Excellent idea, that gets the incentives right. RE: fixing the root cause with a forking change: What do other people think? I think it is too high risk for too little benefit and shouldn't be done until we have a really compelling reason to introduce a forking change. The first really compelling reason I can think of is removing the MAX_BLOCK_SIZE limit (but does something clever to prevent the rogue-miner-sends-you-a-valid-10Terabyte-block attack). -- -- Gavin Andresen
