Stumbling around

The main design weakness that I perceive in Bitcoin is its reliance on the hardness of SHA-256 for the entire accumulated Proof-of-Work. If someone were to break SHA-256, the entire 14 years of Proof-of-Work would become invalid all at once. And that PoW is what protects the entire ledger, so to avoid having the whole ledger rewritten, Bitcoin would probably have to use a kind of "official snapshot" to preserve the original transaction history, which seems awful.

In my opinion, there should be multiple hashing algorithms interleaved, so that if one is broken, the Proof-of-Work chain largely remains standing while replacement algos are added.

The responses that I've received to this, is that I don't know how the cryptography field works (which is true) and that SHA-256 can't be broken just like that - that "we would know" because such hash functions don't get broken in one step, but weaknesses are revealed over time. I doubt this - we would know if an *academic* finds weaknesses because they would publish to get famous, but if a government breaks it, how would we get advance knowledge of it?

The Great Pyramid's conspicuous speed of light latitude is no accident

https://www.researchgate.net/publication/306097887

"The Great Pyramid was built ∼4500 years ago but a neighbouring monument exhibits considerably greater signs of ageing. Sea levels were appreciably lower at the end of the Ice Age when Giza was situated at the intersection of the lengthiest geodesic and parallel over land, a record the carving of the Sphinx appears to have commemorated. The Sphinx patiently weathered a hostile climate until the Great Pyramid was constructed, whose latitude in degrees tallies with the speed of light, c = 299, 792 km/s, to six significant digits. The pyramid's geometry showcases both π and the golden ratio, φ, with the conjunction π − φ^2 ≈ π/6 ≈ φ^2/5 not only providing a natural basis for the cubit/metre ratio but also approximating the speed-of-light latitude in radians. Its scaling reflects the size of the Earth and its rotation rate. By relating cubits to metres and days to seconds, this mighty monument quite deliberately encodes the value of c, figuratively permitting the conversion of energy to mass. Parallels exist with a recent analysis of Avebury, which also demonstrates ancient knowledge of modern physics."

At first I thought the "speed of light latitude" was nonsense, because the meter was only defined at the end of the 18th century, but I learned that it was defined as a ten-millionth of the distance from the pole to the equator, which is not completely arbitrary, so it's not impossible that the Egyptians used the same unit (up to a power of 10). Somehow the paper implicitly assumes that their unit of angle was the degree; ok could be, from what I read the Babylonians also divided the ecliptic into 360 degrees.

However, the paper doesn't take into account the fact that the African tectonic plate moves northeast by about 2.15 cm per year. This would mean that the Great Pyramid has moved north roughly 70 m since its construction ~4600 years ago, so its original latitude was probably about 29.9785 degrees, no longer quite such an uncanny match with the speed of light.

I am not clear on how these four groups are affected by the new rules:

- iPhone users in China

- iPhone users outside of China

- App developers in China

- App developers outside of China

In #Bitcoin, the sum of mining rewards over 4 years is the same as the sum of all mining rewards ever after. Think about that...

I'm not big on conspiracy theories, but I've got to admit this is almost a cartoon: two objections to Coleman Hughes' TED talk were placed by a Federal Reserve program director, and by Adam Grant who is a WEF "young global leader" according to his university profile:

Maybe both can be combined into a single desktop client with two "modes". When you're in read-only, you'll come across something that you want to respond to, and it would be annoying to switch and find that post in a separate client

I also read about those ordered hits, apparently he got scammed by someone impersonating a gang of thugs for hire. But besides that, he took a significant cut of the >$180M worth of illegal drugs trafficked on the platform. His sentence may be harsh (and indeed many others who should be investigated/prosecuted remain protected through layers of corruption), but the "innocent eagle scout who just built a website" story is pretty disingenuous imo

I wish we had a better book than the bitcoin standard

Yep looks like UTXO consolidations, here is the flow of one of them:

is there a record of how long they've been in the mempool?

It was even well studied by ExxonMobil scientists who were financially incentivised to keep it quiet, in the 1970s and 80s, well before this became a popular narrative.

You didn't say which of the three points you thought was scientifically the weakest.
