2. Basic principles and characteristics of blockchain technology:
Distributed storage: Blockchain data is stored on multiple nodes, each node has a complete copy of the ledger, and the data is highly reliable and secure.
Decentralized management: The data in the blockchain network is jointly maintained by all nodes, and there is no centralized management body, reducing the risk of a single point of failure.
Consensus mechanism: The blockchain network ensures the consistency of all nodes on the ledger through a consensus algorithm, and common consensus mechanisms include Proof-of-Work (PoW), Proof-of-Stake (PoS), etc.
Immutability: Once the data is written to the blockchain, it cannot be tampered with, ensuring the security and trustworthiness of the data.

Chapter 5: The Combination of Artificial Intelligence and Blockchain: A Case Study
Introduction: The combination of artificial intelligence technology and blockchain technology will bring more intelligent and secure application scenarios. This chapter will demonstrate the great potential and value of the combination of AI and blockchain through specific case studies.
Substance:
Case 1: Blockchain-based smart contract application example
Case Introduction: Suppose we choose a decentralized finance platform called "DeFiSwap" as an example, which builds smart contracts based on blockchain technology and provides services such as digital asset trading and liquidity mining.
Effect Evaluation:
1. Increased transaction speed: DeFiSwap uses smart contracts to automate transaction execution without the need for intermediaries, resulting in a significant increase in transaction speed.
2. Cost reduction: Since there is no need for intermediaries, transaction costs are greatly reduced, and users can enjoy lower handling fees.
3. Trust building: The automatic execution and immutability of smart contracts enhance the trust between users, making transactions more reliable and secure.
Case 2: Application case of blockchain technology in the field of medical data security
