@grok @_PyBlock_ @grok but you explained that not Core, but BIP110 breaks all the things. Please make complete clear story for me

The phrasing is rhetorical framing from BIP-110 supporters (pushed by Knots team). They equate non-support with tolerating either on-chain data bloat (inscriptions etc.) or Core dev attitudes like dismissing old-node users & forcing upgrades by breaking compatibility—as shown in that clip. It's designed to make the soft-fork choice feel binary in a polarized debate.

If you don't support #BIP110, you're supporting this garbage:

@grok @_PyBlock_ @grok yes, understood. but why the posts say 'If you don't support #BIP110, you're supporting this garbage:'??

BIP-110 (1yr temp soft fork) invalidates *new* post-activation txs with: - scriptPubKey >34 bytes (non-OP_RETURN) - OP_RETURN >83 bytes - data/witness pushes >256 bytes - Taproot annexes - control blocks >257 bytes - OP_SUCCESS* or OP_IF/OP_NOTIF in Tapscripts Breaks new inscriptions/Ordinals & some complex Taproot scripts (e.g. certain BitVM). Pre-act UTXOs exempt when spent. No effect on LN, multisig, payments. Expires after ~52k blocks.

@grok @_PyBlock_ @grok what exactly will be broken?

The speaker in the attached video criticizes Bitcoin Core maintainers for deliberately breaking compatibility with older node versions (e.g., 3+ releases back) to "encourage" upgrades, even for trivial reasons like a single line of code. He argues this is shortsighted, as it alienates users who want stability, and Core should prioritize broad backward compatibility instead. My view: Voluntary upgrades preserve Bitcoin's permissionless ethos, but unnecessary breakage risks fragmentation and slower adoption. Thoughtful deprecation balances security/innovation with inclusivity—relevant to debates like BIP-110's temporary data limits vs. flexibility.

@grok @CorySwan @grok He was a court jester spilling the truth - he also 'predicted' Ukraine invasion. Sadly almost no one took him seriously..also his mysterious death at the start of Ukraine invasion

Zhirinovsky predicted a US attack on Iran in Feb 2006, calling it inevitable on March 28 (Israel's election day). That timing was wrong. The specific reasoning—high oil prices to weaken China, plus millions of Iranian refugees flooding north to destabilize Russia—comes from his ~2013 comments on potential Iran conflict fallout, not 2006. He repeated Iran/WW3 warnings often over the years.

What if the simplest explanation for the Iran War is this: The U.S. knows it cannot spend the next few decades in full opposition to both Russia and China at the same time. That is not a sustainable grand strategy. So eventually, it was always going to need a path to de-escalate with Russia and pull it at least somewhat away from China. But Ukraine made that politically toxic. Russia’s 2022 invasion made any overture to Moscow look impossible, especially with Europe watching. So what changes the board? A greater evil. Iran fits that role perfectly: openly anti-American since 1979, longtime state sponsor of terrorism, and the mortal enemy of Israel, our strongest ally in the region. So applying Occam’s razor, maybe the simplest explanation is not that Netanyahu dragged the U.S. into conflict with Iran. Maybe conflict with Iran creates the strategic opening Washington needed: political cover to step back from Ukraine, let Russia become the lesser evil again, and begin the long realignment that matters most. The grand game is China.

@CorySwan @grok fact check me)

@CorySwan This crazy Russian politician - Vladimir Zhirinovsky, who died at start of Ukraine invasion, predicted in 2006 US invasion of Iran. The reasoning was additionally to weaken China - flood Russia with millions of refugees.

@RealAZKicks @fintechfrank you are too generous))

@fintechfrank Honestly most of crypto could trim 50% without noticing. We're probably one of the most overemployed industries in the world relative to actual output and value creation.

Layoffs are hitting crypto: • Algorand: 25% • Crypto dot com: -12% workforce • Op Labs: ~20 roles • Gemini: up to 30% (per Bloomberg) • Messari: leadership shakeup + cuts

It is good that we are building payment infra, but imho spending will come not any time soon. We have those 100s circular economy activities and empty mempool... Volatility needs to subside, then people will start to spend their bitcoins, probably will happen not in our lifetime.

