Role of Blockchain in Web 3.0

Web 3.0 is the third generation of internet services which provide websites and applications with the technology to run. Web 3.0 is set to be powered by AI and peer-to-peer applications like blockchain. The key difference between Web 2.0 and Web 3.0 is that Web 3.0 is more focused on using innovative technologies like machine learning and AI to create more personalized content for each user. It is also expected that Web 3.0 will be more secure than its predecessors because of the system it is built upon.

Blockchains are made up of blocks that store information. Each block has a unique “hash” that differentiates it from other blocks. These blocks are then connected by a chain in chronological order. The information stored in these blocks is permanent, which makes it a very secure way to complete online transactions.
This is why cryptocurrencies, like Bitcoin, are built on blockchain technology.
