external {
require(ownerOf(tokenId) == msg.sender, "Not asset owner");
require(authorizedServers[gameServer], "Unauthorized game server");
require(!assetsInGame[tokenId], "Asset already in game");
// Lock asset for game use
assetsInGame[tokenId] = true;
gameServers[tokenId] = gameServer;
emit AssetBridgedToGame(tokenId, gameServer);
}
function returnAssetFromGame(
uint256 tokenId,
bytes calldata updatedMetadata
) external {
require(gameServers[tokenId] == msg.sender, "Unauthorized server");
require(assetsInGame[tokenId], "Asset not in game");
// Update asset metadata based on game usage
_updateAssetMetadata(tokenId, updatedMetadata);
// Unlock asset
assetsInGame[tokenId] = false;
delete gameServers[tokenId];
emit AssetReturnedFromGame(tokenId, updatedMetadata);
}
}

// State synchronization system
contract GameStateSynchronizer {
struct GameStateCheckpoint {
bytes32 stateHash;
uint256 timestamp;
uint256 blockNumber;
address gameServer;
}
mapping(address => GameStateCheckpoint[]) public playerStateHistory;
mapping(bytes32 => bool) public verifiedStates;
function submitStateCheckpoint(
address player,
bytes32 stateHash,
bytes calldata stateData,
bytes calldata serverSignature
) external {
require(authorizedServers[msg.sender], "Unauthorized server");
// Verify server signature
require(verifyServerSignature(stateHash, serverSignature),
"Invalid signature");
// Store state checkpoint
playerStateHistory[player].push(GameStateCheckpoint({
stateHash: stateHash,
timestamp: block.timestamp,
blockNumber: block.number,
gameServer: msg.sender
}));
verifiedStates[stateHash] = true;
emit StateCheckpointSubmitted(player, stateHash, msg.sender);
}
function challengeGameState(
address player,
uint256 checkpointIndex,
bytes calldata evidenceData
) external {
// Allow players to challenge game state if they detect inconsistencies
GameStateCheckpoint memory checkpoint =
playerStateHistory[player][checkpointIndex];
// Initiate dispute resolution process
_initiateStateDispute(player, checkpoint, evidenceData);
}
}
