Is this periodic password change recommended to increase the security of our account?
If you do not reuse your password and your password is not a derivative of other passwords you use on other sites, you should not need to change your password unless it becomes compromised. I would recommend using a password manager to generate and secure your passwords.

If so, are there any issue users might face if they periodically change their account password every years?
If you change your password, you are risking that you forget or otherwise lose access to your password.

Changing your password, AND using unique passwords, AND not using a password manager means that you will generally use less complex passwords, which will make your accounts more vulnerable to hacking attempts.

His testimony <> speculates that Chauvin used 90 pounds and exerted it onto Floyd's neck. Dr. Tobin openly admits he used a still picture to arrive at this figure. Obviously I don't need to explain why this has all sorts of issues.

The defense should have objected to this answer. The same is true for any conclusions Dr. Tobin made. I expect Chauvin to mount a defense that includes their own expert witnesses.

I would not do this. My advice is to move your bitcoin to an exchange (if you intend on selling them), or a new wallet (if you plan on holding them), then to download the wallet software on a fresh device for each fork you are claiming.

I think there are only two situations when some trust is involved. The first one is when you have milisatoshis and you really care about them. As long as the channel is open, you can spend them. The other one is when your node goes offline for some reason which means that the other party can broadcast an old commitment transaction. You can freely set the amount of time which the other party must wait before the transaction can be included in a block after it was broadcast. Most nodes will accept timelocks up to 2046 blocks (~2 weeks), so it shouldn't be really a problem. I could mention watchtowers here, but they are obviously a third-party.
I would add a situation to your list. If your channel at one point had inbound capacity, and you currently have zero, or very little inbound capacity. The cost of a peer to attempt to get an old channel state confirmed is zero. In some cases, the cost to broadcast the "penalty" transaction may be higher than the amount being stolen from your channel, if transaction fees are persistently high.

You could also set up watchtowers that are controlled by you but are separate from your LN node.

@5:17, the Lt. openly admits the knee is not on the back of the neck, but rather the shoulder blade. And that is completely allowed by MPD policy according to the Lt. to gain control.
This is a very major point. The video that went viral last summer appeared to show Chauvin's knee on Floyd's neck the entire time. I think it is a scandal that photos of Chauvin's knee on Floyd's shoulder and/or back are just coming out now. The defense should make a point to determine just how long Chauvin's knee was on Floyd's neck.

And just a quick point on the homicide aspect of this. Homicide is not murder. If Floyd died because of the stress of the situation on his heart, something that would not normally kill but for drugs in his system, that isn't the officer's fault. Homicide here means but for the actions of the officers, Floyd would be alive. Meaning had not police been called to the scene, Floyd's heart rate would not have skyrocketed, therefore he would not have died. That's all homicide means. That doesn't mean drugs were not the main contributing factor of death, or the deciding factor of death.
Chauvin is charged with three crimes, 2nd-degree unintentional murder, 3rd-degree murder, and 2nd-degree manslaughter.

The 2nd-degree murder statute says in essence that Chauvin was committing a felony, did something that killed Floyd involving force or violence, and did not intend to kill Floyd. IMO, this is a stretch, even in the most favorable light for the prosecution and the prosecution will have to prove both that Chauvin's actions caused Floyd's death, and that Chauvin committed a second felony while doing so.

The 3rd-degree murder statute says that Chauvin did something dangerous without considering Floyd's life that killed Floyd. I would say there might be probable cause for this charge. The knee on Floyd's neck is reasonably dangerous, but the legality of this would be a point of contention. Also, if Chauvin's actions actually killed Floyd is another point of contention.

The 2nd-degree manslaughter statute says that Chauvin was neglect in creating an unreasonable risk to Floyd's life and took the chance of causing Floyd's death and that Chauvin caused Floyd's death. This is a very similar standard to the 3rd-degree murder charge, and the Jury will likely return the same verdict on both counts.

--NFTs are awesome--
If someone sells a "NFT" of say, the Monalisa, under what authority is the painting sold digitally? What would stop a random person, who has no connection to ownership of the actual Monalisa from selling this NFT? If there is already a NFT of an image in existence, what would stop someone from changing a small number of pixels of said image, and selling a NFT of said image?

There is also the issue of GANs. Someone could potentially create a GAN whose generator network creates images of art. Once the GAN is created, it would be trivial to create a near unlimited supply of NFTs.

