Divergent paths in digital currency development: a comparative study of China and the United States with a global perspective

The United States and China exhibit markedly different development paths in digital assets and blockchain technology. The US relies on market-driven approaches, with the private sector promoting stablecoin innovation to strengthen the dollar’s global position, while China adopts a government-led approach, implementing centralized systems such as consortium chains and the digital yuan (e-CNY), emphasizing financial security and regulation. These divergent paths reflect fundamental institutional differences: American distrust of centralized institutions has fostered distributed ledger development, while China mitigates risks through government leadership. Currently, the digital yuan faces adoption challenges due to insufficient enthusiasm from commercial banks. We propose implementing a “dynamic reserve mechanism” to incentivize circulation and enhance privacy protection to address user concerns. The private sector should participate more actively in innovation, and we recommend establishing AI-supported “dynamic regulatory sandboxes” or “smart regulatory gateways” based on smart contracts to better balance innovation and regulatory needs. To address inflation and depegging risks of stablecoins, we recommend moving beyond fiat currency pegging to explore new models anchored to consumer goods, such as a “BigMac Coin.”
