Abstract

The embodiment of the invention discloses a privacy transaction processing method and device, electronic equipment and a medium, and relates to the technical field of block chains. According to the specific implementation scheme, the method includes obtaining a to-be-executed business transaction request; if the business transaction request belongs to a private business transaction request, acquiring a corresponding private key, wherein the privacy key is an organization key of a privacy organization to which the privacy business transaction request belongs; decrypting the private business transaction request according to the private key, and executing the decrypted private business transaction request to generate private business transaction data, wherein the privacy business transaction data at least comprises associated information of privacy content data and a privacy business transaction request; and storing the private business transaction data in a block chain, and storing the private content data locally. Through the technical scheme of the embodiment of the invention, the private transaction can be executed in a block chain network with low cost, high security and high flexibility.

Description

technical field [0001] The present application relates to computer technology, specifically to blockchain technology, and in particular to a privacy transaction processing method, device, electronic device and medium. Background technique [0002] Traditional distributed computing environments can handle single points of failure, but usually cannot handle malicious behaviors. Malicious behavior of any node will make the entire distributed computing environment unavailable. The development of blockchain technology solves this problem and realizes the need for secure interaction in an untrusted distributed computing environment. [0003] Usually, in the distributed computing environment built by blockchain technology, data is public. However, in some occasions, data disclosure is acceptable, but in some occasions, there is also a need to protect data privacy. Contents of the invention [0004] Embodiments of the present application provide a privacy transaction processing ...
