This sets up a way\nto negotiate the address and abstract away the nasty details of finding\npublic keys from bitcoin addresses, and provides a nice clean way for\nredemption abstracting away the long strings of hex.\n\nFor redemption, I think as each party signs the tx if the script returns\ntrue, it would be acceptable to just go right ahead and broadcast it, or\nmaybe as you suggest all signatures go back to the initiating party and\nthey do the final work.\n\nI very much like the idea of assuming each party uses HD wallets, that\ncertainly simplifies things greatly. I also like the use of email addresses\nas a negotiation medium, but I also wonder if this could be made agnostic\nin any BIP proposal so it could work with other communication mediums like\nbitmessage for example (just forward thinking anonymity a little).\n\nI definitely think there is a need for a protocol because multisig,\nregardless of the application has two technically involved steps:\nnegotiation of an address, and redemption of any subsequently encumbered\nfunds. A protocol would enable different wallet implementations to\nparticipate in such a transaction and make wide-spread use much more likely\nand possible.\n\nDrak\n\n\nOn 11 March 2014 01:15, Gavin Andresen \u003cgavinandresen at gmail.com\u003e wrote:\n\n\u003e Multisig is orthogonal to the payment protocol (but payment protocol is\n\u003e needed first).\n\u003e\n\u003e There need to be protocols for:\n\u003e\n\u003e a) Establishing multisig wallets of various sorts.
