The public key you see in a taproot output is still a public key.
ok, it's a cryptographic key, and it's publicly exposed. But it's not the keypair counterpart to the private spending key, right? Or is "keypair" not meaningful in taproot?
The private key for a taproot pubkey (assuming a script) is the private key of the internal key + the hash of the script. The public key itself is computed by the sum of the internal pubkey and the "pubkey" of the hash of the script (i.e. multiply the hash by the curve generator).
Well when it's explained like that, it seems that I am at least understanding something: there are 2 keys related to the spending (private) key in taproot; the internal key and the "actual" pubkey (by "actual" I mean publicly exposed on the chain). I don't think about this kind of math often enough to really comprehend the relationships between them, despite you having just written it out
I know the words, but I can't hear the musicFor QC resistance and why hashing doesn't matter, see: https://bitcoin.stackexchange.com/questions/91049/why-does-hashing-public-keys-not-actually-provide-any-quantum-resistance
ah, now that's I was hoping for, something definitive
