chronicling the products layered upon the bitcoin protocol. dying on the crypto(graphy)-abolitionism hill.

I just set up my nostr:npub1tftc33ttam85wraffce62cgtvvjrmttquqlv6a0agtfm5nl4vues82xar5 Vault, and the user experience was incredibly smooth! πŸ”

Using Bitcoin-only hardware wallets like the nostr:npub1jg552aulj07skd6e7y2hu0vl5g8nl5jvfw8jhn6jpjk0vjd0waksvl6n8n Jade makes multisig so much easier.

You don't even need to install companion apps like Trezor Suite or Ledger Live.

Days ago, Mt.Gox transferred 141,686 BTC in preparation for the upcoming distribution.

Today, a Japanese exchange loses 4,503 BTC.

Full circle.

When nostr:npub1jg552aulj07skd6e7y2hu0vl5g8nl5jvfw8jhn6jpjk0vjd0waksvl6n8n Green upgraded from nLockTime to CheckSequenceVerify, users didn't care about adopting a new OP_CODE.

They cared about no longer needing to back up pre-signed transactions.

When wallets add support to covenants, most users won't care if it's CTV, CCV, or CAT...

Introducing the Humane Bitcoin Wallet ✨

Hardware wallets should feel more human:

πŸ—£οΈ Read your seed phrase out loud

πŸ‘• Pin your life savings to your shirt

πŸ€– Select and label UTXOs with your voice

🀌 Verify transactions with your bare hands

Not your pin, not your coins!

every time a mobile wallet asks you to back up 24 words instead of 12, a honey badger dies 🦑

Bolt Cards on the Google or Apple Wallet would be dope

Hardware wallets are getting heavier βš–οΈ

2014: Trezor One β†’ 12g

2016: Ledger Nano S β†’ 16g

2018: Trezor Model T β†’ 22g

2019: Ledger Nano X β†’ 34g

2023: Ledger Stax β†’ 45g

2024: Bitkey β†’ 65g

Beware of security nihilism when reacting to nostr:npub1tcnvkw8fu29zspw54tuhfrk0tkzn6qdupmc45slt4zmase3dzqask6ctu0 .

nostr:npub1xyd5ja34s4nk0l6urnh69wx9ep6uuxz2ujrkm2f8n6pfhgqa6y5s2xn6n2 raised a valid point when introducing his 2-of-2 seedless cloud backup scheme:

Funny how 24-word seed phrases feel safer than 12.

(probably a cognitive bias 🧠)

Doubling the word count offers no real advantage. πŸ€·β€β™‚οΈ

And it's twice as cumbersome to backup.

12 is enough, don't waste your time with 24.

It's been nearly a year since MicroStrategy announced their Lightning Platform with rewards and more. Haven't heard any updates since. Does anyone know if they're still working on it?

nostr:npub1864jglrrhv6alguwql9pqtmd5296nww5dpcewapmmcazk8vq4mks0tt2tq launched a leaderboard ranking countries by merchant adoption. Cool to see Brazil πŸ‡§πŸ‡· at the top!

Bitcoin is for enemies.

Bitcoin is for people like Nayib Bukele.

One day, our great-grandchildren will hear stories about the fiat era.

They'll study history through our memes.

They'll question why humanity tolerated central banks for so long.

They will own everything and be happy. πŸ₯Ή

Feb 2024 - Sold 3,000 Quantum Cats for 0.1 BTC each

the world if women understood that men also get mansplained by other men

the best affiliate program for bitcoin creators is owning bitcoin

fix email spam... fix the world

I was today years old when I learned that hovering over "Taproot" on nostr:npub18d4r6wanxkyrdfjdrjqzj2ukua5cas669ew2g5w7lf4a8te7awzqey6lt3 shows this:
