Does nostr have a way to ask a relay to provide a signed receipt of a message. Do relays have public keys at all?

That’s literally what it is lmao. I was testing what happens when you sign something with images with amber and chose something from my photo library that wasn’t a family photo and found WhatsApp auto-saved aunt calibre bible quote.

It's not looking ethbros. I've been doing some technical analysis on ETH/BTC. It turns out that maybe ETH and all "utility tokens" have no fundamental value and it just took an unusually long time for the market to begin adjusting them towards zero.

Oh interesting OK. So this is broadcast and then you send out deletion for it when the draft is no longer needed?
It seems to happen even if I don't close a note though..

....what's a draft note?

Technical nostr question: How come when I make a note Amethyst asks me to sign an event deletion.

Still waiting for the pro-kamala nostr corner to develop. Even Pro-trump is pretty weak here.

This explained some pretty deep feelings I was never able to articulate.

Ah thanks. I didn't catch that idea in my skim listen.

Making Bitcoin more private with CISA

This is a very peculiar topic since CISA doesn't make anything more private.

Can anyone recommend some good nostr talks/podcasts that discuss technical goings on and explain architecture of nostr etc.

2024-08-27 21:12:37

Oh someone's working on FROST nostr already!

I tried to order one of these but I goofed the address, cancelled it and they wouldn't let me reorder because of item limits :(

Any talks you recommend in particular?

Thinking about opportunities for FROST and nostr integration.
1. It should be easy to generate a FROST key with a bunch of people on nostr. But this creates a new thing for everyone to back up (the key share).
2. Maybe we can avoid this with the recovery feature of the FROST keygen WIP BIP. Basically you have your share encrypted to a (smallish) encrypted blob in a nostr note so just with your nostr nsec it should be possible to recover it. Maybe there is some way to pay relays to keep a note into the future.
3. Apart from keygen nostr relays might be used to broadcast signature requests to notify people with other keys that there's something to do. Even an encrypted chatroom among share holders.
4. I'm not sure how this fits in with frostsnap. Frostsnaps could have their own npubs for keygen but I don't really want to back them up. So I think you'll be forced to write down your share backup as usual.
5. It would be good if signing was still one round so I guess presharing nonces would be done via nostr too.

I enjoyed participating in this episode. @npub1az9…m8y8 is great at bringing together the quiet builders and deep thinkers in Bitcoin.

See FAQ: https://darkskippy.com/faq.html
24 words needs twice as many signatures as 12. 24 words with strong passphrase needs twice as many as 24 words without one.

If the attacker has the xpub then it's definitely much easier and it should be possible in one sig. Your aglo looks right. You can also do it in a single address reuse.

The reason we thought this attack was notable and worth disclosing is that it doesn't depend whatsoever on the user's behavior or precautions (i.e. not giving out xpubs).

Seed signer is easy to load malicious firmware on. It is also only possible to use it airgapped. It has everything to do with our point.
