In this third Coldcard Q&A, I tackle entropy, device trust, DIY signers, and why I’m leaning harder than ever on multi-sig. I walk through why understanding encryption must become a mandatory survival skill, rather than a niche hobby, if we want to resist a dystopian future. I also share where I moved my personal stack, explain how multisig actually saved me, and explore the impossible ethical nightmare of white-hat hackers trying to rescue compromised wallets. Chapters (00:00:00) - Introduction (00:00:22) - The future of Coinkite (00:02:28) - Refunds or going dark? ...

'Rear admiral' 😅 Tom Luongo calls him Big Gay Patton. Still amused Trump brought us the highest ranking gay man in American history.

The thing about Bitcoin wallets is, you can have more than one. Soapminer? You're paying Lightning. Rent? Maybe a hot wallet, or single sig. Retirement savings? Multisig offsite. Generational wealth? You're adding miniscript. You don't keep are your fiat in your pocket. Don't do it with your Bitcoin either.

A million times yes. Thank you for addressing this in the right way. You're one of the only podcasts that hasn't responded to Coinkite with yet more bad options. Very much excited that Learning Bitcoin From The Command Line is getting a new edition too -- long overdue.

Re:other nodes and making news, you're clearly not watching Eric Voskuil on Twitter. Libbitcoin 4 just did IBD in 14 minutes on a consumer connection (with assumevalid height of 950k) and 55 min for full validation. Older than Knots, and older than Core being called, well, Core. They slept for a good few years but are waking up with a vengeance.

Ben, if you see bears in the future, give them something they'd want instead of grapes. Picnic baskets.

Welcome back Walker, congrats on the bigger family Also, xpubs will only give unhardened addresses. That said, I expect a Venn diagram of people who didn't roll dice and people using hardened addresses is probably two separate circles.

People would hit me with things suggesting Slackware to a Linux beginner, but you seem keen on appropriately following documentation, and it's got some of the best documentation, and very vanilla software which makes using upstream documentation easy to use too. Some key audio thoughts too. https://web.archive.org/web/20260426090835/https://blog.sla… Doing your work you may want more than the standard pulseaudio back end.

Robinhood's 'tokenization' sounds more like an Exchange Traded Note (ETN) that is just a liability of Robinhood and traded on chain. These aren't new, but putting them on chain is. The SEC is talking more about trading actual stock ownership using the chain as a ledger. Very different despite the similar performance in ideal circumstances. If the stock goes up but robinhood goes under, you are out, while with the shares the SEC is talking about, you're good. Maybe a little market downtime, but you'd just get regular shares with SIPC coverage.

The cloak and dagger shit with Switck is heating up. People were already looking for a reason for this to be inside. Still not totally convinced but it looks sketchy as fuck. Never been more glad I had fun playing dice games with my bitcoin.

One of the best WBD's yet. Dines' coverage of the Eurodollar mechanics here and the shift that happened with LIBOR to SOFR is something far too few people are talking about (Luongo notwithstanding).

ACK to more students coming out. Did you not hear @npub1fhmmgwe6f… say there's free food?😄 But seriously pushing the conversation back into classrooms and engaging other academics helps engage more valuable resources. Student engagement disporportionaly can help move the needle. Besides, the more you're into bitcoin when you're a student, the more you're retired when you're 45-50.

I was thinking at some point you'd want to reset the top boosts, so the top and 33 days seems like a good solution. Might also consider different time frames for the size of the boost. Like over 1M doesn't expire, over 100,000 is good for like half a year, etc. Just an idea. Always enjoy the interviews and the things you come up with. #40hpw

Cutting out other forms of collateral is where stablecoins can drive up treasury demand. Currency swaps and other credit instruments are huge in repo markets, as is rehypothecation of the same underlying collateral. Stablecoins don't hold claims on treasuries, they hold treasuries. They don't hold gilts and forex swaps, they hold treasuries. There are problems that come with some of the solutions here, as there mist be as the whole game of fiat is a game of jenga. But short to moderate term they can seem to cannibalize demand for other collateral and chains of rehypothecation in order to reduce treasury yields.

Infinite divisibility would be cool but floating point math is all sorts of problematic. Infinite divisibility is trivial on L2+ though as it is.

I would think it's how someone is trying to crack your pass phrase. If they are brute forcing each character, the longer multiple words would be harder, but if they know it's bip39 words, that would definitely reduce the number of possibilities they'd have to test. So in general longer is better. #40hpw

FWIW, I definitely started faster speeds with audio books. Figured it was kinda like speed reading, also it seemed like the best way to get through a bunch of stuff, when you don't know of its worth your time or not. But I have noticed I retain more when I listen at normal speeds. #40hpw

He doesn't believe there was ever a major improvement to Bitcoin, but wants payment rails. Yea, tell me you don't understand Segwit without saying so, especially while touting Lightning's use. Not surprised here.

    Maybe white hackers who don't know the person, could just donate the sats to development. Like if the owner of this address can let us know where they want this BTC donated, at least that would keep everyone from claiming that address. And it would be better for everyone than burning it. At least if I lost everything, I'd feel better knowing that it was going to make a better world than to some selfish crooks. #40hpw

    The worst possibly blow arguably would have been nonce reuse. That'd have hit even the dice crowd.
