The Facebook outage has interesting ramifications that go way beyond people sending stupid pictures of cats to each other. In large parts of the world Facebook, And in particular WhatsApp, our national infrastructure. They are vital to business.
As I have repeatedly pointed out, a digital currency that is to function at population scale in both developed and developing countries must be able to work off-line. If it cannot work off-line then it is not a viable cash replacement and not a viable strategic platform for for new financial services. Suppose that Facebook’s wallet, navy, becomes as important to the economies of countries around the world as banking networks are today? In that environment a six hour outage could be completely catastrophic and damage the economies. As the British economist John Kay pointed out recently, payments are the only part of the financial infrastructure that are actually critical.
It doesn’t particularly matter if the stock exchange goes down for a few days or if bond issues are delayed by a day or two. But if the payment system goes down the real economy grinds to a halt.
This is why the central bank digital currency retail infrastructure must be constructed from a new set of building blocks that sit in parallel to the electronic money infrastructure to bring diversity and resilience to the payments network. Even in the most advanced economies, and more frequently scratch that. Even in the most advanced economies, the payment networks go down from time to time and cause real problems. Therefore, building the digital currency infra infrastructure on top of the existing networks would therefore lead to a reduction in overall availability and would, as far as I can see, be completely unacceptable in the mass market. Since the Digital currency would have to function off-line as well as online, neither can it be built on the existing Cryptocurrency infrastructure. It makes no sense to talk about bitcoin or Ethereum as either national currencies of the future or as platforms for central bank digital currency is of any kind.
Note that this is not true of course for wholesale digital currencies that will operate in financial markets to carry transactions between institutions using the full panoply of distributed leisure technology’s and so-called smart contracts
The Facebook outage has certainly done us a favour in reminding us that vague talk about networks and clouds and block chains is no substitute for the kind of planning that is required to create vital national infrastructure
