    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

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

    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.

      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.

    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.