Last summer, millions of Americans were receiving more in unemployment than they were receiving while working and didn't have to pay for expenses related to work such as gas for commuting, dry cleaning, or eating out to lunch. Americans have also received thousands of "stimulus" dollars, while many traditional forms of entertainment are closed. I think the crazy prices of NFTs are largely a result of this excess money given to Americans.

Yes, you're wrong. The people you shouldn't trust are those who start from one position, and then stick to it relentlessly, even when evidence piles up to confirm that their position is incorrect.


Fauci has stated that he did not change his position on topics because he had additional information. He has stated he changed positions because he had previously known his position was incorrect at the time, but publically said things contrary to his beliefs for reasons relation to social control.
1708  Other / Politics & Society / Re: Riots after Death of Man in Minneapolis Police Custody on: April 04, 2021, 09:01:13 AM
If the procedure is to give priority to other threats, the defense argument would be that Chauvin was following procedures, and I think that is a pretty strong argument.

See, my issue here is that Chauvin probably was thinking about this to an extent so you're not wrong, but to me it's just tough for optics that the restraint was held and chest compressions weren't started. If the argument is that the crowd was angry and that diverted Chauvin's attention, then it surely seems like the paramedics were in the same mindset because they did a load and go, meaning they did not render aid right there on scene. They drove 3 blocks.

If the situation was as dire as the paramedics testified, shouldn't they have utilized all the resources they had on the scene instead of driving away 3 blocks which took away valuable time? So there's truth to your statement, but I just don't think the average person is going to think about that, so they'll listen to the sgt. who testified the knee should've come off.
I didn't watch the trial live or otherwise, and I was not able to find any article talking about the ambulance driving away for 3 blocks. The articles I read say that the initial call was a "code 2" which means the ambulance did not use lights/sirens (it wasn't an "emergency"), but was later upgraded to a "code 3" which means lights/sirens were used (it was an "emergency").

Chauvin has long ago lost in the court of public opinion, and regardless of the outcome of the trial, will never work again. The same is probably true for his (ex)wife and his (ex)wife's kids. What the public thinks does not matter in a court of law. Ultimately if Chauvin was following procedures, he should be found not guilty under the eyes of the law.

Last witness was current Lt. for the MPD. Suffice it to say, he was devastating for the defense today. Openly stated that the knee was too much force, should not have been held for as long as it did because it can kill, and that once Floyd was no longer resisting, it should have came up. Really tough for Eric Nelson to navigate out of that, and he wasn't really successful during the cross examination.
Again, this really comes down to procedures. A Lutentiant for the PD is not going to have the medical expertise to know that putting a knee on a suspect's neck is "too much" or that it "can kill", and this should not have been allowed by the judge. The fact that this was allowed into testimony is probably grounds for a successful appeal by Chauvin for either ineffective counsel, or the judge allowing prejudiced testimony from an unqualified witness.

Even if the use of force was "too much", it boils down to if the excessive use of force was a contributing factor in Floyd's death.

Then here we’ll have another governance problem, another stalemate. What if the economic majority/community/users/developers want an upgrade, but the miners hold the network hostage by not signalling for the upgrade? I believe the UASF proved that miners follow the full nodes that which creates a specific demand for the miner’s “product”. Blocks.

I would view a USAF change as contentious, and contentious changes should be avoided when possible.


Then which fork currently is the real Bitcoin? Definitely not the one with Segwit if you believe UASF was “contentious”.

SegWit was implemented after the miners agreed to the upgrade. A USAF upgrade was threatened, but this threat was never carried out. Read the article you posted, especially the last several paragraphs.


The UASF was starting to pick up, with some developers, and exchanges beginning to support it, that’s why the miners only started to agree with the update. Without UASF, they would have continued to hold the network hostage.
This is speculation. What ultimately matters is the economic supermajority.



Quote from: PN7


I think it is best to attempt to get the miners to agree to an upgrade first, and depending on the feedback the miners give, a USAF change can be considered if the miners do not agree to a change. There is a big difference between a single miner with 10% of the network hashrate opposing a BIP, and a single pool with 5% of the network hashrate in favor of implementing a BIP. If it is the former, this is probably a miner holding the network hostage as you describe, and a USAF should be considered, while this is probably not the case for the latter.

It is very easy to fake economic activity and nodes. It is also difficult to tell if two people claiming to be two different people on the internet are actually two different people. What cannot be faked are found blocks. As I mentioned before, the miners have long-term incentives aligned with that of the long-term health of bitcoin.


OK, before the developers propose something to improve upon the protocol, they should meet with the miners first to see if they agree, then post it in the Bitcoin Mailing List, IRC, and the forum?


