The last time I wrote on Medium was during COVID-19 lockdown(wow such a long time). So I was opportuned to get into this year’s edition of Zuri training with Nestcoin on Blockchain technology with a competition on Blockgames. Which brought about this article ‘Major Differences between Web 2.0 and Web 3.0’.

I’ll start with explaining what Web 2.0 & 3.0 is. Web 2.0 (from 2004 -Now), is the second stage of the World Wide Web revolution where there is interactivity not just static web pages, this means we don’t just get information from web pages but the web pages also get information from us unlike the first stage of web which was just read-only. Web 3.0 is said to be the next evolution of internet to create more intelligent, connected and open websites in a decentralised system.

Moving to the differences; in Web 2.0 there is a problem of Lack of control of security of data due to hacking, human error, insufficient authentication control etc. While in Web 3.0 it overcomes issues of security using advanced technology such as Blockchain technology; a decentralised system, encrypted and cross checked. Because Web 3.0 is decentralised which means data is not saved in one big server in an office but different computers all over the world, which makes it impossible for hacking.

centralised & decentralised system

Looking at the Diagram above which is good a representation of Centralized & Decentralized System you’d notice for the ‘Pre-Blockchain’(Web 2.0) there’s a Central server being connected to and once any harm happens to it data has been breached and can be lost. But looking at the second one which represents Web 3.0 because of its decentralized system the fall of one computer doesn’t breach data. Also note that each Computer still has an encryption that secures it.

Another major difference between Web 2.0 & 3.0 is data privacy and sharing. In Web 2.0 companies started collecting data about us (e.g Social media platforms, Internet searches; our likes, events etc)to serve us better to stay on their platform longer which meant more money for them, but at the same time they could package data about us then sell to advertisers, though we gave it out freely because we wanted to try out cool functionalities, products or apps. You can call it an ‘Age of targeted advertising and lack of privacy’.

For example, Mr Ade started getting parenting ads (through machine learning) because he and his girlfriend share the same email address or IP address and searched on symptoms of pregnacy at the same time posting about the issues of menstration and ovulation on social media and with machine learning algorithm those Parenting platforms could predict if she was pregnant. Before Mr Ade finds out from her she is pregnant the Parenting platforms already knew. Which could either have a bad or good effect in thier relationship.

So basically in Web 2.0 you are the product and you don’t have control of your data.

But in Web 3.0, you own your data, you have full control of your data and how it is used.

So a situation whereby you make a social media post and due to some reasons the social media brand takes it down, it doesn’t happen in Web 3.0 because instead of your post being on one of the social media brand servers, it is theoretically on thousands of computers all over the world like in the diagram above. Therefore, you can call it “Age of Freedom’’.

So do you love the concept of Web 3.0 or would want to remain with Web 2.0?
