If you are reading this blog post on an internet-connected device, you are already an active participant in the modern web. The current web has evolved over the ages and is very different from what it was even a decade ago.

To understand the concept of Web 3 and understand where it is headed, it is important to know where it all began and how it has evolved.

Evolution of the Web

Take a pause and think about how our lives have changed since we started using the internet. Not just our daily lives but the whole society has changed since the Internet.

Over time, the web has evolved considerably, and the applications are almost unrecognizable today. This transformation of the web can be categorized into three parts – Web 1.0, Web 2.0, and Web 3.0.

What is Web 1.0?

Web 1.0 is the first stage in the evolution of the Web and is often referred to as the read-only web. This consisted primarily of static websites with almost zero interaction between users. The users rarely generated any content, hence the name – read-only.

The first iteration of the web, Web 1.0, served static content instead of dynamic HTML. All data and content were served from a static file system instead of a database, and there wasn’t much interactivity with or within the sites.

Web 1.0 characteristics

  • Static websites
  • Content served from a static file system
  • Banner ads
  • Pages were built through Server Side Includes (SSI) or Common Gateway Interface (CGI)
  • Primarily read-only, with users only consuming the information served to them

Web 1.0 – Challenges

  • Slow & clunky
    Every time any new piece of information is added to a web page, it needs to be refreshed.
  • One way information distribution
    Web 1.0 doesn’t support two-way communication based purely on the client pull method.
  • Inefficient Search Technology
    The search technology for web 1.0 focused on the index size instead of relevance.
  • Flawed network
    Web 1.0 completely ignores the power of the network. It is made of only a few writers and many readers, slowing down the process and starving the users of resources.

What is Web 2.0

As social media platforms emerged in 2004, the second stage of the web evolution came to light – Web 2.0. From read-only, the web now changed to read-write. Now, the companies, in addition to using the internet and websites to serve content to the users, also started providing a platform that allowed and encouraged sharing of user-generated content and user-to-user interactions.

For example, an eCommerce website in Web 1.0 would just be a list of products with price lists and product details. Site visitors would look through all the information on the site and then physically go to the store to buy what they liked on the website. Whereas in Web 2.0, users can go to an eCommerce website, make a purchase, pay for it through their preferred payment mode, track delivery, cancel or return orders, and even receive refunds without stepping out.

Gradually, as the number of people coming online increased, only a few top companies started controlling a massive chunk of the traffic and value generated on the web. For example, if you want to find information about any brand or want to fact-check, you would do it on Google. If you are looking for unique musicians or artists, you will do it on Spotify and Instagram, and if you are looking for a particular product, you will do it on Amazon. So, you get the idea, right! These big names essentially have become the centralized data aggregators. They become the middlemen or the intermediaries between the suppliers and the consumers, reaping maximum benefits.

This was also the phase where the advertising-driven revenue model. While users could create content in Web 2.0, they could not own it or benefit from it financially.

Web 2.0 characteristics

  • Dynamic websites
  • Allows participation and user interaction
  • Rich user interface and experience
  • Contains collective intelligence through user engagement

Web 2.0 – Challenges

  • Privacy concerns
    Most of the activity on Web 2.0 is monitored. There is a record of every search, click or tap, video watched, location, personal information, content posted, and more! Web 2.0 has more information about us than even ourselves. The real concern about privacy is – what if all these records were to fall into the wrong hands?
  • Security issues
    There are vulnerabilities in the system, and hackers know where they lie. There have often been stories about successful hacks in spaces containing sensitive and confidential data. Data leaks happen and are a big concern on Web 2.0.
  • Centralization
    Everything is under the control of a single authority, which is fine until they suddenly decide to pack up and leave or make seriously concerning changes. No one has a say in the way things happen in this context.
  • Censorship
    As I mentioned earlier, the system is centralized hence there is a genuine possibility of the administrators censoring or hiding content they see unfit for public consumption. This censorship can conceal the truth, creating an autocratic environment instead of a healthy democracy.

What is Web 3.0?

The concept of Web 3.0 was formulated by Gavin Wood (Ethereum Co-founder). This is stage 3 of the evolution of the Web, which is based on the concept of decentralization. In this version, people or users own and control their own data without any central authority or intermediaries.

Generally, Web 2 platforms are deployed to a server, and the data is stored in a central database which, in turn, is managed by a cloud service provider. Now anyone with access to this server can easily add, remove, or change any information saved there.

For web3 apps or dApps, all the data saved on the network is copied and distributed in a decentralized peer-to-peer network of thousands of nodes communicating with each other under a consensus protocol. Simply put, any data on web3 cannot be changed or manipulated in any way.

Another interesting aspect of Web 3.0 is that it encourages full user participation without monetizing user data.

Web 3.0 characteristics

  • Decentralized
  • Maintains anonymity and privacy
  • High security, quick transactions
  • Resistance to censorship
  • Self-governing
  • Distributed

What are dApps, and what are web3 apps?

We cannot talk about web3 without talking about decentralized apps or dApps. After all, dApps have been deemed the backbone of the web3 revolution. Web 3.0 intends to make the Internet a more decentralized space, and this is true for web3 apps as well. The terms web3 apps and dApps are used interchangeably, and they both mean decentralized, blockchain-based apps in the web3 space.

These apps use smart contracts, and the contracts’ logic dictates the app’s behavior. This eliminates the need for any big company to act as an intermediary. While trying to interact with Web3 apps smart contracts using JavaScript, you’ll definitely come across Web3.js.

What is Web3.js?

The Web3.js library is the basic JS library used for Web3 app development. While working on Web3 apps, you will be using this library to interact with Ethereum. Web3.js can essentially be seen as an Ethereum JavaScript API.

Is it getting a little too complicated for you? Don’t worry. We’re going to help you bypass all this and make your web3 apps without getting into the complexities.
