On its side, Bitcoin is all about creating an "artificial" arrow of time.
This is achieved by continuously "injecting" a flow of energy into the system (a requirement for the apparition of dissipative structures).
@laurentmt Calculate the probability that a solved block unsolves itself sometime in the future.
The arrow of entropy is real, even if quantum mechanics says there's a highly improbable chance it could extricate itself.
@TallTim Agreed. Note that when I say "artificial" it doesn't mean that this arrow of time isn't real but that it's the result of an artifact, of a tool built by human beings.
@laurentmt I'm increasingly convinced that time is only an artifact of our perception. We are serial processors, after all. A bit hard to contemplate parallelism with our limited cognition.
