There are large mining facilities in central Washington and Tibet and elsewhere that would have an energy budget like a Facebook facility or supercomputing center. Because mining gets more competitive in time, the power budgets keep going up. For example, running five modern bitcoin miners nonstop will yield a power bill of about $700 a month. Multiply that by hundreds and you get the idea..

A friend is a bitcoin miner and he uses four computers, with four heavy duty graphics processors - all water cooled to do so. A lot of computing power but still within the budget of an individual - no where near that of a "small country." davew On Fri, Mar 10, 2017, at 08:09 AM, Robert J.

'Blockchain entities like Bitcoin are distributed among lots of different players require a lot of power (computing and literal) to compile and check — as much as a small country,' - Really? So there's no way to hack a blockchain? Or perhaps I should say why is it so secure? *http://www.theverge.com/2017/3/10/14880094/deepmind-health-uk-data-blockchain-audit Robert C -- Cirrillian Web Design & Development Santa Fe, NM http://cirrillian.com 281-989-6272 (cell) Member Design Corps of Santa Fe ============================================================ FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College to unsubscribe http://redfish.com/mailman/listinfo/friam_redfish.com FRIAM-COMIC http://friam-comic.blogspot.com/ by Dr. Strangelove
