Abstract

Methods, systems, and computer-readable storage media for notarized communication between platform systems is provided. A first data object is notarized by storing a first root hash value at a blockchain network. 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. A subscription for the first platform system is established to provide notification events in relation to a second data object. The first root hash value comprises an object reference to a second root hash value for the second data object. A notification event is sent for the second data object to the first platform system, comprising a third root hash value of a third data object associated with the second data object. The third data objects is notarized at the blockchain network by the second platform system through a second notarization interface.
