Firstly, blockchain uses encryption algorithms (such as SHA-256) to encrypt transaction data, ensuring the security of data during transmission and storage. Secondly, blockchain  employs anonymous mechanisms, such as mixers and zero-knowledge proof technologies, to mask the identities of the parties involved in the transaction and the transaction amount. Mixers combine multiple transactions into a single set of transactions, making it difficult for external observers to trace the initiator, receiver, and transaction amount. Meanwhile, zero-knowledge proof technologies allow users to prove that they possess certain information without revealing the original data."}]}],"pr":"8d6b9b518e3f28ec84ee4f314cf3af3411ac2dd8f50940d48a4e4d8eb3b94566"}
