Topic: Is this 16-of-16 multisig tx redeemable under current bitcoin implementation? - page 2. (Read 3279 times)

Thanks! Unfortunately this means the signature will be invalid because the same endianness problem exists in my TX serialization code (for the prev tx scriptPubKey).

I'll go back fuddling my script a bit and try again (if nobody else claims it).

You have "fd 04 a1", while it should be LSB: "fd a1 04"

try this:

So here's my solution to the 16-of-16 multisig... I know it is non-standard but the signature check should pass... but I'm simply getting "TX decode error" even from the Lightfood Hosting's node.

Anyone can tell what's wrong with this?

WTH this is obviously way above the max scriptSig size... not even eligius accepts it 

here is 20-of-20 solved (not by me unfortunately)

Thank you very much!!! I've been able to relay non-standard raw tx to eligius.

Just got this 2-in-16 multisig solved:

https://en.bitcoin.it/wiki/Free_transaction_relay_policy

well isn't it effectively unredeemable if no nodes will relay your tx?

of course if I control a pool or own some significant hashrate maybe that isn't such a problem.

except that non-standard does not mean unredeemable

Thanks! Yes each signature requires 0x49 (105) bytes of scriptSig. 16 copies would exceed the limit.

On the other hand the 16 signatures are identical. But OP_DUP is disallowed in scriptSig.

So it looks like that tx is unredeemable.

Are you going over the size limits?

Error messages from those services tend to suck badly.

Speaking from experience, I will say that writing a varint handler for a parser is easy, and I'd be amazed if more than one of those sites got it wrong.  More likely, they are passing it to bitcoind, which is rejecting it based on the IsStandard() check, and they simply report all errors as "parsing error"s.

But please post the raw transaction here so that we can check it.

can you post the raw transaction here?

I'm referring to this tx: https://blockchain.info/tx/2ee6d8ea223e118075882edba876f01b30f407eb6c6d31c40bd6664a17f20f0c

The problem I see is that the scriptSig necessary to redeem it must contain 16 identical copies of signatures. The result will be over 1KB and thus the scriptSig length field (a varint) will be using the 3-byte long format ("fd 04 90").

I tried to push such a tx to a few places such as blockchain.info, coinb.in, and webbtc.com/relay_tx, but all of the report "parsing error".

I'm pretty sure the parsing error is caused by the 3-byte varint format for scriptSig length (for example if I only include 3 copies of signatures then the scriptSig will be shorter than 0xfd bytes and thus using the 1-byte short varint format, then I'll get "invalid signature" error instead of a parsing error).
