Blind Box
The Blind Box Module is an incentive mechanism that rewards users with guaranteed-prize blind boxes based on their trading activity.
All blind box rewards are funded by the platform’s accumulated transaction fees, forming a transparent and sustainable reward pool.
1. Overview
A Blind Box is a reward unit that users automatically receive when completing eligible trades on the platform. Each blind box can be opened immediately and always yields a prize, with no limit on the number of blind boxes a user may obtain.
Key characteristics:
100% win rate (no empty boxes)
No participation limit
Rewards sourced exclusively from the platform fee pool
Deterministic eligibility, randomized reward amount
2. Reward Funding Source
All blind box rewards are distributed from a Fee Reward Pool, which is funded by:
Platform trading fees
Other protocol-defined fee sources (if applicable)
The reward pool balance is continuously updated and auditable.
3. Eligibility Rules
Blind boxes are granted based on the TBC value of a single transaction.
3.1 Ordinary Blind Box
A user receives an Ordinary Blind Box when:
Single transaction amount ≥ 10 TBC
Reward characteristics:
Maximum reward: 50 TBC
Reward amount is randomly determined within the allowed range
Guaranteed to yield a non-zero reward
3.2 Advanced Blind Box
A user receives an Advanced Blind Box when:
Single transaction amount ≥ 100 TBC
Reward characteristics:
Maximum reward: 100 TBC
Higher expected reward compared to ordinary blind boxes
Guaranteed to yield a non-zero reward
3.3 Upgrade Logic
If a transaction qualifies for an Advanced Blind Box, the user will receive the advanced version only. Ordinary and advanced blind boxes are not stacked for the same transaction.
4. Reward Distribution
Each eligible transaction generates one blind box
Blind boxes can be opened immediately upon issuance
Reward amounts are determined by a randomized algorithm bounded by:
Blind box type
Current reward pool balance
All rewards are denominated and distributed in TBC.
5. Probability and Fairness
100% prize probability for every blind box
No negative or zero-value outcomes
Reward randomness is generated using protocol-defined entropy sources
Reward calculation logic is publicly verifiable
6. Limits and Constraints
Maximum reward (Ordinary)
50 TBC
Maximum reward (Advanced)
100 TBC
Minimum transaction
10 TBC
Claim frequency
Unlimited
Reward asset
TBC
If the reward pool balance is insufficient to cover the maximum reward:
The protocol will cap rewards based on the available balance
Blind box issuance may be temporarily paused if necessary
7. Anti-Abuse Measures
To ensure fairness and sustainability, the Blind Box Module includes:
Single-transaction qualification checks
Fee-source isolation (only platform fees are used)
Reentrancy and double-claim protection
Deterministic transaction-to-reward mapping
The protocol may apply additional safeguards against wash trading or abusive behaviors.
8. Use Cases
Typical use cases include:
Incentivizing trading volume
Rewarding high-value transactions
Promoting sustained platform usage
Redistributing platform revenue to users
9. Risk Disclosure
Reward amounts may fluctuate depending on pool balance
Large reward payouts may temporarily reduce pool availability
The platform does not guarantee expected value per transaction
10. Summary
The Blind Box Module provides a simple, fair, and incentive-aligned reward mechanism with:
Guaranteed rewards
Clear eligibility thresholds
Transparent funding sources
Unlimited participation
This module transforms platform trading fees into direct user incentives while preserving protocol sustainability.
