“In the post that follows I’m trying to develop what I see to be strong analogues to another crucial period/turning point in the history of technology, but like all such comparisons, the differences are as illuminating as the similarities.”
New methods to counter attack fraud.
“We have introduced the possibility of using blockchain technology to create a seamless and continued global process for the KP certification scheme,” he said.
Blockchain is one of the most significant elements of the revolution in financial technology – fintech – that has been enthusiastically adopted by the UAE. Both Dubai and Abu Dhabi are setting up centres of excellence in fintech.
Article repeats a lot of the knowns on QC such as bit v. Qubit; and finally provides some good info on pros and cons of Bitcoin and Lamport signatures technique with QC. However, the author didn’t seem to mention any of the work that D-Wave for example is doing with Block chaining. Also, I saw no mention of the work by Oxford on the logic gate which improve both the information processing performance and the security of information transmissions.
In a classical computer bits are used that can either be 0 or 1. In a quantum computer these bits are replaced with Qubits (quantum bits). These Qubits can be 0 or 1, or both at the same time. This is caused by a phenomenon in the quantum realm called superposition. At scales the size of an atom and small molecules, the spin of particles is not determined until it is observed. A pair of Qubits can be in any quantum superposition of 4 states, and three Qubits in any superposition of 8 states. In general, a quantum computer with n Qubits can be in a superposition of up to 2^n different states simultaneously (this compares to a normal computer that can only be in one of these 2^n states at any one time). Because of this, a quantum computer is able to perform computations at the same time, while classical computers perform computations one at a time.

I was a guest on the Robot Overlordz podcast again recently, and was asked about my post on Medium for KnowledgeWorks called “Preparing for Hybrid Schools and Jobs.” The conversation with Mike and Matt took some interesting turns, as always, and they g
ot me thinking about some really important questions when it comes to blockchain and society, namely: assuming blockchain lives up to it’s reputation as a ‘truth machine,’ as I refer to it in my post, or a ‘revolution,’ as the Tapscotts say, why is there now a need for a revolutionary technology to enhance trust?
Although blockchain has captured the attention of the financial, management consulting and consumer goods industries, it hasn’t quite taken hold in education yet. KnowledgeWorks has published a fantastic report on the possibilities. I suggest in my post that the rise of hybrid jobs will generate support for hybrid schooling, and blockchain may be the technology that is best suited to track and communicate qualifications. The World Economic Forum said it best: “Farewell Job Title, Hello Skill Set.” If we are to be evaluated on our skills and experience, we must have some reliable way of guarding and transmitting that information.
But why is it that we need to enhance trust among students and teachers, employees and employers? I think that the facts that college students (some who didn’t even graduate) owe massive student loans, though worker’s wages have gone stagnant, play into this tension. How can students trust schools to provide the education they need, considering the high cost and the gamble that it may never really be recouped?
We are beginning to see slight signals that things are changing, at least a little, on the remuneration side, and it’s possible that a truth machine could help restore trust to hierarchical relationships (student/university and employee/employer) that are extremely out of balance. But what is at risk in assuming a technology can reverse human corruption?
I like this article because I have for years looked at options to address the counterfeiting issues which is a extremely costly criminal industry around diamonds and artwork. As we have seen with synthetic diamonds in their use in QC and medical technology there is a lot that technology can do in addressing the counterfeiting issues as well as registration & certification space. Also, could registered & embedded serialized stones be another form of id for the consumer who wears their accessory with the stone? I believe it can be.
IBM launches a new high security blockchain service that uses hardware to protect valuable data, with provenance startup Everledger as its first customer.
I was asked this at Quora.com, where I answer questions under the pen name, ‘Ellery’. But the query deserves a companion question, and so I approached the reply by answering two questions.
You might have asked “Why was Bitcoin designed to have a cap?” But, instead, you asked “Why is the cap set at 21 million bitcoins”. Let’s explore both questions starting with the choice of a circulation cap…
Why set the cap at 21 million BTC?
The choice of a cap number is arbitrary and in fact, it could be 1 or it could be 1 hundred trillion. It makes no difference at all and it has no effect on the economy—even if Bitcoin were to be adopted as a currency all over the world. If it were set to 1 BTC, we would simply discuss nano-BTC instead of 1 BTC for amounts of about $650.
