Taproot Script-Path Spends

protocol.taproot-script-path-spends

A Taproot script-path spend reveals one committed Tapscript leaf, the witness items that satisfy it, and a control block proving that leaf belongs to the output key. Nodes recompute the Taproot commitment before executing the revealed script, while every unused branch remains hidden.
