Metadata
Metadata can be used to inform optional properties that define the specific D-ASA implementation.
The D-ASA metadata MAY be set using the OPTIONAL set_asset_metadata
method.
The D-ASA metadata MAY be updated using the OPTIONAL set_asset_metadata
method.
Prospectus
Debt instruments are defined by their prospectus.
The D-ASA can notarize the debt instrument prospectus in the metadata.
The D-ASA prospectus hash (byte[32]
) and prospectus URL (string
) MAY
be set using the OPTIONAL set_asset_metadata
method.
The prospectus hash MUST be computed with SHA-512/256, as defined in NIST FIPS 180-4.
The digests are a single SHA-256 integrity metadata defined in the W3C subresource integrity specification. Details on generating those digests can be found on the MDN Web Docs (only SHA-256 is supported by this specification).
