Do I waste money on a bitaxe or waste money on an S19?

Spent some quality time with Bitcoiners/Freedom Tech/Pro-Liberty people today. Very encouraging! 🫂

No swearing, I just do resonate tuning, which sounds kinda like om chanting in hinduism. Don’t really know why that is just what comes out.

First round plunge at 45F for 3:30 mins

then sauna at 170F for 20 mins,

Second round plunge for 5 mins,

Then sauna again for 15 mins.

Proud of myself for doing the cold plunge, been wanting to integrate that into my sauna routine.

I happen to be using Coracle via NIP-46 login right now, actually. I generally use Alby as my signer extension on my desktop, but I am testing out Amber's NIP-46 signing option for a review I am writing.

I also use Amber for all signing on my mobile Nostr clients, using NIP-55 whenever possible.

I don't log into any clients that require my nsec whatsoever.

I think that's about the best we can do at this point. If NIP-46 signing was just a bit more reliable, I would go to just using Amber, and not use a browser extension either.

There are currently 3 ways to sign without entering your nsec into the client.

1. NIP-07 via browser extension. Almost all web apps now support this method, and it has a pretty good user experience, but users may not be comfortable with storing their keys in a browser extension.

2. NIP-46 first used via NsecBunker, but now also available for use via nsec.app, Amber signer on Android, and most recently with a unique method of splitting your key between three remote custodians via njump's new onboarding app. However, NIP-46 support is much less common among clients, and it often just seems to not work, even if it is supported.

3. NIP-55 Android Signer which is only available via Amber at this time. It is my personal favorite option, as it is very user friendly and your keys are stored locally by an open-source app. However, there are even less options for this signing method among clients than there are for NIP-46.

We do not have any way to store keys offline, because your key is needed to sign EVERYTHING on Nostr. It's similar to the reason keys cannot be stored offline for Lightning. We would need to have the ability to generate child-keys that can be used instead of the parent-key, and which can be revoked if they are compromised, before we would have the ability to store the parent-key offline, and use the child-key for regular event signing.

I have a lot of learning about Bitcoin still to do. Just used Venice AI to help understand what FROST is.

FROST Xpubs, or Flexible Round-Optimized Schnorr Threshold (FROST) extended public keys (Xpubs), refer to a cryptographic concept used in multi-signature (multisig) wallets and other applications.

In a FROST system, Xpubs are used to generate public keys for a group of users, typically in a multisig wallet scenario. These public keys can be used to receive funds, but the actual spending of those funds requires the cooperation of multiple users.

The key features of FROST Xpubs include:

1. **Flexible**: FROST allows for a flexible threshold, meaning that a subset of users can authorize a transaction, rather than requiring all users to sign.

2. **Round-Optimized**: FROST is designed to minimize the number of rounds required for the multisig protocol, making it more efficient.

3. **Schnorr Threshold**: FROST uses the Schnorr signature scheme, a type of digital signature algorithm, to enable threshold signatures.

4. **Extended Public Keys (Xpubs)**: Xpubs are used to derive public keys for the group, allowing for the creation of new addresses without revealing the underlying private keys.

FROST Xpubs provide a secure and efficient way to manage multisig wallets and other applications that require cooperative key management. They enable flexible and robust security protocols, while minimizing the complexity and computational overhead associated with traditional multisig schemes.

nsecbunker is good too

We really don't have a good way to store your nsec offline yet, so anything that is FOSS & vetted to store in the local cache is the best we have rn, extensions too

As of right now

Extensions

browser or mobile like Amber [only available on android])

Amber on Android

Alby extension addon in web browser

were already saying it
