I don’t think it would be correct to imply that this thing contains an asset. It more represents an asset.
In the same way a bank note represents an amount of currency, or a title deed represents a property. Neither of these contain the asset.
With a container metaphors, such as folder, or wallet, or safe, it is implied that many things can be stored within, and it can be added to, and have things taken out. These things aren’t true in this case.
(Although yes, it can represent more or less than one SNT. Like a bank note can represent more than one unit of currency. I pointed this out to highlight that calling it something like a coin, or a token, might be awkward)
It also would be misleading to imply it can be locked and unlocked. Because that might imply it is normally in a locked state, and therefore ok to share it, or leave it accessible. This is not the case. Yes, I need the private key to spend it, but I could still have privacy issues if it is shared, and without the public key I lose the asset.
So, these things need to be kept secure somewhere… like I dunno… in a safe!
It’s not to represent a wallet specifically no, but a more broadly useful container for any kind of data, including these financial ones.
To quote myself…
This is the concept of a Safe. And it could act like a wallet too, that would simply be about the client surfacing the financial data (like the CashNotes) and allowing me to see a filtered view of that.
But the point this is a container that is acting like you describe @happybeing, and we don’t really need other classes of container to do that job I don’t think. You can nest them, have n of m, hold them locally, or on the network, give them addresses etc… very versatile.
