数字人民币（e-CNY）是由中国人民银行发行的法定数字货币，是人民币的数字化形式。它与纸币和硬币等价，具有法偿性，任何单位和个人不得拒收。数字人民币采用“双层运营”模式：央行向指定的商业银行等运营机构发行数字人民币，再由这些机构向公众兑换和提供服务。其核心技术基于分布式账本、加密算法和智能合约，既保障了交易的安全性和隐私性，又支持可控匿名——即小额交易可匿名，大额交易可追溯。数字人民币不依赖银行账户，支持“双离线支付”，即使在没有网络的情况下，两部手机碰一碰也能完成转账。它旨在提升支付效率、降低现金管理成本，并增强货币政策的精准性和金融普惠性。目前，数字人民币已在多个城市开展试点，涵盖交通、零售、政务等多个场景，但尚未全面推广。需要注意的是，数字人民币不同于比特币等加密货币，也不同于支付宝、微信支付等第三方支付工具——前者是去中心化的虚拟资产，后者只是电子钱包，而数字人民币本身就是法定货币。
Digital RMB (e-CNY) is the official digital currency issued by the People’s Bank of China (PBOC), representing a digital form of the Chinese yuan. It holds the same legal tender status as physical banknotes and coins, meaning it must be accepted by all individuals and institutions. The e-CNY operates under a two-tier system: the central bank issues it to authorized commercial banks and other designated institutions, which then distribute it to the public. Built on technologies such as distributed ledgers, cryptographic algorithms, and smart contracts, e-CNY ensures transaction security and privacy while supporting ‘controllable anonymity’—small transactions can remain anonymous, while large ones are traceable. Unlike traditional electronic payments, e-CNY does not require a bank account and enables ‘dual offline payments,’ allowing transfers between two devices even without internet connectivity. Its goals include improving payment efficiency, reducing cash handling costs, enhancing the precision of monetary policy, and promoting financial inclusion. Currently, e-CNY is being piloted in multiple Chinese cities across scenarios like transportation, retail, and government services, though nationwide rollout has not yet occurred. Importantly, e-CNY differs from cryptocurrencies like Bitcoin (which are decentralized assets) and from third-party payment platforms like Alipay or WeChat Pay (which are merely digital wallets)—e-CNY itself is sovereign legal tender.
