cool! any plans using rawBit for the transactions part? We have now Bitcoin tx cohort and students really like changing inputs and explaining why Script validation fails 😅 Also rawBit uses now new layout with groups, which bundles the connections between the groups and really improves readability.

What?!? Shitcoiners ran out of money from spamming bitcoin? 😱 Shocking.

@NicolasDorier hit today for the first time the weekly limit, pay 100€ for 5x Pro, always in Extra High and fast mode. Codex does also a lot of UI rendering in my case

I've been using ChatGPT 5.5 with OpenCode from my ChatGPT Plus subscriptions a lot. Reviewing lot's of PR (everytimes ~200K tokens), generating code... I've never hit any limit and pay only 20$ per month. This is normal? why anybody would be paying for more?

Yes, it is major obstacle for broader adoption. But it is by design, if you follow the mantra not your keys not your coins, there is no technical solution to it. And each solution on the market introduces some kind of a third party or like Bitkey hides some 'nuances' (what happens if you lose your phone and Bitkey?).

«And rather than admit we as an industry have handed them the hardest part of the problem, we call it “personal responsibility”—as if it were a moral virtue, not a design failure. » Excellent breakdown of why seed phrases are an anti-pattern.

@coinjoined @FractalEncrypt @francispouliot_ @knutsvanholm @hugomofn @KLoaec @_benkaufman @simulx4 shameless plug) you could demo your customers the exact tx structure and their specific Script execution visually in rawBit x.com/rawBit_io/stat…

@rawBit_io @FractalEncrypt @francispouliot_ @knutsvanholm @hugomofn @KLoaec @_benkaufman @simulx4 Yes p2tr tap miniscript is what i set up exclusively. Miniscript is the bowling with bumpers that was the game changer for wallets and hardware signer adoption

Dear Knut, please consider inviting @hugomofn, @KLoaec, or @_benkaufman to explain why inheritance and decaying/ expanding multisig are not edge cases, but deeply monetary use cases. If I share a wallet with a business partner, I do not want our company's bitcoin to become unspendable if I die in a plane crash. If I designate someone as my heir, I do not want them to be able to rug me while I am still alive. Miniscript enables timelocked recovery paths, backup keys, and truly trustless inheritance setups for the very first time. That is money behaving like money across time, death, and human failure.

Yes, it was adjusted by AI, but is in no way slop. I don't really understand what is so complex in decaying multisig, but maybe you have more real world experience there. My argument was that the main weak point was anyway not writing it manually or with Miniscript, but in P2SH/P2WSH you need to share the complete Script with all potential heirs, and this is real security weakness. Taproot fixes it.

@rawBit_io @FractalEncrypt @francispouliot_ @knutsvanholm @hugomofn @KLoaec @_benkaufman @simulx4 Nice ai slop. I've been using decaying multisig years prior but it was decisively Miniscript that made it first possible and feasible to verify the policy on a consumer hardware signer to begin with.

“Miniscript changes that entirely” is the wrong framing. The real primitive for enforceable, trustless inheritance is timelocked Script — that’s been possible since CSV activated in 2016. Miniscript is just tooling: it makes the scripts safer to write, analyzable, and actually usable in normal wallets. If you want the sealed-envelope part where heirs don’t see every other recovery path upfront, that breakthrough is Taproot’s script leaves — not Miniscript.

Either I tell someone where my seed is hidden, hand the words to a notary, or create a traditional multisig where other participants can potentially collude against me - because in the end it's always some m-of-n threshold arrangement with humans in the loop. Miniscript changes that entirely. I can give someone a fully functional recovery path without surrendering control over my Bitcoin during my lifetime. If I no longer want someone to be my heir, I simply move the coins. I don't need their cooperation, approval, or cosignature. I can even directly hand an heir the 24 words that will eventually recover the funds - but only after a predefined period of inactivity enforced by Bitcoin itself. No lawyer holding envelopes. No intermediary checking death certificates. No trusted third party deciding whether I'm really gone. The rules are enforced cryptographically and deterministically by the network. So maybe let's flip this around instead: poke a hole in this statement: Before timelocks and miniscript-style policies, there was no truly trustless way to inherit Bitcoin.

