Research Methodology

The tracker organises publicly available information about central bank digital currency initiatives so readers can compare broad stages and follow meaningful changes. It is a research aid, not an official registry.

Sources may include official central bank, government, legislative, programme, technical, academic, and reputable reporting materials. We seek primary material where available, compare significant claims, record source links, and avoid treating a single unverified statement as conclusive.

Labels such as Research, Proof of concept, Pilot, Launched, and Cancelled are editorial classifications based on the available evidence. They simplify different national terminology and should not be read as legal or official designations.

When sources disagree, the conflict may be noted or the most authoritative and recent evidence may be used with appropriate caution. Historical changes are recorded when the underlying information is available; a missing historical record does not mean that no earlier change occurred.

Coverage, timing, translations, source accessibility, and changing programme language create limitations. Records are updated as information is reviewed, without promising a fixed schedule. Readers can report an error or outdated item at info@cbdc.ac.
