Security, Privacy and Trust of Distributed Ledgers Technology

This chapter presents the Blockchain distributed ledger technology (DLT), to provide decentralized technological infrastructure and protocols. It provides a platform that helps all the stakeholders connect to the decentralized system while ensuring privacy, security, verification, and validation. It, most importantly, provides an immutable and traceable way across decentralized systems. This chapter presents the introduction, technologies, theories, and evaluation of DLT and Blockchain technologies. It offers valuable discussion while covering essential topics concerning the implementation of DLT and Blockchain technologies concerning CAP Theorem, security and privacy issues of DLT. The chapter also highlights the challenges and problems associated with these areas. While covering the theoretical concept, the chapter also provides DLT implementation frameworks and typical blockchain systems and technologies. The contributions highlight the challenges and issues while addressing security, scalability, and decentralization; It will help the reader gain insight into these technologies that may help them warrant further research in these areas.
