Specifically, once the information is verified and added to the blockchain, it is permanently stored. Unless more than 51% of the nodes in the system are controlled simultaneously,  modifications to the database on a single node are ineffective. This means that the data stability and reliability of the blockchain are extremely high. In addition, the blockchain adopts technologies such as peer-to-peer transmission and Merkle tree structure to ensure the security, transparency, and traceability of the data. In summary, blockchain technology ensures the authenticity and credibility of data through various means, preventing tampering and counterfeit information."}]}],"pr":"ef50870c59828cc9e1e00ad0bfa074728c327d7bd87ca34688d1ba75c1c9834c"}
