Did you put the empty line at the end?

Would you mind sharing it with me?

So, Electrum shows this message as invalid. But some other tools show it as valid. This was my answer to OP after he sent me the signed message so I could test it.

Quote
Hey man,

I did some testing here and apparently Electrum is showing the message as invalid. My bet is that this is happening due to the empty line at the bottom of the message (see there is a line between the address and the --- SIGNATURE ---) which it ignores or doesn't verify properly.

However, I tested in another tools and it was verified.

For example:
https://tools.qz.sg/ - shows as valid (with the empty space at the bottom): - REMOVED SCREENSHOT DUE TO OP'S LETTER -
https://reinproject.org/bitcoin-signature-tool/ - shows as valid (also with the empty space at the bottom): - REMOVED SCREENSHOT DUE TO OP'S LETTER -

(both websites were the top links when I googled "bitcoin verify signature message online").

Meanwhile, others I couldn't make it appear valid. (e.g: https://btc.coin.space/messages/verify).

I remember seeing something like this before. Is this because Electrum trims the last empty line (at the end of the message)?

Clearnet site takes a while to load for me, but eventually it does load. Onion site takes less time to load.

I think it has sth. to do with the circumstance that the different world from OS'es and programming languages are not following the same standards as it should be.


Like Windows isnt case sensitive but Unix is,  for example.


@Chipmixer:

May u think about it to avoid line feed or carriage return through an simple symbol like an asterisk (*) in ur receipt then ur on the safe side for all systems.

Windows has CR+LR, Linux just has LR so the cr shows up as ^Z, open a bug report with electrum if you think they didn't just not copy the final return (it's better that way).



@Rahar02 can you delete that link just in case a search engine crawler picks it up and boosts it in the page rank.

Is there any way coinmixer will support Ethereum in near future,
or maybe you know some alternative website that offers ETH coin mixing?

this is only the Electrum Interface what about the others Verify Services in the web

but i agree with u thats not chipmixers fault

despite these may they can improve this with an minor change

You're compromising your privacy if you use those to verify a signed message.

From the ChipmixerFAQ:

If you sweep funds from chip in first 12h after your input, you receive same privacy as you would get from standard mixer. If you trust us (as you already did when you sent coins into mixer) and spend chip when you need it, then you achive maximum privacy you can get.

instead of leave the private key untouched ( not sweeping) to use the Voucher Code before an wait for several days to redeem or are these two things diferrent and not comparable related to increase the grade of privacy.

It's different, but I think the very existence of both options increases your privacy. I'll give an example:
Sweep
1a. You deposit now, and get a private key that was created a day ago.
You wait a week, and sweep the private key. That means any external party can see the funds were moved after 8 days.

1b. You deposit now, and get a private key that was created a week ago.
You wait a day, and sweep the private key. That means any external party can see the funds were moved after 8 days.

To the curious outsider, 1a and 1b look exactly the same! If he wants to find your deposit, it could just as well have been a day ago as it could have been a week ago. Or much longer, as you could have stored a voucher for months!



Voucher
2. You deposit now, and get a voucher. When you redeem the voucher, you continue at for example 1a or 1b, and once you sweep the private key, anyone can only see how long ago the address was funded. They can't know if you deposited days, weeks or months earlier, which makes it very difficult to link your deposit to your withdrawal.

There some approaches like this:

https://bitcoinmix.org/de/eth

https://tornado.cash/


But im not sure if its battle tested for the masses.

so be careful

@LoyceV:

So the voucher step is the game changer to increase the privacy in an significant way in this case  ?
