The blockchain can work  within our solarsystem but the mining part world be on Earth+moon due to synching for the miners.

I do not think the system works if we go to further stars and solar systems.

The transmission delay is far too long.

the ten nearest stars are

 https://www.astronomy.com/science/explore-the-10-nearest-stars/


Proxima Centauri                                               4.25  light years
The Alpha siblings                                             4.35 light years
The runaway star Barnard’s Star                         6.0 light years
The next nearest star is the red dwarf Wolf 359    7.9 light years
Lalande 21185                                                   8.0 light years
Sirius A is                                                          8.6 light years

BL Ceti and UV Ceti binary                                  8.6 light years


so lets argue we figure out how to safely get clsoe to the speed of light in a space ship (I doubt this)

my guess is  we continually go faster thil we get close then we slow down to a more normal speed

So maybe we end up doing 40% which means travel to the closest star would be 10 years by ship

I doubt this happens unless there is better science and we can trick fuck the speed of light laws.

So just on the solar system using mars earth Venus and some moons could happen and BTC with earth+ moon mining could happen


anything else or further ETH and Solana look better
