561  Bitcoin / Wallet software / Re: Is it Possible to Guess a Private key of Bitcoin Paper Wallet? on: April 22, 2021, 05:24:49 AM
For just knowledge purpose, I have created two paper wallets by using the same website btc-paper-wallet.com twice in one minute.
Don't use this website. It appears this website will not generate private keys on the client side (on your computer), but will rather generate the private keys on their server. Your private key will also be known to the owner of api.qrserver.com, if different from the owner of the website you are using.

So, can you please suggest a safe and secure site that is 100% trusted?
You can consider using bitaddress. You can generate a paper wallet offline while using the site offline.

I would suggest that you not use a paper wallet until you have some experience using bitcoin, and you are confident that you have a solid understanding of how bitcoin works, including things such as private keys, importing private keys, and the importance of backups.

563  Other / Beginners & Help / Re: Lightning bitcoin payment on this forum on: April 22, 2021, 04:06:27 AM
Or is lightning payment not yet safe?
That may be a small reason at this point but the main reason is that using LN doesn't make sense here. LN is useful if you are going to send/receive multiple payments with the channel you open. But if it is a one time payment every week/month then it makes no sense and it also costs more than the on-chain transaction.

Lets say your signature campaign wanted to do this, they have to:
1. Open a channel for this week/month 's payment which means sending an on-chain transaction to that channel (fee #1)
2. Send out the payment to each user on LN (a tiny LN fee for each tx)
3. Close the channel since there won't be any payment until next round (fee #2)
4. Each user (or at least most of them) that receives the payment has to close their channel and move the coins to their wallets (fee #3)
This means using LN in this case replaced 1 on-chain fee with 3 on-chain and a tiny LN fees which makes no sense.
Fee #2 will not be necessary because the payor can receive a LN payment to make the following week's payment. Similarly, Fee #1 will only be required the first time a payment is made.

Fee #3 will apply to anyone not intending on keeping the bitcoin in the LN network, in which case a LN payment would probably not be appropriate.

Go ahead and send the $65 in litcoin to the above address, and post the bitcoin address I need to fund the loan to.

Thanks.
565  Bitcoin / Bitcoin Technical Support / Re: Any solution to broadcast with reduced fees? Maybe any other suggested network? on: April 22, 2021, 03:47:31 AM
You could use some kind of "wrapped" bitcoin that uses another blockchain, and is easily convertible back to bitcoin. The problem with this is that you are essentially forcing your payees to bear the cost of the fees.

Setting the fee to 30 sat/byte is probably below the lower bound fee rate at which you should expect to have your transaction confirm anytime soon. The reality is that fees for sending on-chain transactions is very high currently.

Others have mentioned that you can send a single payment after a month that represents 4 weekly payments. I think this is probably the best option, and would effectively reduce the fee you are paying by 75%.

If any of your participants are willing to accept a LN transaction, you can pay via LN, but I would say that you should not force this. You can add incentives for accepting a LN payment, such as offing a small bonus.

It might also be a good way to find yourself becoming a victim of a $5 wrench attack.  If it was just for a few hundred bucks, then okay that may be a cool way to trade bitcoin, but I wouldn't take this risk for anything over a couple grand.  YMMV.

I guess I'm kinda skeptical about informing complete strangest that I own bitcoin.  Other than my immediate family and few very close friends, the only people who know I'm into bitcoin are you lot.
There are a number of methods you can use to trade bitcoin in person for cash while still maintaining your privacy and security. I've done a number of trades with complete strangers which have gone smoothly.

