Last Notes npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Wow! Congratulations, both of you! ❤️ npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell That's great! I hope some of them work out. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell The problem with this is that well-run, boring, positive cash flow companies are really hard to find. All the obvious ones were snarfed up by previous variants of this play. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell https://media.someecards.com/someecards/usercards/MjAxMi03YWRiNGEzM2U2NWExNjkz.png npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Wild huh? Let's be friends. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Apparently the idea that we should be our best online, not our worst, is radically outside the mainstream? npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell As a Free Software developer, I've followed expansion of IP law quite closely. "Home taping is killing music", et. al. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Copyright was important and unassailable until there was Real Hot Money in ignoring it. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell This was fun! Good chat about finer grained control and incentives to mirror.... npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Not kernel, but he was Debian Project Leader at one time! npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Sometimes I forget there are old pictures of me on the internet... npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell More like "Bitcoin ALREADY HAS cured cancer, you just don't know about it yet!!!!" npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell At #OsloFF several people asked when Shit Bitcoiners Say would be back, so let me put it on the record: it's hibernating during the bear market. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Hey @nprofile…6z2t should I be pitching @nprofile…g954 to OpenSats? npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell I'm back wearing a Pebble watch! I loved the original, and wanted to support the reboot. Let's see how we go after a month... npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell This is my new Century Metadata account. I'll try to remember to post CM stuff there, not here! npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell This is really touching! npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Ah, so if I understand the meme correctly: price down means girlfriends are a scarce resource? npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell I don't understand why @nprofile…jp2l, @nprofile…6z2t and @nprofile…64cf hate each other, and at this point I'm afraid to ask... npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Official Bitcoin Twitter Self-Worth Chart npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Starting the long walk to Vienna! npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell I think it's the logical, conservative approach. I wouldn't be upset with a wholesale replacement, but I would be dissatisfied if we didn't have a fair comparison. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell That's telling it strait! npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Several people have asked about the future of CLN without me at the helm. It's a worthy question, but not one I'm concerned about. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell The only on-chain impact I'm considering is OpenTimestamps, TBH. Building a long-term venture on the assumption that blockspace will be cheap seems unwise... npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell So I'm leaving Blockstream at the end of the month, to try to start up Century Metadata. A non -profit to store and serve a small amount of encrypted data for 100 years, for a small one -time payment. Lots of fun problems in doing this, only half of then technical. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell The main benefit of LLMs is that you don't need to apologize or justify when you clean up their mediocre code. It's a bit like having an insomniac coding intern who really likes to type. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell BOLT 12 can be in different currencies for this reason. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell But now I don't even have to care! npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell https://npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s.blossom.band/692a425b55bcf45fefae7ef471794f02ed3f78ada6fe961e3cb283d9e54e7f1a.jpg npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell I've been thinking about taking profits from a Sztorc Fork. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Guess in getting up for 5:30am then. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Don't support things you don't want to see more of. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Celebration time! npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell So, we're debating paying kids pocket money in sats. Since we're talking a few dollars a week, I'm thinking ecash, using https://cashu.centurymetadata.org/ npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell https://youtu.be/iDzV_jESwGA npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell #CLN We're finally deprecating pay (in favor of xpay) in the next release: Greenlight has conclusively demonstrated that it's more effective across the board. That begins the 12 month window to removal. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell It's a threat. It's just not one yet. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell I expect Bitcoin to get a quantum scare every ten to twenty years, FWIW. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell I wish! No, it rolls back the database, deletes the gossip store if the format has changed, and checks of you've used any new features which would prevent downgrade. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell That's why we have a downgrade tool now, too. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Seems like I should try to wrangle timezones enough to join your podcast sometime! npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell We pushed it a bit on this one: There are some clients who may have trouble staying connected to you: LNDK nodes and some people who are running an older git version of LND. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Many people! I would certainly put sats towards such an effort. The winning tx could collect them all at once. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell The idea of an activation challenge is interesting. But my preferred form would be an on-chain reward. A tx which uses its first input's txid to generate the puzzle NUMS, so you can't just copy it. Not sure how to generate such a challenge, maybe GSR, OP_TX plus cleverness... npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Weekly summary: I heard Iran is going to use Quantum Black is going to crash Bitcoin! npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell There's a lot of repetitive work which needs to be done, and I'm happy to outsource that. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Claude is really happy to write more code. This can be a super-power! But it can also mean repetition, nasty workarounds, and unreviewable code :( npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell To be clear, you're thinking of deriving a second (hardened) key, for which a signature is checked in tapscript, assuming that the keypath spends will eventually get disabled? To do that we need a BIP32 path standard, and get this advice into BIP-0341 instead of the current advice on unspendable script path selection, then get wallets to implement it. