What’s up today? (Part 2)

Hardware wallets are mainly used for 2 reasons - they have a heat-generating chip from which true randomness is extracted to generate the private key, which makes it impossible to break it out, unlike private keys generated with a program on a computer and stored on a flash drive.

The second reason is that the hardware wallet’s private key never leaves it, when you connect it to a computer and make a transaction, you send it to the hardware wallet for processing and in return you only get the signed transaction. In the PC flash drive variant, the private key touches the vulnerable operating system.

Thanks for the explanation Interesting, those are valid points to consider.

You can use an old device without any connection, to sign the transactions.
And you can move transactions between offline and online devices via QR or USB.

This way the private key never touches the internet.

Yes, but this does not eliminate the danger of generating a private key with a program without physical randomness (of course you can use a dice to generate it), such as you get from the specialized chip of the hardware wallet extracting it from heat.

Plus, as I said, these are the main reasons, there are others, such as the possibility of putting the hardware wallet in a bank safe, which I personally practice. Of course, you can also put the private key (seed phrase) itself on paper in the safe, but in unencrypted form anyone will be able to use it, while the hardware wallet is protected by a pin code and an additional word to the seed phrase.

Overall, for 99.99% of people, for convenience/necessary knowledge to stay safe, a hardware wallet is the right choice and worth the price.

Not true. On Linux anyway, the “haveged” package is available to maintain a large pool of randomness for use by password managers. Learn more about it here:

As I said, even with dice you can get such randomness, the question is whether the end user has the knowledge to do it and then operate correctly with the private key. Because if the end user doesn’t have it and chooses the wrong private key generator and made a mistake in practical use, he could end up without money:

What is more likely to happen?

That the generation of a 256-bit key is so badly done that someone can find it?

Or that it leaks out that you have a device for storing cryptos which would allow criminals to break into your home, and threaten or torture you until you hand them over.

Personally I see the second as being far more likely than the first.

There are cases of hardware being physically seized and I’ve heard of 4-5 in the last 10 years, but as a percentage of the total amount of crypto lost it’s negligible.

You are more likely to lose it due to Phishing Attacks, Malware and Keyloggers, Weak Security Practices, Exploits and Vulnerabilities and Social Engineering.

Some of these vulnerabilities can be protected with a hardware wallet. But of course everyone should assess the risk for themselves.

not when such leaks have already occurred, and database of names/addresses are available for sale, or possibly even free on darkweb.

Of all the super-volcano’s in the world, the Campi Flegrei caldera in southern Italy is the most likely to erupt within our lifetimes.

While it would affect the whole world, Europeans need to pay particular attention.

More detail on the ruling that immutable smart contracts in the Tornado Cash case are not a service and so cannot be sanctioned by authorities.

Could be an interesting precedent for anyone building an autonomous network of immutable data:

Worth reading Molly’s thread for the definition they used for a service which amounts to immutable → no human labour → cannot be owned → cannot be a service.

Whether that protects the network builders I don’t know, but it might. Node runners, not, I think.

Didn’t they arrest one or more of the tornado cash devs? Anyone know the status of that? Or did I imagine that news?

nope, you didnt imagine it.

How do those affected feel about this? Harmful chemicals being added to cow feed to stop them farting :rage:

For years people have been wringing their hands about cattle methane emissions. As usual, for the wrong reasons.

What they generally don’t talk about is that cattle eating their natural food (grasses) don’t fart any more than any other animal.

The bulk of the methane is being produced in giant feedlots where thousands or tens of thousands cows are kept in insanely overcrowded conditions. They walk in bare dirt/mud covered with manure and not a single blade of grass. They are fed corn, molasses and other supplements intended to (a) fatten them up quickly and (b) soften their muscle (meat). This unnatural diet of course produces flatulence.

It also produces disease. Tissue breakdown, which brings bacteria to remediate. So then the feedlot operators pump the cattle full of antibiotics to suppress the infections until the cattle are butchered. This also happens with chicken, pigs, etc, and it is why better (non factory-farmed) products now proudly proclaim “no anti-biotics ever”.

In California’s central valley there are numerous of these feedlots and motorists passing by on Highway 5 can smell them for miles approaching. Its that bad, and everyone knows it.

So basically we humans force cattle into unnatural conditions, feed them a horrible diet, deprive them of exercise, and then complain that they fart.

Apparently the next step is to add even more poisons (propylene glycol is anti-freeze) into their diet to prevent the farting, which probably will be inducing more cancers, etc. And yes, is being passed on to humans in the meat and milk.

The whole thing is insanity.

And that’s just the USA beef industry. The dairy industry is probably worse. The poor calves that are taken from their mothers at birth and often die. The mothers that are grieving the calves and the emotional stress adds toxins to their milk due to mammary tissue breakdown and bacterial remediation, a possible source of TB (my theory). Also overcrowded conditions in huge operations ever since the family dairies were paid ~$100,000 each by US gov to get out of the business in the 80s.

For my part, my family eats much less meat than we used to, and only grass-fed, to avoid the entire feedlot mess. We no longer buy milk, except every once in a while some raw milk from a local dairy. We buy european (usually french) butter, or have sometimes made if ourselves from raw milk cream.
