Read about the 30 maidens of Geneva. Quite remarkable. However stupid you think the bureaucrats running your life are, they'll struggle to compete with late18th century France. It's actually a perfect model of why adversarial thinking matters. In the absence of an adversary, choosing the price of the annuity for the average buyer (age 50) is an efficient decision.

Why are signet blocks only mining 1M weight not 4?

Excellent summary. I think the final paragraph is the most important, but also: at least in theory, any particular round with a central coordinator and anonymous counterparty, cannot be guaranteed to not be Sybiled by the coordinator. With any form of coordination, that's possible; indeed that was a common early critique of Joinmarket, and even imposing anti-Sybil style costs doesn't remove that risk, either. The reason I always saw that risk as worse with a central coordinator was the standard CPOF arguments. Let's not forget that a central coordinator offers big advantages, too. View quoted note →

Fabian Jahr put out a concrete proposal for DahLIAS!

This is a CISA proposal with a security proof. I was hoping there'd be more comments on DahLIAS by now, but having read it myself (the paper, not this BIP, yet) I think it's solid; the only part I didn't like, I was convinced by the authors is just aesthetics. Drag yourself away from PQC panic or bip110 panic, if you dare 😄

Every now and then i learn a new Spanish idiom that genuinely makes me lol. Today it was "Es tan feo que le da un susto al miedo." 😆 (Something like: "he's so ugly he gives fear a fright") I can't think of an English idiom that has such a streak of abstract absurdism. Hat tip "Erre que ELE" on youtube.

DJB is one of his periodic tirades against NSA interference. His current campaign is to argue against the (probably genuinely really bad idea) of forcing everything to PQC instead of PQC+ECC. It's honestly hard to see good arguments why he's wrong other than ... well, the NSA actually backdooring and/or controlling things. I particularly liked this part: "I have a paper that exploits a simpler tightness gap in another lattice-based cryptosystem, FrodoKEM. For example, the paper shows that if you send 240 ciphertexts to a frodokem640 public key then one of the ciphertexts will be decrypted by a large-scale attack that's feasible today. This is beyond an academic demo, but it does disprove an official FrodoKEM security claim. That version of FrodoKEM was then officially renamed "ephemeral FrodoKEM" (which I think means we're supposed to forget this version ever existed) and was officially replaced with a revised "FrodoKEM". " 😄

Claude finally flagged me as a cybersecurity risk. Well fuck I might have to use my brain now. 😫

On the other hand, they can also use it against you...

Claude Code Is Steganographically Marking Requests

I inspected Claude Code for privacy reasons and found hidden system prompt markers based on API base URL and timezone.

This stuff is neither amazing nor egregious, imo. But it *is* sneaky. Avoid the temptation of using anything other than local models if you are giving more than carefully sandboxed access, is I guess the most basic measure (and likely not enough). View quoted note →
