Key Web 3.0 features and technologies

Several key Web 3.0 features define what this third generation of the web will likely be all about:

• Decentralized. Unlike the first two generations of the web, where governance and applications were largely centralized, Web 3.0 will deliver applications and services through a distributed approach that doesn't depend on a central authority.
• 
  
• Blockchain-based. Blockchain decentralization is the enabler for Web 3.0's distributed applications and services. With blockchain, data is managed and validated on a broadly distributed, peer-to-peer network. Blockchain also employs a theoretically immutable ledger of transactions and activity, which helps to verify authenticity and build trust among blockchain participants.
• 
  
• Cryptocurrency-enabled. Cryptocurrency is a key feature of Web 3.0 that is expected to largely replace the "fiat currency" issued by government central banks.
• 
  
• Semantically organized. The idea behind the Semantic Web is to categorize and store information in a way that helps "teach" an AI-based system what data means. Websites will be able to understand the words in search queries the same way a human would, enabling them to generate and share better content.
• 
  
• Autonomous and artificially intelligent. More overall automation is a critical feature of Web 3.0, and it will largely be powered by AI. Websites equipped with AI will filter through and provide the data individual users need.
