Core Mechanism Specifications

Game Fairness Verification Flow

Key Technical Points:

• HMAC-SHA256 layered seed mechanism

• Verification formula: Result = HMAC(ServerSeed, ClientSeed + Nonce)

• Integer games (0/1): Result % 2

• Float games (0.1-9.9): (Result % 99)/10 + 0.1

2. Data Attestation Scheme

Data Type	Storage Method	Verification Method
Game Metadata	IPFS (CID recorded on-chain)	Reverse query via CID
Critical Parameters	BSC Blockchain	Direct blockchain explorer check
Fund Operations	Smart Contract Event Logs	On-chain transaction verification

Sample Attestation Structure:

{
  "game_id": "0x8a3b...f21c",
  "player": "0x5B38...C7",
  "result_type": "float",
  "result": 7.2,
  "proof": "ipfs://QmXy...9vE",
  "timestamp": 1720324555
}

3. Fund Protection Mechanism

Multi-Tier Safeguards:

1. Third-parties must deposit minimum collateral to reserve pool contract

2. Daily automatic audit of platform fund coverage ratio

3. When protection triggers:

1. function compensate(address player) external {
       uint amount = min(balance[player], poolBalance * 0.95);
       payable(player).transfer(amount);
   }
