You should talk to Keith from seed signer about entropy. He has been putting in the work including showing why dice rolls aren’t that “risky”
I’m unconvinced anyone should ever use a passphrase - should never be compared to multisig.
The single sig focused hardware marketing budgets will always try to convince you otherwise. I have no regrets in trusting level headed research from open source and DIY devs over corporate marketing.
Is Rolling Your Own Entropy The New Standard? (Coldcard Q&A P1)
By Guy Swann

Chapters
Show Notes
In this Guy's Take, I walk through listener questions and comments on the Coldcard random number generation failure and what it really means for Bitcoin self-custody. We dig into why the RNG bug went unnoticed for years, the difference between source-available and truly open source hardware, and how dice rolls and strong passphrases change your threat model. I also share how I’m thinking about safer setups going forward.

1.6k 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.

1k 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.

580 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.

500 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.

500 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).

100 A hung jury isn't an acquittal, it's a mistrial. Jurors aren't voting, they're deliberating to arrive at consensus. If they can't, it's a do over.

100 Your analogy is odd given that the twentyfirst amendment struck the 18th amendment from the constitution...
The issue with 110 is that it was ineffective and targeting an issue that barely qualifies as one. 4 MB is 4 MB.

100 The point of airgapping isn't that QR'sbor SD cards are inherently more secure than USB or Bluetooth. It's that the amount of data is far more limited and easier to audit with lower tech methods.
If you ask me floppy disks would be even better, as SD cards have firmware that could be an attack vector. But floppies are prohibitively hard to implement in 2026.

The multisig evangelists are dangerous, and the guy who hosts the exchange is telling us to self custody.

100 I'm thinking the four year cycle is not as there as some have said. Stephen Perrenod has some great writings and math to go with it on some harmonics describing oscillations around the power law trend that seem to make more sense when thinking about fundamental factors. And it follows log time, with the last peak in 2017 and the next in 2027. There are sub harmonics, hence oscillations in between. The fun thing is, it captures the 2011 run up too...

100 Someone's out to capture Bitcoin all right. It's the ones who are running thebonly implementation and mining pool that supports this dumbass fork.
They're just a lot more retarded than even Bcashers, with a single percent of blocks in any signalling period so far with only 2 to go.
Most don't know enough about Bitcoin to realize how cooked they are though. And the ones who do are too sour to do anything about it.
Have fun storming the castle.

100 I gotta say Rustin, I'm pretty disappointed in the portrayal of spam being about data space. That is hard capped at 4 MB/block. Being opposed to using that space is to be opposed to Bitcoin being used.
Spam has other issues, sure. But the size on nodes is Simply noise.

100 Just gonna point out as a non-MSTR lover that $82.50 with 11.50 in annual dividends is a 13.94% yield.
So when you say STRC hasn't done well but SATA has it's a bit weird as they're trading for the same yield...

I don't get why everyone says random generation was the most important task. It'd have been a better signer than any on the market if it didn't have an RNG at all. It was a task that if you're gonna do has to be done right though.

If anything after the entropy fuckup, they were /are lot of eyes on the coldcard code and other wallets . Coldcards force user entropy now (latest firmware) so I think they are now ok to use , even to generate the seed, hopefully they go fully open source not just src code available. So don't throw the device just yet
