Without further context, I would read this as: don't doxx your customers on the blockchain unless you're able to delete every copy of it. I.e. don't put other peoples data on the blockchain.

Which in my opinion includes forcing customer to do a satoshi test. Or encouraging them to reuse addresses. Looking at you, Travel Rule...

We need to make sharded nsecs the default for Nostr.

Amethyst partially signs with its share of the nsec and sends to Amber. Amber can only finish the signature or reject. Amber should not be able to reassemble the nsec from any event from Amethyst (or any other app).

Now repeat this for every single Nostr app.

No single app has the full nsec. The only way to "leak" an nsec is to break into the code of both apps at the same time.

Frost does that. But for singing only.

We also need sharded encryption and decryption schemes.

I keep hearing about people's lightning nodes having to force close things and it sounds like they are losing a lot of sats somehow. Is that right? Is lightning somehow a fucked protocol? Please forgive and correct my ignorance on this topic. I'm interested not in the gory details, nor summary opinions, but in correct succinct explanations.

Breathing in and out is like playing ping pong on a socket connection to life.
