I'm curious about this point. Is this true? Does the energy cost increase in proportion to the hardware cost? It seems like bitcoin mining hardware becomes much more energy efficient with each new generation.
Could you link to a source?

- gnopgnip 12y agoIf bitcoin mining hardware gets more energy efficient, it is more efficient for the attackers too. The symmetrical costs are the problem here.
- FatalLogic 12y agoThanks, but I wasn't commenting on that really, just the point I asked about.
- danbruc 12y agoThe mining efficiency - hashes per Joule - is unimportant. The important quantity is power consumption over hardware price and I admittedly just eyeballed that from the linked mining hardware list [1].

See my response to your first comment - you can not simply prevent any 51 % attack by changing the protocol. By the way, I am not downvoting your comments, I am (usually) not voting on any responses to me but let the other users judge.
