Reward Program

Reward Programs are configurable campaigns that encourage users to participate in the Provenance Blockchain. Entities interested in creating a Reward Program will supply their new program with funds, set the duration of their program, and provide the participation requirements.

Qualifying Actions and Eligibility Criteria

A Qualifying Action is one or more transactions that a user performs on the Provenance Blockchain that has been listed within the Reward Program. These actions are then evaluated against a set of criteria that are also defined within the Reward Program known as Eligiblity Criteria. Users become participants in the Reward Program by performing a Qualifying Action and meeting all conditions specified by its Eligiblity Criteria.

Claim Period

A Reward Program is split into one or more time intervals known as Claim Periods. Each of these Claim Periods gets an equal portion of the Reward Program Reward Pool known as the Claim Period Reward Pool. Users can participate within these Claim Periods and are rewarded for their actions.

Reward Claim

When a user participates in a Reward Program they are granted one or more shares of the Claim Period Reward Pool. Once theClaim Period ends, the participant will be able to claim their reward by performing a claim transaction. The participant's reward is proportional to their activity compared to everyone else within a Claim Period. Users must claim their rewards before the Reward Program expires. Additionally, users will be limited to max_reward_per_address of the Claim Period Reward Pool.

Rollover

It is possible that not all of the Claim Period Reward Pool will be distributed. This can happen when there is not enough activity, and participants are gated by the max_reward_per_address. The Reward Program will attempt to move these funds into a Rollover Claim Period. A Rollover Claim Period behaves exactly like any other Claim Period, but it is not guaranteed to have an equal portion of the original Reward Program Reward Pool. A Reward Program may run up to max_rollover_claim_periods, but is not guaranteed to run any of them. This is dependent on user activity, program_end_time_max field, and the minimum_rollover_amount field. Currently, the minimum_rollover_amount is set to 10% of the Claim Period Reward Pool.

Refunding

When a Reward Program ends it gives all participants expiration_offset seconds to claim their rewards. After expiration_offset seconds the Reward Program expires and prevents participants from claiming. The unclaimed rewards and any funds still remaining within the Reward Program Reward Pool will be given back to the creator.
