Abstract: An example operation may include one or more of constructing a transaction proposal and sending the constructed transaction proposal to a plurality of endorsing nodes, by a client application of a computing system, wherein inputs to the transaction proposal are named using a blockchain naming system (BNS), receiving a set of transaction responses from the plurality of endorsing nodes, by the client application of the computing system, the transaction responses each comprising a transaction validation function, assembling the received transaction responses into a transaction, by the client application of the computing system, and sending the transaction to an orderer node for distribution, by the client application of the computing system.

Abstract: An example operation may include one or more of constructing a transaction proposal, by a computing system, wherein inputs to the transaction proposal are named using a blockchain naming system (BNS) that comprises ledger state addressing, oracles for addressing external data values, and user state addressing, the BNS providing a standard mechanism to name all blockchain resources using a universal resource indicator (URI).

Abstract: Provided are methods, apparatus and computer programs for monitoring operational data relating to a sequence of data processing operations in a network of data processing units. In response to specified boundaries for data gathering, operational data is selectively gathered into discrete data partitions for a desired time period, a desired set of processing nodes, and/or a desired set of process executions. A set of event listeners invoke operations of a data gatherer in response to events within a processing sequence and the data gatherer allocates operational data to different ones of a set of discrete logical data containers in response to notifications from the event listeners. The data collection is responsive to system events such as a collection interval expiry to end data collection for a first partition and start data collection for a second partition.
