How is Cryptography Applied in Blockchain?

In blockchain technology, cryptographic mechanisms are mainly used to ensure the integrity, authenticity, and privacy of transaction information.
Cryptography is the core technical feature of the blockchain data core technology (P2P network protocol, consensus mechanism, cryptography technology, account, and storage model). The main cryptographic algorithms used in the blockchain include hash algorithms and encryption algorithms. Encryption consists of two concepts: symmetric encryption and asymmetric encryption, and asymmetric encryption is commonly used in blockchain systems.
