Asset Descriptor v1.0

Abstract

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.

General notes

Asset meta is a byte buffer associated with the asset and stored on chain.

Asset metadata should be an UTF-8 string
Asset m etadata should be serialized as a simple name=value set of pairs, delimited with ;
The keyN=valueN; sequence must be preceded with STD: 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

Asset metadata has 2 groups of properties:

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.

Standard properties, mandatory

SCHEMA_VER= metadata schema version, currently must be 1
N= human-readable asset name, for example Beam Coin
SN= human-readable short name/asset code, for example BEAM
UN= human-readable asset unit name, for example Beam
NTHUN= human-readable smallest asset unit name (nth-unit name), for example Groth
