Blockchain technology offers numerous advantages. Below is a brief overview of its key features:

1. Decentralization: Blockchain operates without a central authority, with data distributed across multiple nodes, reducing the risk of single-point failures and enhancing system stability and censorship resistance.
2. 
   
4. Transparency and Traceability: All transaction records are public and immutable, allowing anyone to verify transaction history, making it ideal for applications requiring high transparency, such as supply chain management.
5. 
   
7. Security: Cryptographic techniques (e.g., hash functions and public-private keys) protect data, preventing unauthorized tampering, suitable for financial transactions and sensitive data storage.
8. 
   
10. Immutability: Once data is written to the blockchain, it is nearly impossible to alter, ensuring data integrity for scenarios like contracts and identity verification.
11. 
    
13. Efficiency and Cost Reduction: By eliminating intermediaries and enabling automated execution (e.g., smart contracts), blockchain reduces transaction costs and improves efficiency, particularly in cross-border payments and contract execution.
14. 
    
16. Programmability: Smart contracts enable the automatic execution of predefined rules, minimizing human intervention, and are applicable in fields like finance, insurance, and logistics.

Application Scenarios

• Finance: Fast cross-border payments, decentralized finance (DeFi).
• 
  
• Supply Chain: Tracking product origins, preventing counterfeiting.
• 
  
• Healthcare: Secure storage and sharing of medical records.
• 
  
• Copyright Protection: Ensuring ownership of digital content.
