Title: [ANN] chainsnort (live transaction monitoring and fingerprinting tool)
Post by: flatfly on December 16, 2013, 07:06:09 PM
This command-line tool displays transactions as they are happening on the blockchain.
It's similar to a network trace, but for blockchain activity. It has the ability to automatically flag large transfers.  It can be useful in identifying interesting patterns in transactions.

Warning: watching the live blockchain action can be hypnotic!

Features:
- Print new transactions to the console, in the following format:
   UTC Time, Total Amount (sum of all outputs), Main recipient, Transaction Fee
- Big (50+ BTC) transactions and extreme fees are flagged.
- Also shows "new block" events, with the corresponding block reward
- No private keys, admin privileges, or credentials of any sort are needed.
- 100% Python -> runs fine on OS X, Linux, Windows and Android!
- NEW August 2014: transaction type guessing engine  (in private beta build only)
- Low-latency encrypted websocket connections
- Extremely light on resources and bandwidth
 
I will be adding new features and parameters on a regular basis.


The current data source is the blockchain.info websocket API. Direct local bitcoind support, while a little more complex, could also be implemented in case there is enough demand for that.

Many thanks for your support - donations will help me continue development!

As a little bonus, 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 my 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.

Perhaps you have a different version of Python in cygwin?
ChainWatch uses Python 2.7.

Updated to version 0.384 (see code in OP).

Changes:
- some transactions were occasionally missing - fixed
- cleaner timestamp ordering
- lower network usage
- terminal color output for OS X, Linux and Windows  (this feature is for donators only)

Note: Do not tweak the various timer and buffer values unless you like playing with fire.
You might get your IP address banned from blockchain.info.

Next thing to be added: the fee paid for each transaction is worked out based on the total inputs and outputs and displayed in the right-most column. It gives you a quick insight into what people are paying to get their coins transferred. The color version will flag outliers in red.

Cool

Still no ssl tho

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.


Title: Re: ChainWatch: a lightweight live transaction viewer tool
Post by: flatfly on December 26, 2013, 08:34:32 PM
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.

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.

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

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 :)

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.

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?

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.

This should be the correct library: https://github.com/liris/websocket-client
"Pip install websocket" should grab it, IIRC...

2.7 would work best.

I might put up a gist soon, but it could take a little while, as I have to deal with a serious issue right now, which is taking up a lot of mental energy - I prefer not to go into detail. In the meantime, please watch or subscribe to this thread for updates.

May I suggest sticking the script on github? Using copy and paste is really annoying, especially with python due to the indentation problems.

Version 0.42.2 is ready... (I just changed the version numbers so they make more sense, at least to me...)

Changes:
- Switched to fully encrypted websockets (WSS protocol)
- Minor code cleanup

Source code only for now - Windows build will follow soon.

Nice!

Actually installing chainsnort on OS X is really easy. Just copy and paste into a terminal:

1/ curl -o websocket.py https://raw.github.com/liris/websocket-client/master/websocket.py

2/ curl -o chainsnort.py https://gist.github.com/flatfly/8253870/raw/9733e34e469e1bcd8d0ae13565ade4eaa0490618/gistfile1.py

3/ python chainsnort.py

Version 0.43.3 is out!

Fixes a minor indentation issue with large amounts, and adds output multiplexing (tee-style) support, which allows you to capture traffic both to the console and a log file (just start the tool with the -o argument for that). The log file is called "txtrace.log" and is located in the same path as the script, or in the following path if you are running the Windows executable: %AppData%\Chainsnort\0.43.3\Log.

No documentation or manual at this stage. It will come sooner or later.

Also, I didn't have much time to make progress on direct bitcoind support.
Of course, if anybody wants to help out, they are welcome to do so :)

Next feature (currently under testing): color highlighting of "interesting" addresses, based on a very simple external text file containing a list of addresses to watch for. For instance, in the below screenshot, the 1dice and 1A6TJ addresses are defined as 'interesting'.

OK, I will remove the Windows binary download of chainsnort (complete with color output) very shortly, so get it while you can. Any early users who already own a copy of the chainsnort binary are allowed to freely use it forever. 

Now I don't want to turn it into a typical paid app, but I would like to try a new idea: as i do need thé donations and almost none were received so far, any time a tip comes in through the official donation address <1111127SpvabYpoeDoiz5L7QPkfiSh2Q>, the download is made freely available to anyone (not just the donator) for the next 24h.

The next version will also flag microtransactions (sub $1) in red. Due to the fee structure, only 1% of transactions are microtransactions currently.

I've also adopted the transparent background idea, with RoxxR's help :)

No problems at all just make sure you always test connect before you run your test because the RPC server will not be online 24/7. Also don't hesitate to pm me if you get any problems. Chainsnort with RPC connector will be awesome for sure and I can barley wait:) Anyway keep up the good work and take the time you need.

(getinfo will show the alert info in the error field when a alert is active)

OK, here's a quick development status update on the RPC version:

Open issues:

- some transactions fail to be captured. this is being investigated.
- real-time fee calculation appears to be unfeasible/too slow
  given the current bitcoind API and exposed data structures.
- new block notification is not implemented yet.

