Okay, not the stars, but the planets. Mars, at least, it’s the closest one. I was thinking out loud on twitter about how to handle bitcoin when we become a multiplanetary species.

I just realised that bitcoin doesn’t work when we become a multiplanetary species. Takes too long to sync. Mars is relatively close half the time of the year.

Closest possible approach: 182 seconds, or 3.03 minutes

Closest recorded approach: 187 seconds, or 3.11 minutes

Farthest approach: 1,342 seconds, or 22.4 minutes

On average: 751 seconds, or just over 12.5 minutes

We might either change the protocol to deliver slower blocks,

Which would suck for us. Or simply use a relay at a shorter distance, resting at a Lagrange point. Others are too far away. Titan is far out. Light from the Sun takes about 80 minutes to reach Titan; because of the distance. So that means Titan and faraway colonies would need their own bitcoin chain to run. A theoretical technology is entangled particles for faster than light communication, but nobody knows if it’s possible or even practical. The small blocks might be a blessing for that. We’ll cross that Einstein-Rosen bridge when we get to it.

Someone pointed out to me these series of articles on the subject, great resource. https://unchained-capital.com/blog/law-of-hash-horizons/

I’ll think about it further, might end up in my novel.
