Technologies for facilitating APIs for microservices associated with a communications network are disclosed. An example method includes receiving a request to a target API exposed by an API platform, and invoking a combination of API governance modules corresponding to the target API and selected from API governance modules implemented remotely from the API platform, to map the request to microservices. The microservices include internal microservice(s) maintained within the communications network and external microservice(s) maintained externally to the communications network. The method also includes applying API governance policies indicated by the combination of API governance modules to validate interactions with the external microservice(s) based on the request and generating and sending a response to the request.

Systems and methods for using a distributed ledger to maintain a blockchain are provided. An example method includes receiving transaction information associated with a transaction involving a service provider and a consumer, the transaction information including transaction terms and conditions, receiving an indication, the indication indicating that the consumer assented to the terms and conditions, creating a transaction record, the transaction record including a transaction identifier, a consumer identifier of the consumer, the transaction terms and conditions, and the indication, creating a block in a blockchain managed by a blockchain as a service (BaaS) system, and storing the transaction record in the block.

Digital document and network management (DDMS) system includes digitizing a document into a standard digital format, and storing the digitized document in an authoritative CTR governance database. The DDMS system also includes organizing a plurality of technical requirements extracted from the digitized contract within the authoritative CTR governance database, and linking a plurality of network function test cases to the plurality of technical requirements. Furthermore, the DDMS system includes storing a plurality of results in the authoritative CTR governance database.

Edge blockchain authentication for communications networks is disclosed. By using a blockchain approach instead of a conventional network function (NF) authentication approach, authentication for applications and services can be performed at an authenticating data center (ADC) without the need to involve the regional data center (RDC) and/or the national data center (NDC). Application Programming Interfaces (APIs) for individual NFs may not be needed. Once authenticated via the blockchain, legitimate transactions can interact with NFs.
