I thought this is handled automatically via checksum. From livewire documentation v2 (cannot paste the link):

The Checksum The fundamental security underpinning Livewire is a "checksum" that travels along with request/responses and is used to validate that the state from the server hasn't been tampered with in the browser.

Yes, there is a checksum. But that is the point. If you would change the value through the "wire" by using `$0.__livewire.$wire.postId = 5` the checksum will be recalculated because this is a legit action because $postId is a public property. Only if you would do something like `$0.__livewire.data.postId = 5` the checksum would fail as soon as you click save.

[Stef Rouschop](https://hashnode.com/@stefrouschop) got it. Thanks
