1. A method comprising:
at a network configured to coordinate resource sharing of disaggregated radio access network (RAN) components or entities of a disaggregated RAN architecture with use of a distributed ledger which is provided via the network for authentication and authorization of the disaggregated RAN components or entities,
registering with the distributed ledger a first RAN entity of a first vendor and a second RAN entity of a second vendor;
obtaining a request from the first RAN entity of the first vendor to use resources of the second RAN entity of the second vendor;
in response to the request, validating with the distributed ledger whether the first RAN entity of the first vendor and the second RAN entity of the second vendor have been registered with the distributed ledger and are to share the resources; and
based on the validating, providing to the second RAN entity of the second vendor a notification that the first RAN entity of the first vendor is to be permitted to share the resources of the second RAN entity of the second vendor.
