The best

Thanks, glad you like it.
I guess I need to take some rest now...

Ok good night

[flatfly]

Added fee column.
Cleaned up output style.

After some more testing, I have now enabled SSL in version 0.387 (I just added the extra 's' actually.)
It works just fine as long as you have a version of Python compiled against OpenSSL - which is usually the case.

[flatfly]

Version 0.4 is now out.

It is almost a complete rewrite, due to the discovery of a serious bug in the blockchain.info JSON API.
The best alternative was to switch to the websocket API, which offers better performance and reliability for this type of usage.

The code is simpler and more efficient, but the websocket library is now a requirement. (sudo pip install websocket)

To make this less of a pain to Windows users, I plan to provide signed precompiled binaries soon.

[bitpop]

Cant wait for windows but then again, security risk

[flatfly]

Here it is...
And for a limited amount of time, it is the color version that is freely available.

Of course standard security precautions apply, as always with Windows software.
(More detailed warning to be added)

Just sent you a few bucks as a donation. All I can afford these days.

Cool little utility. And when I see amounts like 300+ being traded makes me cringe! Big time money going through.

[flatfly]

Thanks for the donation!
OK, I have decided to rename the tool to "chainsnort". My geeky friends like the new name better!

[flatfly]

OK, version 0.410 is out, which also detects "new block" events, and has a bugfix in the windows build.

Also, you will be treated to a colorful ASCII easter egg (in the windows build only, for now), if chainsnort sees a tip being sent to this special tip jar: 1111127SpvabYpoeDoiz5L7QPkfiSh2Q  
The easter egg changes depending on the size of the transaction

I also have a separate edition with some features that are useful for forensic and technical investigation purposes. I'm not releasing it at the moment but PM me if interested.

Please move away from trusting blockchain.info and run this against bitcoind RPC... the added benefit would be that it could be easier to do this for altcoins too.

[Gonzo418]

Very cool stuff. Also thanks for the code !

Support for bitcoind RPC is already on my to-do list.

My bad, copy paste issues! (It was a non-final version that was mistakenly posted)
I've fixed the code in the OP, can you try again and let me know if that helps?

If it doesn't, please post your OS and Python version.

[arnuschky]

Which version of websocket do you use? Somehow my install says

Code:

AttributeError: 'module' object has no attribute 'create_connection'

Installed using pip

[flatfly]

Great work, great functionality from a small amount of code. Thank you!

(I'd also like to see Bitcoin RPC usage, it's a little more complex on the user's end but it's more malleable! https://en.bitcoin.it/wiki/API_reference_(JSON-RPC))

Thanks, always love this kind of feedback!
This started out as a quick hack to teach myself the joys of JSON, so I'm really glad to see that people like the result.

As for bitcoin RPC support, I'd really want to add that as soon as possible, but I will have less
free time as of tomorrow, so it might take a while, so if someone wants to have a go at it...
Which reminds me, I should probably set up a proper github repo.
