1  Bitcoin / Project Development / Re: Anyone up for Beta Testing a Prototype on Lightning Network? on: September 29, 2022, 05:48:42 PM
The preimage exists ONLY when you settle an invoice.

I did. and his response is that I am somehow tampering with the preimage. But the preimage is generated by the paying customer's lightning node, nothing to do with me!
And as said before. When you pay an invoice, the call goes through YOUR WALLET SOFTWARE, which connects to a node THAT I DO NOT OWN. So how could I possibly tamper with the preimage generation?

FWIW this is all false.
Yes it's true the preimage for us only "exists" is known once the invoice is settled, because YOU have to reveal it in order to claim the payment that was made to the payment_hash (a hash of the PREIMAGE)

The preimage, so in fact, the input, is generated by lightning and nothing to do with us. Hence fair.
It's generated by your lightning software, but various implementations will allow you to set a custom preimage, and even if they didn't there'd be a way to do so.

I am open to tweak my implementation if it can be proven unambiguously that a seed off a preimage can be tampered with, based on my current description of matters
Since a preimage is really just the equivalent of a random sha hash, you could start with a good secret and then make a hash of a hash n times, and replay that. Once the new bet is placed you can reveal the old hash to everyone in order to prove you're not alternating between hash chains.
Now that I think about it, this might be less than ideal since the kth+1 hash will be the payment_hash of the kth hash, though I don't see how this could be exploited really, just a funny gimmick.

I think you genuinely seem to misunderstand how payments are done through the lightning network, so I don't really get all the negative vibes in this thread here.
2  Bitcoin / Wallet software / Re: multi account wallet for business on: August 19, 2022, 10:36:08 AM
the idea is simple, I need the user to have his own address where he could receive the crypt, preferably not limited to one currency and then on the site he could make transactions with other users (transactions on the site, of course, simply by rewriting from one database to another without blockchain
) and then he could withdraw it from main balance of the site, the database will simply keep tabs on how much money this person has.
If you want multiple currencies you should probably look into a payment processor such as coinpayments or btcpayserver.
If you just want BTC, use bitcoin core. Assign an address to a user and enable walletnotify. On deposit you will get notified and you can process the deposit however you like. Should be scalable.

SQL Table would need the following table:
1.    TestUser.      WalletID. AddNow.    0.00234.         0.00233.          1TX.                     1/1/22 1:0:00

Well if you need SQL support, then you can't use JS in the first place since it has not-so-good support for databases anyway. Getting a PHP developer would be the better option (PHP and JS tend not to mix very well).

Huh Mysql and NodeJS should work perfectly fine?
OP you should do this yourself unless you want to shell out a couple thousand dollars. Run a full node, choose a language (JS) and enable walletnotify.
Assign address to user and let walletnotify hit a certain internal route (/make-deposit) where you credit the deposit and store the new balance in your DB.

The developer also has total freedom, so don’t need to use my recommendation - use any method to achieve the functionality I describe.
Bad idea. the work will be half-assed and you will have no idea whether or not it functions correctly.
If I were you I would look into btcpayserver for certain deposit logic and then just keep track of balances using mysql.

Looking to hire a developer to create a simple user registration and management system, with an interface to a Bitcoin wallet.
This is not simple. You're asking someone to write a front-end that has sound registration logic, so a backend and mail server? and crypto payment logic. If you want this done well it's gonna cost you.
4  Alternate cryptocurrencies / Service Discussion (Altcoins) / Re: Tornado Cash mixing service is now blacklisted in US on: August 18, 2022, 03:14:26 PM
Pretty sure this guy was arrested earlier. I think there's actually two people of age 29 that got arrested, one of whom being the developer of TC.

So, I think that there is another important thing that might have to be discussed although we will probably never know:
- Was tornadocash compromised since launch and it didn't offer the claimed privacy at all?
I have a really bad feeling about this, I can remember how the alpha bay then hansa market episode went.
You can use google ?
I'm pretty sure at least some people have audited the contract code since then. Tornado cash was fully decentralized, non-custodial, unlike most of these garbage mixers. perhaps there is a way to backdoor the cryptography they use (zk-snark), no idea.

