It’s always good to be conservative around upgrades (as long as you’re still applying bugfix releases that fix important issues like 29.1).
But please, whether you run Core or Knots, at least run 29 and if you’re running knots enable 0-fee transaction relay so you don’t block new 0FC lightning transactions.

After more than a decade, BIP 21 has finally been replaced. Existing wallets shouldn't need to change, but this is a great opportunity to check that you pass all the test cases!
Also, if you support lightning check that you support paying to QR codes and URIs of the form bitcoin:?lightning=bolt11 (many do not) and bitcoin:?lno=bolt12offer (most do).

Sadly people nearly universally end up with an information diet of “left evil we must destroy them to save our country” or “right evil we must destroy them to save our country” these days. Means political violence is trending up and people not often than not can’t see past their own shoes. Not sure what to do about it, either, it’s just sad.

It’s so annoying having to remove emdashes from text I write to avoid people thinking I just had an LLM do it.
I’m thinking my btc++ talk should be titled “Requiem for a Decentralized Bitcoin”. WDYT nostr?
One day you wake up and realize you never made the time for that extra family visit and it’s too late.
I never understood the tailscale obsession, honestly.

Me in 2011: this bitcoin thing is cool but I really want to build a nice computer, let me sell a few coins to buy parts.
Me in 2025: this lightning this is cool, I can use it to buy nice computer parts.
Some things never change, I guess.
Underrated fact: if there’s not enough demand for (truly) censorship-money, Bitcoin fails.
Not just people won’t use it and it’ll fade (which is true), but literally someone’s gotta pay the miners, and there’s no indication anything but a real demand for censorship-resistant money will do.
I still think about how one of the very first academic papers ever written about bitcoin predicted it would fail because there’s no incentives to run a node and thus no one would and then transactions wouldn’t relay.
The CLARITY Act passed with section 110 intact. Y’all know what to do….
It’s time to call your senators! saveourwallets.org has the numbers, get to it!

Sheesh, how do I sell my name and get a windfall from a bitcoin treasury company?
Mining centralization is still horrible. Most users prefer non-private custodial wallets. Next gen wallets are lying about their trust model in marketing and people are eating it up.
Things aren’t terrible but if you’re this bullish you aren’t paying attention to anything but price.

This is not an acceptable UX. Too many wallets keep doing it, stop.

I am once again begging wallets to come up with a better user experience than having to select between a list of technologies users have never heard of on the receive screen.
One. QR. Code. Nothing more. You don’t need more, I promise.
“onchain”
Bro it’s a private database operated jointly by a few large companies that has “blockchain” in the name of the consortium.
