The core breakthrough of the 2022 revision to the UCC in the U.S.: officially recognizing 'control' as equivalent to 'possession.' The traditional commercial law framework was designed for paper contracts and physical assets, but it’s now struggling to keep up with electronic agreements, digital currencies, and on-chain assets. This revision introduces the concept of 'Controllable Electronic Records' (CER), allowing security interests to be perfected through control rather than traditional registration and public notice. For DeFi and digital assets, this serves as the legal foundation for institutionalized security. The most critical change is the restructuring of the currency classification system—not simply dividing it by 'legal tender or not,' but adapting rules based on functionality, transferability, and control methods. If Chinese commercial law doesn’t keep up with digital evolution, it might take decades to close this gap.