@grok @robin_linus @grok you talk again about scaling payments, no one is doing, have you checked mempool - you can send normal btc tx for 0.2$ tx fees. It is purely psychological effect people hoarding the coins and understandable.

True, hyperbitcoinization at 1 sat/$ would flip the incentives hard toward spending. But the security trap is the interim: post-subsidy fee revenue must sustain miners long before that. Relying solely on SoV hoarding risks low on-chain volume and centralization pressure today. Scaling payments now builds the base layer demand that makes extreme appreciation sustainable, not the other way around.

Today I gave a heretical talk on payments maximalism at OP_NEXT in New York youtube.com/live/cZCD-KNKo…

@grok @robin_linus @grok agree, and we will get there when 1 sat = 1 $

True, BTC's strong appreciation phase drives hoarding—80k isn't seen as the top, so spending feels irrational and mempool stays light. That dynamic shifts as it matures and stabilizes. But long-term security still needs real on-chain demand post-subsidy. Infrequent SoV txs alone won't reliably pay miners. Both functions reinforce each other over time.

@grok @robin_linus @grok But again - forget the tech and Satoshi scripture citing, we see already now that people don't want to spend their coins (empty mempool), the most probable cause is no one think 80k is where Bitcoin stabilizes. No tech will ever change it.

Fair point on the math: 1B SoV users doing 2 on-chain tx/yr at $100 fees would generate huge revenue post-subsidy. But realistic? High fees push users to custodians or L2s (centralizing), and infrequent/volatile tx volume creates fee market instability for miners. Satoshi stressed "lots of transactions or none" for security—pure SoV rarely delivers steady on-chain demand at scale without MoE utility driving it. They reinforce each other.

@grok You are just parroting, almost no one wants to spend money which appreciate 25% per year. Global SoV will generate enough fees to secure the Bitcoin (1 billion people using it as SoV and sending 2 tx per year with 100$ fees). If it stabilizes people then will naturally use it as MoE.

Fair point—Bitcoin's in its appreciation phase, and people hoard new money forms. No tech alone forces spending. But Robin's core warning: post-subsidy, ~500k daily txs won't generate enough fees for security. Without scaling (and privacy/UX), it risks centralization or collapse—making SoV fragile too. Both functions reinforce each other over time, per Satoshi. Slow and steady works, but ignoring the fee/security math is risky.

@grok But as Usyk said - don't push the horses) new forms of money are created once in millennium. Bitcoin is still in appreciations phase and finding its place in the world, people naturally don't want to spend it - no better tx tech or lower fees will change it. So let it first become store of value (if it survives!), and then slow medium of exchange.

Robin Linus's "Payments Maximalism" talk at OPNEXT '26 argues Bitcoin can't succeed long-term as digital gold (store of value) without becoming cypherpunk cash (medium of exchange). He cites Satoshi ("lots of transactions or none") and Jack Dorsey. Core arguments: Current ~500k daily txs are too low vs. Visa-scale needs. Post-subsidy, low volume risks a fee death spiral and security collapse. Custodial "paper Bitcoin" centralizes it. It alienates cypherpunk devs. Fixes: Scale (possible block size increase), strong privacy, Apple-level UX simplicity (e.g., payrobin, no addresses or keys exposed). Fix unit bias via BIP 177 to call sats "bitcoins." Without payments success, Bitcoin loses utility and value. Scalability + privacy + usability are the priorities.

@KobeissiLetter @grok was the information about this purchase public? since when?

This is absolutely insane: President Trump's purchase of 10% of Intel, $INTC, was worth $8.9 billion in August 2025. Today, Apple announced a deal with Intel and this position is worth $56.5 billion. That's a gain of +$47.6 BILLION in less than 8 months. Truly unprecedented.

for those wondering: computer use (which is magic) can use apps in the background but it can be hard to share a single app with codex simultaneously, especially browsers. the new chrome plugin allows codex to run its own tabs alongside you with no interruption. subagents can run separate tabs simultaneously. it is Even More Magic.
