In “Stellar Lavarand,” Ben Laurie writes:
Some crazy people think they can make a business of this, only using the solar wind, the clouds of Venus, the Northern Lights, Jupiter’s shortwave emissions and other cosmic events as their random source.
Just like lavarand, this causes a moment of “oooo, shiny”, rapidly followed by “but why would I want someone else to see my randomness?”. So, kids, feel free to point and laugh at anyone foolish enough to use this service for anything real, but don’t try it at home.
I can imagine a number of protocols that rely on a source of random bits that both Alice and Bob get at the same time, and which can be independently verified to have been outside the control of a third party.
Is it a business? Seems doubtful, but it’s interesting that it’s being tried. Who knows what might emerge?
