61  Bitcoin / Project Development / Re: Bento Wallet - easy-to-use, lightweight, inspired by Uniswap on: December 31, 2020, 02:45:03 PM
My question: did you ever give any crypto to anyone as a gift? What method did you use? Did the person you gave it to had any problems with understanding it?
You can just give them a private key which they can import (If they trust you), or explain to them how to set up something like Electrum..

I would never keep anything on this online wallet you call bento.
Website is badly made without any information about it, and when I tried to register it gave me some error with bad spelling:
''An error occured while processing your request. Please check your information and try again.''
Yeah, I neither was able to register. By registering using an email, I assume this wallet is somehow custodial?

Quote
With Bento, you have one click account setup and funds transfer. Should be easy enough to understand for someone who doesn't know anything about cryptocurrencies.
So how would it differ from something like blockchain.com's web-wallet? (I assume it's roughly the same?!)
62  Economy / Service Discussion / Re: codecanyon.net subscription on: December 30, 2020, 10:20:25 PM
I need a little help. Does anyone have monthly or yearly subscription of codecanyon.net? I need some template/scripts to download, if you can help then please PM me.

Cheers,

Do you want legal or illegal options for download?
I may not be allowed to share links here but try to search for "group buy SEO tools" + codecanyon. I think you will find organized buying licenses and as I know there were offers for a shared monthly license for codecanyon, just for a few bucks.

What will be the illegal option to download something from codecanyon? Need to know to have a knowledge about the way.
Don't really think this is a good idea... I'm not sure what sort of script you're looking for, but there are dozens of open-source templates out there.

And if you really want a custom one, might as well pay 30$.

If you try to download it illegally somewhere, it's highly likely the code is either tampered with (eg. backdoor), or that the download itself contains shit like viruses.

Really though, if your website is worth more than 50$, I would never use a nulled or cracked version of some script.
63  Other / Beginners & Help / Re: A couple of questions about privacy on: December 29, 2020, 10:03:16 PM
I have been reading about transactions, privacy, coin control etc. The truth is that until now I haven't worried much, but a couple of doubts have arisen.

The first one: if you don't have much bitcoin and you haven't done many transactions, you should be very worried about it?

The second one: would it be a good idea for example that what I earn with the signature campaigns goes to the same address and I use that address to send bitcoin without mixing with other of my addresses?

In other cases I think it will be unavoidable to use different addresses for sending bitcoin if you have little money in the addresses and want to send more.
You're totally incomprehensible.

What exactly are you worrying about? Whether or not you are identifiable if you make transactions from the address you received your sig campaign BTC on?

Well, yes. anyone can track that given they know your deposit address.

But this sounds more like a topic for Beginners & Help.

Quote
The first one: if you don't have much bitcoin and you haven't done many transactions, you should be very worried about it?
You should be. Once a link is made, it can never be undone. Let's say you make a transaction now that could identify you, for example from your address linked somewhere on the forum to an exchange such as Coinbase, and it'll forever annoy you, as it could potentially identify you in the future, when your standard for privacy, or care for it might be higher, if that makes sense.

Quote
The second one: would it be a good idea for example that what I earn with the signature campaigns goes to the same address and I use that address to send bitcoin without mixing with other of my addresses?
That's a good privacy precaution, that is, if I'm understanding you correctly, but it practically does nothing to hide the source of your funds.

It's me bowsemodso from bitcointalk 28/12/2020
</message>

bc1qsg75a4ucmtupx6q75265y5g7pu5jahqmu05z27

IAyykr8rB64IWYJZ4DlXtp8PSLXFJkhtqyhj5UoJNKLEBTGLeEt3c0+MsYCyCiY+OQ4l9833NsMowDEtv5kpn0E=

Verified.

So I've gone back and forth with this user, and can conclude only the following.

1/ bowsemodso owns bc1qsg75a4ucmtupx6q75265y5g7pu5jahqmu05z27 and has sent 15 BTC to 3QxbSAUex9vXRvf3RKc1j2MdyjqTpofY6B

2/ bowsemodso has actually sent a lot more BTC to two addresses, which he claims belong to MyCryptoMixer.

3/ bowsemodso has done multiple previous transactions with MyCryptoMixer for extremely large amounts for which he DOES have the LoG, and they check out. I can confirm he both sent the transactions, and that Mycrypto mixed them.



