Abstract: A method and a DL node for processing a transaction in a distributed ledger (DL) network based on policies are described. A request for a transaction including data is received at a DL node from a user device. A first set of one or more DL nodes of the DL network that have characteristics that satisfy one or more policies associated with the data of the transaction are determined. In response to determining that the DL node is one of the set of DL nodes, the transaction is executed at the DL node, and the transaction is inserted as a private transaction in a digital ledger of the DL network causing a second set of one or more DL nodes of the DL network that is different from the first set of DL nodes to access only an identifier of the transaction and not a payload of the transaction.

Abstract: A method by a computing system implementing a service level agreement (SLA) monitoring client to determine whether a SLA fulfillment status reported by a SLA monitoring agent is valid. The method includes verifying a proof of SLA fulfillment status based on manipulation detection codes of measurements, a SLA fulfillment status, and a verification key, determining whether the measurements are valid based on whether the distributed ledger includes measurement attestations having manipulation detection codes matching the manipulation detection codes of the measurements, and determining that the SLA fulfillment status is valid in response to successfully verifying the proof of SLA fulfillment status and determining that the measurements are valid.

Abstract: A method by a network device implementing a first peer of a distributed ledger to provide trusted execution of a smart contract that uses private data accessible to a second peer of the distributed ledger but not accessible to the first peer. The method includes detecting, during execution of the smart contract, a subroutine of the smart contract that uses the private data, providing an identifier of the subroutine and a proving key to the second peer, obtaining a zero-knowledge proof of computation of the subroutine and a public input to a program adapted for a zero-knowledge proving scheme, wherein the zero-knowledge proof was generated by the second peer, and determining whether the zero-knowledge proof is valid using the zero-knowledge proving scheme based on the public input and a verification key.

Abstract: A first network device obtains information about a user device from an identity management device, and registers a user identity attribute request. The first network device commits to a distributed ledger, a first transaction comprising the user identity attribute request. One or more second network devices receive the first transaction; receive from a user device related to the first transaction, at least a user identity attribute and a proof; receive data from an identity management device; verify validity of the proof based on the data received from the identity management device, and commit to the distributed ledger a second transaction comprising a list of user identity attributes and integrity validation data. The first network device further receives second transactions each second transaction comprising the list of user identity attributes and the integrity validation data. The first network device verifies the list of user identity attributes comprised in the second transactions.

Abstract: An unmanned aerial vehicle, UAV is controlled based on communication via at least two mobile communication networks. Before takeoff, the UAV receives position data describing starting and destination points. A flight plan is set up from the starting point to the destination point by obtaining information about service coverage provided by the two mobile communication networks in a volume between the starting and destination points. A path to be followed by the UAV is calculated at least based on the obtained information. The path defines a restriction volume within which the UAV is allowed to fly from the starting point to the destination point. The path is calculated on the further basis of at least one switching criterion for changing from a communicative connection between the UAV and the first mobile communication network to a communicative connection between the UAV and the second mobile communication network.

Abstract: A method for partial execution of a transaction in a distributed ledger (DL) network. —Execution of a transaction is requested. —First results of a first execution of the transaction and subroutine information for the transaction are received. An execution plan for executing one or more subroutines of the transaction is determined based on the subroutine information. Execution of the transaction by a second DL node of a second participant is requested. —Second results of a second execution of the transaction at the second DL node are received; and validation of the transaction is performed based on bundled results that include the first results and the second results.
