Firstly, distributed ledger technology generates data in a time-sequenced manner, connecting blocks through a chain structure to form an immutable chain-based data structure. Secondly, cryptographic protection ensures the security of the data, allowing only users with the correct keys to access and modify data, thereby preventing data leaks and forgeries. Lastly, consensus algorithms ensure the decentralized characteristics of the blockchain system, with all nodes participating in data verification and generation together, avoiding single-center control."}]}],"pr":"af0ef405bfbb6a81804cdb5fdd330ec633c1d17c6515ecfd6163cae866505089"}