Does this thread answer your questions?
6  Bitcoin / Bitcoin Technical Support / Re: Is it possible to reveal / prove the amount of bitcoin in a lightning address on: February 01, 2022, 07:21:37 PM
My question is: I know the lightning network works differently, but would there be a way to "prove" I own a certain amount or even revealing the balance? If so what would be the process? Sure I could publish somewhere the balance but then again you would need to trust me to publish the right number.

Hmm. It's not foulproof but I guess you could publish all of the received individual donations in terms of invoices (and sum the amounts)? If you exclude a certain invoice then that would be proveable by the individual who paid the invoice as he could reveal the invoice (which is routed to your node's pubkey) + secret?

Not sure what this would prove as it does not at all imply that you used the donated funds as intended, something that could much easier be tracked if you were to be using an on-chain address.
though here you could also most definitely probably publish the invoice of it going to charity xyz's node (along with the secret to prove it was infact paid)

Users can currently send/post incorrectly quoted messages to assist in scams or discredit other users.

This could be addressed by having a hash generated based on the content of a message, and then a checksum implemented to reject invalid quotes from being sent/reposted.
I mean it would be a cool feature notwithstanding that I personally have never seen a case where this could have prevented anything. Critical reading skills should prevent people from getting away with misquoting people, and lying about the contents of dms (or denying the existence thereof) would just cause a standoff where one party would look silly after theymos or any moderator? checks their PMs.

I'm guessing this might not happen in low-profile cases which I imagine would be the only reason something like this might be useful, but really in 99% of the cases it is immediately obvious who's the scammer and who's the actual affected party. And again, if it turns out to not be that simple I imagine it would not be that hard for a mod to check the pms manually.

I think the threat alone of an admin checking the actual contents of a pm would already make manipulation with on-site communication (pms) fairly unattractive, especially for more senior users. And really, wouldn't such a feature just cause a shift to other messaging apps like Telegram? Hard to see what exactly would be solved.

Perhaps development efforts would be better spent on finally making it look like this forum didn't come straight out of 2007, and more like their modern counterparts.

For example, if you open "wallet.dat" file (for example Notepad++)
we will see "timesmart 1613256165" and my question Is it possible
to convert a Bitcoin Core "timesmart" into human-readable format?

seconds since epoch?

10  Bitcoin / Project Development / Re: Partners/Staff/Sponsorships! MASSIVE SMM PROJECT BEING LAUNCHED! on: January 09, 2022, 09:02:23 PM
I have always been curious: do you have some sort of custom software with proxies that creates social media accounts and then have workers fill in the recaptcha and then you use those accounts to complete orders, or are you a reseller from another panel?

Or is it some sort of botnet where you use other people's legitimate social media?

Anyway the only thing that matters for these panels is price. Market is completely saturated with a lot of big players with bigger pockets than you. It seems to me that you're reselling? Gonna have a hard time.

12  Economy / Web Wallets / Re: Password requirements on: December 23, 2021, 06:12:53 PM
I probably know the symbol en numbers. And i do know a list or pool of passwords i commonly used. But it is very important for me to know when the password manager went from ‘medium’ to ‘strong’.
If it's any help i'm pretty sure that uses nowadays for their password strength guesstimation. Not sure if they also did so back in 2014 though and how it is implemented.
13  Bitcoin / Bitcoin Technical Support / Re: Need help setting up Bitcoin Core full node over Tor hidden service only. on: December 04, 2021, 04:44:59 PM
I don't fully understand the issue, from the looks of your debug.log your RPC can't bind to the port specified in your bitcoin.conf (which is also the default port, so the command is redundant?), though it seems that this has not interfered with the syncing of your wallet and thus does not relate to your networking issues?

It's been a while since i prodded around and I currently don't have my node synced to try and replicate this getnetworkinfo output

The only thing I can think of is that the
is not correctly cancelling out the

Or that your conf file is indeed not loaded at all.

Reduce the number of parameters to just
-onlynet=onion -bind= -listen=1 -proxy=
and see if that resolves the issue.

How can this be fixed? I did check DB in terminal and have found the correct table with the correct params saved inside it etc, but why is node not able to get those params.
Parse the json? (.json())

15  Bitcoin / Bitcoin Technical Support / Re: Sending amounts > in wallet empties wallet on: November 23, 2021, 05:44:16 PM
So you're saying that you are the one who initiated these transactions with 1 Input -> 1 Output and are just wondering why the fees are so high, basically?

