Unless I'm misunderstanding your point, nostr already has a key-reuse issue that can be solved at the same time by getting people to use signer apps, signer devices, and a key-transfer mechanism like you described.

But the key transfer mechanism should only be needed for migrating between devices or device groups. The normal functionality would come with the signer app storing the private key and using it to deal with all the interactions with the different public keys.

I'm slowly working on some big plans. If I understand correctly, making nostr pubkeys the same size as eth pubkeys would also make them work as Monero addresses. Ideally there would be 3 sizes of public key code: a small code containing the short key binary (current npub), a medium code containing the long key binary (like current eth or xmr pubkeys), and a long code containing both. Unless it's possible for a public key to simply be shortened and work with the private key without needing to be separately generated at the separate length, idk

Don't worry about the Bitcoin maxis freaking out, we'll just ignore them.

A version of nostr using Ethereum keys would easily have login compatibility with the existing nostr, because Ethereum and nostr use the same size of private keys, so nostr users could generate their new public keys, sign notes, decrypt messages etc. with the same private keys they already use

Nostr will have better web3 integration within 5 years I bet

No idea if farcaster is worth using in the mean time, it seems sus to me but I don't know your personal goals

Idk about users but measurable engagement is higher on NOSTR than either. A post with 100 likes is rare even on big Fedi servers, whereas it's not uncommon to approach several hundred on NOSTR, maybe even near 1,000 on rare occasions.

For comparison, Gab at its peak after January 6 had lots of posts with 1,000 or more likes, and the most popular ones were between 10,000 and 20,000 (It's not even 10% of that anymore, but it gives a decent measure for how active edgy alt tech can be vs how active we actually are atm.)

Currently trying to get a co-worker hooked on Berserk. He doesn't like gruesome stuff, but I think I can get him to enjoy the music from the 1997 anime.
