Does this officially unofficially make suchmoon an imposter?

MehMeh painted a new Bitcoin-logo artwork recently, but it's not finished yet. It could actually serve as a logo. A logo created by someone much younger than Bitcoin Cheesy

8206  Bitcoin / Bitcoin Technical Support / Re: A newbie seeking a helping hand on: April 07, 2022, 07:09:12 PM
If you imported only an address into blockchain.com's wallet, it can't export the private key.
If you have the private key, you can import it into Electrum directly when you create a new wallet and choose "Import Bitcoin addresses or private keys".
8207  Economy / Services / Re: [OPEN 11 left] [banned mixer] Premium Review and Suggestion Campaign on: April 07, 2022, 02:40:20 PM
Using a third-party website to verify a signed message is terrible for privacy, but the site might work offline. I haven't been able to test that, because I haven't been able to verify the LoG. All I get is:
Quote
Signature Verification Failed
I'll continue my review here. The delay is caused by me (Support Chat answered after 2 hours, I took 3 days to continue my testing):
Me:
Quote
Can you walk me through verifying the LoG on 8gwifi.org, or any external tool? I still can not figure it out.
Support Chat:
Quote
Of course! So first, visit the site https://8gwifi.org/rsasignverifyfunctions.jsp. After that, select Verify Signature option first.
Public Key: Enter the public key in the LoG including -----BEGIN PUBLIC KEY----- and -----END PUBLIC KEY-----
ClearText Message: Enter the content of SIGNATURE FORMAT in the letter of guarantee, but without memberCode and so on. Only the content that comes one line after with your real member code and so on.
Provide Signature Value: Enter the content of the signature in the Letter of Guarantee. Here without -----BEGIN SIGNATURE----- and -----END SIGNATURE-----
You will also need to choose SHA256withRSA in the RSA Signature Algorithms below
Then it will show that the signature verification is passed
This verified the signed message. It might be good to add verification instructions to the website.
But 8gwifi.org's verification didn't work offline, so chances are the 8gwifi.org server now knows the details of my transaction.
After I verified the LoG, I made a deposit. I used a short delay to speed things up.

When I checked my wallet after a while, it had 11 confirmations already. But the site (on Tor browser) still shows an animation and this:
Quote
Awaiting Confirmations
0.00xxxxxx BTC 0 / 2 Confirmations
If this can be fixed to auto-update, that would be great. I thought fees must have gone up, so I was still waiting until I checked my own wallet.
Reloading the page fixed it.

After reaching Step 5 ("Done!"), I can't check back the earlier steps anymore for the exact details, but at Step 4 it showed that I would receive a slightly larger amount than what I actually received. The difference wasn't much (maybe 1000 sats), but this should have been the exact amount. The total fee is now about 50% higher than what it showed earlier.

Suggestion: can you make the random fee provably fair? For instance, you can use the order ID and block hash of the incoming transaction as input to generate the random number. This might prevent complaints if someone is charged 3% on a large deposit. This can be prevented if both you and the user can't know fee before the deposit gets confirmed.

Coinjoin?
Now the thing it's all about: a coinjoin transaction! The transaction I received had 1 input and 2 outputs.
Let me quote from /en/why-unijoin]the website:
Quote
CoinJoin is a method where different people join together a single pool and together create a single transaction where each of them give coins as inputs and fresh & anonymous addresses as outputs.
This didn't happen. I expected my own deposit to join a pool of other transactions, and be included in the transaction that funds my withdrawal address.

I followed my withdrawal up the blockchain, until I got to March 29, 2022. This is the first transaction that looks like a coinjoin. But if I follow it a bit further, I get to many parent transactions that look the same, which makes me think the same funds are being used for several coinjoins in a row. This one is from February 10, 2022 for instance.

The entire concept of "UniCode" doesn't make sense when doing a real coinjoin:
Quote
With this UniCode we make sure that the same coins are not sent again to the same user in future mixing operations.
With coinjoin, I expect to receive part of my own coins back. What you're doing now is what most "classic" mixers do.

From /en/terms-and-conditions]Terms and Conditions:
Quote
The service is provided on a non-custodial basis.
~
trustless CoinJoin
I'll get back to this later.
To conclude: it's not non-custodial, it's not trustless, and it's not coinjoin. I've said this before in a discussion with another mixer: you're in the business of trust. People need to be able to absolutely trust you're going to do what you say you're going to do. Now it looks like you're using buzzwords to inspire confidence. All in all this does the opposite: if you lie about things that I know for sure are incorrect, how can I trust you on other promises, such as not keeping any logs?



One more thing: Support Chat rejects many normal characters, I can't say "can't" and I can't use (brackets). If that can be fixed, that would be great! It's annoying having to remove common characters for every message I post.

This completes my review. Sorry for doing it in several parts, but it was necessary to verify things before I could continue with confidence.

If I am not wrong you have an archive of feedback page, no?
I have incomplete old data (scroll down to "trust").
8210  Other / Meta / Re: [POLL] DT Trust/Feedback Activity Log on: April 07, 2022, 07:07:29 AM
My goal is to produce a weekly list of all the trust-feedback that DT members send and receive within the previous week.
How do you handle added or removed DT-members?

Quote
I have removed the users that do not have any feedback activity for simplicity sake.
How about highlighting the DT-members without any sent feedback? Those users should probably not have been added to DT in the first place.

Quote
Trust summary for willi9974 - 216582

Received Trusted Feedback -
1.) Feedback Type: Positive | UserID: 1545702 | Username: DeepMining76 | Message: Alles PERFEKT gelaufen.
You asked for suggestions, so here it goes: use less words and more colors and links. So add a profile link to the username, don't show the userID. Don't mention "Positive" but make it Bold. Make negative feedback bold red, just like the forum does. Add the Reference link and feedback date.
Now it looks like a long list that I'm not going to read. To make this useful, it should quickly provide relevant information.

