I'm wondering if there's a Nostr client that has the functionality to show a specific user's notes in chronological order. My hunch is that this is more about the relay's ability to handle such requests efficiently than the client's, so it might not exist, but I figured I'd ask just in case.

Every time I heard about #cashu, I was fascinated by how blind signatures work. To be precise, my wonder wasn't about the ability to sign something without knowing its content. Considering the commutative property of elliptic curve cryptography, it's certainly possible to create a valid signature without knowing the content. My real question was: wouldn't this cause issues during redemption if the content wasn't known? If I deposit 10,000 satoshis and receive a 10,000 satoshi IOU token, how would the mint know how much to pay me later if it didn't know the content? I struggled to find detailed explanations of this specific point in blog posts (ironically, after I understood it, such articles started appearing). It was only after diving into the NUTS standard and the code implementations based on it that I had my "aha!" moment. It turns out there aren't tokens of arbitrary face value at all. Instead, there are separate key pairs for denominations that are powers of two, and your balance is made up of combinations of these. Naturally, signing without knowing the content doesn't cause any problems during redemption, because the content and the amount were never directly related in the first place. If #ecash wallets displayed balances in a similar way to how on-chain wallets with coin control show each individual coin, I would have grasped this concept immediately.

비트코인은 오스트리아 학파에서부터 이어지는 아나코 캐피탈리즘의 구현체라고 저는 보고 있습니다. 그쪽 이론을 접하다 보면 경제학 부터 시작해서 사상과 윤리 문제로 나아가는게 근간에 있는 것은 논리적 일관성이었습니다. 최소한 제 이해의 수준에서는 말이죠. 저에게 어필한 부분도 그것이었고 말입니다. 왜? 왜? 왜? 를 반복했을 때 본인이 했던 말을 번복하지 않는 일관된 논리를 보여주는 것은 아나코 캐피탈리즘 뿐이었습니다. 그런데 안캡에서도 왜 논리적으로 일관되어야 하지 라는 의문엔 명쾌한 해답이 없다고 느꼈고 그 부분을 채워주는 것이 결국 종교가 될 수 밖에 없는 것이 아닌가라는 생각을 하게 됐죠. 그리고 그 역할을 수행할 수 있는 것은 제가 봤을 때, 소거법으로 아주 일부의 기독교 종파 밖에는 없다고 느꼈고요. 저는 사실 십계명만 잘 지켜도 어지간한 자유주의자나 비트코이너보다 훨씬 더 자유의 가치를 잘 이해하고 있다고 봅니다. 십계명을 직접적으로 지키는 것 뿐만이 아니라 간접적으로도 지킬 수 있는지, 즉 저것을 지키지 않는 자에 대해서 반대할 수 있는지를 일관되게 행동할 수 있다면 저는 양립가능하다고 봅니다

I just reinstalled 0xchat after deleting it, and while I was messing with the settings, I remembered I had some ecash in my 0xchat wallet. I just realized another revenue stream for the mint, beyond Lightning Network routing fees or withdrawal fees. Congratulations to the mint! Considering that ecash is mostly used in very small denominations, people likely won't bother backing it up carefully. If you add up all these unclaimed funds, it'll amount to a significant sum.
