By adopting a series of cryptographic technologies, such as hash algorithms, encryption algorithms, public key cryptography, Merkle trees, and zero-knowledge proofs, blockchain technology can ensure data security and reliability while protecting personal privacy.↵↵Taking Bitcoin as an example, it uses hashed public keys as personal accounts to protect users' identities, hiding personal information. In addition, Bitcoin allows users to use new accounts for each transaction, making it difficult to infer user identities by tracking account transactions. Although the overall ledger of Bitcoin is public, each transaction record only contains the paying account and the amount involved."}]}],"pr":"e640d9607ab442a63a6b6b87bcc627e76c55cd28a790a1a3d5860aeb1911c678"}
