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.

Abstract: Techniques are described for anonymity in private-permissioned, distributed ledger networks. A transaction application is implemented by a mediating member of a private-permissioned, distributed ledger network. The mediating member may utilize the transaction application to execute network transactions with respect to the distributed ledger network. In the network transactions, a surrogate member implements or otherwise facilitates the network transaction on behalf of, or with respect to, a participant, in the context of a plurality of related network transactions being mediated by the mediating member for a plurality of participants. In this way, the mediation may be conducted anonymously, while still utilizing the features of the private-permissioned, distributed ledger network.
