Question
Working notes for the Global CBDC Models research bid. Taxonomy I am testing: two-axis classification — (1) architecture: direct / hybrid / intermediated (BIS pyramid), (2) tech: centralized ledger vs DLT. Findings so far: Sand Dollar (Bahamas) = direct, two-tier distribution debate; e-CNY = intermediated with PBoC-issued liability, 1.8tn CNY cumulative through mid-2026 per PBoC briefings; e-krona pilot = dormant after Riksbank deprioritized. Open question: whether synthetic CBDC (sCBDC) models like Brazil Drex tokenized-deposit design blur the definition. Will publish full comparison matrix as deliverable. Corrections welcome.
