What is Blockchain Coding and Its Different Languages?

What is Blockchain Coding and Its Different Languages

Blockchain technology was made popular after Bitcoin came into existence.

This technology was used to transfer Bitcoin in order to make the transactions as safe and secure as possible.

The blockchain technology has been developing in leaps and bounds and has been used across several industries and projects.

With its rapid adoption it will not be exaggerating even an iota if it is said that the future will be built on this innovative technology.

The blocks here contain digital information and each of them is connected to the previous one using cryptography.

In each of these blocks there are:

  • A cryptographic hash function to link it to the previous block
  • A timestamp
  • A list if the transaction
  • The digital information and
  • A hash for itself.

The blocks are designed in such a way that it is extremely hard, if not impossible or next to it, to change any data recorded in them.

This ensures transparency, trust, and security, all at the same time.

These features make blockchain technology so popular in the field of banking and finance.

Blockchain technology has the potential to reform the tech world by mitigating the common challenges that a lot of industries face.

This will help them to make the most out of some of the best opportunities that they could not avail before.

In addition to that, blockchain technology has also got the ability to overhaul the entire economy whether it is travel, healthcare, education, or the legal domain.

As said earlier, blockchain technology has been popular ever since it was used for Bitcoin but it is between 2017 and 2020 that the demand and use of this technology increased exponentially by about 2000%.

It is now considered to be one of the most valued technologies that an industry can have.

According to a recent statistical report, the net value of the entire blockchain market will be about $20 billion by the end of 2024.

This indicates its dominating presence not only in crypto but in other fields that you could have hardly thought or heard of.

As a result, a lot of companies are hiring blockchain coding and developing professionals and if you are planning to be one of them, you must know about some of the top programming languages that are best suited for it.

However, before you dive straight into programming and coding languages, you should know about one of the most significant aspects of blockchain coding and programming.

It is called a hash and the entire blockchain concept depends on this.

The hash is actually a Digital Signature or a function that takes input in the form of a command string and returns an alphanumeric string of fixed size.

This hash is an irreversible string which means it is quite impossible to figure out the input string once the hash is created.

Moreover, it is also not possible to have two different values with the same hash.

The hashes are designed carefully by the cryptographers and are computed by the library function built in most of the programming languages.

Ideally, a genesis block will have no hash being the first block of the blockchain and does not need to be tied to any block before it.

In this case the hash of the preceding block will be 0. Ideally, the first value of each subsequent block on the chain is the hash value of the parent block.

The specialty about the specific data structure of a blockchain is that any change in the data will change the hash value of several hashes of the following blocks and these will become invalid.

This will result in the failure of the entire blockchain.

Therefore, the primary thing to remember to become a successful blockchain coding expert is to ensure that a block provides security to the blockchain of the highest level.

Now that you know about the basics of blockchain technology and the significance of hash in it, it is good to have a look at some of the most popular languages used for blockchain coding and programming.

Blockchain Coding Languages

Now, you are quite ready to know about the languages.

When it comes to coding this incredibly fascinating blockchain technology, a lot of different languages are used and you can choose one that will offer you an edge. Here they are.

Solidity

Solidity is one of the most popular and fastest-growing programming languages for blockchain and is the first language that you should learn.

It was specially designed to write smart contracts that are compatible with the Ethereum Virtual Machine or EVM.

This language was developed by Ethereum which itself is a distributed computing platform and an operating system based on blockchain technology.

This means that this language is capable of solving several issues that the blockchain developers may face while coding.

Though this language is developed pretty much in the same ECMA Script syntax, it comes with some additional features such as static typing, Variadic return types, and more.

Therefore, this is a very good blockchain coding language to learn and use especially if you are planning to develop blockchain at depth including getting into the ICO or Initial Coin Offerings game and developing dApps.

This programming language is mainly influenced by JavaScript, C++, and Powershell and was developed by Vitalik Buterin who is the architect of Ethereum.

Therefore, quite naturally, this programming language will offer the developers, individual or a firm, with a host of benefits such as precision and accuracy, developer-friendliness, and accessibility to JavaScript infrastructures, different useful tools and debuggers.

C++

C++ is one of the most commonly used and widely known programming languages within the tech world that serves several different purposes including blockchain coding.

The primary reason for this programming language to be so popular for blockchain technology is its multiple abilities such as advanced multi-threading, move semantics, and primitive control.

It also comes with several other useful object-oriented features such as runtime polymorphism, function overloading, and more.

All these diverse OOP features of the C++ programming language allows the blockchain developers to mold functions and data together very easily in one single module.

It is pretty similar to the new blocks being molded with the blockchain using the cryptographic chains or hashes.

Assuming that you do not know, there is one more interesting fact about the C++ programming language.

The C++ is so popular with blockchain because Bitcoin, which is the first crypto coin that implements blockchain technology for the first time for transferring funds, was written in C++ programming language originally.

Several other crypto coins apart from Bitcoin are also developed using the C++ programming language simply due to the reason that it follows the OOP methodology. This includes Litecoin, Stellar, Ripple, and EOS.

