# ZK Proof

We have one last thing to investigate - the zk proof generation of the gameplay procedure.

Now click the "Game Proof" button on the top header of this page:

You will see a popup window like this:

This is the step history record window of your gameplay. After you play some steps, it will become:

Every square like "3:i64" is a step record of this gameplay. And while you end this game, such like:

Check the game proof window:

The steps increased, and right now we can create a proof for it.

Click the red button at the right-bottom corner. A wallet popup will be triggered, like:

After the signing process, it will generate a zk proof for this gameplay and submit it to the Blade game server.

Now we have finished the entire ZK game development flow, next you can make your own game according to this guide. Good luck!
