<p class=Cryptocurrencies are notably part of the web3 revolution

A fashionable concept that agitates the technological sphere as much as communication people, web3 is presented as the new version of the Internet, more decentralized and based on the chain of blocks (blockchain) , the technology behind non-fungible tokens (JNF, or NFT) and cryptocurrencies.

It seems to be more of a marketing phrase than x27;a reality for the moment, however, criticized the boss of the car manufacturer Tesla, Elon Musk, at the end of December, for emphasizing the catch-all character of web3, like other popular concepts such as the metaverse .

Web3 would be the third age in the history of the Internet, successor to web 1.0, which reigned from the early 1990s until the mid-2000s, and web 2.0, hegemonic since the decade 2010.

Embedded by actors like Yahoo! or AOL, web 1.0 refers to the first uses of the Internet with its static pages allowing information to be consulted essentially, or the sending of e-mails.

Web 2.0 marks the era of a social and interactive Internet, where the public can produce and circulate multimedia content. It consecrates the reign of a handful of large centralized platforms such as Google, Amazon or Facebook.

Concept attributed to Gavin Wood, co-founder of the Ethereum blockchain, the web3 returns to the idea of ​​a decentralized Internet, where users would control their own data, without the help of intermediaries.

To the number three (three in English) is thus added the meaning of free (free), evoking the return of an Internet more independent of States as net giants, as it was originally.

The web3 is intimately linked to blockchain technology, a sort of immense digital register shared between a multitude of users, without central authority and deemed unfalsifiable, listing the entirety of the ;transaction history.

Born after the 2008 financial crisis, the most famous blockchain is that of Bitcoin and its associated cryptocurrency, which is totally virtual. Many others have since been launched such as Ethereum, Solana or Polygon.

It is on these blockchains that web3 projects and applications rely, such as non-fungible tokens, non-reproducible digital certificates of authenticity that derive their value from the real or virtual object to which they are attached. attached. Enough to give a person as much decision-making power as ownership over what they create or consume on the network.

With web3, people create value, but also capture some of it, which changes everything for artists, for example. It's a web that belongs to them, where they regain control over creation and what they own, Nicolas Julia, founder of Sorare, a French online game company, told AFP. exchanges of stickers in the form of JNF.

This is what will make it possible to reinvent a whole bunch of industries, be it the x27;art, music or sport, he adds.

Although they are linked, in particular by blockchain technology and the possibility of holding digital assets such as JNFs within them, the web3 and the metaverse remain two different concepts.

Propelled to the front of the stage in the summer of 2021, the metaverse designates a digital and social universe, supposed to extend physical reality via augmented or virtual reality, and to take the Internet from 2D to 3D.

Is its promise enough to amalgamate it with the web3 revolution, while the metaverse is carried in particular by Meta (Facebook), one of the companies flagships of web 2.0 and symbol of a centralized vision of the Internet?

The answer will be given in several years, because, today, the web3, we still don't know what it is, summarizes with AFP Julien Pillot, specialist in digital and cultural industries.

Either we are on the vision pure ste of a completely decentralized Internet, or on a definition based only on the capacity of immersion, he adds, predicting an inevitable controversy in the future between the two visions.
