Claim 17:
18. The system of claim 16, wherein the computer-readable storage device includes further instructions, which when executed by the computing device cause the computing device to perform operations comprising:
establishing a chain of notarized root hashes at the blockchain network, the chain including the first root hash value and a fourth root hash value to provide tracking of versions of a first document at the blockchain network,
wherein the first root hash value is notarized in response to a transaction request received through a first notarization interface instantiated at a first platform system, and
wherein the transaction request comprises as input the fourth root hash value, the fourth root hash value being stored at the blockchain network, wherein the first root hash value includes a second notarization reference to the fourth root hash value to define that the first data object is a subsequent version of a fourth data object associated with the fourth root hash value,
wherein the first document is generated at the first platform system in relation to a second document generated at the second platform system, wherein the first data object and the fourth data object are different versions of the first document, and the second data object and the third data object are different versions of the second document.
