So it looks like with FROST you can have a set of keys distributed across multiple devices or people, and then you can progressively change that group -- add new keys and remove old keys -- while still keeping your same npub forever.

Anywhere I can read up on this?
This is what I’ve been waiting for🤩
what the, really? seems magic. I assumed it would have been a fixed set.
Even the illusion is part of reality, Will.

it’s insane. still wrapping my head around it but if you have a threshold of signers agree, they make changes to the setup without having to regenerate anything
just imagine: you have a hardware device get compromised/lost and you can replace it without needing to change anything 🤯
Wtf
Yup you just have to be sure the old shares are properly deleted
ah, so perhaps not useful in the “someone got a hold of one of my devices” scenario
As long as you're confident a quorum of signers properly delete old shares then you're good. For example, someone could steal one device in a 2of3 and the other 2 signers you control can generate a new set of 3 shares and properly delete their two shares. The thief's share is pointless then.
nice, thanks for the explanation! getting really excited to see a frost wallet in the wild
When will exchanges support bech32m? Until then it is risky for a wallet to be taproot-only. https://whentaproot.org/
exchanges only need to support sending to taproot addresses, which is an almost trivial change.
feels like we should be advocating more for them to do this, if that indeed is what’s holding back innovation
We have advocated. See the advocacy website I linked. And spoken to PMs and engineers at some of the companies. They don't see it as a business priority.
