Enum wallet::script::WitnessVersion

}

Version of the WitnessProgram: first byte of scriptPubkey in transaction output for transactions starting with opcodes ranging from 0 to 16 (inclusive).

Structure helps to limit possible version of the witness according to the specification; if a plain u8 type will be used instead it will mean that version > 16, which is incorrect.

Variants

V0

Current, initial version of Witness Program. Used for P2WPKH and P2WPK outputs

V1

Forthcoming second version of Witness Program, which (most probably) will be used for Taproot
