Caixin: Digital RMB smart contract development supports fully Turing-complete languages such as Ethereum's Solidity

The digital renminbi's smart contracts are based on an account system, featuring limited Turing completeness, primarily supporting simple condition-triggered functions to enhance security. Although they can support multiple programming languages, designing an access and auditing mechanism that meets the standards accepted by the financial system is the main challenge.

Mars Finance reports that according to Caixin, a technical expert familiar with digital renminbi revealed that the digital renminbi based on an account system with smart contracts is fundamentally similar to smart contracts on public blockchains—both are “condition-triggered automatic execution codes.” The difference lies in whether they have full Turing completeness. The smart contracts of the digital renminbi based on an account system are a restricted form of Turing completeness, with programming strictly limited to template scripts approved by the central bank, supporting only preset, simple condition-triggered functions. This design is primarily for security and risk control considerations. The development of digital renminbi smart contracts supports multiple programming languages, including fully Turing-complete languages like Ethereum’s Solidity, so technically it is not an issue. However, the core challenge is how to design a set of standard access and auditing mechanisms that can be accepted by the financial system.
