Campaign

A brand campaign is created in the Brand Market to offer ENDU token payment for mining a user brand.

A campaign is identified by the brand memo and owner (or payer) so the same memo can be paid by multiple payers via multiple brand campaigns.

A campaign has:

• memo: the UTF-8 text to mine

• payer: the owner of the campaign

• fund: ENDU tokens amount locked by the owner to pay miners

• payRate: payment rate for each successful mining transaction

• expiration: expiration date

The campaign is deactivated when either:

• the expiration is reached

• all the fund is spent

An expired campaign can be manually deactivated by its owner and all the remaining locked ENDU is refunded.

An unexpired campaign can only be upgraded to either:

• increase the pay rate

• extending the expiration

• add more fund
