数字人民币十年蝶变：升级2.0，混合架构开辟全球数字货币新路径

Core Viewpoint - The digital renminbi is transitioning from a cash-based model (M0) to a broader coverage including deposits (M1, M2), marking a significant upgrade from version 1.0 to 2.0, which is expected to be fully realized by 2026 [2][3]. Group 1: System Architecture and Operation Mechanism - The digital renminbi 2.0 retains the successful core elements of its pilot phase, particularly the "central bank-commercial institution" dual-layer operational system, which has gained global recognition as a standard for digital currencies [3]. - The People's Bank of China (PBOC) continues to lead the construction and operation of the digital renminbi system, focusing on three core needs: interconnectivity, standardized system construction, and risk prevention mechanisms [4]. - The central bank's digital renminbi system is responsible for lifecycle management, including issuance, exchange, and circulation, as well as providing essential business functions like wallet management and smart contract template management [5]. Group 2: Technological Innovations - The upgrade includes a digital solution based on "account system + currency string + smart contracts," enhancing the digitalization and intelligence of the renminbi's issuance and circulation processes [5]. - The digital renminbi achieves full traceability throughout its lifecycle, with real-time feedback to the central bank regarding transaction data, differing from traditional bank deposits [5]. - The digital renminbi's architecture is a hybrid model that combines centralized ledgers with blockchain technology, allowing for flexible application based on different transaction scenarios [10][11]. Group 3: Cross-Border Applications - The digital renminbi is exploring blockchain applications in various fields, including the establishment of a cross-border payment network through the mBridge initiative, which has processed 4,868 cross-border payment transactions amounting to approximately 477.8 billion yuan [14][15]. - The use of blockchain technology in cross-border payments addresses traditional system shortcomings, such as data privacy and security risks, by allowing local management of data by each participating central bank [15]. - Future expansions of the digital renminbi's cross-border use will focus on technological iterations to broaden access and reduce service costs, facilitating cross-border trade and investment [16].
