He still does not get it, but from following him over recent times I think he's getting closer

Wow. I wonder how long until they start noticing it and ring the alarm bells

Nothing stops this train. Nothing

Today I got reminded of how early we still are with Nostr. China has banned a few clients but probably hasn't realized their citizens are fleeing in droves to other clients being compiled across all continents, and that they can't stop that. Zaps will continue until moral improves. New updates every single day. Positivity and knowledge sharing. Excited for what's to come. They will never take away my optimism, and they will never take away our freedom. If you're reading this, you're a part of it. Cheers

### Huge COLDCARD Mk4 Release! Version 5.1.0

## New Features

- "MicroSD card as Second Factor". Specially marked MicroSD card must be

already inserted when (true) PIN is entered, or else seed is wiped. Add, remove and check

cards in menu: `Settings -> Login Settings -> MicroSD 2FA`

- Import TAPSIGNER encrypted backup as main or ephemeral seed, for PSBT signing.

This is a great way to **safely** use the key previously held inside a TAPSIGNER, because

the COLDCARD can take over the signing that used to be done by the card.

- Detached Bitcoin signature files for most exports.

- Files exported are now signed with a detached signature. Look for a `.sig` file

with the same name, and verify signature with your favourite Bitcoin tools.

See "Signed Exports" in `docs/msg-signing.md` for more information.

- Coldcard can now verify signed files:

- SD card and Virtual disk `Advanced/Tools -> File Management -> Verify Sig File`

- NFC `Advanced/Tools -> NFC Tools -> Verify Sig File`

- [Learn more here](https://coldcard.com/docs/sign-text-file#signed-exports)

- Related new website: [Check your Bitcoin signatures here](https://checkmsg.org/)

## Enhancements

- Address Explorer:

- Application-specific derivation paths in `Address Explorer -> Applications`

- Bugfix: Change value was ignored when generating addresses file

- Imports:

- Add import multisig wallet via Virtual Disk

- Add import extended private key via Virtual Disk and via NFC

- Import seed in compact/truncated form (just 3-4 letters of each seed word)

- Import extended private key as ephemeral seed

- Export:

- Samourai POST-MIX and PRE-MIX descriptor export options added

- Lily Wallet added

- Ability to export all supported wallets via NFC (instead of SD card only)

- Change electrum export file name from 'new-wallet.json' to 'new-electrum.json'

- Allow export of Wasabi skeleton for Bitcoin Regtest.

- Backup Enhancement:

- Option to save the backup file's encryption password for next backup. Then next

backup is quick and simple: no need to record yet another 12 words.

- During seed generation from dice rolls, enforce at least 50 rolls

for 12 word seeds, and 99 rolls for 24 word seeds. Statistical distribution check

- Single signature wallet generic descriptor export

`Advanced -> Export Wallet -> Descriptor`. Both new format with internal/external

in one descriptor `<0;1>` and standard with two descriptors are supported.

added to prevent users from generating low-entropy seeds by rolling same value repeatedly.

- Docs: Add `docs/rolls12.py` script for verifying dice rolls math for 12 word seeds.

## Bug Fixes

- Offer import/export from/to Virtual Disk in UI even if SD Card is inserted.

- Recalculate extended key saved in settings upon chain change (BTC, XTN, XRT).

- Provide correct derivation path (m/84'/1'/0') for testnet Wasabi export.

- Properly display UX checkmark only if testnet (XTN, XRT) is enabled

in `Settings- > Danger Zone -> Testnet Mode`.

These guys just keep 'em coming. Love it

Honey badger dgaf. Tick tock next block

"LN wallets rekt by Nostr zapping frenzy, push to massively extend liquidity"

5x in 1 month? 🤯

Zapping will continue until moral improves

Fair, but a lot of activity seems spam-bot driven. Looks malicious. If all clients eventually get blocked in China, but Chinese spam-bot activity continues, that's something worrying. In any case, relay operators may be able to efficiently block such spam

Welcome 🫂 try the zap feature and check out a few paid relays to increase your robustness and support the network, for example relay.exchange

And it's not even its final form yet ⚡

The Barbell my dude. Drop sets (aka pyramids) with heavy weight will get you fired up. Increase the weight until you're in the 3-6 rep range, but be careful with injuries. If youre above 85 kg try finding a spotter for saftey. Good luck 💪🏻
