Quantum computing won't matter in the 2020s, but it will take damn near a decade to quantum proof the network.

I figure if we wait until it's clear that a cryptographically relevant quantum computer is less than 5 years away, we're pretty screwed.

Better to start preparing too early than too late.

He's only certified to award PhDs for pleb slop.

Framework is such a nifty laptop.

You can swap out pretty much any compenent in a matter of minutes.

I upgraded my graphics card in 10 minutes and only had to remove 4 screws.

Any network. No human knows other than Satoshi, and no machine knows.

For a large part of high school and college, my dream was to become a math professor. I loved math, particularly discrete math, like combinatorics, probability and graph theory. There's something about solving, or even understanding a problem that you noodle over for days, usually at the end of many hours of frustration. There's something about developing intuition for certain concepts, seeing patterns that was really attractive.

But I didn't go. I've told myself in the past that it was because I didn't want to and that the life of a professor seemed too grueling and lonely, but if I'm honest, it's because my grades weren't good enough. I goofed off too much in college and coasted through a too many classes.

But looking back, it was a blessing to not have that option. Academia in general and grad school in particular suck. It's a difficult life of moving to where the jobs are, of debasing yourself to fit the mold of the powers that be, full of egos, red tape and politics. And the type of people that graduate PhD programs come out a particular way. You can see it in their eyes. It's like they've lost a bit of their soul.

Academia, like most fiat institutions has that effect on people. It's driven by a zero-sum game of status, where demand remains high despite the economic prospects getting worse and worse.

I bring this up because apparently, the Brown shooter was a grad student. And like many grad students, the system broke him. It's a reminder that as much as it would be nice to have a chance at high status professions like the ones offered in grad school, there's a lot of risk as well, particularly to your soul.

Back in 2019, I got to teach a graduate class at the University of Texas on Bitcoin. I hold no graduate degrees, so the only reason I got to do this was because a couple of the professors there recognized that I was an expert. Sometimes the road less traveled still takes you to where you wanted to go.

I'm still waiting for some prestigious institution to award me with an honorary Bitcoin PhD.

Citrea is a BitVM zero knowledge roll-up where all of the Ethereum VM computation happens on the Citrea network, which is a second layer on top of Bitcoin.

I hope you educate yourself further so that you don't make such ignorant statements in the future.

Is Nic Crater the hate child of Nic Carter and Matthew Kratter? 😅

I'm just happy we're finally back to arguing about actually interesting conundrums like quantum risks rather than retarded bullshit like spam. 😎

If something like my migration BIP activates then either Satoshi upgrades the locking scripts for their coins or they get frozen.

While my research suggests it should be possible to enable a recovery option for BIP32 wallets, there's no additional data available that JBOK wallets would be able to use to prove to the network that they aren't a quantum attacker.

Backwards compatibility with regard to forks is taken from the perspective of a node operator rather than a transactor, but yes. Perhaps a new term is necessary.

I like huge OP_RETURNs

they reduce both blockchain and UTXO set data growth rates.

Why is it so fucking difficult to obtain pure, uncut, white cranberry juice?

Betteridge's Law of Headlines states that any headline ending in a question mark can be answered with "no." This suggests that if a publisher were confident in a positive answer, they would have stated it as a fact rather than posing it as a question.

Set up a new gaming PC with Windows 11.

Fuck Microsoft for trying to force you to have an online account tied to your operating system. And fuck their insane captcha system that I wasted half an hour trying to appease.

Eventually I got frustrated enough that I searched for the command line hack to disable the online registration requirement.

Andreas is more of a Bitcoiner than you can ever hope to be.

He has educated more Bitcoiners than your faux university will ever reach.

I love the smell of government shutdown in the morning.

We're so early that folks think Bitcoin is this level of odd.

That's the neat part, there isn't! Well, for larger than about 143 bytes IIRC. Bigger than that and it's cheaper to do witness stuffing.

If the Brits try to invade the US over this then you're goddamned right I'll be using my guns.

The proof of work contact form on my web site has a difficulty adjustment. I can it the annoyance adjustment. Any time I start getting annoyed by the volume of messages I receive, I bump up the difficulty.

I started off 5 years ago at about 30 seconds worth of hashes on a desktop CPU and now am up to 10 minutes.

Overhead: the Kelce-Swift engagement is like 9/11 for every guy in a long term relationship who hasn't proposed.

There is no amount of anger, crying, or virtue signaling that will defeat information theory. Accept it and move on.

You chose to create news rather than report news. Understandable given the incentive to drive attention, but not really a best practice for journalism.

More specifically, you chose to interpret Google's (admittedly poorly worded) policy without actually doing the legwork of asking them first. Next, your article claimed self custody apps were being banned while providing zero actual examples.

As a self custody app publisher who pushes builds every few days, Casa is keenly aware of policy changes and we knew that no such interpretation was being applied upon us.

Your fearmongering caused some of our clients to freak out and flood our support team, questioning if Casa's app was going to abruptly disappear.

It's commendable that you got Google to clarify their policy. But I dare say it could have been achieved without the stress and drama.
