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 developers  doing? The term developer can refer to a person who develops or the person who develops decentralized applications or Dapps. You can find some really great developers if you just click on seattlesoftwaredevelopers.com.

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.

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.
