Evidence Blind Box Trading Mechanism & Roles
Evidence Blind Box ecosystem relies on the collaborative game theory of multiple roles. To ensure the system's decentralization and censorship resistance, we have designed a refined permission separation and incentive mechanism.
1. Key Ecosystem Roles
- Minter: Evidence Blind Box creator, i.e., the whistleblower.
- Seller: Other users acting as agents to sell the Box.
- Buyer: The user who pays to purchase/auction the Evidence Blind Box.
- Bidder: The user who participates in an auction but fails.
- Completer: Other users (non-Buyer and non-Minter) acting as agents to execute order completion.
- DAO: The highest authority entity for governance, parameter adjustment, blacklist processing, and transaction dispute arbitration.
2. Permissions and State Transitions
The smart contract strictly restricts the operational permissions of each role through a state machine.
Key Operation Permissions Table

| Publish | Minter / Buyer | Depending on state | Minter can publish at any time; Buyer can publish during the confidentiality period; Automatically published if in arrears. |
3. Data Access Control (Privacy Access Control)
Reiteration: The Evidence Blind Box trades access permissions, not the Box itself like an NFT.

| Selling/Auctioning | Minter | Transaction not reached, remains confidential. |
| Paid | Buyer | Buyer gains access to verify authenticity. |
