I have some doubts about naming in witness script/transaction.

P2SH-P2WSH (multisig)

WITNESS_SCRIPT = OP_3 <public key1> <public key2> <public key3> <OP_2>

(is it witness script or redeem script? For now I will call Witness script)

SCRIPTHASH= SHA256 (WITNESS_SCRIPT)

is it Witness script Hash or redeem script Hash?

REDEEM_SCRIPT=0020+SCRIPTHASH

is it redeem script? Maybe it's the redeem script because it is in Scriptsig. (Witness version + Witness program)

In scriptPubKey hash160 of (0020+SCRIPTHASH).

What is its name? Hash160 of ?

And We have OP_HASH160 <Redeem script hash?> OP_EQUAL

P2SH-P2WPKH

KEYHASH = hash160(<public key>)

REDEEM_SCRIPT=0014+KEYHASH

is it redeem script or witness script? For now I Will call redeem script.

In scriptPubKey hash160 of (0020+SCRIPTHASH).

What is its name? Hash160 of ?

And We have OP_HASH160 <Redeem script hash?> OP_EQUAL

P2WPKH NATIVE

WITNESS SCRIPT = hash160(<public key>)

In scriptpubkey 0014+WITNESS_SCRIPT

OP_0 <20 bytes witness script hash>

P2WSH NATIVE

WITNESS SCRIPT = <OP_2> <pubkey1><pubkey2><pubkey3><OP_3> <OP_CHECKMULTISIG>

WITNESS_SCRIPT_HASH = HASH160 (WITNESS SCRIPT)

In scriptpubkey

0020+WITNESS_SCRIPT_HASH

OP_0 <32 bytes witness script hash>

P2WPKH NATIVE and P2WSH NATIVE should be ok

P2SH-P2WSH:

  • Witness script: OP_3 <public key1> <public key2> <public key3> OP_2 OP_CHECKMULTSIG
  • Witness program: SHA256(witness script)
  • redeemScript: OP_0 <witness program>
  • Script hash: Hash160(redeemScript)
  • scriptPubKey: OP_HASH160 <script hash> OP_EQUAL

P2SH-P2WPKH (I believe that's what you meant instead of "P2WSH-P2PKH"):

  • Witness program: Hash160(public key)
  • redeemScript: OP_0 <witness program>
  • Script hash: Hash160(redeemScript)
  • scriptPubKey: OP_HASH160 <script hash> OP_EQUAL

P2WSH-P2PKH (native P2WSH, but with a P2PKH script inside):

  • Witness script: OP_DUP OP_HASH160 <Hash160(pubkey)> OP_EQUALVERIFY OP_CHECKSIG
  • Witness program: SHA256(witness script)
  • scriptPubKey: OP_0 <witness program>

Note that you should use P2WPKH instead of this.

Native P2WPKH

  • Witness program: Hash160(public key)
  • scriptPubKey: OP_0 <witness program>

Native P2WSH

  • Witness script: OP_3 <public key1> <public key2> <public key3> OP_2 OP_CHECKMULTISIG
  • Witness program: SHA256(witness script)
  • scriptPubKey: OP_0 <witness program>

  • Thanks again for your time, it's an amazing answer for me. I don't understand this script P2WSH-P2PKH the third one. I create a bash script to create P2WSH-P2PKH native (bc) where the Witness script is OP_DUP OP_HASH160 <Hash160(pubkey)> OP_EQUALVERIFY OP_CHECKSIG. But I have the last scenario (Native P2WSH), than I don't have redeem script and script hash.thanks for your advice (Note that you should use P2WPKH instead of this.) but my purpose now is to study, I don't use it :).

  • I have another question (sorry). You said "P2SH-P2WSH" redeemScript: OP_0 <witness program>. When I use signrawtransactionwithkey I need to put redeemScript in witnessScript value. Then why use the name redeemScript when I need to use in witnessScript value during signrawtransactionwithkey?

    @monkeyUser signrawtransaction* secretly doesn't really care about what you name things; it just needs to know all the scripts involved in order to sign.
