We are back online. Another mixers owner has sent over 7M requests to our .onion address (and it is not over yet). We have updated our code to mitigate this attack. Now every new session requires solving a captcha (sorry about that), but at least you can access ChipMixer now.
That explains why the service yesterday wasn't available for quite a long time. I have noticed that it is happening quite regularly that the service experiences a time out, while I must say that these by far aren't as severe as the time out from yesterday. It's a sign that ChipMixer is gaining popularity, which is what certain competitors can't accept. Is that same mixing service also responsible for previous time outs, or are these largely the result of more usage/demand?
I have a concern people, Let's say I send 1 BTC to Chipmixer and it commonizes into smaller chips, example 0.25, 0.1,0.1,0.5 etc etc.. and it gives me the keys all good. But when you spend the transaction and spend it anywhere it seems like it's very easy to pinpoint chip mixer transactions in a block.
Lets pick any block for example and see that there will be barely any transaction that's output is EXACTLY in 0.25 or 0.1 or 0.125 and if there are any transaction you can easily link them to chip-mixer transactions. I been scrolling through last few blocks and I can't seem to find any exact whole output.. when I did a transaction it was so easy to notice on block explorer in the block that was mined.
I suppose the only privacy we get is the fact that no one can pinpoint who exactly sent how much to chip mixer.
