Each P2WPKH input is counted as 1 sigop. In addition, opcodes within a P2WSH <code>witnessScript</code> are counted identically as previously within the P2SH <code>redeemScript</code>. That is, CHECKSIG is counted as only 1 sigop, and CHECKMULTISIG is counted as 1 to 20 sigops according to the arguments. This rule applies to both native witness program and P2SH witness program. +=== Additional definitions === + +The following definitions are not used for consensus limits, but are suggested to provide language consistent with the terminology introduced above. + +==== Transaction size calculations ==== + +''Transaction weight'' is defined as ''Base transaction size'' * 3 + ''Total transaction size'' (ie. the same method as calculating ''Block weight'' from ''Base size'' and ''Total size''). + +''Virtual transaction size'' is defined as ''Transaction weight'' / 4 (rounded up to nearest integer). + +''Base transaction size'' is the transaction size in bytes with the original transaction serialization without any witness-related data. + +''Total transaction size'' is the transaction size in bytes serialized as described in [[bip-0144.mediawiki|BIP144]], including base data and witness data. + == Examples == === P2WPKH === |
