Caixin: The development of digital yuan smart contracts supports fully Turing-complete languages such as Ethereum's Solidity

According to Caixin, a technical expert familiar with digital RMB revealed that the digital RMB is based on an account system smart contract, which is fundamentally similar to smart contracts on public chains; both are "condition-triggered automatic execution codes," with the distinction being whether they possess full Turing completeness.

The smart contracts of digital RMB based on the account system are considered restricted Turing complete, with programming strictly limited to the template scripts permitted by the central bank, supporting only preset, simple condition-triggered functions. This design is primarily driven by considerations of security and risk control. The development of digital RMB smart contracts supports various programming languages, including Ethereum's Solidity and other fully Turing complete languages, so there are no technical issues. However, the core challenge lies in how to design a standard access and auditing mechanism that can be accepted by the financial system.
