Central Bank Digital Currency (CBDC) is a digital version of domestic currency with a unit of account equivalent to its domestic currency. Blockchain or Distributed Ledger technology (DLT) can be used to implement CBDC to execute and settle peer-to-peer transactions. With the emergence of private money, such as cryptocurrencies and stablecoins, and the growing use of digital payments to lessen the global pandemic spread, CBDC is an active research area among central banks worldwide. Many central banks started their CBDC projects by building DLT proofs of concept (PoCs) to replicate wholesale payment systems and expand their investigation into other use cases, such as delivery versus Payment (DvP) and cross-border remittance. Many large economies like the United States have projects exploring CBDC. The People's Bank of China (PBoC), China Central Bank, has already started a pilot testing of their digital retail currency. This paper discusses the application of blockchain for CBDC by presenting CBDC projects by central banks. Moreover, this paper analyses issues, identify challenges and discusses future works in this rapidly evolving field.
中央银行数字货币（CBDC）是本国货币的数字版本，其记账单位等同于本国货币。区块链或分布式账本技术（DLT）可用于实现CBDC，以执行和结算点对点交易。随着加密货币和稳定币等私人货币的出现，以及为减少全球疫情传播而对数字支付的使用日益增加，CBDC成为全球各国央行积极研究的领域。许多央行通过构建DLT概念验证（PoC）来启动其CBDC项目，以复制批发支付系统，并将其调查扩展到其他用例，如付款交割（DvP）和跨境汇款。许多大型经济体，如美国，都有探索CBDC的项目。中国央行中国人民银行已经开始对其数字零售货币进行试点测试。本文通过介绍各国央行的CBDC项目来探讨区块链在CBDC中的应用。此外，本文分析了相关问题，识别了挑战，并讨论了这个快速发展领域的未来工作。
