Beyond blockchain: what are the technology requirements for a Central Bank Digital Currency? – Bank Underground

Writing in the Bank of England’s “Bank Underground” blog, Simon Scorer from the Digital Currencies Division, makes a number of very interesting points about the requirement for some form of Central Bank Digital Currency (CBDC). He remarks on the transition from dumb money to smart money, and the consequent potential for the implementation of digital fiat to become a platform for innovation (something I strongly agree with), saying that:

Other possible areas of innovation relate to the potential programmability of payments; for instance, it might be possible to automate some tax payments (e.g. when buying a coffee, the net amount could be paid directly to the coffee shop, with a 20% VAT payment routed directly to HMRC), or parents may be able to set limits on their children’s spending or restrict them to trusted stores or websites.

If digital fiat were to be managed via some form of shared ledger, then Simon’s insight here suggests that it is not the shared ledger but the shared ledger applications (what some people still, annoyingly, insist on calling “smart contracts”) that will become the nexus for radical innovation.

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...

David | LinkedIn

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...
