摘要： A computer-implemented method for revoking access to a first network, wherein the first network comprises a set of bridging nodes and a set of devices controllable by one or more of the set of bridging nodes, wherein each bridging node is also a respective node of a blockchain network, and wherein each bridging node and device is associated with a respective certificate granting access to the first network; the method being performed by a registration authority and comprising: obtaining an alert transaction, the alert transaction being a blockchain transaction and comprising a first output, the first output comprising an alert message identifying one or more bridging nodes and/or one or more devices; and revoking access to the first network by the identified one or more bridging nodes and/or one or more devices by revoking the respective certificate of the identified one or more bridging nodes and/or one or more devices.