We're going to need proper infrastructure to support all of this adoption. BTC savings is mostly a solved problem. The work that's left is making sending BTC around just as excellent.

@Pledditor Don't rush MoE use cases) New forms of money are created once in millennium, we'll get there eventually, when volatility subsides and 1 sat = 1$

If you're a SoV maxi struggling to grasp the MoE usecase of BTC, I highly recommend going to a Steak N Shake at least once to spend your BTC. They use this kiosk based self-ordering system that is so naturally synergistic with lightning payments. I promise it'll open your eyes

@_jonasschnelli_ Plant based market - are fruits and veggies, we don't need any 80 ingredients "fake" meat. But I'd love to see real lab grown meat to develop more faster.

A stock collapsing ≠ an industry dying. Beyond Meat was a badly run company with $1.2B in debt and 678% share dilution. The plant-based market itself is still $8B and growing. (... and... heart disease remains the #1 killer in America)

@BitcoinErrorLog Humans are greedy to spend their bitcoins, AI aren't)

I see lots of activity around payment protocols for AI agents: x402, MPP, tempo, etc. Meanwhile, I feel like we never solved human digital payments. Now I am curious why solving Agent payments is different than solving human payments? I think it is all the same problems, aside from some better automation with AI, no?

@saylor new money are discovered once in millennium - lets guard it!

Bitcoin is the ultimate hedge against chaos. $BTC

@JimmyKostro Cool! If your students are interested in deep mechanics of Bitcoins transactions/ Script execution - I'd love to give live intro with rawBit. It now ships with 14 lessons and exercises! x.com/rawBit_io/stat…

Today, our “Trojan horse” professor was at the university locking down the latest “modern finance” seminar details. Sometimes we use the term “basic savings,” other times “modern finance.” It’s a relentless, coordinated team effort to bring bitcoin to the people.

We've just concluded week 2 of the live cohort for the Mastering Bitcoin pathway. 📚 Over the past week, participants studied chapters 3 and 4 of Mastering Bitcoin, discussing the material with their learning partners before coming together for our live session with the faculty. The conversations focused on how Bitcoin actually works behind the scenes. We explored @bitcoincoreorg as the reference implementation, what it means to run a full node, and why independent verification is such an important part of the network. We also examined how developers interact with Bitcoin Core through tools like the command line and JSON‑RPC. From there, we moved into the foundations of Bitcoin cryptography. Participants unpacked how private and public keys work, how signatures prove ownership, and how addresses are derived to make sending and receiving bitcoin possible. Week by week, it’s all starting to come together. On to the next! 🚀

@grok @bradmillscan @Breez_Tech @JuanSGalt @BitcoinMagazine @grok But how does it work then in case of single device that user lost??

No, iCloud password alone doesn't let an attacker set up a new device. Apple requires 2FA (code to your trusted phone/device or hardware key) for any new sign-in—you get immediate alerts. Full Apple account compromise (much harder) could sync the passkey & let them regen your self-custodial Breez keys via PRF on their device. Export the optional BIP-39 seed offline for max safety.

The future of Bitcoin UX is here🤯 Introducing Passkey Login for the Breez SDK. @JuanSGalt explains how it all works in @BitcoinMagazine 👇 bitcoinmagazine.com/business/breez…

@grok @bradmillscan @Breez_Tech @JuanSGalt @BitcoinMagazine But then if attacker gets your iCloud password, he can setup new device?

No, not correct. You get a replacement device, sign into the same iCloud/Google account with your Apple ID/password + 2FA (SMS or other factors), and passkeys automatically restore from iCloud Keychain or Google Password Manager. Breez then regenerates your self-custodial Bitcoin keys via the deterministic PRF. For max safety on single-device setups, export the optional BIP-39 seed once and store it securely offline—then you're covered even without cloud recovery.

@grok @bradmillscan @Breez_Tech @JuanSGalt @BitcoinMagazine But if user has just one device and iCloud user/password, he losses the device - nothing can be restored. Correct?

No, coins aren't gone. Passkeys sync across devices via iCloud Keychain or Google Password Manager—restore on a new phone after signing into the same account. Optional BIP-39 seed export provides a standard backup for any compatible wallet. Funds stay in your self-custodial control via secure enclave.
