 ==Abstract==
 
-This BIP defines a sane hierarchy for deterministic multisig wallets based on an algorithm described in BIP-0032 (BIP32 from now on), purpose scheme described in 
-BIP-0043 (BIP43 from now on), and multi-account hierarchy described in BIP-0044 (BIP44 from now on).

 This BIP is a particular application of BIP43.

-Like BIP44/49/84, BIP45 unecessarily demands a single script type (here, P2SH).  In addition, BIP45 sets <code>cosigner_index</code> in order to sort the 
-<code>purpose'</code> public keys of each cosigner.  This too is redundant, as descriptors can set the order of the public keys with <code>multi</code> or have 
-them sorted lexicographically (as described in [https://github.com/bitcoin/bips/blob/master/bip-0067.mediawiki BIP67) with <code>sortedmulti</code>.  Sorting 
-public keys between cosigners in order to create the full derivation path, prior to sending the key record to the coordinator to create the descriptor, merely adds 
-additional unnecessary communication rounds.

-There is an additional multisig derivation path in use "BIP"48 (there is no real standard), which specifies:
+The second multisignature "standard" in use is m/48', which specifies:
 
 <pre>
 m / purpose' / coin_type' / account' / script_type' / change / address_index

-Rather than having a separate BIP per script type after P2SH (BIP45), vendors decided to insert <code>script_type'</code> into the derivation path (where 
-P2SH-P2WSH=1, P2WSH=2, Future_Script=3, etc). As described previously, this is unnecessary, as the descriptor sets the script.  While it attempts to reduce 
-maintainence work by getting rid of new BIPs-per-script, it still requires maintaining an updated, redundant, script_type list.
