This would only be the case if the attacker openly hijacks the entire TCR. If it’s a more subtle attack to get a specific entry listed or upvoted, the TCR would not immediately lose its value. In addition, I believe that the majority of ‘honest tokens‘ will almost always be in several hands, so coordination will be necessary for the counterattack. The attacker has a much easier game communicating the incentive (unidirectional one to many), where an honest (minority) defender would have to motivate several others to join forces and actually communicate their commitment. Thus, even in a token weighted voting system I do believe there is room for bribery that won’t kill the TCR but allow attackers to gain an advantage. However, I could imagine a system in which anyone could challenge the outcome and enforce a second voting round with a much large number of voters – thereby rendering the attack very expensive.