  • Only trade with someone in person who has a history of numerous trades and plenty of positive feedback.
  • There is no requirement to share any personal details with them whatsoever. Simply pick a time and place to meet, and some sort of physically identifying information (I'll be wearing a blue Yankees cap, for example).
  • Meet in a public place with plenty of other people around. You can also go for somewhere with lots of CCTV if you like such as a big shopping mall or a major travel hub (such as an airport). You can also meet directly outside a bank which either the BTC buyer can withdraw cash from immediately prior to the trade, or the BTC seller can deposit cash to immediately after the trade. Doing this eliminates the risk of counterfeit bills.
  • Bring a friend with you. If legal in your jurisdiction, bring something for self defense.
  • Only take with you the exact amount needed to complete the trade, be it in fiat or BTC.
Trading in an airport, past security would help with protection from theft from your trading partner, but might risk theft from the government (via asset forfeiture) if you are dealing with large amounts.

Other than trading in an airport (past security), there will always be the risk that the other party claims to have a gun in his pocket that is being pointed at you if you don't comply. To any bystander, or any CCTV camera, the interaction will be nothing more than two people talking. In this case, even a weapon of your own will not do much to protect you if you don't want to risk getting shot in the process.


My suggestion to the OP is to wire money to coinbase as opposed to sending it via ACH. This will speed up the time the funds will be available for withdrawal. Other than my suggestion, there is really not much that can be done to speed up funds availability without sacrificing cost, an ATM for example will take a (usually large) spread or fee.

I haven't looked at the new forum software in depth, but I can assure you that it does not use JS based frameworks on the front end. The new forum software ultimately will have a div that displays the post content, just as the current SMF forum software does.

False. It does not render shit without client-side JS.
That is surprising. I guess that means those who want to avoid using JS will have to use the API, or a framework that leverages the API.
569  Other / Beginners & Help / Re: Lightning bitcoin payment on this forum on: April 22, 2021, 02:31:35 AM
Or is lightning payment not yet safe?
Yes LN payment is safe. The current bitcoin economy does not currently allow for LN payments to be efficient.

In order to receive a payment via LN, you need to either have spent money on LN or have someone else open a channel with you that gives you inbound capacity (usually for a fee). Also, if you receive a payment via LN, it will generally mean you intend to spend most of that payment in the near term, otherwise you will deplete, and eventually exhaust your receiving capacity.

Some bitcoin merchants accept LN payments, but most do not. Personally, I would be open to receiving LN payments if I had inbound capacity, and intended to spend bitcoin at a merchant that accepts LN shortly after receiving the payment, but absent these two requirements, I would tend to prefer an on-chain transaction.

I kinda like this board as dated as it is. Change is always jarring when you've been used to something for so long.
Me too, I'd hate to see all user-scripts (my own and from other users) broken because of a forum upgrade. If would probably take me months to update everything, and I'd probably abandon several of my old projects.
If all the IDs in the HTML remain constant, moving to the new forum software shouldn’t break most scrapers.

If your code is structured in a way such that each function does a single task, it shouldn’t be terribly difficult to update scripts based on the new forum software.

Except new forum software rarely keeps IDs constant because each forum engine has a completely different way of rendering things.

Imagine if this forum moves to some JavaScript based framework like Invision, where the pages and content is loaded dynamically. Then we (yes we, I also have scripts) have to somehow patch our scripts to call the JS functions that return the items we want to scrape and it's too much legwork when all you had to do before was search for HTML tags.
I haven't looked at the new forum software in depth, but I can assure you that it does not use JS based frameworks on the front end. The new forum software ultimately will have a div that displays the post content, just as the current SMF forum software does.


I know there are a set of intended APIs for those that want to retrieve information from the site. Wondering if that will be the mandatory path, as opposed to scraping, due to things as the above.

The API allows someone to query posts by user and by thread. The API documentation is somewhat confusing, but it appears both the username and thread are strings, as opposed to both being ints currently. I haven't looked deeply at the code to see how a thread ID is created.
571  Other / Meta / Re: Reporter Statistics on: April 22, 2021, 02:02:33 AM
Bump.

New achievement. Today I got to the mark in 40 000 sent reports.

Congrats. Keep up the good work.


