A system for integration and interoperability between disparate distributed server technologies is provided. In particular, the system may provide communications functionality between heterogenous distributed register technology networks. In this regard, the system may establish an interoperability layer between the disparate networks to allow cross-network process flows to be executed. The interoperability layer may comprise one or more network services nodes for each distributed register technology to be integrated by the system. Each network services nodes may act as an event handler for internal processes executed within a given distributed register network and be configured to send and receive data from other network services nodes regarding the execution of such processes. The respective network services may then use the data obtained regarding such internal processes to in turn execute its own processes. In this way, the system may efficiently integrate networks using disparate distributed register technologies.
