Hello

last few days some of low size chips were preloaded with Segwit (segwit over p2sh) instead of non-segwit (p2pkh). Out of all withdrawn Segwit chips - none were sweeped by our users. If you were affected - please contact our support - we will help you get your coins.

ChipMixer Segwit rollout will be delayed.

Are they still loaded, can I send a test of a small chip? Or is there an issue with how they were produced?

Maybe people are just holding the funds to allow for a delay?

So looking at this service, and possibly other mixers, aren't they effectively just exchanging my transaction history with another stranger.

For example.

Alice deposits 10 mBTC into chipmixer and gets a 8 mBTC chip and a 2 mBTC chip.  The chips Alice gets were from earlier in the week, so they don't have her TXN history.

Bob comes around later and deposits 10 mBTC and picks up a 8 mBTC chip and 2 mBTC chip.  Bob does something bad with this chips and gets investigated.  When they trace the coins Bob used, they ultimately trace them back to Alice, since Bob happened to pick up Alice's earlier deposit.  So although this is great for Bob, Alice gets a knock on the door with questions about what she's been up to.

[jackg]

No. Inputs of the same type are grouped together by the daemon when they're made.

So part of Bob's transaction might come from Alice's but it's not a key switch it's a key that's given to an address funded by many other addresses.

Alice might end up with 5% of Bob's funds so it means nothing, maybe an Alex did similar and he has 5% in the pool too but he merely wanted to use an exchange without being tracked by the people he was offering a service too (maybe he's freelancing as a job but feels people won't respect him so much if he doesn't hodl his funds).

Mixers exchange money for the same amount of money though. If you want to be more anonymous you have to consider using the donate function or printing off a receipt and just hold onto a fraction of the Bitcoin in the key for a few years if you can...

Correct. And that's why Chipmixer gives you a signed receipt:

Every time you withdraw from ChipMixer, we give you cryptographically signed receipt that proves you have received those funds from us.

For example.

Alice deposits 10 mBTC into chipmixer and gets a 8 mBTC chip and a 2 mBTC chip.  The chips Alice gets were from earlier in the week, so they don't have her TXN history.

Bob comes around later and deposits 10 mBTC and picks up a 8 mBTC chip and 2 mBTC chip.  Bob does something bad with this chips and gets investigated.  When they trace the coins Bob used, they ultimately trace them back to Alice, since Bob happened to pick up Alice's earlier deposit.  So although this is great for Bob, Alice gets a knock on the door with questions about what she's been up to.

A mixer can't change any connection Alice had to a certain address before mixing the coins. If there are any ties between Alice and her 10 mBTC deposit, Alice can be found. This has nothing to do with Bob (who received the chips created out of Alice's deposit), the same thing could have happened to Alice without using a mixer.

But you said Bob "does something bad", that means Bob did this after receiving the mixed coins, and if that's what is being investigated, Bob can't pin it on Alice.

@chipmixer, whenever I try to use your site on my Android phone the captcha gets blocked by the panel at the top. Is there a fix to this. I'm using the most recent version of chrome.

Edit: I can change it to be like a desktop site and that works but can't think of anything better?

Bump!

Have you tried accessing their website via Tor on their onion address? ( http://chipmixerwzxtzbw.onion/ )

I've occasionally had problems accessing their clearnet address as well, but their onion address seems to be unaffected by whatever is causing this occasional issue.

I noticed this error a few times too,
and my quick easy solution is by simply opening the full url link restore session
I think there's a coding error on restoring session through input form

Yes, it does look like to is an error in the code or an error in the file permissions for the code. My way also works.
I don't know what the URL is for a session restore?

Edit: nevermind my way doesn't work, it just remembered the cookie.

I'm getting the same error when I try to manually restore the session. The workaround is to use the restore link as explained above (which is working fine).

Chipmixer...firstly, I enjoy your service and find it to be an interesting and novel mixing service.

I started a mix about 18 hours ago and was given a voucher. Tried redeeming it a few hours later, and got a new voucher. Just tried again, same thing.

I emailed chipmixer@protonmail.com 5 hours ago as well.

Any idea to when chips will be refilled and ready for withdrawal?

This usually occurs when the daemon gets stuck. It's usually fixed within a few days if not sooner.

Thanks...I appreciate the info.

I’ve used CM dozens of times, seamlessly. This is the first time I’ve run into this.
