Document Type and Number:
WIPO Patent Application WO/2020/233609
Kind Code:
A1
Abstract:
A conditional receipt storage method and node combining the code labeling with the user type. The method may comprise: a first blockchain node receives an encrypted transaction corresponding to a smart subscription, a code of the smart subscription comprising an object marked by an exposure identifier (302); the first blockchain node decrypts the transaction in a trusted execution environment to obtain the code of the smart subscription (304); the first blockchain node executes the code of the smart subscription in the trusted execution environment to obtain receipt data (306); the first blockchain node stores the receipt data so that when a transaction initiator is of a preset user type, the part of the receipt content corresponding to the object marked by the exposure identifier and satisfying a preset condition is stored in a form of plaintext, and the remaining receipt content of the receipt data is stored in a form of ciphertext (308).
