POSY Quantum

I saw a fascinating presentation by Ursula Schilling on Infineon on “Securing the Quantum Computer World” in which said was talking about the need to develop cryptography that will be resistant to attacks from quantum computers. It’s a live topic, because if the figures she presented are approximately correct and there will be quantum computers capable of making practical attacks on RSA/ECC with 15-20 years, that means that information currently being secure using asymmetric cryptography (eg, Bitcoin) is essentially being put into the public domain!

new survey results from USA Technologies (USAT) suggest. The payments technology company, which enables electronic payments for self-service machines, compared consumer spending activity at 35 of its vending machines in urban areas with a high concentration of iPhone users between week one and week four of the installation of new digital signage promoting Apple Pay. Consumers made more contactless purchases: The vending machine providers saw an average contactless transaction revenue increase of 89%, implying that consumers are making more mobile payments. This was likely driven by the clear advertisement of Apple Pay. Total transactions increased: Consumers made more purchases overall. This was probably driven by an uptick in mobile payments, given the major increase in contactless transaction revenue. And the vending machines may have attracted many first-time users who were drawn in by the digital advertising of Apple Pay. Boosting awareness is key to unlocking pent-up demand amon...

Alex Todd rather kindly called this a “most lucid explanation of digital identity management” I would highly recommend this presentation to anyone interested in understanding prospective blockchain based identity architectures From David | LinkedIn This is very kind, but as I said in the link, this is thinking out loud and far from a fully-developed solution. We’re working on parts of this for different clients and I can see that there is something there - a genuinely new way of solving some old problems - but it’s early days.

Financial Cryptography: Corda Day - a new force

Forum friend Ian Grigg, who I always take very seriously indeed on any such topic, wrote about Corda on his blog and concluded with a powerful statement. Bitcoin told the users it wanted an unstoppable currency - sure, works for a small group but not for the mass market. Ethereum told their users they need an unstoppable machine - which worked how spectacularly with the DAO? Not. What. We. Wanted. Corda is the only game in town because it's the only one that asked the users. It's that simple. From Financial Cryptography: Corda Day - a new force xxx It seems to me, however, what Ian is pointing to as the greatest strength of their approach is also the greatest weakness. A staple feature of unimaginative management consultants presentations about innovation is some variation on the statement by Henry Ford that if you had asked users what they wanted, they would have asked for faster horses coupled with some variation on the statement by Steve jobs that it was pointless ask...
