In theory, Web3 will allow you to go online without the need for search engines such as Google or social media like Facebook. But some say Web3 is under the control of the venture capital industry.

Web3 has become the latest buzzword to get tech and cryptocurrency enthusiasts talking. While some are excited at what is being dubbed as the next phase of the Internet, others, including Elon Musk and Jack Dorsey, have voiced their concerns over it.

But what is Web3 and can this decentralised vision of the Internet work?

What is Web3?

Put simply, Web3 is an umbrella term for an online ecosystem that cuts out the big middlemen on the Internet. So, platforms on Web3 are not owned by central gatekeepers and you wouldn’t navigate the Internet through search engines such as Google.

It uses blockchain, the same system used by cryptocurrencies and non-fungible tokens (NFTs).

What’s so bad about Web 1.0 and Web 2.0?

The first version of the world wide web was launched by Sir Tim Berners-Lee in 1989. Back then, the few people who had the knowledge to could put information online in a decentralised way.

Web 2.0 came some 10 years later and started with the development of tools that were easy to use, allowing anyone to upload content online via the tech giants such as Google, Twitter and Facebook (now Meta).

But these free tools supplied by the tech companies, that allowed everyone to become publishers, was also harvesting our personal data to be used for tailored advertisements and marketing campaigns.

In theory, Web3 will be a combination of the two earlier versions of the Internet but will take the power away from the tech giants and corporations and put it back into the people’s hands.

And instead of exchanging our data to upload content online, users can become participants and shareholders by earning tokens on the blockchain system, which will allow you to have a say over a network.

“Web 2.0 is the transmission of information but Web3 is the transmission of values,” said Pascal Gauthier, CEO of the crypto hardware wallet Ledger, one of France’s unicorns.

“We can see that currently on the Internet, your experience becomes bad as soon as you have to take out your credit card,” he told Euronews Next, adding, Web3 basically fixes issues such as payments.

How does it work?

In the Web3 world, search engines, marketplaces and social networks will have no overriding overlord.

So you can control your own data and have a single personalised account where you could flit from your emails to online shopping and social media, creating a public record of your activity on the blockchain system in the process.

A blockchain is a secure database that is operated by users collectively and can be searched by anyone. People are also rewarded with tokens for participating.

It comes in the form of a shared ledger that uses cryptography to secure information. This ledger takes the form of a series of records or “blocks” that are each added onto the previous block in the chain, hence the name.

Each block contains a timestamp, data, and a hash. This is a unique identifier for all the contents of the block, sort of like a digital fingerprint.

Don’t we already have Web3?

The idea of a decentralised Internet has been in the works for the last decade with the explosion of cryptocurrencies and blockchain, and there are arguably some early Web3 applications that already exist. But we are not officially in the Web3 world.

Is Web3 too idealistic?

The idea of a decentralised internet may sound far-fetched but big tech companies are already betting big on it and even assembling Web3 teams.

But even if power is taken away from the tech giants, the people currently shaping Web3 are software developers and venture investors. Meanwhile, blockchain networks are not equally distributed and are in the hands of venture capitalists and early adopters.

This week, the former Twitter CEO Jack Dorsey suggested that Web3 is under the control of the venture capital industry, particularly the firm Andreessen Horowitz, an early Facebook backer and a Web3 advocate.

“You don’t own Web3. The VCs and their LPs do. It will never escape their incentives. It’s ultimately a centralized entity with a different label,” the Square’s CEO tweeted.

On Thursday, Dorsey tweeted in response that he had been blocked on Twitter by Marc Andreessen, co-founder of Andreessen Horowitz.

Meanwhile, Tesla chief Elon Musk says Web3 is more of a “marketing buzzword” than reality.

"I’m not suggesting web3 is real – seems more marketing buzzword than reality right now – just wondering what the future will be like in 10, 20 or 30 years. 2051 sounds crazy futuristic," he wrote on Twitter.

Musk also asked where it was, to the annoyance of Web3 devotees.

What are the challenges?

Experts have expressed concerns over how to regulate a decentralised internet, which would make it even more difficult to prevent cybercrime, hate speech and misinformation.

Web3 can also be hard to use but Gauthier says the challenge is not if people can access it easily but if they know how to manage their data securely.

“Anyone on the planet can access Bitcoin or Ethereum today, as long as you have an internet connection. So there are billions of human beings that can access Web3 systems while the same human beings cannot necessarily access the banking system,” he said.

“To understand how Web3 works, there are some mistakes you should be aware of and you have to pay attention to your safety.

“Before, in the financial world, security was provided by your bank. All of a sudden, now, you have to do it yourself since you own the privileges and you can manage your money online. So that means that there is a whole education and understanding part of the security issues that are important.”

Building the technology to make Web3 fully decentralised, which has never been done before, is also one of the challenges.

“Creating decentralised tools is not easy. Centralised systems are easier to build but less transparent,” said Úrsula O’Kuinghttons, director of public relations of the blockchain infrastructure company Parity Technologies, who also works with the Web3 Foundation.

“Some blockchain hybrids are a combination of centralised and decentralised systems but creating 100 per cent decentralised tools is the hardest and the longest part. But this is what Web3 is truly about,” she told Euronews Next.
