A 32-byte public key format that includes only the X coordinate, used with Schnorr signatures and Taproot.
Taproot and BIP340 use x-only public keys (no parity byte) for cleaner key aggregation and smaller data. Parity is inferred during verification.
"A P2TR output commits to an x-only internal key; spending reveals Schnorr signatures without the extra Y-parity bit."
All terms and definitions may update as the Cryptionary improves.
