==Abstract==
|
|
|
|
This document specifies <tt>raw()</tt> and <tt>addr()</tt> output script descriptors.
|
|
<tt>raw()</tt> encapsulates a raw script as a descriptor.
|
|
<tt>addr()</tt> encapsulates an address as a descriptor.

|
|
|
|
==Motivation==
|
|
|
|
In order to make descriptors maximally compatible with scripts in use today, it is useful to be able to wrap any arbitrary output script or an address into a descriptor.
|
|
|
|
==Specification==
|
|
|
|
Two new script expressions are defined: <tt>raw()</tt> and <tt>addr()</tt>.
|
|
|
|
===<tt>raw()</tt>===
|
|
|
|
The <tt>raw(HEX)</tt> expression can only be used as a top level descriptor.
|
|
As the argument, it takes a hex string representing a Bitcoin script.
|
|
The output script produced by this descriptor is the script represented by <tt>HEX</tt>.
|
|
|
|
===<tt>addr()</tt>===
|
|
|
|
The <tt>addr(ADDR)</tt> expression can only be used as a top level descriptor.
|
|
It takes an address as its single argument.
|
|
The output script produced by this descriptor is the output script produced by the address <tt>ADDR</tt>.
|
|
|
|
==Test Vectors==
|
|
|
|
TBD
|
|
|
|
==Backwards Compatibility==
|
|
|
|
<tt>raw()</tt> and <tt>addr()</tt> descriptors use the format and general operation specified in [[bip-0380.mediawiki|380]].
|
|
As this is a wholly new descriptor, it is not compatible with any implementation.
|
|
The reuse of existing Bitcoin addresses allows for this to be more easily implemented.
|
|
|
|
==Reference Implemntation==
|
|
|
|
<tt>raw()</tt> and <tt>addr</tt> descriptors have been implemented in Bitcoin Core since version 0.17.