BIPs should be implemented the same way they are implemented now. Once a BIP is agreed upon and put into the codebase by the devs, the miners should signal support or opposition to a BIP via their found blocks.


What if the miners hold the network hostage again by not signalling readiness for an upgrade the community wants?
I previously discussed this possibility. If a BIP is not receiving support from the miners, the community could consider implementing a USAF, while taking into consideration the amount of support the miners gave. As I mentioned before, there is a difference between a small minority of miners supporting a BIP and a miner basically using veto power to oppose a BIP. The community should also consider alternatives to a USAF, such as lowering the activation threshold or modifying the BIP in a way that makes the miners more comfortable.

As I previously stated, the miners are the only entity that cannot fake their level of support. It is trivial to run an arbitrary number of fakes nodes, it is trivial to create an arbitrary number of online personas, and it is trivial to send many transactions to yourself to make it appear your business has a lot of economic activity, when your business does not have any customers.
1710  Other / Beginners & Help / Re: You need discipline to be successful in trade on: April 03, 2021, 07:51:15 AM
For example, professional gamblers also have that, extreme level of discipline. I worked for years in casino, and I am sure of only one guy who was regularly taking the money out of casino. He only played slot machines and he had strict rules that he followed no matter how much he won, with set limit of money he afford to loose every day. The only reason he didn't get banned from there is that he was not gambling big. But he was happy taking every month few hundreds of dollars.
Any gambler who "regularly" wins at a casino is cheating. Period.

All casino games are set up in a way, such that, over the long run, the gambler will lose. This has nothing to do with being "disciplined", it has to do with the fact that slot machines are designed to payout less than $1 for every $1 gambled over the long run.

More important than "discipline" in trading, is the importance of using data-driven decisions when making or exiting a trade, rather than using one's intuition. You should use a model or indicator that says to buy or sell, rather than "I believe in x coin" or "I think x coin will go up/down"

even if Phoenix/Breez etc begin to use these new cheaper dual-funded channels (which is also a lighter burden on the blockchain & utxo set...), they will still presumably charge a small premium to do so. Some people won't want to pay that.
At the moment, Phoenix is cheaper to fund than creating my own challel, and doesn't reduce the amount I can spend for a channel reserve either. I can't imagine this is sustainable as a business model, so if they change it, I might change my wallet too.
Phoenix has a well-connected node. They are basically forcing you to route your LN transactions through their nodes, so they receive the routing fees, and are also receiving the portion of the transaction fee that is a % of the transaction amount. Since all transactions must go through their channels, they control the fees that are paid both by you and by anyone who sends a payment to you.
1714  Other / Politics & Society / Re: Riots after Death of Man in Minneapolis Police Custody on: April 02, 2021, 04:26:42 AM

Could you say that Chauvin was negligent because he did not do chest compressions? Yes, I think you could. Is it important to consider outside factors? Sure -- you look at the fact that they called for code 3 response, which means stepping up paramedics and getting them to the scene ASAP. So medical care was inbound. You also have to take into account an aggressive crowd and what role that had in diverting any attention of the officers. The defense made the argument when questioning one of the witnesses, a former police sgt. on Chauvin's shift, that other threats/dangers have a higher priority than providing medical aid. Not the greatest argument, again, but we all knew this would be the hardest hump to get over for the defense.
If the procedure is to give priority to other threats, the defense argument would be that Chauvin was following procedures, and I think that is a pretty strong argument.

Also, on the day 2 video you posted, several minutes after the 6(hour):49(minute) part you mentioned, the EMT (who was off duty at the time) talked about "tunnel vision", which is something I think would favor the defense regarding why chest compressions had not started by Chauvin.


To investigators, Ross told them that Floyd had a foamy white substance running from his mouth as she took him to the hospital during Floyd's drug overdose. Floyd also had a foamy white substance running from his mouth during his May 25th arrest, confirmed by multiple witnesses. This is a huge fact that no one knew prior to today, and of course, the defense capitalized.
This supports the defense argument that Floyd died from a drug OD.

Login by using signature.

Signing in would change forever! This could be maybe one day a thing of the internet future.

Users register a one time wallet address on their profile account.

Random message generated for each time a user logs in which has to be signed by the private key 🔑 , user have to provide the hash using a submit window, backend checks the hash and if the hash is correct for that specific address then he is logged in.

This is not a novel concept. This is basically what google authenticator does, except it uses the current time instead of a random message, and generates a numerical code instead of a signature.

I also believe what you are calling for was specifically implemented in one or more of the darknet market sites that eventually got taken down, at least IIRC.

