I got it because the base secret key of it is just the hash of a private key and it uses a musig2 schnorr signature. The rest is not consensus.

THE REST IS NOT CONSENSUS.

Only thing the consensus cares about is the Musig2 schnorr signature is valid.

The rest are just a type of on-chain anchoring for rollups, essentially.

I'll fight anyone who doeen't agree that's the essential, central point about what taproot is. ROLLUPS.
