Title: Finding "Half-Signed" Transactions Post by: AsymmetricInformation on March 13, 2013, 02:20:36 PM Hello, I'm curious about something and could not find the answer.
Situation: "A" signs a 2 of 2 multisig transaction, sending to "B". It still needs to be also signed by a third person "C" to actually go through, but C doesn't know who A and B are, and is never told about this transaction. 1] Can C use the blockchain to find a broadcasted half-signed (signed only by A) transaction? Ie is a "find all mutisig transactions that pubkey X still need to sign with its private key" operation possible? 2] Can A write a transaction that has two outputs, one multisig 2 of (A, C) to (B), and another single-sig to C (containing a tiny amount) to aid in this purpose? C sees that he has received funds, goes to the originating address, and signs the yet-to-be fully signed multisig transactions. Is it even possible to broadcast "half-signed transactions"? Thank you!

They might become useful with some protocol extension for which numerous suggestions float around here. Title: Re: Finding "Half-Signed" Transactions Post by: AsymmetricInformation on March 13, 2013, 03:07:40 PM Darn. Ok thanks for the reply.