If you want to go wild, you could make this for DT3-members too. I've never really looked into those, but it might be useful to find members who deserve to be on DT2.

Why make it weekly, and not daily? Much of the feedback drama doesn't even last a week. Since it's only about 1000 pages to download, doing it daily shouldn't be a problem (I scrape much more than that).

I'm missing the most interesting thing: deleted feedback! Those are much harder to find without remembering every feedback ever received. If you can automate that, it can become a valuable resource for keeping track of who did what when.

I recommend you to do this on your own website just like what LoyceV, TryNinja, BPIP team do with their third-party websites with some data, updates.
Yeah, be careful there. It starts with small external storage because of the limited post size, and then quickly gets out of hand into storing 17 million files Cheesy
8211  Bitcoin / Bitcoin Technical Support / Re: A newbie seeking a helping hand on: April 07, 2022, 06:05:41 AM
If you imported the address and you didn't import the private key, now you have a watch-only address and that's why you can't make any transaction.
@Redmalak: this is often used to scam people. It works like this: someone else creates a wallet at blockchain.com for you, or someone tells you to import an address before you received funds from them.
If that's the case, you most likely got scammed. If you created the address yourself (for instance on a paper wallet), you can use the private key to access the funds. Be careful when handling private keys, don't just do things before you understand what you're doing (and don't share private keys with anyone).

I've been wondering about the forum software / database size, though.
It's probably not that much. My inefficient collection of all kinds of data on loyce.club fills 250 GB now, with 17 million files. 211 GB of that is online. My posts archive fills 142 GB, and I know it would take up less disk space if I would use a database instead of millions of files.

Quote
Does the forum just have so many BTC in reserve that it doesn't matter?
With 1250BTC, I don't think a couple hundred GB server storage matters much. The Bitcoin blockchain is bigger.
8214  Other / Meta / Re: How I can get high rank in BitcoinTalk ? on: April 06, 2022, 03:58:50 PM
But it turned out that the wise LoyceV does not consider this a huge violation, that is, you can easily create a second account for yourself, and not worry about earning merits for the second account, but simply transfer your merits from the first account to the second.
~
feel free to distribute your merits to your alts
That's not a good summary of what I said. I'll quite a small part for context:
It's certainly not done to Merit your own alt, and shows not the best morals, but I also don't think it's worth ruining an account of an otherwise okay user.
~
You stopped Meriting your alt the moment you realized it's frowned upon. Even though you had more opportunities, you didn't self-Merit again.

Based on this, I don't think this deserves negative feedback. I think neutral would fit better. I'll make a Neutral tag myself.
8215  Other / Archival / Re: [ANN] Buy virtual Mastercard Debit Cards with crypto without KYC. on: April 06, 2022, 12:51:22 PM
Regarding company details, we keep that private related to OPSEC.
Great! I value privacy, especially when it comes to crypto. But if you say Debit cards are issued by Cripto Debit's bank partners, I find it hard to believe banks do business with anonymous entities. And if you're not completely anonymous: why hide yourself from potential customers?

If there are admin that want to try our cards please send us an email.
I think it's very unlikely Bitcointalk Admin is going to test your card. Some users may want to do it. I'd offer to test it by myself, but I have no use for a creditcard.

We see that a lot of users fund their accounts with high amounts and let it sit there idle.

A new policy update: After 6 months of no card purchase, we will take a monthly maintenance fee of 1% of the balance.
Your website is less than a month old. Why rush users to spend funds?



I see potential, but I also see several red flags.

8217  Other / Meta / Re: Spam triggered by a keyword? on: April 06, 2022, 09:39:39 AM
Either some shitposter decided to farm new accounts, or there's a service to leave positive feedback about services triggered by keywords.
This has been going on for years, in many topics. They spam something that may be slightly on-topic, often with an irrelevant story. My guess it they're a combination of sweatshop workers and bots. And some topics are just filled with spam.

8220  Bitcoin / Development & Technical Discussion / Re: Prefix Difficulty Calculator c# assistance please! Base code included in post. on: April 06, 2022, 08:01:49 AM
most searchers user a /2 formula for case insensitive
 for example
1oojoo1 =888446610539
but
-c 1oojoo1 =444223305269
but in this case only 1/6 can be decreased
leaving 16.6666666667% of the prefix able to be divided by 2
(8.3333333333) therefore a reduction of 8.3333333333% of the initial 888446610539 difficulty
this means the adjusted difficulty is truly 74037217544 (I think Huh) with a case insensitive option applied.
Your math is wrong. I use vanitygen instead of VanitySearch, and as far as I know it shows correct difficulties.
I'll explain with a very short test so the difference in difficulty is easy to see:
Code:
./vanitygen 1t
Difficulty: 1353
./vanitygen 1T
Difficulty: 1353
./vanitygen -i 1t
Difficulty: 676
This makes sense, right? Searching case insensitive doubles the chance of finding a match, so the difficulty drops 50%.
Adding a "o" (which doesn't change when you search case insensitive) means the change in difficulty is still 50%:
Code:
./vanitygen 1to
Difficulty: 78508
./vanitygen 1To
Difficulty: 78508
./vanitygen -i 1to
Difficulty: 39254
If, however, you would search for "tt", the difficulty drops by 75% because you're now searching for 4 different prefixes:
Code:
./vanitygen 1tt   
Difficulty: 78508
./vanitygen -i 1tt
Difficulty: 19627
./vanitygen 1tt 1TT 1tT 1Tt
Next match difficulty: 19627 (4 prefixes)

PawGo's list shows the exceptions: prefixes starting with certain characters are less likely to occur.
