The assets are described here
This document's purpose is to specify the asset metadata, to enable 3rd party tools to consume and display the subset of asset-related information in a simple and well-standardized manner.
Asset meta is a byte buffer associated with the asset and stored on chain.
- Asset metadata should be an UTF-8 string
- Asset metadata should be serialized as a simple name=value set of pairs, delimited with
;
- The
keyN=valueN;
sequence must be preceded withSTD:
prefix, there is no need for;
at the sequence end - The total size of the metadata cannot exceed 16 Kbytes (16,384 bytes)
- Every description should be in English
- Standard properties
- Optional properties
WARNING: Both types of properties are immutable and can't be changed after the asset is created. Therefore it is strongly recommended to double-check the values before starting the asset registration.
