+
+==Abstract==
+
+This document specifies <tt>pk()</tt>, <tt>pkh()</tt>, and <tt>sh()</tt> output script descriptors.
+<tt>pk()</tt> descriptors take a key and produces a P2PK output script.
+<tt>pkh()</tt> descriptors take a key and produces a P2PKH output script.
+<tt>sh()</tt> descriptors take a script and produces a P2SH output script.
+
+==Copyright==
+
+This BIP is licensed under the BSD 2-clause license.
+
+==Motivation==
+
+Prior to the activation of Segregated Witness, there were 3 main standard output script formats: P2PK, P2PKH, and P2SH.
+These expressions allow specifying those formats as a descriptor.
+
+==Specification==
+
+Three new script expressions are defined: <tt>pk()</tt>, <tt>pkh()</tt>, and <tt>sh()</tt>.
+
+===<tt>pk()</tt>===
+
+The <tt>pk(KEY)</tt> expression can be used in any context or level of a descriptor.
+It takes a single key expression as an argument and produces a P2PK output script.
+Depending on the higher level descriptors, there may be restrictions on the type of public keys that can be included.
+Such restrictions will be specified by those descriptors.
+
+The output script produced is:
+<pre>
+<KEY> OP_CHECKSIG
+</pre>
+
+===<tt>pkh()</tt>===
+
+The <tt>pkh(KEY)</tt> expression can be used as a top level expression, or inside of a <tt>sh()</tt> descriptor.
+It takes a single key expression as an argument and produces a P2PKH output script.
+Depending on the higher level descriptors, there may be restrictions on the type of public keys that can be included.
+Such restrictions will be specified by those descriptors.
+
+The output script produced is:
+<pre>
+OP_DUP OP_HASH160 <KEY_hash160> OP_EQUALVERIFY OP_CHECKSIG
+</pre>
+
+===<tt>sh()</tt>===
+
+The <tt>sh(SCRIPT)</tt> expression can only be used as a top level expression.
+It takes a single script expression as an argument and produces a P2SH output script.
+<tt>sh()</tt> expressions also create a redeemScript which is required in order to spend outputs which use its output script.
+This redeemScript is the output script produced by the <tt>SCRIPT</tt> argument to <tt>sh()</tt>.
+
+The output script produced is:
+<pre>
+OP_HASH160 <SCRIPT_hash160> OP_EQUAL
+</pre>
+
+==Test Vectors==
+
+TBD
+
+==Backwards Compatibility==
+
+<tt>pk()</tt>, <tt>pkh()</tt>, and <tt>sh()</tt> descriptors use the format and general operation specified in [[bip-0380.mediawiki|380]].
+As these are a wholly new descriptors, they are not compatible with any implementation.
+However the scripts produced are standard scripts so existing software are likely to be familiar with them.
+
+==Reference Implemntation==
+
+<tt>pk()</tt>, <tt>pkh()</tt>, and <tt>sh()</tt> descriptors have been implemented in Bitcoin Core since version 0.17.
