This disclosure describes techniques that include use of a distributed ledger to arrange for and/or initiate provisioning of network services, and also to validate payment for such network services. In one example, this disclosure describes a method that includes modifying, by a computing system, a distributed ledger maintained by a consensus network to implement a smart contract that is configured to generate, in response to receiving a request for network services, a provisioning request; receiving the provisioning request, by the computing system and from a computing device on the consensus network that is executing the smart contract, wherein the provisioning request includes information describing requested network services; and provisioning, by the computing system and based on the information describing the requested network services, network services.
