Mosaic definition transaction

Mosaic definition transaction

Before a mosaic can be created or transferred, a corresponding definition of the mosaic has to be created and published to the network.

• This is done via a mosaic definition transaction.

• Following parameters are required:
  • Name
    • Name of the mosaic, up to a size limit of 64 characters; must be unique under the domain name.
  • Namespace name
    • To be able to create a mosaic definition, an account must rent at least one root namespace which the mosaic definition can then refer to.
  • Mosaic properties
    • supply mutable: The creator can choose between a definition that allows a mosaic supply change at a later point or a immutable supply. In the first case the creator is only allowed to decrease the supply within the limits of mosaics owned.
    • transferability: The creator can choose if the mosaic can be transferred to and from arbitrary accounts, or only allowing itself to be the recipient once transferred for the first time.
    • levymutable
    • divisibility: Determines up to what decimal place the mosaic can be divided. Divisibility of 3 means that a mosaic can be divided into smallest parts of 0.001 mosaics. The divisibility must be in the range of 0 and 6.
    • duration: The number of confirmed blocks we would like to rent our namespace for. Should be inferior or equal to namespace duration.
