| Are there situations in which I would not want to use the Provable versions? If the conditional logic is not part of your provable code, you do not need to use Provable conditional statements. |

@garwalsh we don't need to capitalize Provable (unless it's a proper noun?)

by Require a signature as an input. do we mean to use the default value of signature? like https://docs.minaprotocol.com/zkapps/o1js/permissions#default-permissions
or do we want to set explicitly set the input field permission to signature? (or something else entirely?)
I was looking for a doc to link to, and found out that I need to learn more about what this means.
Permissions doc https://docs.minaprotocol.com/zkapps/o1js/permissions
signature: Fields that have their permission set tosignaturecan only be manipulated by account updates that are accompanied and authorized by a valid signature.
Or do we mean something as described in https://docs.minaprotocol.com/zkapps/o1js/interact-with-mina#signing-transactions-and-explicit-account-updates ?
Signature authorization – used to update user accounts. Signatures are verified against the account's public key.

@garwalsh for questions like this, let's link to a doc for more learning. See my (many) questions, thanks |
| ### How do I restrict a provable method so that it can be invoked only by a specific address? | ||
|
|

| There are a number of ways to accomplish this: | ||
| - Provably add a signed child account update. Then, the method can be invoked only with a signature from the predefined address. |

I was looking at open PRs and noticed we let this one get stale... do we want to discuss? @garwalsh
