Abstract
An example operation may include one or more of receiving, by a document validation node, documents from a plurality of document owner nodes over a blockchain network, generating, by the document validation node, commitments for the documents on the blockchain network, deriving, by the document validation node, proofs to verify predicates of the documents, and generating, by the document validation node, a document relationship graph (DRG) based on the commitments and the predicates.
