      @taoeffect an attacker with the capabilities to pull off the attack you describe can just as easily confuse either system

      .@taoeffect how can software automatically detect you have the wrong block chain if the Internet is lying to you?

      .@bascule As with anything else, it cannot. That doesn’t make the properties of blockchains and CT equivalent.

      @bascule Yes, but they do it in different ways, and the blockchain actually protects you from the MITM attack.

          The cost of constructing such a false reality would be generating a considerable amount of proof work on namecoin? @taoeffect @bascule

          @zmanian @bascule now hash rate can’t be detected either, well, we’re back to 100% censored 24/7 MITM, which no system can beat.
