It generates a trusted database with immutable and time-stamped records through cryptographic means, achieving  distributed recording and storage of data information. Blockchain technology adopts decentralized storage to effectively ensure data security, enabling participants to establish consensus on the time sequence and current status of the entire network's transaction records. In addition, blockchain divides the data to be stored in the database into different blocks, with each block linked to the next one through specific information, forming a complete data chain. This structure provides blockchain with high security and transparency, which is beneficial for secure transactions."}]}],"pr":"9078ec8fd850a75797af25cae1a1688a731460478afdcf5ebca5690d4df31ba9"}