This programming language was developed and released in 1985 by Bjarne Stroustrup and is considered to be the best programming language for anything that is related with crypto development, and blockchain is one of them.

Some of the most significant benefits offered by the C++ programming language are efficient CPU management, easy to run parallel and non-parallel threads, better memory control, and code isolation for dissimilar data structures.

Java

Java is a programming language that offers a solid competition to C++ both in terms of its usefulness and popularity.

This programming language can be easily and effectively used in blockchain coding as well because it comes with a lot of APIs or Application Programming Interfaces.

This includes packages, Java classes, interfaces, and more, all of which helps in building apps without requiring a lot of knowledge about the inside implementations of them.

One of the most significant features of Java which is extremely helpful in blockchain is the portability.

You will be able to port Java programs to different platforms due to the WORA or ‘write once, run anywhere’ property.

The good thing about these programs is that they do not need any system-specific architecture to function.

This is because these programs typically use the universal Java Virtual Machine or JVM for performing.

Apart from the portability property of Java there are several other good features that make it one of the best programming languages to use for blockchain coding.

This preferred language for backend development and the official language of Android mobile app development is a derivative of C-syntax.

If you want to use a high-level blockchain development language then Simplicity is the one you should go for. It will help you to create smart contracts on blockchain.

Simplicity, in fact, is considered to be one of the best programming languages to use by both open source developers and professional programmers.

It will remove the complexities involved in the Bitcoin Script because it will hide the logical components that are of a low level from the Bitcoin developers.

In addition to that, this specific programming language will increase the working capacity of the developers.

This will result in a much faster period for development.

This programming language is also attuned to the Elements platform. This is an open source blockchain platform that comes with side chain capabilities.

Therefore, this programming language will be best suited for those blockchain developers who are creating side chains on this platform.

The language comes with several other features and functionalities that allow high level blockchain coding. Launched in November 2017, this programming language works on Haskell-like syntax and is based on Ivy.

This makes it much easier for a developer to create more effective codes.

And, apart from that, the programming language is extremely mathematical, a virtue that makes the code line readable by humans.

It is especially for this particular reason that this programming language is used extensively by the developers to create smart contracts and other blockchain solutions that are compatible with both Bitcoin and Ethereum Virtual Machine.

Rholang

Rholang is another good programming language to use if you want to create smart contracts on the blockchain.

The unique aspect of this programming language is that it follows a more functional approach instead of an object-oriented approach.

This enables it to solve several blockchain issues.

It is also a reason for the preference and popularity of Rholang.

The apps can evaluate the entire program based on a series of functions that helps in solving the puzzles sequentially.

This is another unique feature of this programming language that distinguishes it from other programming languages such as Python and C.

These languages typically use variables instead for storing data and the value of these variables is altered with time as well.

Vyper

Vyper is a new programming language for blockchain that you can use easily and effectively to write smart contracts.

It is derived from Python 3 and therefore its syntax is pretty similar to and a valid Python 3 syntax but it does not come with all the features of Python.

This programming language is also considered to be a worthy substitute of Solidity and therefore it can be used for the Ethereum Virtual Machine like Solidity.

However, there are different control structures in Vyper than Solidity.

This programming language also handles the security issues quite differently.

This is because it does not come with the OOP functionalities of Solidity and other features such as modifiers, infinite loops, and recursive calling that are known to raise security issues.

Blockchain Coding Challenges

There are a few particular challenges that you may come across and need to overcome while blockchain coding which, if undone, will raise its difficulty level. And, in most of the cases, the language selection will be crucial.

Security: This is your primary concern because a blockchain network is expected to be as strong and secure as a fortress.

This is because the code is typically accessible to the public and everyone can view it, and hackers may look for vulnerabilities and bugs in it.

Therefore, be slow and cautious during the coding process.

Resource management: This is another specific concern which you should look into and ensure that the resources available are adequately and immaculately managed.

This will ensure that you keep up with the pace of the network as well as its demands.

Therefore, make sure that you know about the local and remote queries as well as the ways to respond to them.

Performance: It does not need any special mention that a blockchain network should always perform at the highest possible level.

Therefore, make sure that it has all the capabilities to do it and your language type selection will play a significant role in it once again.

It should therefore be extremely versatile so that it can handle things easily and efficiently whether the task is parallelizable or cannot be performed in parallel.

Isolation: All transaction operations in blockchain development should be deterministic.

This means that every hash function should be deterministic so that it produces the same result always and not behave in one way today and in another way tomorrow.

In the same way, the smart contracts should also work the same way always in every machine and not in different ways for different machines.

The only way this can be achieved is by isolating the transactions and smart contracts from the non-deterministic elements.

Therefore, now that you know about the blockchain coding requirements, the languages to use for it, as well as the challenges that may slow you down, you surely are ready to take it head-on as your future professional career.

Conclusion

Only the most commonly used and popular blockchain coding languages are discussed in this article. However, in reality, there are many more such languages that are used. Research, since the possibilities here are as endless as your future.
