P2TR
P2TR is Bitcoin's Taproot output type, committing to a public key and optional hidden script tree.
- Also known as
- Pay-to-Taproot
P2TR (Pay-to-Taproot) is an output type that pays to a Schnorr public key, with the option to spend either via a key path (single signature) or a script path (revealing one branch of a Merkleized script tree).
P2TR can improve privacy and efficiency because common spends reveal only a public key and signature, while uncommon fallback scripts remain hidden. It is a Bitcoin Taproot/SegWit output type, so users should not assume the same address or witness format exists on non-Taproot networks.
