I'm torn. I am both of them at the same time.

Fumb ducks everywhere.

Don't 👏 be 👏 dumb👏.

Know that you can look at the predicted fees beforehand and that you can also make on-chain payments using Phoenix too right? nostr:nprofile1qqs9qp2dql3vmuetzq6hw77eeaeej2j2ughers22wch0m2jm7c05w4g7fd4xj

I'm torn... this looks very AI yet it has been cryptographically signed as authentic... fuck.

BitCoin is dead guy, Satoshi called it.

We should add integrity attributes. We don't want to get rugged in the future while we aren't looking.

I wouldn't say backed by, but rather a promise for. But yeah.

Also you can't move across mints without lightning, lightning is what connects them and what connects your ecash to payments.

I.e. when you pay a lightning invoice, you actually tell the mjnt to pay the invoice and provide ecash to prove you owned the appropriate amount to pay the invoice and to ensure you can't ever use that ecash ever again.

Cashu is custodial. It's been said, it keeps being said. If you want trustless, cashu ain't it. If you move cashu from one mint to your own, you're better off paying a lightning invoice to yourself instead.

Stop striving for trustless and instead explore how much trust you are willing to embrace and for what value. Can you batch payments with a reasonable amount of trust?

Also, don't recommend cashu as a trustless tool to others.

GM. To you!

Don't think this is a real quote.

I mean... it makes sense. The people who are experts at taking on debt are ranking your ability to take on debt. I guess 🤷‍♂️

Cashu is custodial. The mint has the keys, the mint owns the bitcoin. It is a bank and has custodial risk.

However, cashu offers seamless perfect privacy. The mint knows nothing about who has their tokens, how many, or what anyone's balances are.

That privacy means that they can only ever rug everyone or no one. They can't selectively rug you alone.

Also in terms of receiver privacy, when you receive payments over lightning, you usually expose a node id. With cashu, that node id is used by you and potentially hundreds or thousands of other people. You're hidden behind an unknown and potentially massive anonymity set.

Win some, lose some 🤷‍♂️

Ooh, I like the visual rendering of that cashu token...

I can imagine if wallets presented it looking like that... even though they aren't there to be read or physically copied by humans... the cashu token would still look/feel more real to people.

I'm kinda imagining it on printed ecash notes.

I think this happened because I installed an update while it was finding and trying to claim zaps.

I think they are gone forever?

Not everyone will learn by reading source. Most of us with a decent understanding of this stuff have been exploring and pontificating for years.

Everyone must start from somewhere, but I mostly agree.

No one has finished evaluating or understanding bitcoin and its many facets, and it is okay to speak your understandings if you also accept that you can be wrong and are open to feedback.

I don't know how community feedback works, but if, as this suggests, people are replying with their misinformed opinions in a way that CANNOT be challenged, then this is a terrible feature where one possible inaccuracy can be corrected with another inaccuracy without recourse.

That ain't code, that's psychopath!

Somebody must get 10 sats, and somebody else must get 11 sats.

Let's be clear:

1. The introduction of quantum resistant Bitcoin addresses does not require you to change your seeds.

2. If quantum computing does break some cryptography, then people may need to start creating and moving funds to new wallets.

The key word _may_ is because there are multiple layers of protection here.

Quantum computing is not magic, it has limitations and we don't yet know any theoretical way to break the different protections in Bitcoin.

Between a private key and a taproot address there is:

- RIPEMD-160 (A hashing function)

- SHA256 (Another hashing function)

- Secp256k1 (an Elliptic Curve Cryptography ECC function)

Possibly other functions too that are non reversible.

There is hashing: I've heard that sufficiently powerful quantum computers could potentially find collisions and "break" the hashing used in Bitcoin.

However, this does not mean you can REVERSE a hash. You might find the word "hello£+*" is a collision for your bitcoin address, that doesn't mean that "hello£+*" is your public key... Being able to find hash collisions doesn't mean being able to find collisions that are also valid public keys. Not only that, but if quantum broke one of the hashes (e.g. SHA256) doesn't mean it will break the other.

Now if these were broken completely, then an attacker could find your addresses public key, but not the private key behind that. You also always reveal the public key each time you spend anyway. This is one of the reasons why you should never reuse addresses.

Then we have the ECC algorithm. Again, I don't believe there is a theoretical way to break our specific algorithm, but there are theoretical ways to break many ECC algorithms so I think most people are talking about this when they say Bitcoin is not quantum resistant.

It is also mixed in between the hashes anyway so breaking just this doesn't allow a quantum computer to go from your public key to your master private key.

MAYBE it could reveal a specific address's private key, but not your other addresses.

Bitcoin is pretty quantum resistant and it's used of hashing is one of the main reasons. But if we had to overhaul everything because all of the functions were found to be completely broken and then we built a powerful enough quantum computer, then yes: you'd need to create a new wallet and move all your funds.
