Add an option to block the content update of a transaction

[redDwarf03]

Is your feature request related to a problem?

For example in case of NFT, if we host an image in the content of a transaction, we shouldn't change the image.
It's necessary to block this information

Describe the solution you'd like

add a smart contract in code field

condition inherit: [
uco_transfers: true,
token_transfers: true,
authorized_keys: true,
secrets: true
]

Additional context

No response

One way to do this without involving contracts can be to encode in base64 the image in the NFT.
But for this option, while for single file deployment this might work, for multi files this could be complex; particularly to determine which files to lock in a website deployment context

[redDwarf03]

this issue concerns only the host of one file (eq 1 NFT). Not a folder or a website

It could be a nice feature indeed

What about this outcome?

Is it worth leaving it open?
