Output script descriptors

Also covering Descriptors

Output script descriptors are strings that contain all the information necessary to allow a wallet or other program to track payments made to or spent from a particular script or set of related scripts (i.e. an address or a set of related addresses such as in an HD wallet).

Descriptors combine well with miniscript in allowing a wallet to handle tracking and signing for a larger variety of scripts. They also combine well with PSBTs in allowing the wallet to determine which keys it controls in a multisig script.