-Can this just be to my not so well connected node? I mean blockchain.info got around 1000 connections with nodes all around the world I got 8 connections with one node..
-Can't this be due to latency I bet you got around 80+ ms to my rpc server instead of 1< ms on localhost.

- Yes this is the most likely explanation in my opinion too. Based on my estimates, I believe that with 15 connections, the RPC version should be able to see 99-100% of all transactions in real time. This still needs to be verified in practice (and also depends on how well connected those 15 nodes are.)

- If someone wants to take a stab at implementing fee calculation, all the better! I don't have enough time for that currently.

Thanks. Seems to be back to 8 connections now though. Did it consume too much bandwidth?
The blockchain.info websocket stream was down for much of the day so I couldn't compare results yet.

Later this week, I will clean up the code and post it so other devs can help.

Yes I was forced to cut back to 8. I'm currently on a adsl line with less then 1mbit up stream. So when I play online games with voip I really need all the bandwidth I got. I might be able to start a server on 2,5mbit upload rate at a different location. But until then I will keep changing from 8 to 15 and this week I will need the Internet nearly all the time so it will mostly be limited to 8
Also I know about the blockchain.info thing the api gets blocked by cloude fair. Thats one of the reasons I like rpc support. I also know there are other live transactions monitors like the one Bit Pay just released. But I like the simplicity of this small python script:) It also looks nice in a console window.

I have also implemented a new advanced feature called transaction fingerprinting, which attempts to classify transactions in one (or more) categories based on certain behavioral patterns. Of course this can never be 100% perfect, but I'm aiming for a decent level of accuracy. It is still experimental at this time.

Hi,

- sorry for the delayed responses, I've been literally overwhelmed by the amount of stuff and work lately. Trying to redefine my priorities but it's easier said than done.

- will send the latest private beta build to Dabs as soon as it's ready, later this week most likely

- about donations: they can be sent to either 1SEPsD35L3C6nKUghwNvRHeyGSyTUSRYS or 1111127SpvabYpoeDoiz5L7QPkfiSh2Q and are always warmly accepted

- a new transaction type (XCP_OP) is now detected by the fingerprinting module, bringing the number of different types recognized to 15.  Note: Don't expect to see that new type very easily, there are only a couple of XCP transactions done per hour.

And thanks for all the feedback!

Chainsnort now recognizes P2SH (multisig) transactions and tags them in real-time!

Screenshot upcoming...

It's awesome to check on my node, but it's missing live transactions

A little screenshot of the latest windows build, highlighting a large multisig transaction:

http://i.imgur.com/jYaUtqa.png



Also, starting today I will be experimenting a new funding model and see if it's sustainable:
  
  • on odd-numbered weeks, the latest stable Windows build for chainsnort can be obtained at no cost - just PM me for the download link
     
  • on even-numbered weeks, the download will cost 0.255 BTC - send the transaction and PM me for the download link


Hopefully the revenue will help cover part of my development time.

I have a business idea for you. Traders would pay to see large transactions entering and leaving exchanges.

Exchanges don't publish lists of addresses they hold, this would make them easily auditable.

Very useful code!

One question though. I wrote my own version which basically just takes in any unconfirmed transaction and write it to a file. And I also tried the json API provided by blockchain.info.
***
https://blockchain.info/unconfirmed-transactions?format=json
***
What surprises me is that websocket missed several transactions. Is there any way to make sure that the websocket API will return ALL unconfirmed transactions?

I doubt it, it's not meant to be a reliable api, you'll have to roll your own node possibly with that bitpay software

You can verify whether the address belong to exchange or no by dint of big transactions with huge number of inputs. No software required.

Blockchain.info uses a special system that doesn't involve Python (as far as we know), they're most likely using a modified node that notifies them of transactions.

The easy way

Just use Blockchain.info's transaction notification service. Their web sockets api lets anyone subscribe to any bitcoin address
The hard way

If you want to listen to all latest transactions, and not to addresses you own, you're going to need more in depth control. Otherwise use Bitcoind and its wallet notify parameter. Check out PyNode, a Bitcoin node implementation in Python.

Sorry, that websocket link is broken. curl -o didn't work either anymore for me. Try:
Code:
git clone https://github.com/liris/websocket-client.git

cd websocket-client

python setup.py install

wget https://gist.github.com/flatfly/8253870/raw/9733e34e469e1bcd8d0ae13565ade4eaa0490618/gistfile1.py

I thought I did, but turns out I didn't  :-\ . All I can find for gistfile1.py (posted Jul 6, 2015): https://www.snip2code.com/Snippet/576729/chainsnort-0-484--latest_stable-

I gave it a quick go and after creating an empty file called prefixes.txt, it seems to work ok.

flatfly was last active on August 01, 2015, so until he comes back I put it on github as a backup. You can get it using:

Hello,

I've been playing around recently with adding this functionality to my bitcoind front-end.

Those of you who aren't running full nodes will not find this useful. However, if you do have a full node, you can do all of this locally without external API requests. It may even be faster (I have not tested chainsnort, so I do not know.)

https://github.com/esotericnonsense/bitcoind-ticker

At the moment this is just a proof of concept and does the absolute bare minimum required. No highlighting or anything fancy, just spews out transactions to the terminal. The idea is there though.

Define update - do you mean adding new features, or updated binaries?
