From Nationwide customers 'bank cards suddenly stopped working' after technical glitch

The system went down. But what if there was no system to go down? Imagine that each ATM is a node in a shared ledger. Suppose a bank has a million customers, and each customer’s transaction record is 1Kb. A balance, last few transactions, that sort of thing. No need to store the whole transaction history in the ledger. That’s 1Gb. Maybe 10Gb for all of the bank customers in the UK. I have a flash drive in my bag with 128Gb on it and it cost like $50. Now, when someone draws money from an ATM the ledger is updated over a few minutes at all of the other ATMs (remember, ATMs are doing nothing most of the time). If an ATM goes down, so what? Just go to another one. When an ATM comes back, the ledger will update.

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.

Crystal clear: Creating hyper-transparent property markets - JLL Real Views

xxx The issue of transparency is going to play a major role in the allocation of an avalanche of global commercial investment into real estate over the next decade. With total sums at stake predicted to rise from US$700 billion to over $1 trillion a year by the mid 2020s, according to JLL, countries and cities which meet investor demands on transparency will be best placed to attract these capital flows.
