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.

Zero-knowledge service level agreement (SLA) monitoring

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.

Policy-aware distributed ledger networks

A method and device for registering an embedded Universal Integrated Circuit Card (eUICC) for a device and a method and device for controlling authorization of operation of a device being equipped with an eUICC. In an aspect, a method of a service node of registering an eUICC for a device is provided. The method comprises receiving information specifying ownership of the device and an identifier of the device, receiving an identifier of the eUICC and an identifier of the device, and storing the received information, wherein ownership of the device and the identifier of the eUICC being arranged in the device is registered with the service node.
