If ecash sender and receiver is private from the mint is the redemption process of the ecash for lightning sats private?

Does the mint know who sent it sats to mint ecash with?

does the mint know who redeemed the ecash to send out via lightning?

Is Ecash more private than Monero? 🤔🥷

yes but it's custodial

The mint processes LN deposits and redemptions are LN withdrawals. So your privacy in both cases is the same as the privacy of the corresponding LN tx. Namely, deposits are private, because the sender is private. Withdrawals link to the receiving node.

Sender privacy is good on lightning. Receiver privacy is not. So withdrawing from a mint associates the receiver node pubkey with you

Wath do u mean with that? What do you know if I give you this: lnurl1dp68gurn8ghj7ampd3kx2ar0veekzar0wd5xjtnrdakj7tnhv4kxctttdehhwm30d3h82unvwqhhx6tcdp6kycmpwqenwwafz69

That is a WoS account. It means it is LOCKED to your mobile IMEI because WoS app cannot be installed without Google services. It means you are kind of tracked, or at least you use a disposable device. NEVER use apps that require google services.

try it yourself in https://lightningdecoder.com/

You will see there the destination of your node. But that doesn't mean we can find you, your location or who you are. It could be very easily a private node.

Why the people say that an invoice can expose the utxo that founded the channel @DarthCoin?

0 sats \ 3 replies \ @DarthCoin 28 Oct

If you open a public channel and also is not a simple taproot channel, then yes, anybody can see it in a LN nodes / mempool explorer.

Options to avoid that?

use STC (simple taproot channels)
buy channels from LSP (it can be full outbound or inbound, or mixed)
open channels with LSPs that offer on-the-fly channels (you open them by paying through LN)
use decoy LN nodes (private and public)
use decoy custodial LN accounts, also can be used to move in/out extra liquidity and fund new channels

I explained all these scenarios in many of my guides.

If I oppen a private channel with the blixt node... Then nobody knows that I have a private channel and my privacy is good for every scenario? I read your guides but I did not find this scenario.

so the mint knows which token was associated with which pubkey sats withdrawal but does not know which node sent in the sats

Why did you say the receiver privacy is not good?

22 sats \ 5 replies \ @ek 27 Oct

@DarthCoin explained in #742276.

Another privacy issue with LN in general is that HTLCs use the same payment hash for every hop so surveillance nodes could track payments which happen to route through them. PTLCs fix that.

hmmm that's why SN wants to be the "interceptor" for all so called p2p zaps in SN? To find out each stacker node?

hehehe that's why I like to run decoy nodes and wallets. Nice try SN, 😂😂😂😂

Receiver privacy is not.

Now with blinded paths, yes.

what am I doing? commenting your posts? Is that not allowed here? I paid for it, remember? Or now all comments are considered trolling ? Ok let's rename SN into "pay to troll" then.

i ask these questions when thinking about an ecash wallet where you have a username.

what activity do they know about you when using ecash and moving from lightning to ecash on that wallets platform?
