Common backend encryption technologies include symmetric encryption, asymmetric encryption, and hash algorithms. Symmetric encryption technology is primarily used in blockchain for encrypting transaction data, ensuring the security and integrity of the data. Asymmetric encryption technology is used for verifying user identities and digital signatures, ensuring the authenticity and security of transactions. Hash algorithms are used to generate unique block hash values, integrating transaction data into blocks and ensuring that data cannot be tampered with.↵↵In addition, distributed ledger technology is one of  the core technologies of blockchain, sharing data across multiple nodes to maintain a consistent and tamper-proof database. This technology enables secure, transparent, and reliable transactions, making it an indispensable tool for various industries."}]}],"pr":"6c0072e432381ee665d8bd11fc1cbbf46a9b68dc5f4c0ac23517d5232fa30a12"}
