Specifically, blockchain technology achieves transparency and immutability by utilizing a decentralized network architecture, with data distributed across numerous computers worldwide. Additionally, blockchain employs consensus mechanisms to ensure  data consistency and security. Furthermore, blockchain technology utilizes cryptography to protect and validate data transmission and access, as well as smart contract programming and operation of data, thereby reducing fraud risks and weaknesses of centralized control. In summary, blockchain technology provides a safer, more transparent, and reliable solution for traditional centralized ledger systems."}]}],"pr":"4c0dba9c721e5460ea8a68efd6ad5808e2c9b9f64aba82b95ecf3bb48bc4b3a8"}
