Web 3.0 is an emerging iteration of the world wide web that utilizes blockchain technology to introduce decentralization, security, and digital ownership. Some key features of Web 3.0 include decentralization where content is stored on distributed networks instead of central servers, use of smart contracts to ensure reliable and secure transactions, and digital identities represented by users' wallet addresses. Web 3.0 aims to give users more control over their data and interactions online through these blockchain-enabled features.
