Taproot

Taproot is a proposed soft fork change to Bitcoin that will allow payments to schnorr public keys that may optionally commit to a script that can be revealed at spend time.

Coins protected by taproot may be spent either by satisfying one of the committed scripts or by simply providing a signature that verifies against the public key (allowing the script to be kept private). Taproot is intended for use with schnorr signatures that simplify multiparty construction (e.g. using MuSig) and with MAST to allow committing to more than one script, any one of which may be used at spend time.
