Want to become a developer and don’t know where' to start? Wondering how long it takes to find your first job in a crypto company? So this tutorial is for you whether you are an absolute beginner in code or already a confirmed developer!
Becoming a developer does not require a degree but a good knowledge of technology: whether to develop dapps or blockchains. In addition, you will need to have good knowledge of the world of crypto and smart contracts.
Blockchain is by far one of the best industries for developers in 2022 for many reasons:
– This is one of the highest paid skills in computer science
– You can earn passive income using blockchain
– It is a booming industry that offers many exciting projects
Without further ado, let’s begin to understand why knowing how to code in the world of crypto is such an in-demand skill.

Why use blockchain?
Most of these are public, which means that you can go back in time and observe the different transactions since the first block (Genesis block). For example, if we used the blockchain to vote, we could check that our ballot has been taken into account.
Obviously this would mean that other people also have access to this information but they will not be able to look up your name in the blockchain to see who you voted for, all this information would be encrypted.
The makes it possible to operate with agents who do not need to trust each other because the transactions are validated by the community. Where on a centralized application, people who have certain additional rights could abuse the system and give themselves points or money with their administrator access, the blockchain prevents this kind of abuse.
All the computers that validate the network must agree on the transactions and if a fraudulent transaction appeared, they would reject it or at worst, clone the blockchain to start from the block preceding the transaction that we want to reject (like this was the case for Ethereum and Ethereum Classic).
Who uses blockchain?
The use cases of this thing are always more numerous and large companies have understood this well. In 2022, it is no longer just banks and the world of finance who are interested in this.
Decentralized Finance or DeFi
Decentralized Finance or DeFi is a set of decentralized applications that provide access to financial products such as loans, savings and the exchange of goods such as other tokens or NFTs. DeFi is intended to replace current finance.
What are they doing?
What are developers doing? The term developer can refer to a person who develops or the person who develops decentralized applications or Dapps.
1. Blockchain core developers
Core developers build a itself: they create the protocols, foundations and back-ends that will run decentralized applications. Blockchain core developers use programming languages like Python, Go, and Haskell.
2. Decentralized application developers
Dapps developers create Dapps, the web and mobile interfaces with which users interact. When we talk about a blockchain developer, it is more common that it is this kind of developer we are talking about. Decentralized application developers use programming languages like Solidity and Javascript.
3. How to learn blockchain in 2022?
Depending on your skills and your will, there are several paths available to you to start your career in 2022. You may be new to computer programming, so it will be easier to have a plan with intermediate steps to get to your goal.
If, on the contrary, you already know how to code in one or more languages, you can use your current knowledge to start playing with technologies.
Become a developer when you don’t know how to code
Becoming a developer when you have no skills or experience in IT or in the crypto world can be complicated. A mountain rises in front of you but no worries, you just have to put one foot in front of the other and start again.
Before getting into programming, you will need to understand some concepts and then practice with easier programming languages.
How long will it take to become a developer?
For an experienced developer, it will take 1-6 months. For an absolute beginner, it will take 6 months to 1 year. The answer to this question obviously depends on your experience in programming and the time you are willing to devote to your learning.
Which language for the blockchain?
Several languages are used for the most popular projects. Here is a list of languages that you will need to learn depending on what you want to do on the blockchain:
1. Solidity
Solidity is Ethereum’s language for coding smart contracts. If you want to code your Dapps, this is the must-have language. It is very close to JavaScript in terms of its syntax and quite easy to learn.
2. JavaScript
JavaScript is everywhere' in 2022 and the world is no exception. With JS you can write the front-end of your Dapps but also write tests for Smart Contracts, interact with other frameworks and libraries like Web3 and React.
3. Rust
For decentralized applications on the Solana blockchain, it is with Rust that it happens. Rust is a very fast and secure system language but a more complicated one to learn than the other languages in this list of blockchain languages.
4. Python
Python is also an extremely popular language and it is only natural that many libraries and frameworks for interacting with the blockchain have emerged (such as web3.py). In addition Python allows you to code the back-end of the site with frameworks like Django or Flask.
5. C++
The C and C++ languages are used for the development of certain blockchains such as that of Bitcoin for which C++ is the majority language ahead of Python!
6. Haskell
Haskell has grown in popularity in recent years and is also the programming language used by the core developers of Cardano, one of the most popular cryptocurrencies.
There is much more to know but the points above can give you an idea of what you will have to face in your quest to become a blockchain developer.
