Abstract
Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for managing sensitive data elements stored in a blockchain network. One of the methods includes receiving a request from a client device to perform a modification to a watch list that is stored in the blockchain network. The watch list includes one or more sensitive data elements. The blockchain network node determines whether the client device is authorized to modify the watch list based on a digital signature in the request. In response to determining that the client device is authorized to modify the watch list, a consensus procedure is performed on the request within the blockchain network. After a consensus is achieved, the blockchain network node updates the watch list based on the modification to the watch list.
