Offline signature refers to the process where the signer signs the transaction information first without knowing the specific transaction content, and then stores the signed information in the blockchain. When verifying a transaction, the blockchain system retrieves the signature and conducts verification. This process can support multiple sessions because in each session, the signer can sign different transaction information. This enables the blockchain system to ensure the security and integrity of the transactions even without knowing the specific transaction content. The use of multiple sessions also makes the blockchain system more flexible and able to meet the needs in different scenarios."}]}],"pr":"08577eb69debdc634ebebc11049cd954f362a2b27ec54dad0528fbb0decf38c3"}
