If traveling back in time were possible, people would have traveled back with ASICS to mine a ton of coins. This competition would have eventually led to people broadcasting all the blocks up until when time traveling was invented (say 200 years of blocks). This hasn't happened so. I think it's safe to say time travel to the past is not possible, or at least humans will never invent it.

Eh. I don’t think this is a convincing argument. It makes the assumption that a time traveling civilization would value bitcoin. Who’s to say time travel isn’t theoretically be invented in a post-bitcoin world, or by a non-human civilization somewhere in the universe?

The absence of evidence is not the evidence of absence. Saying that because something hasn’t happened yet, it’s clear time travel could never be possible simply isn’t a compelling argument. You could make that argument about a bunch of things.

The word 'may' was used used very intentionally. But it's a theory worthy of further conversation. 😁

Thanks for your input.

You're thinking in linear terms. It's not that something hasn't happened yet, it's that the current state of the world is X, which suggests that the world hasn't been altered by time travel.

Would you agree that it’s a possibility that the civilization that were to invent time travel would have no use for “money” and as such, would have no incentive to alter the bitcoin time chain?

No, money will always exist. Humans need a way to trade resources between each other

In a world where you could time travel, theft likely be the primary form of acquiring things, imo.

Then bitcoin will be even more important because it can be secured through secrets and time.

TBone 2y ago

Bitcoin is far more than money. This is not a valid argument.

Fair. Do you agree that it’s possible that the civilization that were to invent time travel could potentially have no real incentive to alter the bitcoin time chain? Who’s to say it’s relevant to them?
