The Current Reward / KGH NFT / yr represents the anticipated validator rewards per staked KGH NFT for the validator at this time. It can be calculated as follows:
To break it down:
1. Yearly Validator Rewards: This can be calculated using the formula:
2. Reward Boost %: Calculated as:
where:
represents the reward boost percentage for a validator .
is the total number of KGH NFTs staked on validator .
The reward per staked KGH NFT decreases as more KGH NFTs are staked with a validator, while the staking reward grows with the amount of KRO tokens staked.
Example Calculation:
Consider the example values shown in the image above:
Output Submission Probability: 36.64%
Number of KGH NFTs Staked: 887
Validator Reward Boost Percentage: 58.34%
Using these values:
Yearly Expected Validator Rewards:
Reward Boosted Amount:
After Commission (10%):
Current Reward per KGH NFT per Year:
This is an approximate value, as the actual calculation uses non-rounded numbers, which leads to slight differences in the example result.
Kroma operates as an Optimistic Rollup, meaning each submitted output is finalized after a 7-day period. Rewards are distributed only once the validator you’ve staked with receives its reward from an output that is successfully finalized.
This reward distribution process happens hourly but is conditional. Rewards are applied only when the validator has an output finalized within that specific hourly window. As a result, rewards may not be distributed every hour and, in some cases, might not appear for several days if the validator hasn’t had a finalized output. This timing ensures that rewards are accurately applied based on confirmed, finalized outputs.
