This is the best hardware wallet I ever used. COLDCARD Q1.

Is Twitter/X still a thing for you?

Is nostr still a thing for you?

I'm a big fan of bare metal.

And you complain about the $1.92 to move your unspent output into one of the next blocks.

Do you feel safe where you live?

What model?

Fixed subscription per month or per usage?

And what about the relsy?

It's not about the service provided: Replace "Whirlpool" with your option of choice!

Replace wine with sparkling water, then replace sparkling with still water.

I stopped eating that crap years ago.

Yo, how did you get the /ck shortcut link?

👉 Wifi (2.4Ghz) and Bluetooth support

👉 ESP-Now protocol for device-to-device radio, Internet access via your 2.4Ghz Wifi access point

👉 Programmed in Micropython, all source fully-available; completely field upgradable

This page https://bip329.org offers a comprehensive overview of #BIP329, proposed by nostr:npub1hea99yd4xt5tjx8jmjvpfz2g5v7nurdqw7ydwst0ww6vw520prnq6fg9v2, creator of SparrowWallet.

You'll find information about the current status and adoption progress, highlighting the significance of this proposal.

In the world of #Bitcoin, the cornerstone of your privacy lies in labels and coin control.

While techniques like CoinJoins and Layer 2 (L2) can enhance your privacy, without a comprehensive understanding of your Unspent Transaction Outputs (UTXOs), you may not have a complete picture of your Bitcoin holdings and financial activities.

📢 Happy to announce the official release of `python-bip329` version 0.0.3!

Key Features: 1️⃣ 2️⃣ 3️⃣ 4️⃣ ⬇️

1️⃣ BIP-329 Label Parsing

Parse #Bitcoin wallet labels with ease from a .jsonl file by validating line by line.

2️⃣ Label Writing & Encryption

Write valid .jsonl files in plain text, or encrypt label files securely within a 7z archive with AES-256 encryption.

3️⃣ Decryption

Decrypt encrypted 7z archive effortlessly.

4️⃣ Robust Testing

Is this a pipe gun?

Repro build of the COLDCARD firmware v5.1.3 👍

This process checks the compiled binary against the binary published by Coinkite. If you see the "SUCCESS." message, the binaries are identical, except of 64 bytes (Coinkite's signature).

These bytes are removed using "TRIM_SIG = sed -e 's/^00003f[89abcdef]0 .*/(firmware signature here)/' " in the Makefile.

https://github.com/Coldcard/firmware/blob/f7af32cce7fee04e8b2d1b305b213efb68c2cf3f/stm32/shared.mk#LL250C14-L250C84

If you wonder why these checksums of the compiled files are different, compare to the binary you have downloaded from https://coldcard.com/downloads/, it's exactly due to those 64 trimmed signature bytes.

Just in case you want to send me some sats:
