So essentially instead of hash-based computer proof of work, you're suggesting looking at cloud patterns (say, as the sun's proof of work)? Sounds like a great way to save energy, if we can ensure image authenticity/integrity.
- dreamcompiler 8y agoThe vulnerability is the one satellite everybody is looking at. But that could be mitigated by having a network of ground stations looking up and asking "is it cloudy overhead?" With enough of these sample points scattered around the planet and correlated with the satellite's imagery, one could make hacking the satellite impractical.
- atoav 8y agoWhy not taking the clouds of Jupiter? Then you could use telescopes and multiple satellites alike because that far away parallax shouldn’t change a lot.
- dreamcompiler 8y agoJupiter's not always visible from Earth (sometimes it's behind the Sun). Earth is always visible from a geo sat (provided the satellite is working).
- atoav 8y agoLet's use the sun then :)
