and DApps.

GoLang is known to form the building blocks for Ethereum and represents one of the three original implementations of Ethereum. JavaScript was used Hyperledger Fabric, ARK, and LISK among others.

The list of real-world applications of these languages is non-exhaustive. Each project chooses which language it adopts based on the core features the project is billed to have, and a host of other factors.

Blockchain Programming language list

We have seen the most popular blockchain languages being used by developers building blockchain platforms or decentralized applications in general. In programming for blockchain and open-source protocols, the core features of the programming language must be considered, here, we would explore in brief the underlying qualities of these blockchain languages.

Python python

Created in 1991, Python was made for Simplicity and Minimalism. Most notable, we use “white space” to signify code Blocks. Additionally, we can use SHA 256 hash for security. Python is used to create a very important Time-Stamp.

C++ c++

This C++ blockchain language is designed to have flexibility and efficiency while being object-oriented. It can easily be called and reused in other programs. C++ is offering Memory Control, Threading, Move Semantics, Compile Time Polymorphism, Code Isolation, and Maturity.  In case you missed it when we mentioned it earlier and you are wondering, what language is bitcoin written in? You guessed it, the main Bitcoin programming language is C++. This makes the programming language a highly fundamental language in general blockchain development.

Solidity coding

If you have been following, you might have been able to guess the answer to the question, what language is Ethereum written in? And there you have it, Solidity. If you want to learn blockchain development, this is an absolute must. It is used to make Decentralized Applications or starting your own Initial Coin Offering (ICO). Therefore, we use this code to create Smart Contracts on Ethereum.

Javascript java

The core coding Language is Javascript. Used in the WWW for Content Production. To create the Genesis Block (the mother block) we often use Javascript. Furthermore, we add the Blocks and use JS for Validating the Chain with any previousHash.

GoLang go programming language

We also use GO Programming. GoLang is a very popular programming language. This modern type of coding was developed by Google. It is a very robust multi-purpose language. It features maximal flexibility as we use it for multiple parts of block development.

Rust rust programming language

Finally, we do coding in Rust. It is a multi-paradigm system programming language focused on safety. Specially developed for safe cryptocurrency. Based on its syntax, Rust is similar to C++ but is designed to provide better memory safety while maintaining high performance.

What is blockchain programming?

Blockchain programming is the creative act of using codes to build blockchain applications. It involves the use of dedicated programming languages and a good knowledge of cryptography. Blockchain programming is a little more than a decade old but through it, several blockchain solutions have been built with real-world use cases.


Blockchain code example

When you want to learn how to code blockchain, you will need some coding examples to serve as a reference point in your journey. Whether you are new to blockchain or are an advanced professional, a sample blockchain code can show you how simple or complex a piece of code can be.

In reality, however, the concept of blockchain code is quite simple. It can best be envisioned as a distributed database, having a continuously growing list of records. Additionally, the images below represent a simple way to depict what the building block of a blockchain code looks like. We can start by creating a Block Structure that looks like the following:

Block 0

Index: 0
timestamp: 18:15 1/1/2019
data: “block0data”


hash: 0xea35xy…99


previousHash: 0

Block 1

Index: 1
timestamp: 18:17 1/1/2019
data: “block1data”


hash: 0x6f1dyz…dab


previousHash: 0xea35xy..99

Block 2

Index: 2
timestamp: 18:19 1/1/2019
data: “block2data”


hash: 0x97g3zz…47a23


previousHash: 0x6f1dyz…dab

Here is a brief insight into what we have done in this example of a blockchain code. Block 0 got a hash (…99). This hash must be found again in No 1 as “previousHash”. While “hash” in this has the previous hash as from No 2. Most noteworthy, we kept it simple and only included: The index, timestamp, data, hash, and previous hash. The previous block is found again to preserve the integrity of each block. In addition: Once a block and a hash are created, they cannot be changed anymore. This guarantees full transparency & security.

Finally, please always keep in mind that this technology is not just about Bitcoin or any other Cryptocurrency. It can be deployed to overhaul any ecosystem and startups can benefit from its cryptographic features by implementing it in their customized applications.

Coding blockchain the right way

Blockchain technology is undoubtedly one of the major innovative forces in the world right now. So many industries are currently being overhauled through this technology that highlighting them can prove to be a big task. It is worth noting that the blockchain-based application on Android phones, the desktop apps on Mac, and more were all built through blockchain codes.

Blockchain technology is now also being used in all major industries to ensure transparency and integrity in key operations.

At iMi, we can train you to be an expert in blockchain coding, and if you run an organization, we have some of the best-trained blockchain programming experts that can help you design the aforementioned solutions and more. The use cases of blockchain will continue to expand. Give yourself or your organization the competitive edge by exploring blockchain programming and what it can do for you today.