As well now,  who has control over this wallets that received this fees.

Uhh, the miner that mined your transaction?

So the question is has anyone had this experience with using this app to control transactions of there wallets ?  

http://de.schildbach.wallet/ ? Never heard of it and it won't load either. If this wallet does not allow you to set custom fees I would suggest switching.

edit: seems to be a pretty respected Android wallet.
16  Other / Off-topic / Re: Node.js help needed on: November 23, 2021, 04:29:09 PM
you need to define rows (const rows = client.query) before iterating

or maybe you can do what you're doing right now but use for r in result ?

But, errrm, what does this have to do with bitcoin? Don't think this is a general technical discussion board. Use Stackoverflow in the future.

The developer I work with have been stuck with this issue for few days now and I need help from someone experienced in js to answer this.

I seriously hope you're not paying him per hour
17  Economy / Service Discussion / Re: no-kyc hedge fund? on: November 22, 2021, 09:21:02 PM
Something like Arakne bot is the closest that comes to mind but you probably want to avoid these kinds of trading with your funds unless you know who the operator is.

And more traditional "stockmarket-trading" using crypto obviously don't make much sense on a large scale given the regulations one as an operator of these hedge funds would have to deal with.

Personally I would also love to see real BTC/Stock pairs (I think there was an exchange in the past kinda offering this, but required kyc, forgot their name) but I highly doubt we will ever see this in a decentralized/kyc-free fashion (probably when hell freezes over Tongue)
18  Bitcoin / Bitcoin Technical Support / Re: Bitcoincore has lost blockchain/wallet? on: November 06, 2021, 04:47:01 PM
Should probably give a bit more info, I assume you're using the GUI?

If you don't open the wallet for a couple weeks it seems logical to me that it might show that it is out of sync, because it is.

Both Bitcoincore, wallet.dat and block chain are on a external driver
I assume you didn't change the paths inbetween now and when you succesfully used the wallet for a couple months?

A command-line approach (what I would do) would be to first check if your bitcoin core instance is synced. then load the wallet.dat and check the balance.

So start bitcoind from command line using whatever bitcoin.conf or startup options concerning your paths to your external drive,

bitcoin-cli -rpcuser=<user>-rpcpassword=<pass> getblockchaininfo


bitcoin-cli loadwallet "test.dat"

Hm. This is probably not ideal for a beginner.

What you should do is back up your wallet.dat to a secure location before you do anything. If nothing works out you can always load the wallet.dat in a fresh core download and export your private keys to your inputs manually to another wallet such as electrum.

Load your wallet into unsynced bitcoin core > console > start generating receive addresses / raw change addresses > export private keys int electrum?
I assume this process is deterministic and at some point you should've exhausted all used addresses? Someone should comment on this. There's probably an easier solution to your problem though, so maybe just ignore this post.

19  Bitcoin / Project Development / Re: New project ( need help ) It's a unique idea and a new concept on: November 05, 2021, 08:59:01 PM
Now what I will say for sure will sound stupid, but last night I have a dream, a bad one! I just realized that big money is not for me.
It sure does. You made a token you can earn by playing a non-existing game because you lost money in a HYIP? Hahaha

I did that, I start to use drug after I made only 1k, I start to act like a dick and stuff that I always thought is cool.
I think you are still on drug!!!?

I just realized that big money is not for me.
Roll Eyes

I lost everything because of that vacation.

Wrong. You lost "everything" because you speculated on a HYIP.

Now, I want to offer the project for free to someone capable of doing this! I will donate the project.
I will offer anything and everything I have because by the end of the day I just want to see it happens and I also hope I will contribute into the crypto world.
So basically you're "giving away" a template site and your unique idea which is what exactly?

Well I guess that is more or less what this section is intended for.

I ignored it. It worked fine. Thank you
Seriously did you even read my suggestion? this sythe thing seems like some complicated P2P trading forum, which is dead anyway (only a couple active threads in the csgo section)

I posted two very active market places as an alternative to the steam market. Highly recommend you use those if you have no idea what you're doing instead of getting scammed on some esoteric forum.
