38 sats \ 6 replies \ @DarthCoin 28 May \ parent \ on: Why can't you buy ecash from a Cashu mint? bitcoin
You remain with a nice useless gift card that you cannot redeem anywhere.
Minter remain with your sats.
That is pure rugpull definition.
ecash are gift cards, that's all.
It's true that the mint can rug or even just be dishonest like fiat banks. But unlike a fiat bank or a custodial wallet, a mint can't target a specific user.
reply
Wrong, the server has several ways it could target a user
And wtf would you use a custodian you're worried about being targeted by?
reply
Name two of those alleged ways.

If you think shitcoins somehow move the trust gradient of a custodian, it's time to get a clue

Key Tweaking/Tainted rounds
Hmm, that's a fair point. Is anybody here familiar enough with the Cashu or Fedimint protocols to say whether or not this is a concern?
Pattern Matching/Behavioral/Heuristics
How so? All the mint ever knows is that someone is redeeming one token in exchange for another or in exchange for the payment of a lightning invoice.
Destination Blacklists
In this case, someone else could run a gateway connected to the same mint.
Spending Limits and Controls
This is only possible for outgoing lightning, AFAICT. Internally, the only thing that happens is trading one token for another. This could be limited, though.
Side-Channel Attacks
Not sure what they are.
Fee Manipulation
Again, only a problem when exchanging to lightning.
I'm not saying that ecash is trustless, but it's better than custodial lightning wallets.

Is anybody here familiar enough
No, the implementations are all larps borrowing open libraries they don't understand
in exchange for the payment of a lightning invoice
Ingest of that invoice requires other metadata
someone else could run a gateway connected to the same mint
The mint is the chokepoint, daisy chaining them just makes it worse
This is only possible for outgoing lightning
No shit, what else are the shitcoins good for?
Not sure what they are.
ECash relies on ignorance to proliferate
it's better than custodial lightning wallets
No it isn't, it is custodial completely, with worse overhead, and is an attack on Lightning's network effect as a payment spec
