Abstract

In a hosted computing environment a web server 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 proposes adding the blockchain block to a private blockchain and receives an indication of consensus A block validator adds the blockchain block to the private blockchain responsive to consensus.
