Abstract: In one embodiment, a service configured to execute on trusted participant devices authenticates network service devices each having identifying information and one or more offered services, and creates an entry into a secure digital ledger for each authenticated network service device and associated offered services, each entry based on the identifying information and the one or more offered services for a corresponding network service device. Upon receiving an advertisement for an advertised service from an advertising device attached to a given trusted participant device, the service then requests and may receive an authentic ledger entry from the secure digital ledger for the advertised service. In response to either validating or failing to validate authenticity of the advertised service based on the authentic ledger entry, registration at the given trusted participant device of the advertised service for the received advertisement from the advertising device may either be permitted or denied, respectively.
