I was trying to add another branch of OP_ELSE to mimic Gmaxwell's CoinSwap but I don't really know how to skip the previous OP_ELSE and run the next OP_ELSE. Do you know how to do it?

I think I remember reading that you can nest the OP_IFs - in which case you would do something like this:

<cond1>
OP_IF
<cond2>
OP_IF
...
OP_ELSE
...
OP_ENDIF
OP_ELSE
...
OP_ENDIF


Hi, many thanks for the clue. I managed to construct the following structure

Quote
OP_IF
OP_IF
OP_DUP OP_SHA256 <HASH> OP_EQUAL
OP_DROP
OP_DUP OP_HASH160 <pubkeyhash2> OP_EQUALVERIFY OP_CHECKSIG
OP_ELSE
<cltv> OP_NOP2 OP_DROP
OP_DUP OP_HASH160 <pubkeyhash1> OP_EQUALVERIFY OP_CHECKSIG
OP_ENDIF
OP_ELSE
2 <pubkey 1> <pubkey 2> 2 OP_CHECKMULTISIG
OP_ENDIF
The structure probably is the first few steps of Gmaxwell's Coinswap. I am not sure whether this can be called as atomic. Basically the tx can be redemed by 3 different ways:
- secret value + sig2
- sig1 + pubkey1 after certain CLTV
- sig1 + sig2 (in 2-of-2 multisig)

This Bitcoin Script IDE might be useful, but there might be a bug in it.

http://www.cs.princeton.edu/~tongbinw/bitcoinIDE/build/editor.html

The following thread discusses signing transactions on the testnet, and using the IDE to track down problems, but one of the final comments says it was giving inconsistent results with known good values. However, the IDE might have been updated since then.


Last time I checked, it is still buggy. This one https://webbtc.com/script is one of the best so far, despite it does not work lately.

Hmm... I have nearly got there (perhaps):

Code:
0100000001bbc6c76fd91bee5badfb0746204adba70efceb04f21a270de566827dbc34e8410000000085002103d30f361b0d5dacba61a56db0903fe32244b5616f950cac1081694e81148dd7594c6076a820c775e7b757ede630cd0aa1113bd102661ab38829ca52a6422ab782862f26864687637576a91401d7295f243a3a6d26516b54e4e6f51278d376b588ac6703ac9a09b17576a914b6a7c89a6774de8c88d0b7a4043a6645983a479588ac68000000000140420f00000000001976a9148a7dd4d0e29f50f989dd2b97d463d706a7ef0c7b88ac00000000

When I decode this I am seeing the following (which I think looks fine):
Code:

Are you trying to redeem the CLTV block? BX decodes the tx as follows.

Quote
transaction

    hash b6ae7d90587b27adef7c36571cc1fdf4fbe04c77d2a3113a2239188285f581cf

                index 0
            }

    }

            value 1000000
        }
    }
    version 1
}

I wonder why there is a zero there.

Yes - I am trying to do the CLTV redeem (but without a sig it will never work of course).

I wonder why there is a zero there.

That is where the sig should end up (except that it won't sign the tx for me). My understanding is that you can leave a zero as a place-marker in the raw tx to later replace with the signature (assuming it would agree to sign the tx for me which it won't).

You can omit the zero with this version:

Code:
0100000001bbc6c76fd91bee5badfb0746204adba70efceb04f21a270de566827dbc34e84100000000842102d1570ab314b7b32ffe76f31232805a727d05119958d14b0b8aff9df5709676884c6076a820c775e7b757ede630cd0aa1113bd102661ab38829ca52a6422ab782862f26864687637576a91401d7295f243a3a6d26516b54e4e6f51278d376b588ac6703ac9a09b17576a914b6a7c89a6774de8c88d0b7a4043a6645983a479588ac68000000000140420f00000000001976a9145817f2d63208327c21da272a3bb037c3d9ec026988ac00000000

But without being able to sign the tx it doesn't really help me.

So using that version if I try signrawtransaction I get the following output:
Code:
{
    "hex" : "0100000001bbc6c76fd91bee5badfb0746204adba70efceb04f21a270de566827dbc34e84100000000842102d1570ab314b7b32ffe76f31232805a7

            "sequence" : 0,
            "error" : "NOPx reserved for soft-fork upgrades"
        }
    ]
}

I am going to try this with "-regtest" next (but that might have to wait until tomorrow).

Shit - just realised I was running 0.11.1 not 0.11.2.

