In theory, a security researcher might find vulnerabilities in that HW wallet that would allow someone to make a copy of the HW wallet so someone can at least brute force password attempts.

The article claims that there is a person who says he can do it in 6 months with a 10% commission, but I do not know if the owner accepted the proposal - I did not find the news that he managed to get his BTC back.

Quote
Following the publicity of Thomas’s plight, Alex Stamos, an internet security expert at Stanford Internet Observatory, said he could crack the password within six months if Thomas gave him a 10% cut of the digital fortune
Anyone claiming to be able to help him would need to demonstrate their ability to clone the data on the device. Once the data has been cloned once, it becomes trivial to clone it an arbitrary number of times, and it becomes possible to brute force the passphrase. Obviously, the person would need to have some idea as to what their passphrase is.

If someone is at least somewhat reputable, and can demonstrate the above, I think it would likely make sense for them to agree to a 10% proposial.
462  Bitcoin / Development & Technical Discussion / Re: Help; Would Merkel tree solves problem of Collision encountered with SHA256 on: May 15, 2022, 01:45:52 PM
My question isn't about making Collision but can collision (process whereby hashing of two or more different keys gives the same hashing value or result) be totally eradicated with this method of Merkle tree
It is impossible to entirely eradicate the potential for a collusion when using a hashing algorithm. Otherwise, you would just be dealing with raw data.

Given the limited number of blocks, and the algorithm currently being used, the chances of a collusion is effectively zero under the status quo.

1. Would Merkle tree solves the problem of Collision sometimes encountered with SHA256?
What do you mean? There's never been a collision with SHA-256.
There are 2256 possible outcomes when hashing a piece of data using SHA-256. There is an infinite number of data that can potentially be hashed, therefore, there is an infinite number of data points that will produce collisions when hashing each of the data points using SHA-256.

With that being said, actually finding any of those collisions is a different story, and it is unlikely that someone will ever encounter a SHA-256 collusion without breaking SHA-256.
463  Bitcoin / Development & Technical Discussion / Re: Empty blocks on: May 15, 2022, 01:19:21 PM
There really isn't any incentive to include transactions in blocks.
There are transaction fees.

The miners have an incentive to maximize their immediate revenue because their equipment has a limited useful life.

Including an additional transaction into a block does have a cost because the miner needs to validate the transaction is valid, and for each additional transaction included in a block, it will take an incremental additional amount of time for the block to get propagated to the rest of the network.

Based on orphan rates of under 1%, and according to BlackHatCoiner above, a ~1.7% rate of total block rewards being made up of transaction fees, the theoretical maximum cost to include any transactions is below the revenue generated by including transactions. As such, including transactions is EV positive.



It is difficult to know with certainty if the timestamps of the block in question and the prior block are accurate. Timestamps can be up to two hours off and blocks will still be accepted.

To answer the OP's question, for whatever reason, the miner that found the block in question, ViaBTC, was unable to construct a block that includes transactions after they received and validated the prior block, prior to them finding the block they found.

Even if it is the former, it would be unusual for a company to use data from their paying customers for other commercial purposes.
Lol what? Not sure if I've misunderstood you here or you are being incredibly naive? Pretty much every big business is monetizing your data, from Coinbase to Coinmarketcap, from Facebook to Google, from your health insurance provider to your streaming content provider.
Not many people pay to use CMC, Facebook, nor Google. I am not sure how you think health insurance companies or Netflex are monetizing customer data.

Netflix makes suggestions based on your viewing history, in part in an effort to get you to use their platform more, but that is hardly "monetizing" data. I am sure that health insurance companies use analytics to try to improve health outcomes, detect fraud, and find efficiencies.
465  Bitcoin / Development & Technical Discussion / Re: Price Stabilization Algorithm/Protocol/Transactions on: May 13, 2022, 11:38:29 AM
It is not possible to use algorithms to force the price of an asset to remain stable. Look at what is happening with TerraUSD/Luna right now.

It is best to acknowledge that bitcoin has no specific underlying value, nor is it backed by any specific assets, but rather that its value is set by the free market based on the market's perception of its value, and usefulness to its holders.

To be honest, this person is harmless. I don't think even a neutral tag is necessary. No one is going to confuse this person with achow101.

If this person continues participating in bounties for a year, I have serious doubts that he will even notice they have negative trust, and it is unlikely he will even try to converse with any other forum member. I think it is most likely that this account is some kind of bot, as I believe to be true for many of the accounts that participate in bounty campaigns.
467  Other / Meta / Re: Proposal: Adding grey underline in every links on: May 13, 2022, 09:56:18 AM
So it appears the OP has found a way to hide the fact that there is a link within a post.

If all links were to look a certain way, someone could simply format their post to hide any links in their post. Although, forcing a link to look a certain way would make any hidden links stand out more.

I think the main reason why someone would want to hide the fact they are posting a link is for black-hat search result reasons (aka backlink spam). However much of the backlink spam is already more or less nonsense and these types of spammers do not need their posts to be up for very long.

