There is a typo on line 55. Think you want the private key here, not the public one. |

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 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: bitcoin-cli -regtest sendrawtransaction 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 However, That is, the transaction seems to be valid.

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. |

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. |

Some questions :
If I send the funding transaction long before creating the redeeming transaction do i still need the scriptpubkey,txid and the redeemingscript? or do i only need the txid?
am i able to spend from an adress with another txid than the funding transaction with all privatekeys?
Do i have to call listunspent for txids or is there a function with which i can create new ids?
