• available properties:

  • description (free text)
  • divisibility (0-6 decimal places)
  • information (arbitrary byte array, "messages" in NEM)
  • domain name or name space (namespace max. 16, sub-namespace max 64 chars)
  • mosaic name (is unique per domain name)
  • mutable quantity (amount in circulation, can be immutable or dynamic)
  • transferability (n: transfer b/w creator & user; y: transfer b/w all users)
