Web3:

• Decentralized data storage on blockchain networks, reducing the risk of single points of failure or data breaches.

2. Authentication and Identity Management

Web2:

• Relies heavily on centralized username/password systems and third-party authentication providers.

Web3:

• Utilizes decentralized identity protocols and blockchain-based authentication methods, enhancing security and privacy.

3. Smart Contracts Security

Web2:

• Traditional contracts are prone to manipulation and disputes.

Web3:

• Smart contracts on blockchain networks are immutable and execute automatically, reducing the risk of fraud and ensuring transparent and secure agreements.

4. Cryptography for Security

Web2:

• Limited use of cryptography for securing data and communications.

Web3:

• Extensive use of cryptographic techniques for securing transactions, identities, and data, providing a higher level of security.

5. Consensus Mechanisms

Web2:

• Typically relies on centralized decision-making and trust in a single authority.

Web3:

• Implements decentralized consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS), ensuring network security through distributed validation.

6. Privacy

Web2:

• Often involves centralized platforms collecting and monetizing user data.

Web3:

• Prioritizes user privacy with cryptographic techniques and decentralized data control, reducing the risk of unauthorized data access.

7. User Ownership of Data

Web2:

• Users have limited control over their data on centralized platforms.

Web3:

• Users own and control their data, deciding what information to share and with whom, enhancing privacy and security.

8. Permissionless Innovation

Web2:

• Innovation is subject to centralized control and approval.

Web3:

• Permissionless innovation allows developers to create decentralized applications without requiring approval, fostering a more open and inclusive environment.

9. Immutable Record Keeping

Web2:

• Centralized databases may be subject to alterations or deletions.

Web3:

• Blockchain’s immutability ensures that once data is recorded, it cannot be altered or deleted, providing a tamper-resistant record.

10. Attack Surfaces and Vulnerabilities

Web2:

• Centralized servers and points of control create attractive targets for cyber attacks.

Web3:

• Decentralized networks distribute attack surfaces, making it harder for malicious actors to compromise the entire system.

Adopting Web3 security principles brings about a paradigm shift by emphasizing decentralization, cryptographic techniques, and user-centric control. These differences reflect the evolution toward a more secure and resilient digital landscape.
