The European Commission has released a strategic document titled "Web4.0 and Virtual World Initiative," defining Web4 as the new direction for future digital development, aiming to gain technological discourse power. Web4 integrates technologies such as artificial intelligence, virtual reality, and the Internet of Things, emphasizing virtual-real integration and data security, contrasting with Web3's decentralization philosophy. This move reflects the EU's desire to become a global rule-maker in the digital economy and to enhance its leading position in technological competition.
