Return the UUID that identifies the contract's proxiable implementation storage slot.✨ AI

开发者： Implementation of the ERC1822 {proxiableUUID} function. This returns the storage slot used by the implementation. It is used to validate the implementation's compatibility when performing an upgrade. IMPORTANT: A proxy pointing at a proxiable contract should not be considered proxiable itself, because this risks bricking a proxy that upgrades to it, by delegating to itself until out of gas. Thus it is critical that this function revert if invoked through a proxy. This is guaranteed by the `notDelegated` modifier.

_proof bytes The merkle inclusion proof.
renounceOwnership() nonpayable

Renounce contract ownership to remove the owner and disable owner-only functions.✨ AI
