    Abstract: In a hosted computing environment having at least one processor and a memory therein, a web server in the hosted computing environment receives a document history graph. The web server performs a hash function, providing the document history graph as input to the hash function, the hash function providing a hash value as output. A blockchain services interface in the hosted computing environment generates a blockchain block that includes the hash value in a block payload hash field and the document history graph in a block payload field in the blockchain block. A blockchain consensus manager in the hosted computing environment proposes adding the blockchain block to a private blockchain. The blockchain consensus manager receives an indication of consensus among authorized blockchain nodes in the private blockchain to add the blockchain block to the private blockchain. Finally, a block validator in the hosted computing environment adds the blockchain block to the private blockchain responsive to receiving the indication of consensus.
