In this article, we would discuss the difference between web 2.0 and web 3.0.

What is web 2.0? Web 2.0, the current version of the internet widely used, simply refers to the internet applications that allow sharing and expressing of user generated content. It is mainly characterized by dynamic content and the social media.

What is web 3.0? Web 3.0 refers to the next phase of the internet coined by Ethereum co-founder, Gavin Woods. The core concepts of the web 3.0 are: decentralization, trustless, artificial intelligence and connectivity

Major Difference Between Web 2.0 and Web 3.0

1. Decentralization - Decentralization is defined as the absence of a centrally controlled activity. Web 3.0 is heavy on the concept of decentralization while web 2.0 is not. For example, in web 2.0, a tweet made by a user could be censored by Twitter but in web 3.0, there is no governing body to censor any tweet.
2. Database - Unlike web 2.0 applications, web 3.0 eliminates the middle-man. There’s no centralized database that stores the application state, and there is no centralized web server where the backend logic resides.
3. User Data - In web 2.0, users have limited control of how their data is exploited and some web 2.0 applications collect user's personal information based on their policy but with the advent of web 3.0, its users only need to provide their wallet address for authentication thereby giving them control over their data.
4. Public Ledger - The public ledger is used as a record-keeping system that maintains participants' identities in secure and (pseudo-)anonymous form, their respective cryptocurrency balances, and a record book of all the genuine transactions executed between network participants. Web 2.0 transactions are not publicly published while web 3.0 transactions are published on the blockchain accessible to everyone.
5. Money/Currency - Web 2.0 mainly use tenders backed by law as a means of transaction while in web 3.0, tokens/coins created independently are widely used as a means of transaction.

While web 3.0 might prove to be the future, there are still some disadvantages with this new internet but in the meantime, I fully support and would be involved in this revolution.