So, what's left? Well -- there is no direct proof that MyCryptoMixer scammed bowsemod by replacing his deposit addresses, because we do not have a LoG.

However, this story is just.... funny. Obviously there are a plethora of other reasons as to why his coins disappeared into the void, so really, I'm not sure what to make of this.
65  Economy / Scam Accusations / Re: mycryptomixer.com scam or bug? on: December 28, 2020, 06:07:46 PM
Sure.

First wallet what appear was:
3QxbSAUex9vXRvf3RKc1j2MdyjqTpofY6B

After i made transaction in 10 minutes new wallet was:
34Py4cB4yRor1SLRuxsUpmvKZ87DuNzJRE



Oh no, I mean the contents of the LoG.

which looks like
Code:
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

{
<data>
}
-----BEGIN PGP SIGNATURE-----

<sig>
-----END PGP SIGNATURE-----

BTW: that's a hefty sum of money. I'd proceed with caution if I were you, and make sure you don't reveal any personally identifying information.
66  Economy / Scam Accusations / Re: mycryptomixer.com scam or bug? on: December 28, 2020, 05:58:41 PM
Can't you just post your LoG publicly?

If not, I'd be interested in verifying it for you.

So i get better coins ?
If i do kyc ?  The stable coins like usdt and all ready coins with value ? So i can exchange them instant to fiat if i want ?
No, they're just artificially pegged to USD/EUR.

KYC is not at all related to being able to buy these coins. I'm pretty sure you can get them on Binance just fine.

Quote

That might be possible on binance, but it's not an intrinsic property of this coin, obviously.

BTW I'm not sure how it is nowadays, but previously there was no proof at all that these stablecoins were actually 1:1 backed, so just keep that in mind when using them for long-term storage.
68  Other / Archival / Re: Confirmed transaction on: December 27, 2020, 04:23:59 PM
Dear all master..
I have done bitcoin transactions on 22 December, then on 26 December the transaction has been successfully confirmed, but until now the Bitcoin coins have not entered my wallet .. What do you think is the cause of coins not entering the wallet?  Please give me an explanation because I am new to the world of crypto

Could be several causes, depending on the wallet you're using. Are you using a web wallet? If so, are you sure it's legit? eg. have you verified the download before installing the wallet?

If you're using bitcoin core / electrum, again, are you sure it's legit / you didn't get clip-board hijacked (sent to the wrong address), and if not, are you actually connected?

On electrum for example, there should be a green/blue dot in the left? corner.



So really, to determine what the issue is, we would need a lot more information, starting with

1. what wallet are you using?

I'm not that familiar with telegram, but why would you want to do this in the first place? I know I wouldn't click any link DM'd to me by a random weirdo.

If it's your own group, can't you just make a bot instead of a user account, or are these the same? https://core.telegram.org/bots/faq

hi im looking to get a quote for tor a page.

It's not that hard.

Just google how to set up a hidden service with apache/nginx there are literally step by step tutorials, and if you want to generate a vanity address, you can just use something like mkp224o for v3 addresses.

Just google it and there's tutorials on that as well.
72  Bitcoin / Development & Technical Discussion / Re: The Lightning Network FAQ on: December 25, 2020, 09:42:31 PM
I know I asked something similar before and never got an answer, is there any software out there that monitors your Lightning Node and lets you know if it's unreachable?

I now have the server itself monitored along with the bitcoind / lnd / etc. But I would like to know if there is a way to know that for some reason it can't be seen by the outside world. Happened the other day, server was up and running fine along with all the services, BUT for some reason it could not see the outside world, or at least the outside world could not see it. A quick reboot fixed it, but a little warning would have been nice. Honestly if I had not tried to send a payment I never would have know that nothing could route to it.

-Dave

Can't you just ping or telnet from a different machine?

Code:
telnet <ip> <port> 

Should connect.

so BFX's node would be 
Code:
telnet 34.65.85.39 9745
which seems to work.

if you want to see if your lighnting functionality actually works, you'll probably need to set up a second node and try a HTLC every so many minutes...?

74  Bitcoin / Development & Technical Discussion / Re: BIP39 Calculate checksum on: December 17, 2020, 12:17:00 PM
What I'm understanding, is that the 12th word can't be predicted from the 11 first words. I need to choose a random 12th words, cumpute something, getting the checksum and chose the words that validate my seed ?
If you have 11 words, for finding a valid 12th word, you have to brute-force it. Because for 12th word, you need the checksum and for computing the checksum, you need the first 7 bits of the 12th word as well.

