A deep dive into blockchain and Bitcoin
Blockchain technology promises to solve many complex problems across different business sectors and industries, and Bitcoin is breaking value records seemingly every hour. But many don’t understand how the two really work, and use the two words interchangeably as if they were synonymous.
One important thing to remember is that blockchain can exist without Bitcoin, but Bitcoin cannot exist without a blockchain.
Bitcoin is a digital currency that was created in 2009. Only 21 million Bitcoins can ever be created (mined), and it is estimated that the last coin will be produced in 2140.
It is exchanged on a decentralized, peer-to-peer network, meaning that there is no central server or authority (i.e., a central bank) that regulates it. In the beginning, the Bitcoin network was operated by volunteers who had a full Bitcoin protocol stack installed on their private computers. However, the network’s operation has mostly been taken over by specialized data centers.
Bitcoin operates on a cryptographic protocol, is fully transparent and open source. As it’s not backed by a real authority, the health of the system depends entirely on the trust people have in it. The value of Bitcoin is determined by the amount people are willing to pay for it.
Google expands work in quantum computing with 72-qubit Bristlecone processor
Bristlecone is the evolution of Google´s prior 9-qubit linear quantum processor, which had error rates of 1% for readout, 0.1% for single-qubit gates, and 0.6% for two-qubit gates.
Crypto-gurus: Which idiots told the FBI that Feds-only backdoors in encryption are possible?
The four are: Stanford professor Martin Hellman, of Diffie-Hellman fame and who helped invent the foundations of today´s crypto systems; Columbia professor and USENET co-creator Steve Bellovin; top cryptographer Paul Kocher; and information security guru Bruce Schneier.
All four this week signed a letter (link in article) to Senator Ron Wyden (D-OR) applauding his "effort to find out with whom the bureau has been consulting and which cryptographic experts believe an exceptional access system can be built securely."
Report finds little being done about security threat posed by quantum computing

Did Codebreakers Crack This Mysterious Medieval Manuscript?
A pair of Canadian codebreakers may have deciphered a 600-year-old book that has been baffling cryptologists for centuries. But, more likely, they probably haven't.
In a study published in the journal Transactions of the Association of Computational Linguistics, computing scientists from the University of Alberta used an algorithm to try to decode parts of the Voynich Manuscript, a medieval book written in an undecipherable code with an unknown language.
But other scholars are skeptical, and the manuscript remains a document very much shrouded in mystery.
