To do this there is now <a href=\"https:\/\/www.bitcoinmining.com\/bitcoin-mining-hardware\/\">custom hardware<\/a>.\u00a0 Graphics cards and &#8220;normal&#8221; supercomputers have their theoretical power measured in FLOPS (there&#8217;s other better measures, I think FLOPS is the BMI of supercomputing). The important point here is that it stands for &#8220;Floating point operations per second&#8221;. A <a href=\"https:\/\/www.youtube.com\/watch?v=tgbkN9vb__8\">floating point number<\/a> is basically the same as scientific notation. A number and then the number of times to shift the decimal point left or right. Bitcoin mining uses hardware optimised specifically for <a href=\"https:\/\/en.wikipedia.org\/wiki\/Integer\">integer<\/a> operations, rather than floating point.<\/p>\n<p>Why does this matter?<\/p>\n<p>Well, it seems reasonably likely that Bitcoin might crash and make the vast amount of bespoke hardware deployed to mine it suddenly unprofitable. The owners will have the choice of scrapping\/mothballing it or to try and monetise it in other ways which would mean a sudden glut of availability of processing power for integer tasks (unlike the more common\u00a0 FLOPS). Maybe that&#8217;s something we should be preparing for? Could it have a significant impact on commodity data processing? Maybe there&#8217;s going to be a window where\u00a0\u00a0 teams with tasks\u00a0 that can run on such hardware can get very good deals&#8230; until everyone else catches up.<\/p>\n<p>I&#8217;m not experienced with supercomputing, so this is just a back-of-the-envelope theory.<\/p>\n<p>Is this a realistic scenario?