He has complete access to his entropy. I think he's just confusing the terminology here.


Convert it to a buffer or something, calculate the length (16), multiply by 8, we get 128.


Can you detail this step please? Thank you for your time.


P.S : So I need to start from a complete 128bits seed (12words) , and not 121bits (11 words). So I need to bruteforce last 7bits to calculate 4bits checksum...
Yes, you need to hash your entire entropy. (which is not 12 words, it's just 128 bits.)

Code:
So I need to bruteforce last 7bits to calculate 4bits checksum...
Why?
75  Bitcoin / Development & Technical Discussion / Re: BIP39 Calculate checksum on: December 16, 2020, 11:54:54 PM

You already have 11 words: possible wage deliver gossip first party hair antique salute fuel survey miracle, the 12th word is a combination of 1000110 and a 4 bit checksum. So the last word 10001101011 "miracle" is actually invalid.

Your first 128 bits are 10101000100  11110110001   00111010000  01100100111  01010111011  10100000100  01101000010  00001001111  10111110110  01011101111  11011010101  1000110. This is the 128-bit entropy. It is 0xa89ec4e8327577411a104fbecbbf6ac6 in hex.

Your checksum is first_4_bits(SHA256(entropy)), or for your example:

SHA256(0xa89ec4e8327577411a104fbecbbf6ac6) = 0xfdd211682c17f1af399453a541827c07

We take the first 4 bits of this hex, which is 7 ==> 0111. Then we append this to the entropy to get:

 10101000100  11110110001   00111010000  01100100111  01010111011  10100000100  01101000010  00001001111  10111110110  01011101111  11011010101  10001100111

I think i'm confused now. How did you end up with 0111?
76  Bitcoin / Development & Technical Discussion / Re: BIP39 how software found the checksum? on: December 16, 2020, 11:29:04 PM
Yes, it's entirely possible.

Take your entropy.

1010100010011110110001001110100000110010011101010111011101000001000110100001000 0010011111011111011001011101111110110101011000110

Convert it to a buffer or something, calculate the length (16), multiply by 8, we get 128.

divide by 32, we get 4.

hash 1010100010011110110001001110100000110010011101010111011101000001000110100001000 0010011111011111011001011101111110110101011000110

first to buffer
168, 158, 196, 232, 50, 117, 119, 65, 26, 16, 79, 190, 203, 191, 106, 198

hash -> 191, 75, 136, 22, 52, 232, 143, 245, 156, 41, 202, 165, 130, 65, 62, 224, 80, 187, 28, 233, 167, 34, 114, 206, 190, 148, 145, 242, 142, 71, 78, 3

convert the hash to binary

take 0,4

you get 1011.

Don't think your hash function is right.

I get bf4b881634e88ff59c29caa582413ee050bb1ce9a72272cebe9491f28e474e03

they have stated that the bch was sent to btc address but the blockchain shows a bch address as the receiver but also the same address is linked to a btc account also but it shows as going through to th bch address. coinbase basically says its unrecoverable because it was sent to a btc address but the blockchain says otherwise.
There is no difference. The address is valid on both chains; however, coinbase has decided to only use the address for the BTC chain (presumably for operational integrity / security.).


i understand that. what would be my options moving forward?
as far as I know: there are none, other than what you've already done; that is to contact Coinbase and ask them to credit your BCH deposit.

I'm sort of out of the loop on this, but I heard (I think years ago) that coinbase was working on resolving this issue in an automated way.. Not sure though.

So yeah, there isn't much you can do. Perhaps if it's an enormous amount you can do some stuff with lawyers, but other than that... Not sure.

For future references, either don't use custodial exchanges and or double check where you are sending your coins to. Sad

If you sent BCH to a BTC address on coinbase, well, the keys belong to coinbase. They are the only ones who can help you recover them.

What you're looking for is their "Cross-Chain" recovery policy. I'm not sure, but i believe coinbase does not have one currently? This might change in the future, so your coins are not indefinitely lost (yet)

Quote
i looked up the address and it is linked to a btc and a bch account. upon further look the bch address has received the funds which should be correct, but it has not showed up in my exchange and coinbase has ststed that it was sent to a bitcoin address. if you look up the address it is associated with btc and bch but blockchain shows bch as the receiver(which should be correct).
A bitcoin address is also a valid bitcoin cash address. (well, starting with 1.. at least.)
