What happens if we do not associate any account with our bitcoin address?
When I transfer funds from the bitcoin exchange sites to my bank account, my identity is revealed.
But what happens if I make all my purchases online without making a connection with my personal account?

In short, I wonder if the bitcoin protocol itself is anonymous? Is our IP address logged?

The most practical method to stay completely anonymous is to use a mixer service which you could set receiving addresses and even set delay time in sending orders, and no matter from where you are sending your bitcoins to the mixer's address, your IP is no longer an issue.
IP addresses of the nodes are logged anyone relaying transactions but they might using TOR so you can't really tell if it's their real IP.

Mixing bitcoin is like using burner phones.

Do not we see the first address and last address in the bitcoin laundry sites?

For example, x my personal address. the mixer sites are addresses a, b, c, d, e, f
I transferred money from address x to address c. The mixer site transferred the money between his addresses.
Example process: x -> c -> f -> a -> e -> b -> d

Now, when I want to use the money at d, can not it be found that this money comes from x address?
Can not they ask where you got this money from?

the path of money is more like:
X is a matrix of 1000's of addresses
each one of them moving, like you said: -> c -> f -> a -> e -> b -> d
and finaly from d to 1000's of destination addresses.

so, do you think you can trace back the path of all this transaction's?
believe me, it will be really really hard mission.

Could you explain a little more? Is it a 1000X1000 matrix? And do you have randomly generated btc addresses in the elements of this matrix?

And how do you process these matrices? multiplication, addition?

I didn't mean actually a matrix of x by y addresses, just tried to demonstrate there are a lot of addresses uses the same paths so it'll be very hard to trace back a single transaction.
And I guess they add some dummy transactions just to make it harder.
Anyway, if you know someone who can figure out the origin of a specific transaction let me know

We can think of a solution by knowing what mathematical rule the mixing process is based on.
There are advanced math programs. For example MatLab
Do you know the algorithms used by the mixer sites?

I'm actually pretty good with MATLAB scripts, working on it on my work.
Maybe I'll try to code something to figure it out, but I'll need some references. I'll do some transactions myself and then use this knowledge to trace it back. Then I'll try to trace others' transactions.

Before you do this, you need to know the algorithms that mixers use.
As far as I know, no mixer sites not share source code.

But if I don't know the algorithm I still can try to figure it out by examples.
If I use their service I can track my own money, and I can learn from that how they work.
Of course they can change something once in couple of days and then my work is useless.
