Developed from 2008, blockchain is, first and foremost, a technology for storing and transmitting information. This technology offers high standards of transparency and security because it works without a central control body. More concretely, the blockchain allows its networked users to share data without an intermediary.
CHARACTERIZE A BLOCKCHAIN
In practice, a blockchain is a database that contains the history of all exchanges made between its users since its creation. Its main characteristics are:
- The identification of each part is carried out by a cryptographic process
- The transaction is sent to a network (or storage “node”) of computers located around the world.
- Each “node” hosts a copy of the database in which the history of the transactions carried out is recorded. All stakeholders can access it simultaneously
- The security system is based on a consensus mechanism of all the “nodes” each time information is added. Data is encrypted and authenticated by “data centers” or “miners”. The transaction thus validated is added to the database in the form of a block of encrypted data (this is the “block” in blockchain)
- Decentralized security management prevents transaction tampering. Each new block added to the blockchain is linked to the previous one and a copy is transmitted to all the “nodes” of the network. The integration is chronological, indelible, and tamper-proof.
USEFULNESS OF BLOCKCHAINS
The blockchain represents a major innovation that is used in particular in the banking sector. Indeed, historically, blockchain technology was developed to support transactions carried out via cryptocurrencies/crypto-assets (including bitcoins which are the most well-known form) and which have the main characteristic of not depending on an organization centralizer (like a central bank) and to be international.
But its use is not limited to cryptocurrencies. Many fields and sectors of activity, commercial or non-commercial, public or private, already use the blockchain or plan to do so in the years to come. The uses of blockchains and other technologies include:
- In the banking sector, technology opens up the possibility of validating transactions without the intermediary of a clearing house, which should make it possible to certify transactions in much shorter timeframes. The blockchain can also promote the sharing of information between competing players in a financial centre while respecting the secrecy of their commercial data and, in doing so, facilitate the management of common structures or instruments by reducing contact costs and administration fees.
- In the insurance sector, the contribution of the blockchain is due, for example, to the automation of reimbursement procedures and the alleviation of certain formalities at the expense of companies and their customers, provided that the assumptions and conditions of compensation and damage are clearly established.
- In the logistics sector, the blockchain has two interests:
- ensure product traceability, as well as the memory of the various interventions on a production and distribution chain.
- reduce formalities and create the conditions for cooperation between actors in a sector, particularly in terms of information exchange. This use could also find an application in the agri-food sector for food traceability, particularly interesting in the event of a health crisis.
- In the energy sector, by authorizing the exchange of services and values outside a central management body, the blockchain potentially creates the conditions for implementation on a more or less large scale depending on the technical capacities of local networks. production, exchange and resale of energy to balance supply and demand at all times, which is a major constraint for electricity networks in particular.
But many sectors are potentially affected by the use of blockchain technology: health, real estate, luxury, aeronautics, etc.
Using blockchain has many benefits, including:
- The speed of transactions thanks to the fact that the validation of a block takes only a few seconds to a few minutes.
- Security of the system, which is ensured by the fact that the validation is carried out by a set of different users, who do not know each other. This protects against the risk of malicious intent or hijacking, since the nodes monitor the system and check each other
- The productivity and efficiency gains generated by the fact that the blockchain entrusts the organization of exchanges to a computer protocol. This mechanically reduces the transaction or centralization costs existing in traditional systems (financial costs, control or certification, use of intermediaries who are remunerated for their service; automation of certain services, etc.).
WEB 3.0 AND THE METAVERSE
As conversations began to shift from Bitcoin (BTC) to other larger crypto projects such as Ethereum network upgrades and central bank digital currencies, or CBDCs, media coverage would suggest that widespread adoption of crypto is already well advanced. But it is clear that the majority of people do not know what it is.
The Metaverse (in English) or Métavers (in French) is a generic term for technologies that make it possible to create an entire (virtual) digital universe like our real universe. This universe can be extremely detailed and include a wide variety of different worlds, often also called virtual environments. People can join this Metaverse using different technologies and interact with each other. However, instead of being present in person, the user creates an avatar which is their representation in the Metaverse.

However, the Metaverse doesn’t just want to be a massively multiplayer open-world gaming platform (RPG MMO). It is already beginning to be a virtual space where people work, earn money (by spending it), meet people, and invest in real estate. In short, where you can live another life.
Technologies like Augmented Reality (AR) and Virtual Reality (VR) are important levers for the Metaverse, as they will help create an incredible sense of immersion in another’s skin and in another universe. However, there is one project that may well facilitate mainstream adoption of crypto: Web3.
To better understand the evolution of these two technologies, an illustration between Web2 and Web3 as support for the Metaverse.

NFTs (NON FUNGIBLE TOKENS ) AND THEIR USES
NFT are the three initials of Non-Fungible Token, which translates to non-fungible token. That doesn’t necessarily make things any clearer. Therefore we must detail the notion of “non-fungible”.
For example, bitcoins or €100 bills are fungible. Even though each note is unique, it will have exactly the same value as another €100 note. The first mined bitcoin, no matter what platform it is on or who owns it, is the same value as a recently mined bitcoin stored in another wallet.
Conversely, works of art or concert tickets are non-fungible. Something that is not fungible cannot be replaced or divided. It’s unique. They are objects of the same nature, but which have their own characteristics and their own usefulness.
We talk about “tokens” when they are digital units, which are exchanged with blockchain technology: 3D visuals, objects in a video game, or even a piece of land in a fictional universe.
The NFT can therefore be defined as follows: it is the digital title of ownership of a non-fungible token. NFTs can be classified into different categories according to their nature and usefulness:
- collectibles: a collection of digital objects, or a work of art for example.
- metaverses: virtual worlds.
- online gaming tokens.
- utilities: they provide a service to their owner.
Some NTFs may belong to more than one category. They are traded on online marketplaces dedicated to NFTs, connected to the blockchain.
The value criteria of an NFT: This young technology has a future ahead of it, but it could lead to some abuses. Many investors seek to speculate on this trend which, although it is a resounding success, is still very volatile and full of scams. The vast majority of sold works and NFT projects will never have value, simply because no one wants them.
Some NFTs have artistic value: They are works valued independently of the fact that they are digital, in the same way as a painting in a museum. The blockchain does not have a preponderant role in the evaluation of their price, it is simply the art market. Overall, price is defined by what an artist’s fan is willing to invest.
The value of an NFT can also depend on its usefulness: Becoming a member of a club, meeting other holders or the artist himself, being more powerful in a video game, acquiring and showing a certain social status, etc. .
