What is Crypto Programming: features and perspectives

30 November 2021, Tuesday By Priyanka Boruah

Development is a promising and monetary direction. This area attracts more and more people, even those who used to be far from computers in general, not to mention some advanced technologies. Only the lazy have not heard about cryptocurrencies either, because bitcoins have already made a lot of noise.

And these two things at the junction form our future, offering an even more specific, in-demand and interesting profession to everyone.

Crypto programming

What is blockchain and cryptocurrency?

In general terms, a blockchain is the technology with a huge database that contains a ledger containing information about all transactions. As in a bank, in the blockchain network, the ledger also contains information about the state of the currency. But unlike a bank, in a blockchain network, each user has a copy of the ledger and with it the ability to check each other's accounts. 

Blockchain eliminates an important problem with centralized systems - distrust. All data is decentralized, so no one can control the information on the blockchain network. Every user has an exact copy of the system, and the risk of losing content is dramatically reduced. An infinitely reliable exchanger for data and money.

Cryptocurrencies are alternatives to real currencies, but in digital form and with a number of specific rules for storage, production and exchange. They have their own rate, their commissions, their own conditions for deposits, but they do not depend on banks. 

Where is blockchain used?

  1. When exchanging cryptocurrencies, of course. Decentralized financial systems have spawned thousands of digital currencies.
  2. For the safe storage and transmission of medical information.
  3. NFT markets of all kinds that sell non-replaceable tokens that validate digital art.
  4. Systems for tracking the order of payment of royalties for listening to music from independent musicians.
  5. To make payments between countries.
  6. Voting or auction systems.
  7. Win-win lotteries, where the balance accumulated in excess of what was invested by the auction participants appears as the winnings (see the book "How to DeFi" for more details). 

Blockchain is not just about bitcoins. It is a mechanism that captures more and more areas of life where safety and reliability are required. 


Crypto-programming concept

In short, crypto programming is software development using blockchain technologies, as well as combining them with more familiar frameworks and languages ​​like React and C++.

Development in the field of cryptocurrencies and blockchain is becoming more and more in demand. This is a job with huge salaries, endless vacancies and unlimited potential for the future. It is the great reserve for the future that drives these technologies far ahead. 

The point is that cryptocurrencies and blockchain will form the basis of the economy of the future, where decentralized financial systems will rule the ball. And the blockchain technology itself turned out to be universal enough to be useful not only in strictly financial matters (investments, auctions, commercial relations, etc.), but also in other areas of human activity. 


Once you get involved in crypto-programming, you will make programs like other developers, but under the hood your projects will have code that is directly related to the most advanced technologies in existence. 

Who is a blockchain developer?

This is a person who is not just close to computers and knows how to layout a page, but a developer who is well acquainted with decentralized finance technologies. At best, one who has experience working with the backend component of programs, and at worst, at least one who understands how to write program code in principle.

Such a developer is engaged in creating backend code for decentralized applications called Dapps. They usually exist on the Ethereum network and are nothing more than smart contracts. 

A blockchain developer must be able to write either in specialized languages ​​created for working with cryptocurrencies, or in familiar languages ​​used to create blockchain applications (including C++ and Java).

What is Ethereum? 

Ethereum is a whole blockchain environment that allows anyone to run programs in a trusted environment supported by smart contracts. 

Unlike Bitcoin, the Ethereum platform allows you to interact not only with cryptocurrencies, but also with other data. 

The corresponding programs run in an environment called EVM (Epehreum Virtual Machine). It allows you to transform code written by people into a character set that is digestible for the blockchain and maintains smart contracts created to perform certain tasks within the blockchain in working order. It also uses its own currency called Ether. 

What is Ethereum

This is the largest system of its kind and at the same time the most demanded. In most cases, they are looking for crypto programmers to create software that will be implemented in Ethereum. 

What about smart contracts?

This is code that runs in the EVM environment and is capable of processing data, Ether, or some kind of logic transferred to it. For smart contracts, functions are written that allow you to manipulate the information passed to it. You can share data with other smart contracts or, based on the information received, transfer Ether between contract users. 

