I don't think that's what John means. If you have hash power for the parent chain, mining invalid blocks for the merge-mined chain costs you nothing. Yes, they will be invalid, but you've lost nothing. The basic assumption underlying mining security is that it is more profitable to collaborate with mining a chain (and profit from the block payout) than to attack it. In the case of merged mining, this assumption is not valid. -- Pieter ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
