Abstract: Systems and methods are provided for use in monitoring decentralized data structures including identity attributes, through tokenization of the attributes. One example computer-implemented method includes receiving a request associated with a digital identity including multiple attributes and, for each of the attributes in the request, generating a token specific to the attribute, searching for the generated token in a network graph having multiple stored tokens, and identifying one of the multiple stored tokens as a match to the generated token. The computer-implemented method then further includes, for each of the attributes in the request, retrieving additional ones of the multiple stored tokens linked to the identified one of the stored tokens, comparing the retrieved tokens to the generated token, and promoting the request for further action, in response to at least one of the retrieved tokens being inconsistent with the generated token.
