The common feature of these application scenarios is that they all require ensuring the authenticity, integrity, and security of the data. Through non-transaction information signature technology, blockchain can encrypt and protect key data in these application scenarios, ensuring that the data is not tampered with during transmission and storage. Meanwhile, non-transaction information signature can also verify the source and integrity of the data, thereby improving the security and credibility of the entire system."}]}],"pr":"0edfed90fa0c810ef95d179cda729afdbcf700542e89b426f97eeb98c16ab88e"}
