No lol hard forked off chains can not merge back together like some liquid thing. The chain is a block per block proof of work tie. A merkle tree. You can not shove an entry in the middle of a merkle tree, you would change the hashes of the entries that come after it.
So it is not secure to do what you're suggesting. You would have no sense of final settlement and people would get their transactions reversed all the time.
I think you should re-read what i wrote. I specifically avoided mentioning merging forks. I'm talking about off chain transactions that are eventually settled on chain which are happening now. In the context of far distances in space, they would also eventually be settled, but much much slower, in relative terms.

Okay, I misunderstood, "It would be like a community breaking off from the internet at block 800 000, never changing the code and the coming back at block 900 000."
Ignoring the fact that you can't do this with drivechain specifically, it would have to be some other sidechain method, but are you really expecting people to mine these sidechains all across space and not try to also mine the main chain? Earth, with its limited access to electricity to power ASICs, would have to compete with who the hell knows what probably some miner that's set up shop next to a blue giant. Do you understand how huge that re-org would be? I don't mind the idea of fractal off-chain solutions that eventually scale to serve the community of trade it needs to serve, but the base chain needs to be the slowest chain.

Ignoring for the moment that i am suggesting a slowed peg, and that that is exactly what drivechain a can do...
but are you really expecting people to mine these sidechains all across space and not try to also mine the main chain?
I would if both distance and incentive are at play. A galactic economy based on earth at its core and earth bitcoin, would have to eventually settle in earth bitcoin, but local currencies, colored coins, fiat IDGF would be more available . Bitcoin as final settlement. God can you imagine the fees.
Even if the distant miners were to try and mine bitcoin and somehow use an excess of cheap energy over there to profit here, the distances already exclude any excess amount of energy far from earth from competing with earths miners.
Put another way, c means there is a cost to transporting that information back to the earth. That miner has to expend energy to escape the blue giants gravity well, then travel to us, all before we have significatly upgraded our own miners in the time it takes them to get here. Space-time arbitrage might happen, but not fast enough to cause insecurity in the main chain.
Actually that is an extremely interesting attack vector. If our entire civ was based on expesive energy and someone started broadcasting cheap energy bitcoins it would kill the economy. lol
This is all assuming sub FTL obviously.