After downloading and re-running I now get this:

Code:
{
    "hex" : "0100000001bbc6c76fd91bee5badfb0746204adba70efceb04f21a270de566827dbc34e84100000000842102d1570ab314b7b32ffe76f31232805a7

            "sequence" : 0,
            "error" : "Locktime requirement not satisfied"
        }
    ]
}

I think if I fix up my nLockTime now then we might have a winner.

Unfortunately no such luck:

I am guessing if I can work out the format that is suitable for signing (which will have that 00 and I think requires another 01000000 to be added at the end of the inputs from memory) then I can manually sign it and then try and send the tx.

Anyone can for sure tell me the hex input for signing?

I don't really understand the question. Do you mean you cannot produce a valid signature by using your tool? I checked the rawtx you created and indeed the problem is within the signature. webbtc verifies this as well.

I have written code that signs "standard P2PKH" transactions here: https://github.com/ciyam/ciyam/blob/master/src/crypto_keys.cpp#L805 and if you look closely you'll see c_empty_sig_script (which is "00") being placed where the sig later goes (why I was mucking around with the extra 00 above) and also this:

Code:
signing_info_suffix += c_hash_code_type_all;

which appends "01000000" (only to what is signed rather than what is actually the raw tx).

Basically to manually do a sig I'll need to apply the same approach to non-standard txs (nothing too hard - just some modifications really).

I was actually hoping to just use bitcoin-cli rather than to have to write code though but it's beginning to look like signrawtransaction is not able to do what I am wanting it to.

The error I'm getting when trying to send this raw transaction is as follows:

Code:

Hmm... I wonder if the problem is the CLTV value itself:

Code:
["ac9a09"]

What block number is that (am a bit tired and really starting to hate Satoshi for using little-endian)?

That looks like it is block number 629420.

Looks like 629420 to me too.

So if the block number isn't the issue then is the sig invalid?

(current testnet3 block is 629899 and that raw tx's nLockTime is 629888)

I crafted a tx pair similar to yours (same cltv block and same locktime) in testnet, I think it is correct but it won't be sent to the network.
This is the rawtx
Code:

It could well be that not enough of the testnet peers have upgraded - I think the next step is to play with -regtest rather than -testnet (so you are mining your own blocks).

I wonder if the CLTV is not deployed in testnet yet

It could well be that not enough of the testnet peers have upgraded - I think the next step is to play with -regtest rather than -testnet (so you are mining your own blocks).


That's why I quitted using testnet (and people do not stop asking me why I do the tests in mainnet).
I emailed Josh Cincinnati from blockcypher.com and he said it would be better to run the test in our own testnet, or we can also use their testnet.

Well - I've tried doing this with regtest but unfortunately there seems to be a problem.

Raw tx is as follows:
Code:
010000000194fb5e28b96182167b73934863fdc6cc23502f2574fdca8230b187fcc768171400000000cb4830450221008854a06bb9fd2fc81e9fe01666481e0fc297

                ]
            }
        }
    ]
}

I can even issue a "signrawtransaction" and I get this:
Code:

    "hex" : "010000000194fb5e28b96182167b73934863fdc6cc23502f2574fdca8230b187fcc7681714000000004948304502210089efd7a1beef7bc3eebde1c

000001976a9145e6199a3c0ad658480247a0f30e314aee23db1eb88acff000000",
    "complete" : true
}

which all looks fine - but when I attempt to send it I get this:
Code:
error: {"code":-26,"message":"16: mandatory-script-verify-flag-failed (Non-canonical DER signature)"}

Sad

I cut and pasted your transaction from here into the webbtc page for relaying transactions to testnet3. The page said there was an error because the transaction context was invalid, and rule "prev_out" failed to validate.

I think I basically have the correct raw tx but still Bitcoin won't allow me to send it.

Code:
0100000001bbc6c76fd91bee5badfb0746204adba70efceb04f21a270de566827dbc34e84100000000cc47304402204d5c2b9a9a5a9e467a77d87c0de310c1fa1be7

7dd4d0e29f50f989dd2b97d463d706a7ef0c7b88ac809c0900





This is the transaction relaying page link, and the error message.

Error: Transaction context invalid.

Rule "prev_out" failed to validate:
Prev out 41e834bc7d8266e50d271af204ebfc0ea7db4a204607fbad5bee1bd96fc7c6bb:0 not found.

Although I searched webbtc for 41e834bc7d8266e50d271af204ebfc0ea7db4a204607fbad5bee1bd96fc7c6bb it couldn't find it.
