Specifically, firstly, during the transaction process, blockchain technology uses encryption algorithms to encrypt transaction data, making the data on the chain only decryptable and not directly viewable. Secondly, zero-knowledge proof allows the chain code end to prove the  compliance of the transaction process under all encrypted transaction data, thereby avoiding the risk of privacy leaks. In addition, the collaborative improvement solution based on IPFS (InterPlanetary File System) solves the inconsistency problem that may exist between on-chain and off-chain data under encryption, further improving the security and privacy of the blockchain system."}]}],"pr":"85007f3a4f99282ba1e93482e158c63ae9a19a25427999673b2bb676ece078cd"}