The US is one of only three countries that allow for abortions past 24 weeks. The other two countries are China and North Korea.
This is just not true. Most Western countries allow abortion beyond 24 weeks in specific circumstances. Here are a handful I know off the top of my head:
All of the examples you cite allow for abortions in only limited circumstances. In the US, it is possible to have abortions for elective reasons. The two are not comparable.

As a moral issue, I really don't see any valid argument as to why late-term abortions should be allowed
So it's perfectly fine for a woman to die from health complications as a result of her pregnancy?
You are referring to edge cases. Most late-term abortions do not meet this criteria. I also understand that there was language inserted into the bill that recently failed in the Senate that used "health complications" as a loophole that would effectively legalize abortions up to the moment of birth for elective reasons.

Any exception that allows for late-term abortions would need to meet a very high standard, such as the requirement that new information was discovered that was impossible to have been known prior to the threshold cutoff, and there being a substantial risk to the lift of the mother.

As a moral issue, performing a late-term abortion because there is a risk of health complication for the mother is doing something that is guaranteed to end a baby's life that merely reduces the risk to the mother's life, when it was not certain that the mother was going to die from the pregnancy.

As a constitutional issue, there is no basis to guarantee the "right" to have an abortion.
So if it didn't exist in Philadelphia, 1787, then it's fair game?
The constitution has a means to be amended if there is the will of the people to amend it. If there is insufficient voter support to amend the consitutition, the only reasonable conclusion is that the people who are governed by the constitution have not consented to changing the consitutition.

There have been various supply chain issues since covid started over two years ago, although they have gotten worse as of recently. I agree that markets will eventually adjust and supply chains will originate from elsewhere, although China is also the source of certain materials that is not available elsewhere.

In any event, China likely is going to invade Tiawon during Biden's presidency because it knows that Biden is too weak to respond militarily. They may be waiting to see how the situation in Ukraine plays out.

Yes, it is hard to decouple from China immediately same way it's hard to suddenly stop oil from Russia. It'll take time to bring production back to the US for example.

As for the invasion, that's a possibility. They wouldn't wait for the Republicans to come back to the White House.
It is much easier to transition off oil/gas from Russia than it is to transition off of imports from China. The energy that is imported from Russia is already produced elsewhere throughout the world, and these places just need to increase production. Much of what is imported from China is largely only produced in China, so manufacturing will need to be setup elsewhere.

I think it is probably safe to assume that China (and Russia) has compromising information on Biden, which is why he has been so soft on both countries. I can't see Biden significiently pushing back against China in response to an invasion of Tiawon.
470  Other / Meta / Re: The situation with Ukraine and the accounts that supported the war. on: May 12, 2022, 04:45:48 PM

I don't think your list is even accurate. I follow some of the people's posts that you cited as being "pro war", and some of them have never commented on the Russian invasion. I don't think refraining from commenting is the same as "supporting".
Support by merites or in any other way is also support.
I am not sure what you mean by "merites". It appears that word may be French, and the translation into English does not make sense in the context of what I wrote.
471  Economy / Service Discussion / Re: Robinhood to enable the lightning network on: May 12, 2022, 04:43:02 PM
The reason for this is because consumers will ultimatly act rationally and in their own best interest
Rational consumers will act rationally, but the fact that we have literally tens of thousands of complete scam tokens and coins that people continue to lose their money on, and we have 100% proven scam exchanges like YoBit still operating, proves that this space is filled with irrational users. If any service thinks they can largely get away with doing something which will harm their user base in order to make themselves more money, then they will absolutely do that. Robinhood is a great example. Other examples which spring immediately to mind are Coinbase selling customer data without users' knowledge or consent, Binance tricking newbies in to buying some fake bitcoin token on their centralized scamchains rather than actual bitcoin, and Wasabi implementing censorship in their wallet. Plenty of people don't even know these things are happening, let alone actually care about them.
People use YoBit largely for one of two reasons. One, because they are not aware they are a likely scam exchange. Two, because YoBit does not scam all their customers, and their scam is one such that it is possible that some of their customers will make money while participating in their scams -- in other words, customers are gambling.

You mention that some customers do not care that companies are doing what you believe are negative actions. None of what you describe removes all value from the products the various companies offer. The free market will handle these negative behaviors.


Companies will offer what makes them the biggest profit.
Consumers will usually buy what appears to get them the best deal for the money.
I think your bolded statement agrees with my statement. If a consumer is not going to buy what does not get them the best value for their money, the company is going to be unable to realize sales from a product with a bad value.
472  Other / Politics & Society / Re: [report]Rov V Wade overturned on: May 12, 2022, 04:16:43 PM
According to recent unconfirmed reports, including a reported draft opinion of the US Supreme Court, Roe v. Wade is going to be overturned by the US Supreme Court.

If the above is correct, abortion will be regulated by the various states, and in most states, abortion will not be illegal in all circumstances.

It appears that the SCOTUS correctly recognizes that there is no basis to say that the "right to get an abortion" is enumerated in the Constitution, and as such, the ability to regulate abortion is reserved to the various states.


