0 sats \ 84 replies \ @Scoresby OP 28 May 2024 \ parent \ on: Why can't you buy ecash from a Cashu mint? bitcoin
Is it "inherently custodial"? If the mint turns off its servers, everyone's ecash from the mint is gone. I don't think this is the standard definition of custody.
The mint can indeed stop me from trading my ecash or even from the ecash existing at all, but only on the condition that the mint commits suicide.
This is a different trade off than typical custodians where the custodian can interfere with a specific user.
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.
reply
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.
You're effectively saying your coinbase account is non-custodial because there's a cookie in your browser
The mint can use any number of heuristics to programmatically block a specific redemption
Put down the kool-aid, it's a scam dude
reply
Did you read the Wallet of Satoshi example? There is a difference in trade offs between database entry and ecash from a mint.

I'll accept this could be the case, but heuristics don't sound like a sure thing.
Do you at least acknowledge that an ecash mint can only rug if they rug all users at once, whereas something like coinbase of WoS can rug one specific user if they like?
reply
Yes and it demonstrates you have no idea how any of this works.
The trust level is the same, the privacy benefits are illusory.

No, that's retarded you would even think that. The gateway can execute any logic it wants.
reply
Rugging has nothing to do with the gateway. Mints can rug. Gateways just choose to act as a gateway or don't. They have no effect on whether I continue to hold the ecash.
You say you are stating facts:
The trust level is the same, the privacy benefits are illusory.
This is your opinion. Demonstrate it with an example or something. Or discuss it further. Just saying it isn't fact.
reply
From your OP
I trust WoS to update a spreadsheet they have that credits those sats to my account
do some fancy math to issue an ecash token
Before I make assumptions about what you are implying here, are you suggesting that Sats to ECash is less trusted than Sats to SQL Record?
reply
No, I'm suggesting it results in different levels of visibility into the transactions that happen within the mint versus those that happen within the SQL database.
