Facebook moves into global banking

This morning’s Observer column:

We’ve known for ages that somewhere in the bowels of Facebook people were beavering away designing a cryptocurrency. Various names were bandied about, including GlobalCoin and Facebook Coin. The latter led some people to conclude that it must be a joke. I mean to say, who would trust Facebook, of Cambridge Analytica fame, with their money?

Now it turns out that the rumours were true. Last week, Facebook unveiled its crypto plans in a white paper. It’s called Libra and it is a cryptocurrency, that is to say, “a digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units and verify the transfer of assets”.

Like bitcoin, then? Er, not exactly…

LATER Merryn Somerset Webb of the Financial Times had a really good column ($) about the Facebook venture. Among the points she raises are:

  • Real cryptocurrencies are about privacy and freedom. They are decentralised and permissionless — no one runs them, no one can be prevented from using them and the system never needs reference to a central authority. (This last assertion is dubious — see Vili Lehdonvirta’s Turing Institute talk — but we will leave that pass for now.) Libra is to be none of these wonderful things. It is to be run by a single organisation based in Switzerland. It is centralised and permissioned — and its value will not depend on anything intrinsic to it but to a basket of fiat currencies.

  • The interest from the deposits and government bonds that back Libra will not go to the people holding the currency. It will be used to pay for the system’s operating costs and, once those are covered, to the founding members as dividends.

  • There are real privacy concerns raised by Libra, especially in relation to Facebook’s role in it in relation to the metadata that Libra will throw up. “If you are worried about the way financial apps might use data on your spending patterns, you should be really worried about how a vast social network morphing into a financial network might use it. Anyone with your social media data can guess what you might buy. Anyone with your financial data knows already.”

  • If Libra really is based on a basket of fiat currenties and is stable as a result, it might not take long for us to refer to the value of things in Libras. A Libra could just be a Libra. That, says Webb, “is a sovereignty game-changer”.

  • If Libra succeeds, it won’t because it’s a real cryptocurrency. It’ll be because it isn’t.
