Best option* for running your own #bitcoin full node: * Used bare-bones ThinkPad w/8GB RAM * Replace ssd w/cheap 2TB nvme * Run it as some flavor of linux For $220 you have a solid enough machine WITH a screen, a keyboard, and -- super-important -- a BATTERY!

PSA: don't rely on ANY hardware wallet to be your sole long-term storage. Someone once told me their plan was to bury a hww and not touch it for 20 yrs. You CANNOT assume that hardware will keep functioning. Long term backup = mnemonic seed phrase. Period.

Sorry, but people need to stop saying that multisig is hard. It's not. Multisig has one "gotcha": you must have your wallet descriptor*. That's easy. Don't misrepresent "this one easy thing is really important" with "ack, it's so hard to do"!

1/Why #bitcoin matters now. Trump wants to look good for 2020. No surprise there. Strong economic numbers--especially GDP--are crucial. So: trade war! Force a huge economy (China) to buy more of our products. Cranks up GDP. Yay us, right?! Except China's fighting back.

One downside of the amazing @SeedSigner custom linux OS is that the overall performance is noticeably slower. This really impacts the live preview screen. Managed to find some optimizations today to move it from "Ug, this is UNACCEPTABLE!" to "hey, okay, good enough!" WOOT! 🚀

1/ 🚨New @SeedSigner v0.5.0 feature preview!🚨 Problem: #Bitcoin is complicated. How do you support advanced features but still make everything really easy for total noobs? Solution: Fully customizable configs that you can instantly swap in to change the experience!

Made good @SeedSigner progress on #payjoin . Still experimenting with different labels for the inputs and outputs. Trying out only animating the paths that matter to you as the PJ recipient (animation should continue to "PJ receive" but... bug 🫤).

Still just playing around on my dev @SeedSigner , but kinda getting close to a sensible start at a Nostr integration... (too tired tonight, but will record a demo tomorrow)

I'd like to report a crime against #Bitcoin decimal precision! I love you @BraiinsMining , but decimal place truncation is atrocious!

Proof of (metal) Work! Hammering out a @SeedSigner seed QR on one of @SeedMint21 's prototype steel plates! Fascinating experiment to see if a QR plate can be durable enough for long-term seed storage.

Progress on the @SeedSigner PSBT verification flow! The animated pictogram is looking pretty awesome now! But more importantly, the detail screens when you click "Next" are starting to come together!

🔥Yo, the PSBT overview screen is getting HOT!!!🔥 I love the clarity of @SparrowWallet 's tx explorer so I stole the idea and modified it to suit @SeedSigner 's tiny display and overall ethos. I want users to instantly understand the basics of their tx at a glance.

Don't underestimate the little victories!!! Yes, I've been able to control the screen from an esp32 before. That's nothing new. But now I'm actually starting to port the @SeedSigner code. So that means that...

If you have Bitcoin Core v22 installed, you can create Taproot wallets in @SpecterWallet ! The UI automatically adds Taproot options where appropriate (I'm using v1.7.1).

So Murch started mentoring me to help contribute to his PR. Note: He EASILY could have fixed those tests himself. But instead took the time to onboard & guide me. This will be an ongoing theme.

After all the recent talk about minimum utxo sizes, high fees, etc, I'm at a loss for the best way to **non-custodially** gift bitcoin to pre-coiners this Christmas. (i.e. $50 worth of sats sent onchain to a watch-only wallet now seems questionable) Ideas?

Look, folks, hardcore Bitcoiners are too wise and way too cool to just sit around watching the price. They have better, more important things to do. Me: 👀👀👀👀👀
