Mars can use Lightning Community for intra-Mars transfers and not using a drawback (though some safety ensures may weaken as a result of delay on opening/closing channel). I believe routing LN-payments between Earth and Mars is feasible as properly (even for side-chain case I current under).
Transferring on-chain could be slower they usually’d possible should both
-
depend on Earth’s full nodes with a view to keep away from partitioning (gossiping transactions between Earth and Mars mempools might be problematic as a result of delay). All mining could be on Earth then.
-
Mars constructing their very own side-chain with their very own community and miners (the way in which RSK and others work) – all interactions with Earth’s chain would undergo bridges (the way in which side-chains work now). This is able to additionally imply that they both:
-
must cut up block rewards (requires change in protocol to decrease Earth’s bitcoin reward let’s say 50% whereas Mars side-chain would begin rewarding the opposite 50%) with a view to stability issuance between parallel chains.
-
or Mars must rely solely on charge mining (which may make on-chain transactions on Mars costlier relying on when would that occur as reward is declining exponentially, it additionally depends upon how usually Martians would transact on-chain evaluating to Earthlings)
UPDATE:
forgot a very powerful factor, power. Any colony on Mars could be primarily depending on power from Earth as a result of dependence on meals. Human work must be performed with a view to produce electrical energy, even when it runs on photo voltaic (upkeep could be wanted) or nuclear (uranium mining if any).
Dependence on meals imports results in (oblique) full dependence of hypothetical Martian crypto-miners from Earth. This mainly means, no unbiased PoW will be arrange on Mars.
Taking Arabic world (dependence on meals imports) as a fundamental instance of successfully dependent colony, including prices of house journey between Earth and Mars – massive colony could be unsustainable.
We will have some equal of Arctic stations there, however undoubtedly not full-scale free-market capitalist economic system.
So, lightning community is the one financial selection, side-chains with their very own mining rigs could be waste of electrical energy.
And even LN resolution solely holds underneath your assumption “we are able to construct settlements on Mars, massive sufficient to permit developed capitalist economic system”, which suggests we’ve got sufficient fundamental assets (meals and shelter) to take care of human species on Earth, or (simply to exclude naive Marxism/socialist “hope for somebody to present it to you” connotations), you personally are able to sustaining your individual life as human. After which investing vital chunk of your earnings into Mars (not essentially sarcasm right here – see under).
Within the meantime, there’s extra attention-grabbing state of affairs in case of “voluntary human extinction”. Since, not having children (to recursively pay your money owed 🙂 ) would free assets and make assets extra accountable, however nonetheless finite and diminishing, it will open prospects of constructing “finite lifetime” settlements on different celestial our bodies with zero-connections to Earth. Simply sufficient meals and shelter to outlive till you’re 80 or one thing. It could nonetheless want “free market and personal property” since life isn’t restricted to meals and shelter.
So, such “panda” settlement economic system would solely want a “channel manufacturing facility”: an remoted set of lightning channels between events with virtually no have to sync with blockchain on Earth. Fastened diminishing finances can enable for less-overthought and extra manageable P2P designs.
