There has been a lot of buzz around web 3.0 in recent years. While web 2.0 remains popular, web 3.0 is gaining traction in every industry. This article aims to explain what web 2.0 and web 3.0 are all about, as well as some of the contrasts between the two.
Web2.0
Web 2.0 is the term for the phase of the internet that we’ve been utilizing for more than a decade. User-generated content, adaptability, interaction, and a centralized database system are just a few of its features. The majority of popular websites, such as Facebook, Twitter, and Nairaland, use Web 2. Despite the numerous benefits it has brought to our lives, web 2.0 still has several significant drawbacks. Among them include centralization, data security, and other concerns. Most large organizations sell their customers’ data to ad companies without their awareness in order to generate more money. In another case, if you recall, a microblogging platform banned a sitting president for violating its terms and conditions a few years ago. Because it is a centralized network, this was possible. As a result of this issue, a new web technology that promotes decentralization emerged.
Web3.0
The concept of centralization, or, to put it another way, intermediaries, is gone with Web 3.0. Instead of using a centralized database, Web 3.0 uses the concept of storing data on a blockchain. A blockchain is a collection of interconnected blocks that store data and states in sequential groups. The data and states are duplicated in each block. Blockchain is similar to a linked list, but it differs in that blockchain uses a hash to refer to the previous block, whereas a linked list uses a pointer.
To validate new blocks before they are added to the block chain, blockchain employs a concept known as consensus mechanism(all nodes must come to an agreement before the new blocks are added). Web 3.0 creates a transparent system because all users have access to the network, as opposed to Web 2, where only the organization has access to the data .It is difficult to change the blocks after they have been added in the sense that when a user changes a block, he must also update other existing blocks in order to ensure the same copy of data is in each block, making it a difficult and secure process.
While web 3.0 has solved the issues of centralization and user privacy, it still has to deal with the issues of cost efficiency and scalability. Adding a block to the blockchain consumes a significant amount of energy and money, resulting in resource waste.
Web 3.0 is still in its early stages, so there is still much to look forward to in the coming years as the world adjusts to a new web technology. Keep an eye out for more web 3 contents from me.
