Taproot

Taproot is a Bitcoin soft fork that adds Schnorr signatures and script trees so complex spending conditions appear onchain as ordinary single-key spends.

Taproot combines Schnorr signatures with a script tree so that a spend satisfying complex conditions can look identical to a simple single-key payment onchain. Only the branch actually used is revealed, improving privacy, and Schnorr enables key and signature aggregation for cheaper multisig. Taproot outputs use bech32m addresses. This makes advanced contracts smaller and less distinguishable from common spends. Our Bitcoin archive RPC decodes Taproot outputs and witness data, so you can classify Taproot spends and reconstruct their scripts from historical transactions.
