Do you want to specialize in the blockchain ecosystem? Find out what training courses on blockchain are available today, whether they are available on the Internet or whether they are diplomas from specialized establishments. Here is our selection of the best training available today to create expertise in blockchain technology.

The blockchain and cryptocurrency ecosystem is unique and interesting in that it is still totally innovative, and that it is one of the environments in which diplomas are not necessarily necessary to start a professional activity.

This is why today it is quite possible self-taught training in “blockchain professions”. Many tools exist for this purpose on the Internet, and we detail them in this article.

In addition, diploma solutions exist today like the Alyra school or the Ecole Polytechnique Executive Educationestablishments that provide distance training allowing you to build up a wealth of solid and recognized knowledge.

Where to start to learn blockchain easily?

The blockchain developer business is constantly evolvingboth in terms of the multitude of languages ​​that exist and for their different use cases.

C++, Java, Rust, Python, Vyper, Go, etc. There are countless different programming languages ​​to learn in the blockchain universe. Nevertheless, it would be relevant to learn Solidity as the first programming languagethe latter being that of the Ethereum (ETH) blockchain and one of the most used in the ecosystem.

Taking its influences from JavaScript, C++ and Python, Solidity notably allows the development of smart contracts and to interact with the Ethereum Virtual Machine (EVM), the keystone of the Ethereum ecosystem which allows interoperability with other products developed on the same structure.

Today, some solutions exist to learn the Solidity language in an interactive and intuitive waysuch as the famous game CryptoZombies which will teach you how to write smart contracts on Solidity by building games in an educational way.

On our side, we have also written a step-by-step tutorial allowing you to develop your first smart contract with Solidity. The latter does not require any particular prior knowledge and will also allow you to familiarize yourself with the Truffle, Drizzle and React tools.

Node Guardians

If you want to learn the Solidity language while having fun and having a real sense of progression, we advise you to embark on Node Guardians, you will find programming lessons in the form of quests and campaigns in the style of an RPG.

You will be rewarded when you complete said quests with equipment and with points allowing you to progress your skill tree. The difficulty in the Node Guardians universe is increasing and you will have the opportunity to start with a detailed tutorial to take your first steps on GitHub.


In addition to the Solidity language, the OpenClassrooms site will allow you to learn many programming languages such as Python, JavaScript, Java, C and many more, but above all, totally free and in French.

Free Code Camp

Finally, the Free Code Camp site will turn out to be a tool of choice, especially for learning to master Python or JavaScript. Note however that the latter, although very complete, is still only available in English.

Blockchain training at Alyra school

Alira school will allow you to obtain a diploma training as a blockchain developer after a 12-week course carried out remotely accompanied by various experts in the blockchain ecosystem.

Rather addressing those already mastering the essential components of IT development (JavaScript, NodeJS, HTML and CSS, etc.), the blockchain developer training provided by Alyra will bring you a content-rich and continuously updated library supported by the expertise of the speakers and trainers.

Oriented towards development on the Ethereum blockchainthis training will allow you to master the environment specific to this ecosystem, in particular Truffle or Hardhat, all structured around Solidity, the language of Ethereum and EVM-compatible blockchains.

Alyra training overview

After this training, you will be able to deploy a smart contract on a blockchain after learning to master Solidity and building decentralized applications (dApps).

As with all training provided by Alyra, blockchain developer training can be funded via your professional training account (CPF), through your employer via OPCOs if you are an employee, or through Pôle Emploi if you currently have jobseeker status.

In total, Alyra’s training lasts 120 hours, which amounts to 10 hours per week. Regarding the cost of the training, the latter amounts to €3996.40. At the end of his training and once the final exam has been validated, the learner will be given a diploma attesting to his skills from the Alyra school.
