The BOJ CBDC Roadmap: From Proof-of-Concept to Pilot Framework (Japan FinTech Observer)
A Japan FinTech Observer article by Norbert Gehrke describes the Bank of Japan central bank digital currency (CBDC) project’s shift from the proof-of-concept phase to pilot planning, restructuring governance from seven Working Groups into three Discussion Groups focused on architecture, new technology, and ecosystem design. The piece describes how work will now concentrate on defining “minimum necessary functions,” stress‑testing an online retail ledger at 50,000 transactions per second, and managing scaling limits of techniques such as record splitting. It highlights operational bottlenecks along a four‑step user journey (onboarding, charging, payments, and value‑added services), emphasizing frictions in know‑your‑customer synchronization, liquidity auto‑charge logic, and dispute handling. A core policy issue is standardizing interfaces between the central ledger and heterogeneous private money formats to maintain universal access and “singleness of money” while enabling tokenized deposits and programmability. The unresolved questions concern interface standards and privacy‑preserving data use. [Japan FinTech Observer]
BTW if you want to see a complete database of my DFC-related posts going back years, including many that didn’t make the Daily Digest cut, click here.
FYI I produce a monthly digest of digital fiat currency (DFC) developments exclusively for the official sector (e.g., central banks, ministries of finance and international financial institution (e.g., the BIS, IMF, OECD, World Bank)) plus academics and firms that are active in the DFC space (commercial banks, technology providers, consultants, etc.). (DFCs include central bank digital currency (CBDC), stablecoins and tokenized deposits.) It goes out via email on the first business day of every month, and if you’re interested in being on the mailing list, please email me at john@kiffmeister.com.
