See:\n  https://moqups.com/gavinandresen/no8mzUDB/\n  https://moqups.com/gavinandresen/no8mzUDB/p:ab18547e0\n... etc.  for a UI mock-up.\n  There needs to be some protocol so all participants in a multisig wallet\ncontribute keys (actually, we should just assume everybody uses BIP32 HD\npublic keys so we get privacy from the start).\n\nMulti-person shared wallets, escrows, and \"wallet protection service\"\nwallets (which might be protected with two-factor authentication) are\ndifferent use cases and probably use slightly different protocols (and will\nprobably need different BIPs eventually).\n\n\nb) Gathering signatures for a multisig spend. Here is where the payment\nprotocol is useful; the PaymentRequest message should be passed around so\nall participants know what is being paid for, and maybe a partially-signed\nPayment message is where the signatures are gathered (or maybe the\nsignatures are sent separately and one of the participants creates and\nsubmits the Payment and gets the PaymentACK... \"to be designed\").\n  See:\n    https://moqups.com/gavinandresen/no8mzUDB/p:a7e81be96\n    https://moqups.com/gavinandresen/no8mzUDB/p:af7339204\n... for UI mock-up for the multi-person-spend case.\n\nAnd maybe a protocol for \"I don't want to be part of this multisig any more\n/ I lost control of my private key don't trust me in this multisig any\nmore\".\n\n\n\nOn Mon, Mar 10, 2014 at 8:14 PM, Jeff Garzik \u003cjgarzik at bitpay.com\u003e wrote:\n\n\u003e All of that only melds with the payment protocol under an extremely\n\u003e expansive definition of \"payment.\"  The payment protocol is really\n\u003e geared towards a direct one-to-one relationship....\n\n\n\n\u003e\n\u003e\n--\nGavin Andresen\n-------------- next part --------------\nAn HTML attachment was scrubbed...\nURL: \u003chttp://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20140310/1ce818ae/attachment.html\u003e"}
