Web2.0 technologies co-exist with Web 3.0
Web3.0 is the third phase of the internet’s development after web1.0 and web2.0. It is based on a decentralized ecosystem that supports blockchain technology. Web 3.0 leverage machine learning, artificial intelligence, and blockchain to achieve real-world human communication.
The main thing which separates web 3.0 from web2.0 and web1.0 is one can OWN the data on the internet. So, let’s look at the different versions of the Web and the Web 3.0 revolution.
Web 1.0 was the first version of the internet. That was created in the 90s and it was a read-only internet. You could only go to websites and read information. This was an era of an information economy when information is broadcasted on the internet. However, you could not post new information to the internet, these capabilities came with Web 2.0 and in the 2000s, we can call it a platform economy that facilitates read-and-write internet. Instead of just consuming information we can create information, news, blogs, and feeds on social media. We can publish and post the information. Anyone can have a blog, can interact with the internet, and we are not only consumers, but we are also creators of the internet. However, there is one limitation in web2.0 that we do not own the data we create. For example, the tweet we do, and the video we upload, it is the platform that owns the data and has the right to remove data if needed. In Web 3.0, you can read, write, and own the internet. Web 3.0 enables us to move from static content to virtual economies by using AR/VR and blockchain.
So the question arises of how users own the stuff in web 3.0. In terms of infrastructure, instead of on-premise servers or clouds, users will be using blockchain and IPFS Interplanetary File System. The control shifted from being centralized to decentralized or at least way more decentralized than today.
As shown in the figure above comparing the tools that are used in Web 2.0 and the ones that are using Web 3.0, it doesn’t mean that in Web 3.0, we don’t use Google Chrome? It means that other tools provide you a better experience in the more decentralized and Web 3.0 style experience.
So, in terms of storage in Web 2.0, we have cloud providers like AWS, Google Drive, and Dropbox, while in Web 3.0 you have IPFS storage which is a decentralized storage platform, browsers we have Web 2.0, and we have Internet Explorer and Microsoft Edge and Google Chrome. And for Web 3.0, we have browsers like Brave that have cryptocurrency wallets already integrated into them.

Currently, we use things like PayPal and bank accounts, and now we have other wallets like MetaMask and many other wallets where we can own and control our assets, not a third party like a bank.
The same applies to an operating system in web3.0 we will have decentralized apps or Dapps and they run on Ethereum.
Social networks, we used to have Facebook and YouTube, and we even now have platforms like Steem and DTube, which are kind of decentralized social networks, and you own your content. If you publish, for example, a video or a blog post on Steem and DTube, you can earn a little bit of crypto every time someone likes your content.
Let’s take an example of Decentralized land — decentraland, this website is probably hosted on the cloud. It can be AWS or any other cloud server. But they can also be on IPFS Interplanetary File System, which is decentralized cloud storage. What I am trying to explain is that part of the application may still be on the traditional cloud or on-premise server. The however smart contract that you have bought virtual land is on the blockchain. So, every time you buy and sell, for example, a virtual land, this is the part that is on the blockchain, not the website or platform. Imagine putting 5GB of a platform on blockchain and spread across 10K nodes, it will make blockchain very slow and not sustainable.
But the logic, the transactions, the ownership that is a part that will be on the blockchain, and the rest of the platform is going to be kind of in the server or the cloud or IPFS.
