Here's what I got to know about web 3. Web3's goal is to protect users' data and activity from trackers. More like making it easier for everyone to surf the net like some pro hacker, without leaving a trace that you were there(visited a website).

First, every device has an IP address through which it connects to the internet. IP address makes it easy to people to track down the data of a person surfing the net including the search history, details you enter on websites, and all. Whenever you surf the net without masking your IP address you are visible and traceable on the internet. Incognito mode and private tabs don't hide your identity on the internet. They are more like a filter to collect sensitive data as tracing the activity of private tabs would make it easier and faster for trackers.

Who collects your data? The internet service provider and the servers hosting the websites. The internet service provider is the network through which you are accessing the internet. They can control what websites you can visit. The process is simple. They just find out the servers hosting the websites and block your IP address from accessing those servers thus blocking the websites. When I say servers hosting websites, they don't belong to thousands of companies. They are managed by a handful of major companies. So if you surf many websites daily, most of them would belong to a single server service provider. So yeah most of your activity can be recorded by a single company and they can sell your data to advertising companies.

As you can see most of the control of your activity online is controlled by third parties and you never know what happens to your data online. 

You might come up with an argument that using VPN would solve this problem. Yeah, it does solve the problem to some extent. It masks your identity from your ISP and trackers on the net. But due to some regulations in some countries like China, India, etc... VPN services don't work as they should. In India, VPN service providers are forced to keep a log of users' data to monitor illegal activities on the dark net. Even VPN is not so secure as the VPN service provider can still keep a record of your activity online.

Here comes the idea of WEB 3. It proposes to make the user's device a server for websites, kind of distributing or breaking down huge servers into smaller ones distributed all over the world and connecting those servers through blockchain technology to make tracing the servers a bit tougher and add to the security of servers. So what exactly does this solve? 

1. This makes it tough for ISPs to block any website as they don't know on what server the website is hosted. 
2. Even if a server breaks down the probability of websites going offline becomes less as they are not being hosted by huge servers(in a single location) and fixing the server also becomes easier(as it's not a huge server).
3. As people are stopping crypto mining due to power issues in some countries, WEB 3 would have an edge on this too. Even if there is a blackout in a country, the hosting services won't go down as they will be hosted by other servers from other countries. This interconnectivity is the magnificent thing that WEB 3 offers.
4. It makes it hard for trackers to collect your data as it's tough to track you from one website to another as all websites will be encrypted by blockchain technology.

Is WEB 3 Invincible? Well, I would say no. It's because even though it's tough it's not impossible to break through this system. If trackers take direct control of your device instead of tracking you online, the whole thing of privacy wouldn't make sense. As you know about the emergence and usage of blockchain for security is increasing rapidly, we can't be sure that no other technology would be discovered which can break through the blockchain system and track down the activity of users.

It's better to upgrade to WEB 3 for now as it's the most secure way to surf the internet now. So yeah let's hope that we get to see more advances in the technology that would far surpass the blockchain system.

It might take some(loooong) time for WEB 3 to be practically possible as most of the web hosting servers are managed by big players in the industry.

Web 3, simply put, is more like the proof of work mechanism. People would host websites, and get rewarded for processing each request for accessing the websites in cryptocurrency. But it's not that crude though.

How to access this WEB 3 then? There are a few search engines coming up with zero data collection policies like DuckDuckGo and browsers like tor, brave, etc... Switching to these browsers and search engines would be the first step towards WEB 3 through Web 3 is not about how you access the internet but about how you are accessing the websites and what those websites can do with your data.

PS: No matter how impregnable a castle you build, there is always a way to break through it. It just shows human intelligence and evolution. It would never end with Web3.

PS 2: I'm not an expert regarding these topics, but this is my opinion on web3(I made it after days of research).
