Been finding @PayPerQ more and more to my liking over time. I can use models more privately with the TEE feature. I pay with LN anonymously, i can see exact costs to the cent. I wonder if more features can be added for switching between nyms more seamlessly.

abcbadq's magnum opus. (Fallen Symphony - Ludicin) Map is hard as balls. But it's absolutely epic, especially the last 3 minutes. Not joking about magnum opus, abc is the most prolific (mainstream) mapper in the game, and there's always some creative flair in every one of his maps. This one is some kind of culmination of years of his craft, across 9.5 minutes it manages to include so many different patterns, many extremely difficult, and represents the music fantastically. #beatsaber

Gmax on proposals to add tail emissions to bitcoin: "but I agree with Sipa that these inflationary notions are a non-starter philosophically and morally. Particularly because anyone can create their own cryptocurrency with whatever rules they think are superior, and if its good people are free to adopt it. In such a world trying to impose such a radical change to the premise of Bitcoin would be inexcusable, and ultimately self defeating since if bitcoin doesn’t even have durability of its monetary policy why does it exist at all?" Unlike in technical questions, where in my experience Greg ends up being right 95% of the time, I found myself disagreeing with his take on philosophical things a lot more often. Most particularly around freedom of speech questions. Yet, I'm 100% with him on the above (and he expressed it very cleanly), and I (by the same token) completely disagree with @Peter Todd

I wonder how many Americans are aware (because I don't think I've ever heard one mention it) just how uniquely obnoxious the transit system in their airports is. You might not immediately grok what I mean; you might think "foreigners aren't entitled to anything" but in which case you didn't get my point - my point is that *for a traveller who has no interest in entering the United States* the experience is uniquely obnoxious. Every other major international airport has what's called "transit". I'm going from country A to country B with a connecting flight in country C. if C != USA, I just stay in the pre-immigration area and move over to the other flight; sometimes they have baggage checks (and ticket checks ofc), but not full blown immigration, because you're not entering the country. The problem is that the USA is a *major* hub for flights, for the Western hemisphere; it's not trivial at all, to avoid it, for some routes. And couple this with the fact that US immigration is not exactly relaxed (which is fine, but is not fine when you have no intention of stepping foot in the country ...) Why? And as bad as it is for me, I could use the 'visa waiver program' (still shit - still have to go through immigration) but many countries don't have that entitlement, meaning a citizen wanting to travel *via* (again, not into, via) the US would have to do this just to get to their non-US destination. Which goes from obnoxious to .. I don't know, surreally obnoxious.

What really amused me about Borges' Library of Babel is how he goads the reader by giving them all the exact numbers required to count exactly how big the library will be if it contains every possible book, once, but then stops short of counting and starts musing about infinity :) Even more amusing is the discussion of the fabled catálogo 😄 ... which can't exist. The *contents* of the library is ~perfectly compressible ("print every book length N" does it), but the *ordering* of the library, which is the purpose of a catalog, is perfectly incompressible: the only catalogue is the library itself!

Nothing about the two transactions shown is strange. The first is 2 in 2 out, the second is 1 in, 2 out; normal payments [1]. If you examine their witness you'll see they're like 90% of other taproot transactions, just keypath, no scripts involved. But in fact, this is a bet. Two parties flipped a fair coin for the winnings (a small chunk of the input funds). Not literally; they used cryptography to get an exactly 50% chance of winning without having to trust the other. They were both running signet nodes (in fact I had one on my laptop at home and another on a VPS), and used decoy packets in BIP324 (bitcoin p2p encrypted transport) to communicate, so no one could even know the negotiation was happening (side note: this idea feels like it should be useful in many other contexts, and it's surprisingly easy to set up, with a very simple patch to your bitcoind). So we have a fair bet inside a coinjoin; you could think of it as a randomized payjoin if you like, but, the transfer of funds is not for some goods and services but, just a wager, and it's perfectly fair because of a cryptographic trick that was discussed on delving [2] though it's changed from what was written there. Payments inside coinjoins break subset sum analysis; this is just another kind of payment. Amongst other virtues of such a system is that it creates economic activity between peers without middlemen which is vital to Bitcoin's general pseudonymity. The implementation is at . The repo is currently 95% AI-written so not very readable (still not *unreadable*, but, y'know how it is) but I have a paper that I've nearly finished that is human written and human readable for those interested in the mechanics. [1] In fact those familiar with details of payjoins *will* see something specific about the 1st transaction that makes it like a payjoin. But it isn't hard to remove that, and anyway, it's only a watermark for 'this is a payjoin', not for what it *actually* is... [2]

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.

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 →
