Much attention has been paid to the security of interdomain routing system. It is crucial to achieve the origin validation of Internet resource and multi-domain collaboration. By virtue of the natural attributes of blockchain including decentralization, tamperresistant, and traceability, blockchain technology can act as the basis of Internet resource certification and trust establishment among multiple Internet domains. Firstly, the vulnerabilities of interdomain routing system and the dilemma of existing interdomain security proposals are analyzed including difficulty in deployment, complexity in management, centralized trust mechanism, etc. Secondly, based on the introduction of the basic concept of blockchain, the technical ideals of blockchain-based interdomain security solutions are pointed out, and an up-to-date review of blockchain-based interdomain security solutions is conducted from 3 aspects:interdomain routing authentication, intelligent interdomain management, and DDoS defense and mitigation. Finally, the advantages of blockchain-based interdomain security solutions are summarized and corresponding challenges are analyzed from the perspectives of scalability, deployment, and security, and the development outlook of blockchain technology used in the field of interdomain routing security is highlighted.
