[ANN] chainsnort (live transaction monitoring and fingerprinting tool)

[robanswe]

I'd like to thank robanswe, who kindly gave me access to a full node for developing the RPC connector.

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.

I just can't stop admiring developers on this forum - what you guys are doing is amazing!

Ok, moving on to harass other coders... They deserved it

Here's a very early preview of the 100% RPC version... Only transaction hashes are displayed in this proof of concept, but the live capture method is already working out nicely:

It's nice to see that you are making progress:)

Indeed it's been progressing nicely:



A few kinks remain, though, and will take longer to iron out.

Wow looks a lot better then I had hoped for! Anyway I had an idea now when the program can connect to the bitcoin-qt client wouldn't it be cool to have it write out network alert messages with bright red text or something? https://en.bitcoin.it/wiki/Alerts Maybe even add some alert piping sound.


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

Sounds like a good idea - I'll look into implementing this and put it on my to-do list!

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.

It's great to see some progress being made:)

-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.

I changed to 16 connections. Anyway if you could upload the latest source code to github or something someone might be willing to help. I think my coding skills is a little to bad but I will take a look for sure.

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've posted the current RPC skeleton code there:
 https://gist.github.com/flatfly/9151814

I didn't have time to further work on this in the last few days, unfortunately.
If people are interested in Windows builds, do let me know.
(And donations do help get things done! )

Got it working after some trial and error. Anyway it seems to work fine and I will see if I can improve it. A Windows build would be nice but a colored version for Linux would be even better.

Demonstrating the highlight-arbitrary-address feature:



At this time, this is only available to donators and private beta testers.

Note: in case you're wondering, the "1Dorian" address is part of a fundraising campaign started today by Andreas M. Antonopoulos for Dorian Nakamoto.  Read more about it here:

I'm getting the below error message when starting up chainsnort. Any help?

Looks like blockchain was down

moment I still need time to fully understand this because every read and understand that I am here several times makes me confused whether it was easy to make a profit?

 

This is not for profiting, just fun

please reup the windows version !!!!!!!!!!!!!
