Problems solved by technology

However, because there may be differences of opinion or interest disputes among endorsers, if the identity of the endorsement node is leaked, it may lead to conflicts in the alliance chain. The user identity privacy protection of both parties to the transaction is required, and the identity anonymization protection of the transaction endorsement user is also required

There has been a lot of research and application on the protection of user privacy for both parties in the alliance chain, but there is still a huge research gap in the anonymization of transaction endorsement users
