Web2 vs Web3 – The Core Difference

[zainabegum]

• Web2 is the internet we’re all used to: platforms like Facebook, YouTube, or Google where data is stored on centralized servers owned by companies. That makes them gatekeepers, and also prime targets for hacks or misuse of user data.
  
  
• Web3, on the other hand, is built on decentralized technologies (mainly blockchain). Instead of one central authority controlling your data, it’s distributed across nodes, making it much harder for a single point of failure or data breach to occur.
  
  

Why Web3 is More Secure

• Ownership of Data: In Web3, users control their own digital identities and assets through wallets/private keys.
  
• Transparency: Blockchain transactions are public and verifiable, so it’s much tougher for bad actors to manipulate systems behind the scenes.
  
• Decentralization: No single company can shut down, censor, or exploit your data — security is enforced by the network itself.
  
• Smart Contracts: Automated, tamper-proof agreements reduce the risk of fraud compared to traditional centralized intermediaries.
  

Of course, Web3 is still evolving, but the security model is fundamentally stronger because it removes the reliance on “trusting” centralized corporations. Instead, you trust the code + consensus.
