What is Web 3.0? Examples and Applications

Lately, there is a buzzword that almost every tech conversation seems to be around. If you are a tech enthusiast, you must have also come across the word, at least once on the internet: Web 3.0.

The idea behind Web 3 is that it’s coming to change the way we access the internet and the way we use Web 2 apps such as Facebook, Google, Twitter, etc.

The Web Evolution

The web has witnessed tremendous growth and improvement ever since it first started Before Web 3, we have had both Web 1 and Web 2.

What is Web 1.0?

Web 1.0 is the term used for the first era of the World Wide Web evolution, it lasted from 1989 t0 2005. In this era, there were few content creators on the internet while the majority of online users were content consumers. Back then, individual web pages were the common types, these pages were mostly joined by hyperlinks and were either hosted by an Internet Service Provider (ISP) or the owner uses a free web hosting service. Advertisers were not allowed to show their ads while surfing the internet. In order to store, save, view, or print their digital pictures, users made use of an online digital photography website called Ofoto.

Web 1.0 is based on three technologies:

HTML – Hypertext Markup Language, which is the formating language of the web.
URL – Unig=que Respurce Locator. This is the unique address used to find web pages.
HTTP – HyperText Transfer Protocol.

Web 1 being a static web, was not user-friendly since there were no algorithms that could serve web pages, and also, the web pages were basic. Web 1 was more of a one-way setup because the content on these pages was being published by the web owners and there was no way by which users could interact with them, it was a read-only web.

In Web 1.0, the internet could be browsed but could not be interacted with, it can be referred to as the read-only web. Back then, signing up as a user or commenting on articles was not a thing. Take Web 1.0 as a library where you can only get information but can’t make a contribution or change it apart from that, it was very slow as well. The advent of Web 2.0 made the internet more interactive and faster, with the introduction of technology advancements like html5, CSS3, JavaScript and so on which made it possible for startups build to build interactive platforms such as Wikipedia, Twitter, Facebook, YouTube, etc. So while you are receiving information just as in Web 1.0, you can also contribute.

What is Web 2.0?

Web 2.0 is simply a build-on on the first stage of the internet. Instead of the static page found on Web 1.0, it is characterized by dynamic web pages or user-generated content, it was also the era of high growth of social media.

The major difference between Web 1.0 and 2.0 is seen in the fact that web users can create, design, share and publish their work without having any web design or publishing skill, they only do this using the established platforms. These functions are not found on Web 1.0.

Popular sites and applications in the Web 2.0 era are Wikipedia, Facebook, Google, Youtube, Pinterest, Twitter, and various blogs.

Interestingly, this was the time that programming languages such as Javascript, CSS, HTML5 started to gain attention. If we call web 1 the read-only web, then we can call web 2 the read and write web or the social web as it is being commonly called. Web 2 allows content participation from the users which means the web owners do not necessarily have to be sole content creators. Some of the companies that dominate web 2 are Google, Facebook, Amazon, Uber, Airbnb, etc. However, web 2 has its own loophole; it is a centralized system. What this means is that the web 2 companies have control over your data. Some of them use this data for advertising purposes, and that is why you keep seeing a product you attempted t buy from an eCommerce keep reappearing on another website or even apps. Apart from storing and using your data, they can also remove or suspend your account due to a violation of policies set by these platforms. All these can be avoided, and the only way this can be done is to have a decentralized system, and this will bring us to web 3.

However Web 2.0 is not completely free, this is because for you to be on those platforms and be able to interact, you need to first register, and once you do, these companies have access to the data you supplied them such as demographics and as well monitor your online activities such as your interest. They then use these data to serve targeted ads to users on their platforms.

The discussion around data privacy has gone for too long, why should a company have access to your data and even sell it to a third party? This is where Web 3.0 comes in, where the internet will be decentralized that is, there won’t be any central point of control.

What is Web 3.0?

Web 3 is based on a decentralized system where users don’t just help a content creation, but also own part of the network itself. Web 3 is powered by blockchain technology where it uses ethereum to decentralize the network. Another technology it can also use is the IPFS. IPFS is a file-sharing system that can be used to store and share large files, and since the blockchain can not store large files, the IPFS will come in handy.

