Absolutely. It wholly depends on the security model, and economic-incentives model. Some use models simply don't care if the miner created a transaction that gave the fee to themselves. It might even be /encouraged/ to do this! Sure they are paying themselves, but given bitcoin network difficulty is so high, simply obtaining payments-go-myself-as-miner transactions is itself difficult. Producing an identity (my goal) or whatever is just fine, and in such case becomes simply an additional block reward -- an additional incentive to buy into this identity creation/management system. Or exchange "identity" with another token, for another data service of your choice. This is no longer a strict "proof of sacrifice" system, if such behavior is encouraged, but it is nonetheless valid. -- Jeff Garzik Senior Software Engineer and open source evangelist BitPay, Inc. https://bitpay.com/ ------------------------------------------------------------------------------ How ServiceNow helps IT people transform IT departments: 1.
