21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)...

Der Vater des World Wide Web, Tim Berners-Lee, betrachtet die dezentrale Datenbanktechnik Blockchain nicht als die praktikabelste Lösung für den Aufbau der nächsten Generation des Internets. "Ignorieren Sie den Web3-Kram", riet der Physiker und Informatiker dem Publikum am Freitag auf dem Web Summit in Lissabon laut dem US-Sender CNBC. Er zeigte sich demnach von den Zukunftsplänen der Krypto-Visionäre überhaupt nicht überzeugt.

Web3 "ist gar nicht das Web"
"Es ist wichtig, Klarheit zu schaffen, um die Auswirkungen neuer Technologien zu debattieren", erklärte Berners-Lee dem Bericht zufolge auf der großen Konferenzbühne. "Man muss verstehen, was die Begriffe, über die wir diskutieren, tatsächlich bedeuten, jenseits der Schlagworte".

Der Informatiker und Physiker bezeichnete es demnach als "echte Schande", dass "die Ethereum-Leute" die bereits existierende Bezeichnung Web3 "für die Dinge" übernommen hätten, "die sie mit Blockchain machen". In Wirklichkeit sei diese Form des Web3 "gar nicht das Web".

Take a moment and think of everything wrong with the online world, from data breaches to violations of privacy to the overweening power of big tech.

Then imagine them disappearing. Gone. Just like that.

Sounds appealing? Well, you've just heard the first line of a sales pitch-cum-revolutionary manifesto that's gaining traction in San Francisco and Washington DC. It goes by the name of web3.

The gist is familiar from revolutionary statements throughout history. Wrest power from the establishment, return it to the people, make everyone happier and richer along the way.

The tools we're told can achieve this are as modern as it gets. The heart of the plan is to rebuild the foundations of the web using the blockchain technology that underpins cryptocurrencies such as Bitcoin.

According to Web3's backers, it is possible to take anything - or, indeed, everything - that is online and put it on the blockchain, the energy-intensive ledger which enables data to be stored collectively without the need for a central record-keeper.

First, there was web1 – aka the internet we all know and love. Then there was web2 – the user-generated web, heralded by the arrival of social media. Now, wherever we look, people are talking about web3 (or sometimes, web 3.0) – the supposed next big evolutionary leap forward of the internet. But what is it, exactly?


What is Web3 All About? An Easy Explanation With Examples 

Well, opinions on this differ somewhat. Web3 is currently a work-in-progress and isn’t exactly defined yet. However, the main principle is that it will be decentralized – rather than controlled by governments and corporations, as is the case with today’s internet – and, to some extent, connected to the concept of the “metaverse."

Before we start – just to avoid confusion – it’s worth mentioning that, until a few years ago, the term “web 3.0” was frequently used to describe what is now known as the “semantic web." This was a concept put forward by the original "father of the internet," Sir Tim Berners-Lee, for a machine-to-machine internet. Language is defined by its use, and the term is more frequently used to describe something else now. However, Berners-Lee’s concepts are considered to be a part of what we now call web3, although not the entirety of it.

Web3 : une université de Hong Kong va lancer des campus dans le metaverse
L’Université des sciences et technologies de Hong Kong prévoit d’utiliser le metaverse dès septembre de cette année, afin de connecter ses étudiants à son second campus basé à Guangzhou. Cette expérience Web3 pourrait révolutionner l’enseignement supérieur si elle venait à se démocratiser.

The amount of scams and fraud in the NFT space is overwhelming," the internal letter, which over 400 employees have signed, reads. "We implore you to reconsider."

Indeed, the NFT space is rife with shady dealings and theft. In January, OpenSea, which bills itself as "world's first and largest NFT marketplace," admitted that "over 80%" of NFTs minted using its free minting tool "were plagiarized works, fake collections, and spam.

In a nutshell, it’s a domain name for your crypto wallet. It works just like it does on the internet (like www.thenextweb.com) and helps you easily find a site. A .eth domain name makes it easier to link to your wallets and apps on web3.

Technically, your wallet address looks something like this: 0xD8046FBC80020b35c7d90B4Cb2C04FfA7446AE25.

This string has 42 characters, so there’s no way in hell you’re going to remember it. So if a friend asks you for your wallet address, it’s easier to send them “blah.eth,” rather than this long string.

Plus, if you get even one character in the string wrong, you might end up sending cryptocurrency to someone else — and there might be no way to recover those coins.
