As I noted in my above post, you ultimately need to store all information required to access your coin, including any passphrase, and additional keys if using multisig. You can store this information in multiple places if you so choose.
Which is exactly where a tamper-evident set up is useful. I don't want someone to be able to compromise one of my back up locations and for me to have no knowledge of it. Some of my back ups are for cold storage coins I haven't touched in years and don't plan to touch for years. Do I really want a period of 10+ years with an attacker knowing my seed phrase and attempting to brute force my passphrase, find its back up location, or both, and me having absolutely no knowledge that that is what is happening? Of course not. Even in your hypothetical situation of me only checking my back ups very rarely, a period of few months before I discover the breach is far better than not knowing about the breach at all.
Everyone has a finale budget for security. I think it would be better to invest whatever you would spend on the tamper evident bags on a more secure/better safe, or other equipment that will prevent an adversary from accessing your seed.

If an adversary is able to access one location storing a portion of your seed, they will likely make a serious attempt to access your other locations. I think it is probably reasonable to expect them to do so within half the interval that you would normally access your off site location.

If you insist on having something in place that alerts you of a potential compromise, I would suggest something that alerts you right away. I think a tamper evident bag is really not much more than a false sense of security. Given enough time, an adversary may even be able to replace the bag, making it appear there was no compromise.

Similarly, if you are in a dire situation, you should be willing to accept experimental treatments to potentially result in a positive outcome.
You should be willing to accept experimental treatments as part of a controlled trial, which have appropriate lab data to suggest their efficacy, which have been through appropriate safety studies, are produced in a controlled and safe manner, and are given by trained professionals at an appropriate dose in an appropriate setting to deal with any unknown or unforeseen side effects. You shouldn't experiment on yourself with random chemicals because a stranger on the internet told you to. Again, the two are not comparable.
Ultimately, scientists need to experiment to determine what the "appropriate" dosages for various drugs are. All drugs need to be tested on people before it can be said they are "safe" for humans to use. All drugs also will at one point not have data suggesting they have sufficient efficacy.

There are also situations in which the ability for a particular drug to help a patient is speculative, but the patient's situation is sufficiently dire that it will be compassionate to allow the patient to "try" the drug.

I can say that if a cure is found, it will be fiercely opposed by the establishment. Covid has simply allowed for those in power to have too much control for them to allow for any effective treatments.

That explains why the establishment is so fiercely opposed to the vaccine because it must be even worse for their devious purposes than a cure, it prevents most people from even getting sick.
Vaccines will become less effective as additional strains inevitably evolve from the original virus. Vaccine mandates are one additional way for politicians to control people, and will be the means for them to assert additional control over citizens.

It is possible to see through some envelopes by holding it up to a light. There is also more advanced technology that can see through darker paper.

Tamper evident bags are really not intended to prevent an observer from looking at the contents inside the bag.

Agreed that envelopes and even thicker ones or darker ones may still be readable, but could you possibly insert another thick paper in there to make the original paper unreadable without opening the envelope? Or even insert small metal foil so no one can shine a light through? Your potential adversary would need advanced technology and I'd wonder if it may be worth it, or they would rather just open it anyway (and then you'll know someone opened it.)

You could have other forms of security to find out if the site has been tampered with or if anyone else has been to that location, depending on specifics. Cameras, or even other low tech solutions (hair stuck to the door, floor patterns of scattered rubble or whatever, dust?)
Sure, there is a lot you can do to try to ensure that you are aware of a compromise when you visit your offsite backup location.

The problem with the above is that it is generally unusual for someone to visit their offsite backup location, and that most people store all information needed to access coin in a single offsite location.

This will only result in negative outcomes. You will generally not know for a long time vis your tamper evident bag, they your backup has been compromised. There is also the potential that you will have multiple offsite locations compromised and you will not realize it. Or you might sacrifice physical security in favor of using a tamper evident bag that results in your private keys being stolen.

Regulation
Regulation is just a form of government control and should be minimized/moderated. I would not oppose a treatment just because it is not regulated. Similarly, if you are in a dire situation, you should be willing to accept experimental treatments to potentially result in a positive outcome.

