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.

@npub1rxysxnjkh… Nathan did an excellent job with this interview. Simply cannot have enough reminders of the corruption and evil of the Covid regime

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.

One of the best episodes I’ve listened to in a while. Great bear market content. This makes me want a family more than I already do. @npub10qrssqjsy…

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.

This is sweet, thanks for covering this. Been getting excited listening to @npub1v25jqj332… talk about Stratum v2 for a while now. Nice to see it in action.

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.

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

The outernet stuff you're looking for the name of is Reticulum I suspect. Works over lora, Bluetooth, wifi, TCP/IP, ham radio (illegally -- its encrypted), wires...pretty much whatever you want. FIPS is another cool one you should all look at. Turns your npub into an IPv6 address. Talk to @npub1dergggklk… and Max Hillebrand

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).

One of the best podcasts on the technical sides of Bitcoin I've encountered. Helps explain why IBD is taking forever on my raspi 4.

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.

I’ve missed this Saylor. I watched a 2020 interview of his last week and it reminded me of the excitement and well-roundedness of this man. Digital credit is fascinating, but I would much much rather listen to him riff on Rothbard.

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.

    This was a very helpful overview of Bitcoin technicals. We probably need to start including things like this in early Bitcoin education

    Some of the best presentation of the issue I've encountered. Education not recommendations. The multisig evangelists are dangerous, and the guy who hosts the exchange is telling us to self custody. Man of the People @npub1cn4t4cd78… .
