Users on SN know that Bitcoin seed generation needs a good degree of randomness. However some ways of generating random numbers is far more random than others.
Some algorithmic techniques to generate random numbers aren't. They're actually deterministic and reproducible. These are often referred to as Pseudo Random Number Generators (PRNGs).
If one were to rely on such generation techniques, you might find your seed, or your security compromised.
Therefore, in the world of computer security and Bitcoin seed generation, one need to generate what's referred to as genuine randomness.
Some see the dangers of relying of generating non-random numbers and generate random numbers 'by hand'. For instance, some Bitcoiners buy 200 die to generate their seed by roll them all the die at once in order to generate it.
Some companies, and people, choose to think outside of the box - looking for chaos in our physical world in order to generate randomness.
The billion dollar cybersecurity firm Cloudflare.
Cloudflare like any company, have a backup plan. But this isn't backing up data, or power generators, but backup randomness generation.
If ever Cloudflare finds that their source of randomness is compromized. Their backup, has a very Frisco sort of twist about it - their backup partly involves monitoring a wall of lavalamps - in order to guarantee randomness.
Their 60s inspired randomness generator has been given a monicker - LavaRand.
Don't think that Cloudflare have lost the plot or are doing this merely as a publicity stunt. They're serious about this backup and know that the randomness that's generated is genuinely random. They're sure that the movement of the globby lava heated up to move by the lamp is so unpredictable, it's perfect to generate random data.
The lava lamps are constantly watched live by cameras before the numbers are crunched. As you can see, just like an avid Bitcoiner, they don't rely on just one source to rely on, they use 96 lava lamps to guarantee genuine randomness.
Cloudflare have yet to call upon their seemingly hippy-inspired, but actually clever way of generating random numbers as of yet; but it's ready and waiting for the call.
In the meantime, it's just a pretty talking point in their lobby.