I think we probably disagree on a lot of the above.
Typically, these drugs can only be consumed after receiving a prescription from a doctor.
True, but I just saw ivermectin being sold over the counter in a tractor/feed supply store.  Don't ask me why I was there, because I won't answer you (lol), but it's certainly readily available--and it's been hyped as a cure for COVID for quite a while now.  And believe me, drugs of all kinds make their way out of the supply chain all the time.  There are many, many ways that can happen.  Not to mention that any drug can be synthesized if you know a little bit about organic chemistry and have the right lab equipment.
I doubt that ivermectin is a cure for Covid (but I really don’t know).  I can say that if a cure is found, it will be fiercely opposed by the establishment. Covid has simply allowed for those in power to have too much control for them to allow for any effective treatments.
1208  Bitcoin / Hardware wallets / Re: [LIST] Bitcoin Seed Backup Tools on: September 17, 2021, 04:20:17 PM
Pretty cool concept. Obviously, if your entire seed is compromised, this will not do much good.
Not if you are using passphrase or multisig setup.
Your seed phrase can get compromised without you even knowing it if you don't have some tamper-evident solution like this.
Someone can find your seed phrase, copywrite your words and put your plate or paper in place like it was before, you would never notice it on time.

As I noted in my above post, you ultimately need to store all information required to access your coin, including any passphrase, and additional keys if using multisig. You can store this information in multiple places if you so choose.

If your security model includes storing portions of your seed in various offsite locations, a tamper-evident bag may provide minimal additional security. Like I mentioned above, these bags are typically transparent, so an adversary will likely not need to actually open the bag in order to see what is inside. It is also probably trivial to do things such as fold/unfold items inside the bag, as well as open things such as an envelope.
So I can use a non-transparent bag. Or put the seed phrase inside an envelope - either they open the envelope inside the bag, in which case it is obvious my seed phrase has been accessed, or they have to open the bag to replace the envelope, which gives the same result.
It is possible to see through some envelopes by holding it up to a light. There is also more advanced technology that can see through darker paper.

Tamper evident bags are really not intended to prevent an observer from looking at the contents inside the bag.

What substances are you referring to? Ivermectin? I looked back through his post history through the beginning of this month, and couldn't find any mention of any other substance that you might describe as "toxic and potentially fatal".
But no, I was talking more about when he tells people to drink bleach or chlorine dioxide, which he calls "MMS".
Chlorine Dioxide is sold on Amazon in tablet form that is intended to "purify" contaminated water. I have not seen any data regarding if Chlorine Dioxide will help prevent covid, but my guess is probably not. When used appropriately, in the correct quantities, I don't think Chlorine Dioxide is going to be fatal.

If you consume too much water (even if it is not "treated" with Chlorine Dioxide), there is the potential for fatal side effects. Ditto with oxygen. Both are also needed for humans to survive.
His recommendations of ivermectin, HCQ, suramin, and other pharmaceuticals are certainly not benign - all these drugs come with serious and potentially fatal side effects, and are not effective for any of the conditions he says they are.
Typically, these drugs can only be consumed after receiving a prescription from a doctor.

I understand that you are a medical doctor, although I am not sure what your speciality is, or if you work in a hospital or a private practice. I think there is a good chance that you have prescribed chemotherapy to one of your patients (or if not, some of those you attended medical school with you have). As I am sure you are aware, chemotherapy is effectively poisoning specific parts of a person's body with the hope that said poison will kill off cancer. The effects of chemo have the potential to kill patients who are receiving said treatment. Before starting chemotherapy, doctors will discuss with patients the risks and benefits of said treatment.

The same is generally true (or it should be) for other drugs, including those that are unproven and/or "unapproved" for particular uses.

Those bags are useless, and will provide zero protection.
They provide zero protection, but they are not useless.

Take the situation where you have a seed phrase backed up in one location and a passphrase backed up in another. If you notice that your seed phrase's tamper evident bag/seal/whatever has been broken, then you will know that an attacker has your seed phrase and may be attempting to brute force your passphrase, and you will move your coins immediately to a new wallet. Without a tamper evident bag, you would not have this knowledge. You will also now know that that particular back up location is not secure and you will stop using it, information you wouldn't otherwise have.