A smart contract allows you to exclude a third party from any transaction. The program code will be responsible for justice: open, incorruptible and working correctly. 

Crypto programmers are involved in the creation of smart contracts, allowing the inhabitants of the blockchain network to make transactions related to Ether.

What languages ​​and libraries are used in crypto programming

To create smart contracts and other components of the cryptocurrency network, both traditional general-purpose languages ​​and new ones created specifically for working with Ethereum or its analogues are used. 

The four most popular are:

  • Solidity. It is a leader in the field. The first language worth learning to start creating Dapps and smart contracts. The language is based on jаvascript and C++ syntax. It has strong typing and a fairly low barrier to entry for beginners.
  • Java. A powerful platform that has proven itself in dozens of development areas, including software development for mobile operating systems. It is in demand in the blockchain environment due to its strict adherence to the principles of OOP and the abundance of libraries required when working with cryptocurrencies.
  • Vyper. Safe and functional programming language with syntax borrowed from Python. Focused on working with EVM and creating smart contracts. 
  • Python. Python itself could not pass by this top either. One of the most universal and ubiquitous languages ​​has found its place in the blockchain space. Used to build Steem, Hyperledger Fabric and NEO platforms. 

How to Start a Career in Crypto Programming?

The threshold for entering the profession is not too high. Due to the high demand, the requirements are not very strict, but just wanting is not enough. It is necessary to gain basic knowledge and delve into the study of blockchain programming languages. 

What do you need to learn and what do you need to know?

For a start, it's worth reading about the blockchain in general. We need to understand how the whole system works in general terms. Familiarity with the technical details of the implementation is optional, at least in the early stages. 

After that, you need to decide on the language. Solidity is recommended for beginners as it is easier to understand. The next step should be either a deep study of the documentation with constant independent practice, or attending appropriate courses. 


In terms of equipment, you don't need anything. It is enough to open a web IDE called Remix and write your first smart contract according to the instructions on the official Solidity website. 

After Solidity, you will have to learn the frameworks used: Truffle to simplify the creation of smart contracts, Ganeche for testing software in a virtual blockchain network, Web3.js to connect the backend component of your brainchild with a front-end (this can be React or Vue).

On the courses, you will be kicked out in all aspects at once. Many active Solidity developers have entered the profession through courses. The average training time does not take even six months.

Learning resources and useful links

You can study at the same sites where they teach to write programs based on React and other more familiar technologies. True, crypto-programming is not yet particularly popular on Indian platforms in the spirit of Udemy or Coursera, but there are suitable courses on foreign resources.

  • Coursera is a huge database of educational materials and courses. If you wish, you can complain about a hard life and request a discount on tuition up to 100%. 
  • Udemy is home to some cool Solidity courses. Often sells educational materials at up to 90% off. You can grab a massive lecture list for the price of a cup of coffee. Here's one of the courses that current Solidity developers praise - link.
  • is a site that explains what Ethereum is and how to work with it.
  • Official Solidity Documentation. Your handbook in case you really want to master the language and move into the camp of crypto programmers. 
  • I also recommend the book How to DeFi, which details decentralized finance. After reading it, you can easily turn into a crypto investor.

Prospects of the direction

Companies are taking cryptocoders with their feet and hands, even if they have just begun to study the blockchain and related technologies. 

The demand is so high that even the developers who just opened the Solidity docs are hiring them. If you have written at least one program in your life and are now reading this article, then you can already look for a job. And it's not a joke. 

The demand for such developers has grown by 517% between 2019 and 2020, and this figure is growing. The money is also crazy there - senior developers working with Solidity receive up to 8 million rupees a year. 

And if you are at a crossroads and have not yet decided what direction in IT will be popular in the near future, then here it is. Blockchain. 

Instead of a conclusion

Crypto programming is a new stage in the development of the developer profession, which is constantly gaining popularity. If you are interested in interesting, promising and money-making work, then you should pay attention to the blockchain development field.
