A guest presentation at the Hyperledger Telecom Special Interest Group on April 7, 2022 featuring Francesc Wilhelmi Roca, Postdoctoral researcher at CTTC speaking about the Integration of blockchain and O-RAN to enable the Network-as-a-Service paradigm in Beyond 5G.

Resource sharing is expected to boost economic sustainability Beyond 5G (B5G) networks thanks to the introduction of trends like network virtualization and network slicing. However, enablers for truly shifting to an economy of sharing remain unexplored. In particular, resource sharing is currently tied to slow bureaucratic procedures (relying on trusted third parties) that lack the flexibility to provide ready-to-deploy functionalities and incur high operational costs. In this regard, blockchain technology emerges as a promising solution to replace traditional trust with programmable and scientific trust. Such a programmable trust will enable economically-driven management of the network, based on automatic transactions and self-executing smart contracts, where network providers operate from the cloud, to trade resources, as-a-service. To favor the integration of blockchain technologies into next-generation virtualized networks, we propose extending the baseline O-RAN architecture by introducing the programmable trust concept. The adoption of blockchain technology is expected to foster trustworthiness, automation, and an economically driven management of next-generation networks.