No single back up I have is enough to steal any coins from me, but I definitely still want to know if any single back up has been accessed by someone who isn't me.
You ultimately need to store your entire seed, including any passphrase in (an) offsite location(s). Otherwise, you risk losing access to your coin.

If your security model includes storing portions of your seed in various offsite locations, a tamper-evident bag may provide minimal additional security. Like I mentioned above, these bags are typically transparent, so an adversary will likely not need to actually open the bag in order to see what is inside. It is also probably trivial to do things such as fold/unfold items inside the bag, as well as open things such as an envelope.

I am also not sure how often most people access their off-site backup location. I think for a lot of people, this is fairly uncommon, especially if the location is far from their home.

The purpose of a tamper-evident bag is really to provide assurances that the content inside the bag has not changed. This is really not an important question when restoring from a backup.

Those bags are useless, and will provide zero protection.
They are not meant to offer any protection, they should just to tell you if the bag was opened or not, something like sealed envelope, when you break the seal you know that content inside was compromised.
As I mentioned above, it really tells you fi the contents inside a bag have changed.

I don't know if anyone is familiar with this, but I found one interesting project called entropy seal for tamper-evident packaging, it is a jar with particles for storing any sensitive physical goods.
I am not sure if they are selling it yet but it is interesting concept, one thing I don't like is that some phone app must be used for capturing and comparing image,
so I wonder what happens if app is dead or not supported in new phone...

For many people, a wildfire will mean that a location will be inaccessible for months at a time, and there is the risk that houses will be looted. The same is generally true for hurricanes/severe floods. A severe flood may also physically move a medium documenting a seed, and it may be difficult, if not impossible to locate the medium, even if it survives.
I think it depends a lot where you live. In my region, there is little to no risk of the events you mentioned. I'm still a big proponent of off-site backups.
But especially for those, it's nice to have a tamper evident seal, be it a steel wallet that offers this feature or just a paper wallet stored in a ShiftCrypto tamper evident seals for example.
Those bags are useless, and will provide zero protection.

First of all, someone with physical access to one of those bags could look at what is inside the bag to obtain the seed stored in written format.

More importantly, once someone has access to private keys belonging to a 3rd party that they have compromised, they are going to quickly move the coin being secured by said private keys. This means you will likely realize your private keys have been compromised when your coin has been moved via transaction(s) that you did not sign. Or, you might arrive to the location of your off-site backup, and find the tamper-evident bag very clearly opened, but upon inspection of the blockchain, will find your coin was moved a long time ago.

Side note to all of this but keep in mind a lot of "fireproof" safes are not.
If you search google / youtube for fireproof safe failure you can see a lot of them.

Most fire "proof" safes have a specific rating regarding the temperature they can protect against, the specific types of contents they can protect given a specific temperature, and the amount of time they can protect said contents at said temperature.

If your safe is rated for paper, but you have a USB drive inside the safe, there will be problems for all the contents inside your safe. Ditto if the safe is rated for 500 degrees, but the fire immediately outside the safe is 550 degrees.

1215  Other / Politics & Society / General Milley apparently committed treason on: September 15, 2021, 05:55:23 AM
According to a report, General Mark Milley committed treason when he allegedly informed China that he would inform them if the US was going to attack China prior to the November 2020 election.

The above was so bad for the United States that it could have resulted in a preemptive nuclear strike by China on US cities, and Trump, who was the democratically elected President at the time, would have been unable to respond.  

The above is so bad that even Mr. Vindman, who is an expert in undermining US Presidents he does not agree with politically, has called on Milley to resign if the reports are true.


Regardless of your opinion on the War on Terror, and the War in Afghanistan, I think it is difficult to argue that the way the exit from Afghanistan was handled was anything less than treason. There was the question as to which members of the Biden administration (besides Biden) had betrayed their country.

What do you think? Should Milley be subject to a court marshall? Should he be released from his military command?

The standard for treason is very high, so it is unlikely he will be found guilty of treason.

He posts, and makes arguments in ways that are different than most other people. He also has views that are not mainstream.

I am willing to bet that if he had views that conformed with how you think, you would be saying very different things about him. BADecker is not hurting anyone, nor is he disruptive. If you see a post of his that you disagree with, I would suggest that you refute what he is saying with a well reasoned argument.

