The first node to broadcast a transaction is probably the one where it was made. You can try to link its IP to a person, but how are you going to do that and what if they used Tor? I guess you're out of luck then
We get a device fingerprint for all transactions that occur on the network, so we can see everything about an from what IP/Proxy they are using, to what version of flash, browser they have. If they are using Tor it makes it a bit more challenging, but at least we can see the IP address that is assigned and look that way
I am not sure that's going to help you. What IP do you log specifically? The local IP is useless (99% NAT, etc.), the Tor exit point IP effectively masks the guy unless you're 3 NSAs. An IP obtained via an external service a la whatismyip is also going to give you the Tor exit node, is it not?
All in all, I feel like your best course of action would be to track fraudsters like you're already doing and try to stop them when they show up again, ban them or something of the sort.
Then again if they know what they're doing, your evercookie, digital fingerprint or what have you will not work properly either.
Just trying to throw out some ideas here, not trying to bash your operation or anything
haha, I agree 100%. In general, the IP address is essentially useless to since everyone is using dynamic IPs, Tor, or something program to prevent us from doing anything with IP. And yes, everything we get would be the Tor Exit node. There really isn't much we can do, but our 'evercookie' does provide some good intelligence if it is the same device performing the same fraud, which we can then shutdown and prevent from doing further transactions.
Still your provider knows what IP was used in what time. So you can find people and IP is sufficient
If you are connecting to a VPN/proxy they cannot tell the difference between the million other connections you have going on unless they did a full blown investigation on every single IP/port/etc you connected to.
Just going to a web page full of ads spits out 10+ IP connections.
If you setup your own proxy system its even more difficult.
You could also setup VMWARE on your pc if you are worry about being identified with other tricks, go to McDonalds use that Wifi.. Go to a hotel.. Go to a nieborhood full of WiFi connections..
So many ways to make you anonymous but Bitcoin by itself isn't anonymous.
I have a theory that one day we will all be assigned an IP (like SSN only on a global scale) similar to how they assign IPs for servers.
Basically if you don't have an IP you cannot get on the internet and everything you do with this IP is forever recorded. No proxy systems will exist and the only way to "proxy" yourself would be using someones IP which then would essentially be like identity theft/borrowing.
This would solve endless problems in the web hosting world, but right now no one will accept it.