The only logical choice is to continually roll for random user fNFTs until you get a satoshi one

It is possible to get satoshi, but the probability is only about 0.03% per roll, so someone will have to get awfully lucky.
I don't think this is right. Satoshi's NFTs are not listed for sale. Unless buying a random NFT will allow you to get a NFT not listed for sale?

It also doesn't look like satoshi actually has any NFTs. This is surprising considering how much coin he mined in bitcoin's early days.

I don't think such thing is needed. I'm not sure how safe it would be looking from security perspective.
When you enter your password before you click "login", the password is stored in RAM locally. The only potential security implication is someone may see the text on the screen, but users will be aware of this before clicking a button to display the typed password.

It is generally best to use some kind of password manager to avoid reusing passwords and to easily save and keep track fo each of your passwords.
1718  Economy / Service Discussion / Re: Proposal for a new Bitcoin Mixing technique on: March 31, 2021, 05:46:46 AM
I've boiled this down further, I think -- a more concise explanation, for reference:

  • Alice wants to Pay Bob 0.5 BTC
  • Alice sends 0.2 BTC to Deposit Address A, followed later by 0.3 BTC to Deposit Address B
  • Coin Z (0.5 BTC), somewhere else, is sent to Bob and is entirely unconnected to Alice's deposits

More, and most importantly:

  • Coin Z went through 200+ separate CoinJoins over a period of 6 months
  • The Coin Alice Deposited at Address A, later on that day participates in a CoinJoin
  • The Coin Alice Deposited at Address B, participates in a separate CoinJoin 2 days later
  • Alice's Coins are CoinJoined 20 or even 200 times before they even make their way back out of the mixer
In this scenario, it is very obvious that coin Z is from a mixer, and analysis can be done accordingly. It is also obvious that Alice's two deposits are going into the mixer.

The delaying of starting CJ transactions does nothing because there is a pattern of going directly from the deposit address into CJ transactions, and it would be obvious that both deposit address A and deposit address B received coin that went into the mixer on the same day.

Most mixers have known addresses and clusters to blockchain analysts, but someone studying a mixer may not know about all of the addresses belonging to a mixing service.

If I knew nothing about this case and used just the testimony from today's presentation by both the prosecution and the defense, I would undoubtedly be leaning towards a "guilty" verdict. But obviously, this is the first day.
I think the jurors will feel compelled to bring a guilty verdict, even if the prosecution doesn't present any evidence. Some probably fear for their family's safety. I don't doubt that left-wing media outlets have already doxed some of the jurors, and may have contacted them/their family for comment.

I would expect nationwide riots with a not-guilty verdict.

Eric Nelson asked all the jurors about this concern during jury selection about whether they feared for their safety and were inclined to vote one way or another. Everyone that was selected said no so I'm actually not too worried about this.
I am not sure if anything about the aftermath of Floyd's death will be allowed, but if so, the jurors will likely change their minds.

But, if they get doxed and harassed/threatened I wonder what happens then? An alternate comes in?
There might be alternates that are not part of the jury, but sit with the jury, and hears all the testimony and arguments. In the event that one of the jurors is dismissed, the alternate will take their place. If more jurors than alternates get dismissed, there will likely be a mistrial. I think if anyone were to contact any of the jurors, a mistrial would probably be declared.

Anyway, you have 12 jurors total and the prosecution needs 12 people all to vote guilty. That's already feels like an uphill battle because how are you gonna get 12 people to agree on this case that is so controversial with so much grey area?
You could say the same thing about an aquittial. If there is a hung jury, the prosecution would try again.

I think the jurors will feel compelled to bring a guilty verdict, even if the prosecution doesn't present any evidence.

I wouldn't worry about the prosecution not presenting any evidence.  Pretty sure they'll play the video of the cop kneeling on the guys neck while he begged for his life then died and then show them the autopsy reports that concluded it was a homicide.
Will they leave out the part about Floyd saying he can't breathe before he was on the ground? The same plea he was making while he was on the ground? Will they leave out the part about that Floyd had lethal amounts of illegal drugs in his system when he died? Will they leave out the part about how the medical examiner said that if he had not seen the video of Floyd dying, he would have thought Floyd died from a drug OD?



Problem is, quite literally none of these witnesses were objective in nature to what they observed, but added a lot of additional commentary and speculation.
This should have been objected to by the defense counsel, and not allowed to be entered into the record by the judge. If the defense counsel did not object, there may be a case for ineffective counsel if he is found guilty.
