The Software Defined Networking (SDN) paradigm has the potential to improve the operation and efficiency of the global Internet. In recent times, SDN has been extensively adopted in data centres and business networks. Recently, more research is being carried out to find solutions to the problems caused by the continually increasing complexities of the SDN. Issues regarding the lack of transparency between SDN domains impact security, so peer authentication is required. Peer authentication remains a critical issue. SDN domains are linked by the routing protocol Border Gateway Protocol Version 4 (BGP4). To improve the transparency of BGP4 transactions, this paper proposed a Blockchain-based BGP4 Orchestration (BBO) framework that utilises an Internet number resource authority and trustworthy management entity. BBO provides an origin advertisement source and has been found to outperform Resource Public Key Infrastructure (RPKI) in terms of securing origin advertisement and establishing a required setting for the resource repository. This research work ensures sufficient deployment incentives for SDN based federations.