Maybe theymos could implement some kind of dashboard that updates every day (or however often to not overload the forum's database and other resources) regarding reporters. I would think he would periodically query information about reports, as part of the forum administration. This could be similar to the merit stats, except the stats would not load when someone clicks on the report.
572  Other / Politics & Society / Re: Virginia Police Officer Fired After Making A Donation on: April 22, 2021, 01:56:19 AM
The Police officer is a member of the union, and the union will fight for the officer to get his job back. I have not reviewed the union contract, but I strongly suspect the officer will prevail.

The firing was clearly political. Also, news that the police officer donated to Rittenhouse's legal defense fund, and the comments that he made while donating clearly violate Twitter's "hacked materials" policy, yet Twitter has allowed stories to remain.

The hacking of the website that is hosting Rittenhouse's legal defense fund was obviously done with the intent of harming people who are trying to help Rittenhouse have the resources to ensure he has a fair trial.

Are the phishing sites from the same websites? If so, the admins can automatically change the link that newbies post to “suspicious link”.

Another option would be to add a warning to any post a newbie posts with a link advising to verify that the link is correct.
I don't think they're all the same sites.
Not sure if this is the OP's case but back then I recall reporting some bots posting Reddit links in the Bitcoin Discussion with suspicious links inside the post that I didn't even bother to click.
They were taken care of in <24 hours.




A 24 hour turn time for phishing links is probably too long. IMO, a better SLA would be an hour or two. If necessary, the admins should invest in a way to get the turn times down to a few hours. This could mean investing in AI or software that will censor posts based on logic, or it could mean hiring additional patrollers.

576  Bitcoin / Mining speculation / Re: $100 billion to be invested to increase chip fabrication capacity! on: April 19, 2021, 01:30:50 AM
What does everyone here think about this
There is a huge chip shortage globally currently. Some have attributed this to Covid, but I am not sure.

The chip shortage is affecting everything from cars to computers to miners. The cited investment is an attempt to increase capacity to bring to closer to in line with demand.


A large chunk of the chip capacity is in Taiwan. I would be more concerned about China invading and/or attacking Taiwan when it comes to chip capacity.

578  Other / Meta / Re: Is it possible to get the copper membership using lightning? on: April 18, 2021, 03:32:54 PM
This is not possible yet, but IMO it should be a priority for theymos to implement.

IIRC, theymos has declined to implement LN because of the tax implications of running a LN node -- you would need to keep track of the bitcoin price anytime you received a 10 satoshi payment, and reported the <$0.01 payment accordingly. The above could be done via automation using a major exchange's API, or the forum's LN node settings could be set so that no LN fees will be charged for users to route transactions through the forum's LN channels (or the fees could be set insanely high).   
579  Other / Meta / Re: Get Notified when quoted - on forum feature on: April 18, 2021, 02:11:45 PM
Wouldn't that be helpful?

Yes, I totally agree with that. Most forums have a similar system and I am surprised that this one does not have one. I'm surprised it's for a security issue as @Quickseller comments but I suppose there is some reason like that.

Anytime you introduce new functionality, there is the possibility it will be exploited. Years ago, the ability to upload an avatar was exploited and said exploit was used to hack the forum. There are many forum members who have the ability to and are willing to create user scripts that will give the functionality that forum users want, and these user scripts will not present the same potential security risks.

Implementing additional features directly on the forum means there is the potential for additional security risks.
Can't you afford high-end software security engineers when you hold hundreds of bitcoins :/
See my above comment.

I want to know normally how long this recover process takes to finish ? I mean 1 month is normal for this. 

I am wondering because of I have very little technical knowledge
..
Why does it take so long? Is it a very difficult process?

Thanks everybody.

The process itself is not difficult. The difficult part is doings it in a way that protects the private keys of the exchange. Most likely, the private keys of the various coins they support are kept separate, and the devs probably need to perform ETL tasks to move the private keys from the infrastructure of one coin to another. This is most likely done on an ad-how basis, and many tests and approvals will likely be needed to ensure that no information is leaking and that customer money is kept safe.

I would anticipate a delay lasting months, hopefully it won’t be that long. You should follow up with them periodically. Posting in this forum will not accomplish anything.
