A trend in future networks (i.e., beyond 5G and 6G) is the increasing virtualization and disaggregation of networks (i.e., Open Radio Access Network, network function virtulization/software-defined networking, or disaggregated optical networks, among others). This trend leads to a multi-vendor situation appearing in the telco arena (i.e., hardware suppliers, software function providers, vendors, operators) that communications service providers will need to deal with. This multi-stakeholder scenario complicates provisioning and the established relationships among actors based on operation agreements that define the requirements, penalties, and prices that generate a certain level of trust among them. This new disaggregated scenario implies an increment of possibilities and relationships, requiring agreements to be created in a run-time way. As the agreement is generated ad hoc, selecting a provider is a crucial decision, and so, trust and transparency are keys to help with this decis...
