scammers scamming scammers

This forum serves no purpose besides slowly but surely robbing users of their coins.
Do not trust anyone, especially at the higher level.

Useful stuff, thanks! 
Might use it one day

I actually need this functionality for Paysty's multisig part.
I would love it if there was a way to make a raw connection to a bitcoin node and send a tx that way.
Write now we use an Electrum server.
Any chance you could implement the raw connection to a bitcoin node?

Can this tool parse either the binary or the JSON format that Coinbase uses?

I've had more than one occasion where I've been withdrawing BTC that I bought and the transaction takes a long time to hit the network even after their system has created it (as evidenced by the transaction showing up in their system and giving me the option to download it in binary or JSON formats.).

So far I've never found a tool that could read their format and broadcast the transaction manually for me.

What about remote bitcoinds? It might be possible to get a list of bitcoinds via the usual discovery mechanisms, send them the "hello" message, push the transaction(s) over and say goodbye...

That way you could even confirm that it got at least forwarded a bit, once you hear about your transaction from other nodes.

However if Coinbase allows you to download the binary, and that it works on https://blockchain.info/pushtx then yes, it will work. For your usage doing that step should be enough actually.

Blockchain.info won't accept Coinbase's binary format for some reason. That's why I was interested in your tool.

Oh... probably won't work then. Do you have an example Coinbase transaction you could share?

Here's a random one:

https://bitcointalk.org/index.php?topic=343503.0 seems like a perfect match!

[justusranvier]

Ooh, interesting.
It should work with the .bin file - it will pass through binascii.hexlify() as it doesn't match what is expected, and be accepted by the various methods. Now if you try with that transaction, it won't work because it's spent already; but it decodes properly with the one I tested (try with garbage and you get "decode error", try with this one and you get "rejected").

Great.

Next time I encounter this situation where I have the .bin file but the network hasn't seen it yet I'll try it.

Code:

Traceback (most recent call last):
  File "./cli.py", line 4, in <module>
    from pushtx import pushtx
  File "/home/justus/src/pushtx/pushtx.py", line 5, in <module>
    import requests
ImportError: No module named requests

Are there some dependencies that need to be installed for this to work?

[justusranvier]

I'll have to try again next time. By the time I got the dependencies installed, Coinbase finally broadcasted it to the network.
