 <\/p>\n

Quantum computing is here.\u00a0 Google made it work with a 53 qubit processor called Sycamore cooled to nearly absolute zero.\u00a0 The 3 minutes and 30 seconds of calculations done would take 100,000 computers 10,000 years to replicate<\/a>.\u00a0 IBM says that their own 53 qubit processor,<\/a> with conventional engineering, could replicate Google’s results in 2 1\/2 days. It appears that the 100,000 ordinary computers were left in the dust.\u00a0 Google’s process is still much faster than IBM’s, but they have to overcome heat to make it commercially viable.<\/p>\n

Last year, Aleksey Federov and two co-authors wrote in Nature<\/a> that quantum computing would be render Blockchain obsolete within a decade.\u00a0 Less than a decade has gone by, and the means of Blockchain’s obsolescence are already in two different places.<\/p>\n

Is Blockchain obsolete?\u00a0<\/p>\n

The answer to this question has two parts.\u00a0 Technologically, Blockchain is obsolete.\u00a0 The best from an era of 2 dimensional computing will not work in an era of 3 dimensions.\u00a0 It might be incorporated into a new protocol, but it will not stand alone. The era that began in October, 2008 with Satoshi Nakamoto’s paper lasted for exactly 11 years.\u00a0 It ended with Google’s breakthrough last month.\u00a0 Blockchain is on the way out.\u00a0 From a conceptual standpoint, however, Blockchain is viable.\u00a0 Proof of work, sovereign identity and networks without a central authority remain valid concepts.\u00a0 Blockchain will continue but in a different form.<\/p>\n

Enter the Blockyball or the Blockhelix<\/strong><\/p>\n

If Blockchain is a chain, then the 3 dimensional version will likely resemble a Buckyball or a DNA helix.\u00a0 Quantum computing will require quantum security. The concepts behind it and the possibilities they offer will likely remain the same.\u00a0 One can think of it in terms of past innovations.\u00a0 In 1984, MacWrite looked a lot like current word processors<\/a>, such as GoogleDocs and Microsoft Word.\u00a0 Using it today would be about the same as anything else, but the underpinnings are different.<\/p>\n

The Developers’ Dilemma<\/strong><\/p>\n

The 3 dimensional aspect of quantum computing is great, but developers can only code one line at a time.\u00a0 It is likely that computers will aid human developers in creating 3D code that will harness the potential of quantum computing.<\/p>\n
