Hello all,
Just wanted to give an update on progress for the "bip48" proposal.
There was some discussion on Twitter between a few multi-sig wallet devs: https://twitter.com/fullynoded/status/1339374947228008448?s=21
A few key points were brought up:
1. We should not define a `script_type` as a path level
The explicit purpose of this BIP is to define an already existing standard that is used in practice across multi-sig wallets. In order to do that we must define a script_type in the path otherwise "loss of funds" could occur and backwards compatibility broken.
2. Another point brought up was that no-one uses the legacy derivation path m/48'/0'/0'/1', in practice all "legacy" p2sh multi-sig wallets use bip45.
I agree and have removed all references to legacy p2sh derivations in the proposed bip.
3. We could possibly include a defined "wild card" in the script_type level to define any future address types (e.g. taproot)
I agree this could be useful and think Ben Kaufman's suggestion of using m/48'/0'/0'/1' for this purpose makes sense, however I also think a future multi-sig standard for new address types may well be suited for a different BIP which could also address concern #1 around including `script_type` at all.
Therefore I have not yet added any mention of "wild card" in the proposed bip but kept strictly to p2sh-p2wsh and p2wsh derivations as used in modern day wallets.
I have create a PR https://github.com/bitcoin/bips/pull/1072 so that anyone may easily comment on it and any concerns can be raised.
I think the community needs this and it is well over due. I have gotten positive feedback and support from other devs.
Feedback welcome.
Cheers,
Fontaine