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Yes. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell I've been through tech hype cycles before. They always have a grain of truth in them (otherwise they're trivially refuted) but they don't always work out. I have been through three VR waves, for example. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Obviously npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Americans trying to get back to the moon and missed. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell This one doesn't keep getting disconnected from LND and Eclair, because we disabled the padding feature which made all messages the same length on the wire which was to be a release feature 😔 npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Hmm. There are several things which could be done. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Wow, that's some lunch with the mayor! npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell "Also Bitcoin Core, but in blue" npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell No, it's all agentic payments! npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell I'm hearing them, not listening to them :) npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell I keep hearing about all the billions left on the sidelines, which will come rushing into Bitcoin when some legislative or regulatory event occurs. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Hmm, stuck in "processing". npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Actually, I'm not sure how. cashu.me doesn't seem to give me an option. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Let me try... npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Done. A bit rough, but functional. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Now I serve a web page at that URL. Probably presents too much info. @nprofile…xnfk might have suggestions for what I should put here? npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Yes, its pure API, no website. I should probably put some info there... npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Fired up a cashu mint today: should exercise my CLN node a bit more! npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell I made enchiladas, where N = 8. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Token bucket filter for the win: most occasional posters are not *regular*. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Finally read BIP-54 (mirror at https://bips.dev/54/) and it is straightforward,minimal and thorough. At this point I can endorse it as a good idea and worth doing. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell I am loving listening to the Pieter Wuille interview. It's clear from motivation to technical explanation, and Stephan shepherds the discussion masterfully! npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Here are two of my favorites: npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell https://json5.org/ npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Each Bitcoin you send has a "script" which says how it can be spent: usually just a signature for the owner's key. There's lots of other stuff yo can do though. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell https://github.com/bitcoin/bips/pull/2118 npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Randomness ("luck") is such a factor in life, and hard to disentangle. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Kick the can down the road? I cannot see the appeal from any direction... npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell You are minmaxing again. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell https://rusty-lightning.medium.com/the-three-economic-eras-of-bitcoin-d43bf0cf058a npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell You don't understand. There are no rulers. You cannot prevent people doing stupid things. This is fundamental, and hardest to emotionally grasp. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell To check the signature, you hash the transaction. So the only cost that OP_RETURN is doing is the cost to download and hash it. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell You only have to download and hash: you don't have to check extra signatures (our most expensive operation) or put them in the UTXO set (our most constrained memory resource). npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell But not relaying them disadvantages small and anonymous miners, driving centralization and thus putting my own UTXOs in danger. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell You will not be at peace until you understand the truth: every non-coinbase bitcoin transaction which does not eventually send funds to me is spam. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell So, OP_RETURN is fine, as is annex data which don't increase validation burden? And cutting off OP_RETURN and driving those uses to fake pubkeys, which does increase future validation costs, is a threat? npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell It adds an entire transaction! Every time it does that, it uses up farmore space than an 80-byte OP_RETURN. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell And does this mean you're okay with transactions that transfer NFTs? Because that's a financial transaction? npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell OTS transactions only exist to put non-financial data in the Bitcoin blockchain. Is that ok? npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell OpenTimestamps transactions aren't financial data, nor memes. So are they spam? npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Great, enjoy. Wasn't talking or thinking about BIP110, but you do you. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Indeed. Lightning commitment transactions stash the commitment number in the nSequence and nLocktime. Is that spam? npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell I thought someone would build a great UI on top of iptables. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell But but but they didn't "read the room"!!!!! npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell https://www.theregister.com/2026/02/16/semantic_ablation_ai_writing/ npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell None of those celebrating her departure are Bitcoiners. Because clearly they neither understand or like Bitcoin. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Reading comments on Gloria's departure from people who have never contributed anything is stepping in an enraging sticky fecal mess. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Suggesting such things means you're clearly not a Real Bitcoiner! npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell Reading X, I have learned that the biggest threat to bitcoin is AI Epstein Quantum attacks. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell My brain keeps conflating "Ghislaine" with "Gharlane of Eddore", the bad guy from the 50s sci-fi pulp Lensman series. npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s Rusty Russell I have been having way too much fun reading moltbook.com
