The Bank for International Settlements Innovation Hub has presented Project Tamga, led by its Hong Kong Centre, exploring how regulatory proofs such as licences and attestations could be validated across jurisdictions through a common verification and discovery mechanism without creating new registry systems. The project concept reuses established internet infrastructure and security standards, including DNS, HTTPS and standardised well-known web paths, as a trust layer for supervisory and compliance use cases. It centres on “trust metadata”, a minimal structured dataset for proof verification that could include cryptographic elements such as public keys and certificate chains, made automatically discoverable on the issuer’s own domain so verifiers can retrieve it directly and validate proofs without central registries, intermediaries or blockchains. The BIS notes that embedding verifiable regulatory proofs into digital workflows could support real-time checks of compliance conditions such as licensing status, reporting obligations and supervisory limits, while preserving sovereignty and confidentiality requirements.

Bank for International Settlements Innovation Hub outlines Project Tamga for internet-based cross-border verification of regulatory proofs
The Bank for International Settlements Innovation Hub's Project Tamga, led by the Hong Kong Centre, explores validating regulatory proofs like licenses across jurisdictions using existing internet infrastructure and security standards without new registry systems. The project employs "trust metadata" for proof verification, enabling real-time compliance checks while maintaining sovereignty and confidentiality.
