Mars will start its own chain: https://unchained.com/bitcoin-astronomy/the-law-of-hash-horizons
I don't think this is a reasonable approach to the problem. In this model there is a massive avenue for attacks to occur against "Muskcoin" while the hashrate is small. Additionally, with the manufacturing head start that Earth has over Mars, Earth would be able to over produce Asics for Muskcoin and the hash-center of Muskcoin would likely also be on earth not solving anything.

So everyone just uses Bitcoin?

I think its reasonable to consider lengthening the average block time to give Mars miners a fair chance of being within the hash horizon. I think it's the least combative option even though it does include a hard fork. Especially as the use of main chain adapts in the future I would expect it to be reasonable to allow blocks every ~30-40min to allow miners on Mars to have a fair chance

I don't understand the scenario here. Does Earth have an adversarial relationship with Mars or is it cooperative? Why would Earth miners censor Martian transactions if they are paying the fee?
reply
The point is that they could. It would be a permissioned network on Mars completely at the whim of Earth.
I don't see why Earth <=> Mars relations would end up any different than how the relationships of countries on earth work, sometimes good, sometimes bad.
reply
But by that logic it's a permissioned network at the at the whim of Earth miners now as well. Yet they mine my transactions without even checking if I'm an Earthling, just because I pay the going rate.
reply
You're right, but I am reasonably able to build and maintain a miner which could find a block without having to travel to another planet if my transactions were not getting mined.

My point is miners don't know they are Martian txs, and there would be relay services that accept encrypted Martian txs in order to rebroadcast them on Earth.
Even today mining your own txs is unrealistic. To get into a block in the next week you would need ~1/1000th of total network hash rate, i.e. ~600 PH/s - that's equivalent to about 2000 Bitmain s21 miners and the power to run them.
He mentions testing the network pre-genesis against earth hash-bombs. But part of the beauty of Bitcoin is it's release schedule, combined with it's growth in popularity.