If you engage in the above, an observer may still be able to draw a link between the inputs and outputs in the mixing service.
How so? Isn't this what the mixing service is made for? To remove links between inputs and outputs?
From the view of the blockchain, I'd expect a mixer that takes multiple inputs on multiple addresses and sends me back the total to like 2 different addresses, to do it in a way that no trace is visible.
No mixer is guaranteed to have no link between the deposit and withdrawal addresses. The link between input and output transactions has been broken for many mixers.

If you are consolidating your coin, the output from the mixer will ultimately be combined into a single address. You could have the mixer send you a single transaction to a single address, or you could have the mixer send you two (or more) transactions to two (or more) addresses. If you instruct the mixer to do the later, you would end up combining inputs from the two addresses anyway.
1218  Bitcoin / Bitcoin Technical Support / Re: [Sep 2021] Mempool empty! Use this opportunity to Consolidate your small inputs! on: September 13, 2021, 05:31:04 AM
If you have reused addresses, you have already negatively affected your privacy.
Not necessarily.
Imagine if you and I had a private deal and you gave me your address and I sent you 3 payments on 3 different occasions. As far as the rest of the world knows an arbitrary address received coins from 1 to 3 [sending] addresses but they don't know if that address belongs to you. Consolidating those 3 outputs doesn't change that either.
If you sent me three transactions to the same address, an observer would, at a minimum, know that I own the sum of the transaction amounts received from you.

If I asked you to send the transactions to unique, and unused addresses each time you were due to send me coin, an observer would only know that addresses "a", "b", and "c" had received a particular amount of coin. Depending on your privacy practices, an observer may, or may not know the coin was sent by the same person.

You are correct that consolidating three outputs all sent to the same address will not further reduce privacy, but that is because privacy has already been incrementally reduced via the address reuse.
1219  Bitcoin / Hardware wallets / Re: [LIST] Bitcoin Seed Backup Tools on: September 13, 2021, 05:19:10 AM
Given that, the only way to be safe is to be redundant. Everyone should be using at least two back ups in separate secure locations. Because I do this, I am unconcerned if I lose one back up due to fire, corrosion, or similar, and so I do not feel the need to use one of these metal devices. Laminated paper in an airtight and watertight container is good enough for me.
Having some kind of "steel" or fire/crush/water-resistant medium to store your seed is fun, but I am afraid these types of products will discourage people from having off-site backups, which is what really provides security that people will not lose access to their seed.

For many people, a wildfire will mean that a location will be inaccessible for months at a time, and there is the risk that houses will be looted. The same is generally true for hurricanes/severe floods. A severe flood may also physically move a medium documenting a seed, and it may be difficult, if not impossible to locate the medium, even if it survives.

IMO, it would probably be most appropriate for most people to keep a paper copy of their seed in a fire safe in their home. They should also keep a separate copy in at least one off-site location. If the area they live in has a particular high risk of flood and/or fire, the off-site location should be particularly far from their home, idealy inland.
1220  Bitcoin / Bitcoin Technical Support / Re: [Sep 2021] Mempool empty! Use this opportunity to Consolidate your small inputs! on: September 13, 2021, 04:27:23 AM
It does when the outputs being spent are coming from different addresses. But sometimes (due to address reuse) all the transaction outputs are from the same address, like when people keep receiving payments in one address.
If you have reused addresses, you have already negatively affected your privacy.

Doesn't consolidating hurt privacy? Maybe consolidate, then mix? What's your opinion on this?
Yes, one "cost" of consolidating unspent outputs is a reduction in privacy. This should be considered when deciding if you want to consolidate your unspent outputs. The value of privacy is not infinite.

I don't think consolidating unspent outputs and subsequently mixing the resulting coin would provide much privacy benefit. When you consolidate unspent outputs from two previously unconnected addresses, an observer would know that the two addresses likely belong to the same entity. Mixing your consolidated coin does not change this fact. If you want to maintain your privacy, you will need to move your unspent outputs through a mixer before you consolidate your unspent outputs, or you could send your coin to multiple deposit addresses to a mixer, and have the mixer send you a single output. If you engage in the above, an observer may still be able to draw a link between the inputs and outputs in the mixing service. You will also need to trust the mixing service to not log, nor intentionally leak information about their customers.
