What if the multi-parties never claim the coins? Do the sender have the capability to cancel the contract in order to free the coins?

Is there something in bitcoind that would allow me wrap this with P2SH?

flybird365, i don't think so. one way around could be to sign a nlocktime transaction releasing the coins if they are not spent by a certain date.

how can i import the multisign-addr to the qt wallet,or when the qt wallet will support the multisign-addr transaction?
I got a return:TX rejected (code -22) vwhen sendrawtransaction,what is the matter?

How do you obtain 'scriptPubKey' when you are the second party signing the transaction, and may not have known how the MultiSig address was originally created?

Found my answer --> "decoderawtransaction"

Hi there,

thank you for your great article.

I tried to do it step by step, but when submitting the transaction, I receive the following:

That is, the transaction seems to be valid.
Please would you mind providing some kind of help?

Thank you very much

Hello,

How can I create RAW TX and sign it with a few addresses

multisigAddress1
multisigAddress2

Any example ?

Hi, Before decoderawtransaction you need to sendrawtransaction and use the output for decoderawtransaction. It solves the error: {"code":-26,"message":"18: bad-txns-inputs-spent"} error.

Hi,

the above example does not work anymore. Can you please help.

1. multisig addresses when created do not start with 3 anymore

2. I can not sign the transaction no matter what I do

Please help, thanks.

As part of a class assignment I created a multi sig address and sent bitcoin to it but now I cannot find the transaction or the coin. Obvious novice error but it was not on test so ....Any help would be appreciated.

@lfcook11 try searching your bash history for the commands that created the address and redo them. You should get the same address.

@lfcook11 (and other people coming here in the future) If you remember the date and the amount you sent, you can use a block explorer search engine.

I Googled "search bitcoin transaction by date" and found this Stack Overflow answer:

Suppose I want to search for a transaction of exactly 445 BTC in the date range 27 July 2013 and Aug 3rd 2013 ... is there an (online?) tool that has this kind of search capabilities?

Blockchair allow you to query the bitcoin blockchain with lots of parameter such as date, BTC output amount, fee amount etc...

Here is your request: https://blockchair.com/bitcoin/transactions?q=time(2013-07-27..2013-08-03),output_total(44500000000)#
