Item Restricted Should Central Banks Issue Digital Currency?(Saudi Digital Library, 2023-10-01) Alaqeeli, Abdulrahman; Liang, ShiCentral Bank Digital Currency (CBDC) is considered a potential advancement in the evolution of money, offering a more stable unit of account, efficient medium of exchange, and secure value storage. However, despite gaining attention from scholars and practitioners in recent years, plenty of questions on how central banks can effectively develop CBDCs and their potential impact on a country's existing financial system remain uncertain. This paper employs a combination of text mining and systematic review methods to comprehensively analyze academic papers on CBDC. Its aim is to pinpoint key research issues and knowledge gaps that warrant future exploration. We find six primary research themes connected to CBDC, including 1- CBDC issuance 2-CBDC and compatibility, 3- CBDC and monetary policy, 4- CBDC and financial stability, 5- CBDC and payment system 6- CBDC and privacy and security. The findings help provide both overall and in-depth views of the current state of research in digital fiat currency topics, as well as drawing some important implications and suggestions on directions for the future research.21 0Item Restricted Corda to Ethereum Interoperability: the Use Case of Wholesale to Retail CBDC Transfer(Saudi Digital Library, 2023-12-01) Alkahtani, Munera; Vadgama, NikhilThe rapid evolution of blockchain and distributed ledger technologies (DLTs) has shown a new era of digital innovation with profound implications for various industries, particularly in the financial sector. Central to this transformation is the emergence of Central Bank Digital Currencies(CBDCs), representing a pivotal development in modernizing monetary systems. DLT has proven to be the best technology candidate for developing central bank digital currencies (CBDCs) use cases due to its many features, such as transparency and immutability. This dissertation explores the interoperability between two prominent DLTs, Corda and Ethereum, to facilitate the issuance and seamless transfer of CBDCs. The methodology employed in this research revolves around a bridge/router architecture, acting as middleware to bridge between the source DLT (Corda) and the target DLT (Ethereum). The study leverages the Cross-Blockchain Integration Design Decision (CBIDD) framework to systematically select an appropriate interoperability approach. A prototype was implemented using Node.js along with Corda and Ethereum smart contracts, utilizing the native features of Corda, Ethereum, and Web3.js. A preliminary evaluation depicts that the latency is influenced more by the DLs than the bridge components.17 0
