The random number they generated is 53.

[–] Rhaedas@fedia.io 19 points 2 weeks ago

Truly random. I would have never guessed that one.

[–] pdxfed@lemmy.world 9 points 2 weeks ago

Mine said 42. I guess the only thing left I'm wondering is what was the question?

[–] IphtashuFitz@lemmy.world 22 points 2 weeks ago (2 children)

What ever happened to Cloudflares wall of lava lamps?

[–] InnerScientist@lemmy.world 14 points 2 weeks ago

They don't have quantum in the name.

[–] drspod@lemmy.ml 21 points 2 weeks ago (2 children)

They've pissed so many billions of dollars into quantum computing, at least they're using it for something.

Did anyone tell them that you can use the noise in a semiconductor junction to produce truly random numbers too? You can buy one for a few pennies.

Isn't there a truly random generator based on Lava Lamps? Lol

But I think the issue is the rate at which you can get random numbers

[–] einkorn@feddit.org 6 points 2 weeks ago (1 children)

IIRC that's Cloudflares random number generator.

I think I saw the video about it here on lemmy within the past week

[–] rottingleaf@lemmy.world 5 points 2 weeks ago

It's probably not truly random, when two centuries from now people have descended a few more levels down. Just like their result

[–] Treczoks@lemmy.world 13 points 2 weeks ago

Having worked in the field and having seen my fair share of supposedly "true" random numbers, I would really like to see how they would proof this bold claim.

First one to hack the bitcoin blockchain wins

I'm crypto-neutral and quantum-skeptical but this seems like a legit threat.

The other major cryptos have moved to a proof-of-stake which is more centralized, but also more flexible. For example I can easily imagine ETH upgrading to post-quantum cryptography.

But Bitcoin is much less flexible. It has never evolved past proof-of-work. It's much harder for me to imagine a unified upgrade for post-quantum BTC.

I mean, your non-upgraded coins being worthless should be a pretty solid motivator.

*as random as any other method

[–] DancingBear@midwest.social 7 points 2 weeks ago

For a number to be truly random (assuming positive integers) wouldn’t it have to be anywhere between 1 and infinity? What good is a 20 million digit long integer? Or a 103 billion digit long integer?

What I mean is, is it possible to even have a truly random number within a set of rules, say 1-100?

I guess I already gave a rule by saying positive integers, I don’t know this is crazy!

But have you ever come up with a random number on weeeeeeeeed, mannnnn

literally every new discovery: exists

[–] AstroLightz@lemmy.world 5 points 2 weeks ago (2 children)

Is it truly random though? If in a specific point in time, the number generated is always the same, then that's not truly random.

Absolute true randomness would be a different result every time it is generated in that specific point in time.

A bit Sci-Fi and probably unrealistic opinion, but it does make me curious about how this kind of randomness could be implemented.

[–] ReallyActuallyFrankenstein 3 points 2 weeks ago

I mean, when you collapse that logic you're effectively saying random is the same thing as non-deterministic. But they're different things, because even if an infinitesimally exact moment in time may "always" produce the same result, because the arrow of time only points in one direction, no such deterministic result can ever be replicated, and if the result cannot be replicated, then what is the difference from random?

[–] FunnyUsername@lemmy.world 2 points 2 weeks ago

this is not a bad point but it also feels a bit like moving the goal posts
