Yes. And @Scoresby's original point is that at least you have a promissory note instead of just hoping that WoS keeps your database entry.
No, WoS knows your balance because you have an account with them. A mint doesn't even have a concept of an "account". All it deals with is tokens. It doesn't know who has what tokens.
at least you have a promissory note
There's 0 difference, but this asinine standard the signed SSL packet with a balance response from WoS is also prom note
A mint doesn't even have a concept of an "account"
Wrong, every creation event is subject to the attacks I already mentioned. This also ignores the fact that WoS keys can be ephemeral, you can have 1 or many, they only know what you tell them.

Regarding WoS keys, they'd also be subject to analysis attacks similar to the ones you describe.
Regarding mints, WoS keys are always linked to a balance. Mint tokens require a lot of work to associate, if it's possible at all.

linked to a balance
PARTS of a balance, not necessarily a whole balance, not unlike each new minting event
Mint sees what channel sats came into and how much, it sees when they go out and how much... same thing WoS sees... the arbitrary numbers on a token or in a record are equal

OK, so do you admit that ecash isn't worse than WoS?
reply
Inherently? No
Practically? Yes
Keep in mind that the scammers and spooks aren't pushing ECash as an authentication scheme, they're pushing it as a payment spec... this is an attack on Bitcoin and thus much worse than WoS
reply
How so? It's no worse than trading pre-loaded WoS accounts.

they're pushing it as a payment spec

Then I'm not sure I understand what you mean by "payment spec".