Difference between web 2.0 and web 3.0

The fundamental difference between Web 2.0 and Web 3.0 is decentralization. In web 3, there is no centralized database where you store the application database. On the blockchain, the applications are stored on a decentralized ledger where distributed nodes all agree on the state of the network.

Where producers are regarded as content creators in Web 2.0, in Web 3.0 they are regarded as owners. In Web 3.0, you won’t need any form of authorisarisation or censorship before you can post anything.

In web 3.0, AI will help websites understand users better, faster and smarter.

In Web 2, developers build applications that run on a single server where the data is owned and operated by central control, in Web 3, applications run on decentralized networks of many peer-2-peer servers leveraging on the blockchain which is usually a decentralized database. In Web 3, participants are able to host one of these peer-2-peer servers or nodes or contribute to the network and be rewarded with a crypto token.

Benefits of Web 3.0

1. Strong Security

The backend infrastructure in web 3 is decentralized across nodes (servers) whose singular purpose is to maintain the network. It is structured such that if any of the nodes goes down, the network still runs. Even if any of the nodes is hacked, the security of the broader network won’t be affected. Moreover, a distributed network such as a blockchain is cryptographically secured, and what this means is that no one can alter the smart contract code unless they have the keys.

2. Data protection

In web 2, the web companies have control over the data you submit to them and they use this to their advantage. In web 3, you will get the advantage of data encryption to protect your information from disclosure and this will prevent large companies from using your information. With this, you can be guaranteed complete ownership and privacy of your data. Moreover, government or organization will be able t suspend or remove your account.

3. No permission required

Another benefit of the web3 and a decentralized blockchain is that you don’t require a permit before you can join any app, all that you need to connect to a Dapp is a web3 wallet such as Metamask.
Single profile across the board

Unlike the centralized platform where users have to create different profiles each time they want to join a platform, in web3 you will only need a single profile that will work on any platform. The users will have control over their data and information and can decide on their own to sell it to advertisers.

4. No restrictions

Some of the web2 platforms place certain restrictions on their platforms such as age limit, gender, geographic locations, etc. Since the blockchain network is accessible to all, all these restrictions won’t hold for web3 because anyone who is on the network has permission to use the service.

5. Easy data collection

With web 3, there will be ease of data collection and increased accessibility to data. This will be possible because you will be able to access data from anywhere with any connected device.
Better marketing experience: Most of the adverts we come across on web3 are not really what we need, and that is why we find them annoying sometimes. With the help of the Artificial Intelligence of web3, advertisers will be able to serve their ads to the right audience. This will ensure that you don’t find any ads annoying again since they will be more relatable and highly beneficial to you.

Challenges of Web 3.0

1. Unchecked online activity

Web3 has no central control, unlike web2. In web2, any crime committed on the internet can easily be traced, But this might not be the case with web3 since it is not regulated, it will make it therefore to be difficult to monitor. This challenge can lead to an increase in the cybercrime rate.

2. Unrestricted web content

An unregulated web may give room to the spread of fake news.  In web 2.0, such news can easily be flagged as fake or removed by the hosting platformS, once it has been reported and confirmed as fake. Apart from the spread of fake news, there are content that viewers need to be warned against before seeing them, some of the web 2 platforms always ensure this. But with a web that is not regulated, there won’t be any limitations as users can come across any content of any sort.

3. Complicated technology

Web 3.0 is a combination of older-generation web tools with cutting-edge technologies, such as Artificial Intelligence and blockchain. Because a lot of people have been accustomed to web 2.0 , adapting to web 3.0 can take a longer time. Due to the technicality involved, only advanced devices will be able to function with web 3 and this will mean that users need to start understanding how it works and how to navigate it. This will be a great challenge to those who always find it difficult to learn new development and will slow the adoption rate of the third web.

Conclusion

The Web 3.0 era will affect a lot of things such as the way we search the internet, the way we buy things online, and even the way we relate (social media). It will revolutionize everything internet including skills such as web development, digital marketing, etc. This means a web developer who already has the knowledge of HTML, CSS javascript, etc. will need an upskill by learning Solidity. For digital marketers, this means that they need no

You can be a champ in Web 2 skills but if you sleep on it, your skills might become totally irrelevant in the Web 3.0 era.

Web 3.0 is still at a very primitive stage, and for you to stay abreast of how things unfold, you will need to always be on the lookout.
