[NCIP 25] Improvement of World Boss Reward System. 25.02.18

NCIP: https://github.com/ipdae/NCIPs/blob/ncip-25/NCIP/ncip-25.md

Abstract

Transition from an admin-controlled reward distribution system to a user-driven claim system where all users can claim rewards according to predefined rules.

Motivation

The manual processing part of the world boss reward system imposes a load on the chain and incurs continuous costs for the development team. We aim to improve this part to create a system that operates more efficiently overall.

Specification

To simplify the process, a new action ClaimWorldBossReward has been added, allowing users to claim rewards using their avatar address.

The plain value is stored in Dictionary format like other actions. The schema is as follows.

{
"type_id": "claim_world_boss_reward", # action type name.
"values": [
AvatarAddress # target avatar address will claim reward.
]
}
Change the season rewards received by users after the season ends from rank-based to a fixed total amount distributed according to contribution (like Adventure Boss).
Instead of distributing rewards all at once after the season ends, allow individual claims over a certain period.
Claim period is available during the 2-week off-season.

Reward Distribution

Reward Processing Rules

Contribution % Calculation Formula

Total damage dealt during the season / Total damage dealt during the season * 100
Calculate Contribution % up to 4 decimal places (minimum 0.0001%).
Determine the quantity of rewards based on the Contribution %, truncating any decimal values.

If the total reward is 1M Rune Fragment 1, 10K Rune Fragment 2, and 1B Crystal, a user with a Contribution % of 0.01% receives 100 Rune Fragment 1, 10 Rune Fragment 2, and 10K Crystal.

Additional Changes

Due to too many perfect scorers in the world boss, change the required scores for A rank and S rank.
As season rewards change from rank-based to contribution-based, fix the ticket purchase price at 1ncg.
Fixed at 1ncg up to the maximum number.

Backward Compatibility

This proposal requires hard-forks for the following reasons:
A new action type claim_world_boss_reward is added, and all nodes need to be updated to interpret the action.
A new sheet type WorldBossContributionRewardSheet is added for reward information.
WorldBossState will be record season's ToTalDamage for calculate each user's contribution.

The changes for the rewards calculation and in the max scores for S rank are super awesome!
It's also great that the distribution is now automated. Great improvements all around!

All the tickets will cost jsut 1 ncg each now?
