Title: Help using Multisig transactions Post by: Meni Rosenfeld on August 08, 2013, 05:03:03 PM I tried experimenting with Multisig and followed Gavin's example (https://gist.github.com/gavinandresen/3966071), running Bitcoin-qt v0.8.3 and using the debug console.
However, I could not get it to work. I'm using the following 3 keys, all generated in my bitcoin-qt wallet: privkey: L2JjrJNUJjLwLHcLShFsbJVt6KuWqE3svqMUrfwbNJXgssujVWgV pubkey: 02fff1a3da4dbc93d10fba4791689411a17d8308770f9cf6ea5854358441df6bc2 privkey: L1HKChJArnfKpApV7Cz7HEw9c5YKHRr9BwWtFf6f8RYmnyDXrq87 pubkey: 02a06a164106420bcc36908700af4dccc727b1e834f7424f1627623523d6751d10 privkey: L1hbxmK8H4dkk2dyHpNEN7H7RvAhaJnQUH27cdC4yAtAjQ1TNkdA pubkey: 037bac6d147cd915b74f51c0e839d5345d816b2ab70da0a862b5bef6ab6d7f1123 I created a multisig address: Code: createmultisig 2 '["02fff1a3da4dbc93d10fba4791689411a17d8308770f9cf6ea5854358441df6bc2","02a06a164106420bcc36908700af4dccc727b1e834f7424f1627623523d6751d10","037bac6d147cd915b74f51c0e839d5345d816b2ab70da0a862b5bef6ab6d7f1123"]' Went on to fund it (with the GUI).

Title: Re: Help using Multisig transactions Post by: Judson on August 08, 2013, 07:54:02 PM Yep, what dserrano5 said. The error should point you in the right direction: "Missing redeemScript".

Yep, what dserrano5 said. The error should point you in the right direction: "Missing redeemScript". I'm an idiot. Thanks.It pointed me at the right direction, but I didn't notice the case discrepancy, and since this datum was included in previous calls I assumed this kind of an error would have caused problems earlier. Title: Re: Help using Multisig transactions Post by: cbeast on August 08, 2013, 11:17:10 PM Thanks for posting this Meni. I was missing some points to understanding this from Gavin's example. I wish someone would write a step-by-step guide to creating m-of-n and nLockTime transactions.

In case you were wondering why it didn't trigger on previous calls, the redeemScript isn't needed until signing. You can stuff arbitrarily named members into that object without a problem. Those functions only check to make sure they have the parts they need, they don't reject extra stuff, they just ignore it. Title: Re: Help using Multisig transactions Post by: cbeast on August 15, 2013, 02:59:52 AM I followed Gavin's example (https://gist.github.com/gavinandresen/3966071). I created 3 vanity testnet addresses and took 1.5 test bitcoins from the faucet. I followed the example and created a 2 of 3 multisig with "value" : 0.01000000 sent from n18BfALhuJ4cXAtTDSMLSpiRjLvB6czXP8 (http://blockexplorer.com/testnet/address/n18BfALhuJ4cXAtTDSMLSpiRjLvB6czXP8) to 2MuiZNuQR2vEmCq81XRTGRSHNETUGxEWR3C (http://blockexplorer.com/testnet/tx/d27ddcaf3542094ef0cd141b7133e4398a673e291a8c6bedd5d8956937f7bdef), but it sent the entire balance of 1.5 instead of 0.1. I have not yet imported the vanity addresses into a client to recover the test bitcoins. What happened to the change?

I have not yet imported the vanity addresses into a client to recover the test bitcoins. What happened to the change? Transactions are redeemed in full. When using the raw API, you are responsible for making your own change. In this case, your inputs total 1.5 and out outputs total 0.01. The difference, 1.49, is the fee.
