Incentive-Based Attack Threatens Any Blockchain, Including Bitcoin

I think this attack can work on any blockchain — it’s not limited to small networks. The vector exploits economic incentives, so where miners or validators can capture superior rewards they may follow the scam.

In my view, smaller chains and those with weaker decentralization could suffer worse consequences, but Bitcoin is not categorically immune: if miners prioritize short-term profit over protocol integrity, attacks become feasible.

I’m concerned by the assumption that miners are motivated primarily by ideology; in practice economic incentives drive behavior and can undermine security.
