| 1) It's not related to bitcoin energy usage, which is designed to be high. This is based on the current best science has to offer in making things cheap. The 100x multiple is to the cost of normal computation. Normal, unsecured, visible to your hosting provider, etc, computation. Companies already pay huge amounts for securing computation so a pure mathematical way to do it that's only 100 times the base cost of the CPU time is actually a huge savings to many. You don't have to run your whole webserver this way, just the payment processing pieces... 2) What will happen is pure guessing because it depends on the hidden motives of others via market (and other) dynamics. But the options are roughly, A) The bitcoin blockchain remains at today's general capacity. In this case the price per blockchain/byte will increase and people will use side-chains and "link" them back in as they feel appropriate. You will have the option of downloading sidechains you care about. B) The bitcoin users decide on one of the proposals to increase the blockchain capacity dramatically - and all of these offer some form of prunability so you don't need to hold the GBs of stuff you don't care about in order to strongly verify the things you do care about (like the balance of someone who's paying you)... C) Some other currency which solves these things really is the "one". But these questions didn't need asking. They're needlessly critical - as if technologies should (or even could) all be invented at greater than 100% ROI just out of thin air, and as if market dynamics wouldn't handle things anyway. If this solution is too expensive, nobody will use it. There are no externalities involved here, nobody is getting a free lunch; they'll only pay for it if it helps them overall. |
