Web 3.0, also known as the third-generation internet, emphasises 'decentralisation' and aims to accelerate the delivery of personalised information to create a more open internet environment through technologies such as artificial intelligence and blockchain. Without relying on third-party intermediaries, Web 3.0 not only improves efficiency, enabling businesses to respond to changes in a timely and flexible manner, but also ensures information security, effectively reducing the risk of data leaks. Web 3.0 offers numerous applications, including decentralised finance (DeFi), which enables individuals to conduct financial transactions, lending, and investing via smart contracts without intermediaries. Furthermore, Web 3.0 supports decentralised application markets, decentralised identity verification, and trustless social networks, empowering users to participate in the development and operation of decentralised applications.
