真相盒子（Truth Box）

链上数据结构​

struct PublicData {
  Status _status;
  uint256 _price;
  uint256 _deadline;
}

struct SecretData {
  address _minter;
  bytes _encryptedData; // Encrypted payload (private key / evidence key)
  bytes32 _nonce;       // Encrypted nonce, requires decryption
}
  • PublicData：公开的状态、定价与截止时间，用于交易撮合与到期判定。
  • SecretData：由 Sapphire TEE 加密的机密字段，含创建者地址、机密数据密文与随机数；仅经授权的 SIWE + 合约校验方可解封。
  • Truth Box 既是可转移的 NFT 载体，也是机密数据的访问控制入口。

metadata​

TruthBox 的元数据文件有两种,分别对应创建 TruthBox 的两种方式：create和createAndPublish， 以下展示了它们的主要区别。

create​

包含了对称加密后的数据。

createAndPublish​

不包含对称加密后的数据，而是直接存储了文件的 CID。

    "slicesMetadataCID_encryption": "",
    "slicesMetadataCID_iv": ""
  },
