"High" is relative. I could make a 100BTC apparently sacrifice via fees by just waiting a month or two for my mining hardware to find a block that had a pre-prepared fake sacrifice. It'd cost me roughly 1BTC when you take orphans into account. Similarly I could hack into a pool and have them do it on my behalf, or a pool could just offer the service for a fee. I already worry enough that announce-commit sacrifices to mining fees aren't secure enough given the potential of a few large pools teaming up to create them cheaply, let alone what you're talking about... Hey Luke: so what's the going rate to get Eligius to mine a fake mining fee sacrifice? Can I get a discount on repeat orders? :) -- 'peter'[:-1]@petertodd.org 000000000000014c5bfacfca559fd6a9519dcd338f9fca6590eda7d156120013
