> If an attacker has access to the cable outside your home they have already won, it's game over. Not if I'm looking at the block times or PoS participation rates. The attacker can feed me their own fork while preventing me from seeing the actual highest-difficulty chain, but their fork will be suspiciously weak, so I'll know not to trust it. > Block creation have high variance. Over short periods of time, say a few hours no blocks being announced is fairly common. Over long periods of time how do you know the mining power has not decreased or increased at a slow rate than your person prediction. Yeah; with Bitcoin you would need to wait several hours to get a good estimate of hash power. With more granular blockchains like Ethereum you could get a good estimate more quickly.
