Distributed Ledger Technologies (DLTs) and Blockchain

Distributed Ledger Technologies (DLTs) and Blockchain are becoming increasingly relevant for the development of 6G networks, particularly in terms of security and privacy. In this chapter, we explore the fundamental concepts of DLT and Blockchain and how they can be applied to 6G networks. By the end of this chapter, readers should have a better understanding of the role of DLT and Blockchain in enhancing security and privacy in 6G networks, as well as the potential threats to their use. Key topics covered include the basis of DLT and Blockchain in 6G networks, their specific applications in network security and privacy, and the potential vulnerabilities and threat landscape of Blockchain technology.
