Anonymity and Traceability Improvement Techniques for Digital Asset Transactions in Distributed Transaction Consensus Networks

摘要

The present disclosure relates to a method and system for enhancing the anonymity and traceability of a digital asset management system for managing digital asset transactions in a distributed transaction consensus network, using encryption techniques to process transactions. The digital asset management system includes a sender''s digital asset manager and a receiver''s digital asset manager. The sender''s digital asset manager further includes the sender''s digital asset management module and the sender''s transaction node, and the receiver''s digital asset manager further includes the receiver''s digital asset management module and the receiver''s transaction node. In order to increase the anonymity of the transmission transaction between the sender and the receiver, the sender''s digital asset management module is not allowed to access the receiver''s virtual identifier. Thus, the recipient''s digital asset management module generates a token to temporarily replace the recipient''s virtual identifier. To increase anonymity, encrypted labels are generated for each subtransaction to identify subtransactions and their sequences within the same remittance set.
