Help: Unserendipitous Multisig Transaction

[luciheylel]

Please forgive for my English.

The seller did not accept the buying and the market gave me the private key of a multisig transaction.

I follow step by step this tutorial: https://www.reddit.com/r/AlphaBayMarket/comments/3tr63d/a_full_multisignature_tutorial_for_alphabay/

But in the last step, when I put the Raw Transaction, I get the following error: 64: non-mandatory-script-verify-flag (No error)

Someone help me please.

First of all, entering your private key in a website is a bad idea (ms-brainwallet) and a market that recommends doing so is suspicious to say the least.

Secondly, the error message you get is usually associated with non standard signatures. Bitcoin core wants low S signatures. If you don't know what it means, you should not use raw transactions.

It was my first transaction multisig.
then I lost my $ 400?

You should move this into the AlphaBayMarket section.

As far as whether you lost your $400, it is hard to say without more information.

Easiest way is to keep doing what you did. Every attempt has roughly a 50% chance of success as long as you re-sign

[luciheylel]

ok, I'll do it

thanks.

[luciheylel]

unsuccessfully
tomorrow try another hour.
thanks.

If your transaction doesn't change when you re-sign, you will have modify it the hard way

[luciheylel]

the transaction changes when I click re-sign
but when I finished, continues the following error:

Use the verify tab and post here what you get.

With 7 inputs, there is less than a chance in  a  100 that it works by luck. You could try out with  a wallet that supports multi sig like electrum.

Quick and dirty solution

Code:

const QByteArray Transaction::normalize ( ) const
{
  MyByteArray data;
  data.putVersion ( ).putVarInt ( countInputs ( ) );
  for ( int j ( 0 ); j < countInputs ( ); j++ )
  {
    const TxInput in ( getInput ( j ) );
    const QByteArray& script ( in.getScript ( ) );
    data.putArray ( in.get36signature ( ) )
        .putPrefixed ( xnormalize ( script ) )
        .putInt32 ( in.getSequence ( ) );
  }
  data.putVarInt ( countOutputs ( ) );
  for ( int j ( 0 ); j < countOutputs ( ); j++ )
  {
    const TxOutput out ( getOutput ( j ) );
    data.putInt64 ( out.getAmount ( ) )
        .putPrefixed ( out.getScript ( ) );
  }
  data.putInt32 ( TX_LOCK );
  return data;
}

You have to know that I am the person who is responsible for this your problem
If I can malle transactions, I should be able to 'normalize' them to correct state
