Bitcoin rotates keys.
Discussion
So, how real/serious is the re-use risk in the context of nostr?
Should nostr be improved to use something like bitcoin's BIP-32 protocol to give each user deterministic keypair chains?🤔
That's one of the first improvements I've wanted to see on nostr, but I have no idea if the re-use risk is going to matter. Keychains would also help with the risk of entering keys into all the different apps and devices people use
