This new proposal basically sticks coin type on the public\nderivation side of things so that I could generate litecoin or darkcoin\nmultisigs without your permission...\n\nKefkius,\n\nThis BIP seems like a good fit for multi-currency wallets based on\nmultisig. So kudos for putting it in writing.\n\nHowever, I don't know if this is really a BIP thing. It's not improving\nBitcoin (Bitcoin Improvement Proposal... remember?), in fact, by definition\nit is improving altcoin usability.\n\nFor that reason alone I will say I disagree for a BIP for this.\n- Jona\n\n\n2015-04-08 16:46 GMT+09:00 William Swanson \u003cswansontec at gmail.com\u003e:\n\u003e\n\u003e It's not really clear why this is better than BIP 44 as it already\n\u003e stands. You have the same fields, but they are just in a different\n\u003e order. Couldn't you just use the existing BIP 44 hierarchy, but add\n\u003e the convention that \"wallet/account N\" is the same wallet in each\n\u003e supported currency?\n\u003e\n\u003e For example, if I have a wallet called \"business expenses\", which\n\u003e happens to be wallet m / 44' / 0' / 5', for Bitcoin, then the same\n\u003e wallet would be m / 44' / 3' / 5' for Dogecoin, and m / 44' / 2' / 5'\n\u003e for Litecoin.\n\u003e\n\u003e I am trying to think of examples where your proposal is better than\n\u003e BIP 44, but I can't think of any. Even backup recovery works fine. I\n\u003e assume that your idea is to continue iterating over the different\n\u003e wallet indices as long as you are finding funds in *any* currency.\n\u003e Well, you can still do that with BIP 44. The fields are in a different\n\u003e order, but that doesn't affect the algorithm in any way.\n\u003e\n\u003e Maybe you have some deeper insight I'm not seeing, but if so, you need\n\u003e to clearly explain that in your motivation section. The current\n\u003e explanation, \"This limits the possible implementations of\n\u003e multi-currency, multisignature wallets,\" is pretty vauge. Also, there\n\u003e is nothing in this spec that addresses the multisignature use-case.\n\u003e The BIP 45 spec does a lot of extra work to make multisignature work\n\u003e smoothly.\n\u003e\n\u003e I'm not trying to criticize your proposal. I'm just trying to\n\u003e understand what it's trying to accomplish.\n\u003e\n\u003e -William Swanson\n\u003e\n\u003e\n\u003e On Wed, Apr 8, 2015 at 12:05 AM, Kefkius \u003ckefkius at maza.club\u003e wrote:\n\u003e \u003e I have a potential BIP, \"Multi-Currency Hierarchy For Use In\n\u003e \u003e Multisignature Deterministic Wallets.\" I'm requesting discussion on it,\n\u003e \u003e and possibly assignment of a BIP number.\n\u003e \u003e\n\u003e \u003e It's located in this github gist:\n\u003e \u003e https://gist.github.com/Kefkius/1aa02945e532f8739023\n\u003e \u003e\n\u003e \u003e\n------------------------------------------------------------------------------\n\u003e \u003e BPM Camp - Free Virtual Workshop May 6th at 10am PDT/1PM EDT\n\u003e \u003e Develop your own process in accordance with the BPMN 2 standard\n\u003e \u003e Learn Process modeling best practices with Bonita BPM through live\nexercises\n\u003e \u003e http://www.bonitasoft.com/be-part-of-it/events/bpm-camp-virtual-\nevent?utm_\n\u003e \u003e source=Sourceforge_BPM_Camp_5_6_15\u0026utm_medium=email\u0026utm_campaign=VA_SF\n\u003e \u003e _______________________________________________\n\u003e \u003e Bitcoin-development mailing list\n\u003e \u003e Bitcoin-development at lists.sourceforge.net\n\u003e \u003e https://lists.sourceforge.net/lists/listinfo/bitcoin-development\n\u003e\n\u003e\n------------------------------------------------------------------------------\n\u003e BPM Camp - Free Virtual Workshop May 6th at 10am PDT/1PM EDT\n\u003e Develop your own process in accordance with the BPMN 2 standard\n\u003e Learn Process modeling best practices with Bonita BPM through live\nexercises\n\u003e http://www.bonitasoft.com/be-part-of-it/events/bpm-camp-virtual-\nevent?utm_\n\u003e source=Sourceforge_BPM_Camp_5_6_15\u0026utm_medium=email\u0026utm_campaign=VA_SF\n\u003e _______________________________________________\n\u003e Bitcoin-development mailing list\n\u003e Bitcoin-development at lists.sourceforge.net\n\u003e https://lists.sourceforge.net/lists/listinfo/bitcoin-development\n\n\n\n\n--\n-----BEGIN PGP PUBLIC KEY BLOCK-----\nComment: http://openpgpjs.org\n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\nSpe3vsHZr6CqFg==\n=/vUJ\n-----END PGP PUBLIC KEY BLOCK-----\n-------------- next part --------------\nAn HTML attachment was scrubbed...\nURL: \u003chttp://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20150409/a0f5b1a6/attachment.html\u003e"}
