What is Web3 and Why is it Important?

Web 3.0 is a decentralized web built on blockchain, web2.0 and web3.0 have a few some similarity but the major difference is that web3 is decentralized. You can think of Web3 to be read-write-own.

The Early of the Web

The evolution of the web started in the 90s, in other to understand the web better, it would be great to explain the three(3) stages of the web separately. 

WEB 1.0(WEB1)

Tim Berners-Lee invented the World Wide Web(WWW) while working at CERN, Geneva in 1989, He developed a protocol a document formatting protocol,  which is called Hypertext Markup Language(HTML).

Web1.0 which evolved from 1990 to 2004, was mainly a static website that was hosted on a web server.

At that time they were few content creators which is mostly web developers that created static websites that displayed only text and images, users can not interact on the site, they can only read the information displayed on it. This is why web1.0 is called read-only web.

WEB 2.0(WEB2)

Web2.0 occurred roughly around 2004 to now, it can be called participative, interactive, or social web. It was at the time social media and with platforms started emerging.

As web2.0 users you can interact and collaborate with other users on the same platform, and also you don’t have to be a developer in other to create content on the website anybody can be a content creator.

Instead of just reading a web2.0 website, you can contribute to the website by commenting on a post via a news website or social media platform, user can also create a profile on the site, which increased participation.

Web2.0 social web( Podcasting, Blogging, Social Networking, etc.) allow people to share their opinions, experiences, and thoughts. Web 2.0 applications tend to interact much more with the end user. As such, the end user is not only a user of the application but also a participant.

Web2.0 platforms are mostly centralized services owned by big tech corporations like Twitter, Facebook, Apple, Google, and Amazon.

These top companies began to control a disproportionate amount of the traffic and value generated on the web.  Users don’t have control over their data, these companies where users save their data in their centralized database are in charge of the user data and can do whatever they want from it. This is why web2.0 is called read-write web.
WEB 3.0(WEB3)

Web 3.0 is a decentralized web built on blockchain, web2.0 and web3.0 have a few some similarity but the major difference is that web3 is decentralized. You can think of Web3 to be read-write-own.

The term “Web3.0” was coined by Ethereum and Polkadot co-founder Gavin Wood in 2014 while on ethereum. Gavin Wood refers to web3.0 as a decentralized online ecosystem based on blockchain.

Web3.0 is an open, trustless, and permissionless network that enables a future where distributed users and machines are able to interact with data, value, and other counterparties via a substrate of the peer-to-peer networks without the need for third parties.

What Really Happens in Web3.0

In web3.0, developers don’t usually build and deploy applications that run on a single server or store their data in a single database that is centralized. Instead, web3.0 applications are run on blockchains, decentralized networks of many peer-to-peer nodes.


  • Web3.0 is permissionless: Everyone has equal access to participate in web3.0, and no one gets excluded. 
  • Web3.0 has native payments: It uses cryptocurrency for spending and sending money online instead of relying on the outdated infrastructure of banks and payment processors. Crypto wallets like Metamask, Argent, and Trust Wallet enable you to integrate easy, anonymous, and secure international payments and transactions into web3.0 applications.
  • Web3.0 is trustless: It operates using incentives and economic mechanisms instead of relying on trusted third parties.
  • Web3  is decentralized: Instead of swathes of the internet controlled and owned by centralized entities, ownership gets distributed amongst its builders and users.

Important Of Web3

Identity:  You know how frustrating it is to fill out multiple registration forms on different platforms eg Twitter, Facebook Youtube, etc. In web3.0 you can use one personal profile that works across all platforms, eg you can control your digital identity by using ENS Profile and Ethereum address. An Ethereum address provides a single login across platforms that are secure and censorship-resistant.

Users Privacy: The number of data breaches and misuse of users' data recently by top companies should give users to have a rethink, web3.0 solve most of these issues, in web3.0 users can secure privacy by using cryptography.

DAOs (Decentralized Autonomous Organizations):  Are defined technically as agreed-upon smart contracts that automate decentralized decision-making over a pool of resources.

Users with token tokens vote on how resources get spent, and the code automatically performs the voting outcome. This opens up new opportunities for global collaboration and coordination.
Native payments: Web3 uses tokens like Eth and Bitcoin to send money directly to your wallet and requires no trusted third party.
ETH and Bitcoin are a cryptocurrency, It is scarce digital money that you can use on the internet.

Web2 payment infrastructure relies on banks and payment processors, excluding people without bank accounts or those who happen to live within the borders of the wrong country.