What do you think? Is there any basis in the US constitution to suggest that the right to an abortion is guaranteed in the Constitution? If true, is the above ruling consistent with the Constitution?
very supportive if it is held in the United States against the Constitution, especially regarding abortion, the freedom of the population to do so is highly respected there, that position becomes a reference for free sex there, cohabiting, we remember what happened to Will Smith's family who put forward the wife in home,  Indeed, some countries strongly oppose this abortion because it is not in accordance with religious norms, morals, state regulations, but why not?
The US is one of only three countries that allow for abortions past 24 weeks. The other two countries are China and North Korea.

As a moral issue, I really don't see any valid argument as to why late-term abortions should be allowed (dito with post-birth abortions). I understand the argument for earlier term abortions, and in most places, the support for early-term abortions is likely strong enough such that early-term abortions will remain legal.

As a constitutional issue, there is no basis to guarantee the "right" to have an abortion. There is a litany of other issues that the states use their police powers to regulate regarding behaviors that people do in their own homes and what people do in their doctor's office.

Again, I am not sure how one could argue that apple does not support bitcoin payments on the iPhone. It is already possible to use a wallet app on your iPhone to send/receive bitcoin (and most altcoins). How else could apple support bitcoin payments?

In that case we can say that every device that supports the installation of a crypto wallet supports Bitcoin or some other cryptocurrency? The point here is that Apple could/should accept Bitcoin as a means of payment for its products, so customers could pay for everything on this site with Bitcoin. Given that some important shareholders of a company like Buffett are against Bitcoin, I don't see how and why Apple should accept Bitcoin at that level.
Yes, I would generally say that most (every?) mobile devices have support for bitcoin/crypto.

You can currently buy Apple gift cards on bitrefill (and other crypto to gift card sites) using your crypto. I don't see Apple accepting bitcoin directly for their products because doing so would only add to their compliance and sales support costs, and probably would not bring in many additional sales they would otherwise have.
474  Bitcoin / Wallet software / Re: CoinJoin Alternatives to Wasabi on: May 12, 2022, 03:29:11 PM
It is possible to trace CJ transactions and has been for quite some time.
That might be true, but there is no denying that Wasabi coinjoins will be under much greater scrutiny than other coinjoins, since Wasabi are actively paying a blockchain analysis company to monitor their coinjoins and tell them if they have to censor any specific inputs.
Are you sure they are giving a list of inputs to a blockchain analysis company, as opposed to getting a list of addresses/inputs that should be blacklisted that they can compare proposed inputs to?

Even if it is the former, it would be unusual for a company to use data from their paying customers for other commercial purposes.

The broad use of such tools as Mercury wallet or coin swap may help to make blockchain's transparency a less reliable source of information for undesirable observers.
I completely agree, and I've said as much before - if everyone just started mixing their coins as their standard practice, then the concept of taint would disappear overnight and bitcoin would be completely fungible. Every centralized service would either have to accept any and all bitcoin, or go bankrupt. Bitcoin would be completely fungible, no one would end up with accounts being locked for arbitrary reasons, blockchain analysis companies would be useless, everyone would regain so much lost privacy, and the whole ecosystem would be far better off for it.
Not necessarily. With the exception of CM, researchers have been able to trace inputs to outputs from all major mixers, and have published their results. CM uses countermeasures that would prevent inputs from being linked to outputs using methods described in public research, however, in theory, the inputs may be linked to outputs (assuming of course CM is not actively keeping track of inputs/outputs pairs and/or is some kind of honeypot).

Anything that China releases to the rest of the world is intentional. Any "zero covid" strategy is not going to work. There are simply too many reasons for which humans much interact with each other in order to survive. I agree that any numbers released by the Chinese government should not be trusted.

It is possible that China is intentionally messing with supply chains to make it more costly to sanction them once they decide to invade Taiwan.

If they really are doing this, then they better start with the invasion quickly. Supply eventually expands to meet demands. It can get to the point where by restricting your own supply it'll encourage production elsewhere.
There have been various supply chain issues since covid started over two years ago, although they have gotten worse as of recently. I agree that markets will eventually adjust and supply chains will originate from elsewhere, although China is also the source of certain materials that is not available elsewhere.

I'm not completely sold on the theory that large Bitcoin sells / buys affect the mempool, since a large portion of people still hold their funds on exchanges so they're just buying and selling 'paper Bitcoin'.

But statistics do suggest such a correlation exists and I'm very happy to see that, especially if we start seeing it more and more over time, since it would suggest higher percentage of users (or maybe just investors?) taking custody seriously and stopping to put their trust in paper Bitcoin.
If large swings in bitcoin are causing people to move coin to their exchange (and causing the mempool to get more congested), so they can sell, it would mean that people are holding their coin in their own wallets, only to entrust the exchange when they are ready to sell.

I don't think this is quite the same as holding their coin in their own wallet, and trading directly with whoever they want to trade with.

You could potentially edit your post if you created a thread outside of auctions and subsequently moved it into auctions. There are also auctions in the collectibles section whose posts can be edited/deleted.

If you were to move a thread out of auctions, if the thread is appropriately located in the other sub, the OP should have the ability to edit their posts.

Blockchain analysis is ultimately a process of deduction and induction.
A process which becomes much easier when the centralized coordinator is actively working with blockchain analysis companies and handing over all the data they collect.
