加密
Encryption in the blockchain and cryptocurrency fields refers to the use of cryptographic techniques to protect the confidentiality, integrity, and authenticity of data. Cryptographic technology transforms information into an unreadable form through algorithms, which can only be decrypted by those holding the correct keys. Encryption is used in blockchain to protect the security of transaction data, user identities, and smart contracts. It is the foundational technology for ensuring the security and privacy of decentralized networks and is widely applied in areas such as digital signatures, hash functions, and zero-knowledge proofs.
