During the spring meetings of the 2021 International Finance Forum (IFF), Yao Qian, science and technology supervision bureau head at the China Securities Regulatory Commission (CSRC), said that a central bank digital currency (CBDC) could run directly on the Ethereum network or Facebook-backed blockchain payment system Diem when speaking about its operational architecture:
We can imagine that if the central bank’s digital currency runs directly on blockchain networks such as Ethereum and Diem, then the central bank can use their BaaS services to directly provide the central bank’s digital currency to users without using intermediaries.
Overall, Yao outlined seven aspects that have to be considered when researching and developing a CBDC: its technical route, value attributes, operational architecture, interest accrual, distribution, the implementation of smart contracts, and regulatory issues
The official notes that a digital currency cannot be “a simple simulation” of physical money, making a case for creating smart money.
However, he also called attention to the vulnerabilities of smart contracts, claiming that the technology has to mature.
When it comes to regulations, Yao calls for striking the perfect balance between protecting users’ privacy and ensuring compliance with basic anti-money laundering and know-your-customer (KYC) guidelines.
